Decompression sickness (DCS; also known as divers' disease, the bends, aerobullosis, or caisson disease) describes a condition arising from dissolved gases coming out of solution into bubbles inside the body on depressurisation. DCS most commonly refers to problems arising from underwater diving decompression (i.e., during ascent), but may be experienced in other depressurisation events such as emerging from a caisson, flying in an unpressurised aircraft at high altitude, and extravehicular activity from spacecraft. DCS and arterial gas embolism are collectively referred to as decompression illness.
Kamanin Diary, 30 December 1964 In 1965, Komarov worked with Yuri Gagarin in supervising preparations for the flight of Voskhod 2, which carried out the first attempt of an extravehicular activity in outer space. These preparations included fitting of space suits on the cosmonauts and briefings for the spaceflight. In April of that year, Komarov toured Leningrad with Kamanin, Gagarin, Gherman Titov, Belyayev, and Leonov. Komarov also visited Petropavlovsk Fortress with Valentin Glushko where Glushko had conducted early rocket experiments in the early 1930s.
Life photographer Ralph Morse asked Armstrong why See was no longer assigned with him on the Gemini 8 mission, and Armstrong replied, "Elliot's too good a pilot not to have a command of his own." In October 1965 See was promoted to command pilot (first seat) of Gemini 9, with Charles Bassett as his pilot. The Gemini 9 mission was similar to the previous mission. An extravehicular activity (EVA) that used the astronaut maneuvering unit (AMU) was scheduled, and they would rendezvous with an Agena target vehicle.
The test was delayed by one day due to Lenoir succumbing to motion sickness. Then an underperforming oxygen regulator in Lenoir's suit caused them to cancel the extravehicular activity (EVA) entirely. It was the first time in the history of the space program that an EVA had been cancelled due to space suit issues. The STS-5 crew successfully concluded the 5-day orbital flight of Columbia with the first entry and landing through a cloud deck to a hard-surface runway, demonstrating maximum braking.
These plans included major advancements in spacecraft capabilities, including a two-person spacecraft, the ability to change orbits, the capacity to perform an extravehicular activity (EVA), and the goal of docking with another spacecraft. These represented major advances over the previous Mercury or Vostok capsules, and Korolev felt the need to try to beat the Americans to many of these innovations. Korolev already had begun designing the Vostok's replacement, the next-generation Soyuz spacecraft, a multi-cosmonaut spacecraft that had at least the same capabilities as the Gemini spacecraft.Schefter (1999), p.
The first woman in space was a Soviet cosmonaut. Valentina Tereshkova launched with the Vostok 6 mission on June 16, 1963. The second woman overall to go into space was also a cosmonaut: Svetlana Savitskaya in 1982 on the Soyuz T-7 mission. Savitskaya became the first woman to fly to space twice on the Soyuz T-12 mission on July 25, 1984, and the first woman to walk in space when she performed extravehicular activity (EVA) outside the Salyut 7 space station on the Soyuz T-12 mission.
His first space flight was in 1966 on Gemini 12 during which he spent over five hours on extravehicular activity. Three years later, Aldrin set foot on the Moon at 03:15:16 on July 21, 1969 (UTC), nineteen minutes after Armstrong first touched the surface, while command module pilot Michael Collins remained in lunar orbit. A Presbyterian elder, Aldrin became the first person to hold a religious ceremony on the Moon when he privately took communion. Upon leaving NASA in 1971, Aldrin became Commandant of the U.S. Air Force Test Pilot School.
During the advanced training and the mission specific training, astronauts will learn about the operation of specific systems and skills required associated with their assigned positions in a space mission. The mission specific training typically requires 18 months to complete for Space Shuttle and International Space Station crews. It is important to ensure the astronauts’ well-being, physical and mental health prior, during, and after the mission period. Proficiency maintenance aims to help the crew members to maintain a minimum level of performance, including topics such as extravehicular activity, robotics, language, diving, and flight training.
Gemini 12 (officially Gemini XII) With Gemini IV, NASA changed to Roman numerals for Gemini mission designations. was a 1966 crewed spaceflight in NASA's Project Gemini. It was the 10th and final crewed Gemini flight (Gemini 1 & Gemini 2 were unmanned missions), the 18th crewed American spaceflight, and the 26th spaceflight of all time, including X-15 flights over . Commanded by Gemini VII veteran James A. Lovell, the flight featured three periods of extravehicular activity (EVA) by rookie Edwin "Buzz" Aldrin, lasting a total of 5 hours and 30 minutes.
Lenoir supported the Space Shuttle program in the areas of orbit operations, training, extravehicular activity, and payload deployment and retrieval. Lenoir flew as a Mission Specialist on STS-5 (November 11–16, 1982), the first Space Shuttle flight to deploy commercial satellites, and logged over 122 hours in space. Following STS-5, Lenoir was responsible for the direction and management of mission development within the Astronaut Office. Lenoir resigned from NASA in September 1984, to assume a position with the management and technology consulting firm of Booz Allen Hamilton in Arlington, Virginia.
The Sokol space suit, also known as the Sokol IVA suit or simply the Sokol (), is a type of Soviet/Russian space suit, worn by all who fly on the Soyuz spacecraft. It was introduced in 1973 and is still used . The Sokol is described by its makers as a rescue suit and it is not capable of being used outside the spacecraft in a spacewalk or extravehicular activity. Instead, its purpose is to keep the wearer alive in the event of an accidental depressurisation of the spacecraft.
From April to August 1991, Clifford was assigned to the Astronaut Office Mission Development Branch where he participated in the design, development, and evaluation of Shuttle payloads and crew equipment having extravehicular activity (EVA) interfaces. From May 1994 to September 1995 he served as lead for space station vehicle/assembly issues. A veteran of three space flights, Clifford flew as a mission specialist on STS-53 in 1992, STS-59 in 1994, and STS-76 in 1996. He has logged 665 hours in space, including a 6-hour spacewalk.
Following STS-109, Grunsfeld served as an instructor in the Extravehicular Activity Branch, and worked on the Orbital Space Plane, exploration concepts, and technologies for use beyond low earth orbit in the Advanced Programs Branch. He served as NASA Chief Scientist assigned to NASA Headquarters from 2003 to 2004. In January 2012, he became the associate administrator for the Science Mission Directorate at NASA's headquarters in Washington, replacing Ed Weiler. Grunsfeld has been actively engaged in communicating space science topics to the public through interviews, public lectures, and television appearances.
Armstrong and Janet have a second son, Mark. In 1965, after the Soviets complete the first extravehicular activity (EVA), Armstrong is informed that he will command Gemini 8, with David Scott as the pilot. Prior to the mission, See and Charles Bassett are killed in a T-38 crash, deepening Armstrong's grief at the string of recent losses. Armstrong and Scott successfully launch on Gemini 8 and dock with the Agena target vehicle, but soon afterward, a malfunction causes the spacecraft to roll at an increasingly dangerous rate.
He completed 18 months of training before being qualified for flight. He was assigned to Kennedy Space Center in Florida where he was involved in Orbiter vehicle processing and testing and as a Capcom (including for the historic docking of Space Shuttle Atlantis with Space Station Mir in 1995). He is an expert in Extravehicular Activity (Spacewalk), Spacesuit design, and Rendezvous navigation. Some of his other qualifications include Robotic Manipulator System (Robot Arm) operations, on-orbit systems repair, computer networking, and as Shuttle re-entry flight deck engineer.
The Extravehicular Activity Development Flight Test – 05 (EDFT-05) consists of the payload bay hardware elements of Detailed Test Objective (DTO) 671, EVA Hardware for Future Scheduled Extravehicular Missions. EDFT – 05's main objective is to demonstrate International Space Station (ISS) on-orbit, end-to-end EVA assembly and maintenance operations. The other DTO's included in this test are DTO 672, Extravehicular Mobility Unit (EMU) Electrical Cuff Checklist and DTO 833, EMU Thermal Comfort and EVA Worksite Thermal Environment. Another objective is to expand the EVA experience base for ground and flight crews.
During Apollo15's return flight to Earth, Worden performed an extravehicular activity (EVA), or spacewalk, to retrieve film cassettes from cameras on the exterior of the spacecraft. It was the first "deep space" EVA in history, and remains the one that has taken place farthest from Earth. After their return, the crew became involved in a controversy over postal covers they had taken to the Moon; they were reprimanded by NASA and did not fly in space again. Worden remained at NASA until 1975 at the Ames Research Center, then entered the private sector.
After his selection as an astronaut candidate by JAXA in September 2009, Kanai arrived at Johnson Space Center later that month for NASA astronaut training. As one of the fourteen members of the 20th NASA astronaut class, he participated in Astronaut Candidate Training which includes scientific and technical briefings, intensive instruction in ISS systems, Extravehicular Activity (EVA), robotics, physiological training, T-38 Talon flight training, and water and wilderness survival training. Kanai was certified as an ISS astronaut in July 2011. In July 2015, he participated as an aquanaut in the NEEMO 20 crew.
This deprived Skylab of most of its electrical power and also removed protection from intense solar heating, threatening to make it unusable. The first crew deployed a replacement heat shade and freed the jammed solar panels to save Skylab. This was the first time that a repair of this magnitude was performed in space. Skylab included the Apollo Telescope Mount (a multi-spectral solar observatory), a multiple docking adapter with two docking ports, an airlock module with extravehicular activity (EVA) hatches, and the orbital workshop, the main habitable space inside Skylab.
Abercromby and Aquarius habitat technician Nate Bender performing communication checks during NEEMO 14 mission. As a biomedical engineer and deputy project manager for the Space Exploration Vehicle (SEV) project, Abercromby was part of a team designing and testing a new type of human space exploration vehicle. Abercromby was also a member of the Extravehicular Activity (EVA) Physiology, Systems and Performance project, which helped develop new spacesuits that will be safer, more efficient, and easier to use. Abercromby has also worked in NASA's Neurosciences Laboratory, Anthropometry and Biomechanics Facility, and Flight Mechanics Laboratory.
Scott and Irwin rode it to explore the area around the landing site during three periods of extravehicular activity (EVA). On August 2, before finishing the final EVA and entering the Lunar Module, Scott used a special postmarking device to cancel a first day cover provided by the United States Postal Service bearing two new stamps, whose designs depicted lunar astronauts and a rover, commemorating the tenth anniversary of Americans entering space. That cover was returned to the Postal Service after the mission, and is now in the Smithsonian Institution's National Postal Museum.
Hoshide taking a space selfie during extravehicular activity (EVA) on September 5, 2012, with the Sun behind him. In February 1999 Hoshide was selected by NASDA (now JAXA) as one of three Japanese astronaut candidates for the International Space Station (ISS). He started the ISS Astronaut Basic Training program in April 1999 and was certified as an astronaut in January 2001. Since April 2001, he has participated in ISS Advanced Training, as well as supporting the development of the hardware and operation of the Japanese Experiment Module Kibō and the H-II Transfer Vehicle (HTV).
The Mercury IVA, the first U.S. space suit design, included lights at the tips of the gloves in order to provide visual aid. As the need for extravehicular activity grew, suits such as the Apollo A7L included gloves made of a metal fabric called Chromel-r in order to prevent punctures. In order to retain a better sense of touch for the astronauts, the fingertips of the gloves were made of silicone. With the shuttle program, it became necessary to be able to operate spacecraft modules, so the ACES suits featured gripping on the gloves.
They spent a significant amount of time training in the spacecraft simulators. They flew back and forth to Kennedy Space Center, from which their spacecraft would be launched; to North Carolina to develop experiments to be conducted during the flight; and to McDonnell Aircraft in St. Louis, where the Gemini spacecraft was made. Contrary to Slayton's typical crew rotation, David Scott took See's place as the pilot of Gemini 8. According to his autobiography, Slayton did not assign See to Gemini 8 because he considered him as too out-of-shape to perform an extravehicular activity.
Harbaugh has a commercial pilot's license with instrument rating, and over 1600 hours total flying time. Selected by NASA in June 1987, Harbaugh became an astronaut in August 1988. His technical assignments included work in the Shuttle Avionics Integration Laboratory (SAIL), the Shuttle Remote Manipulator System (RMS), telerobotics systems development for Space Station, the Hubble Space Telescope servicing mission development, spacecraft communicator (CAPCOM) in Mission Control, and extravehicular activity (EVA) for the International Space Station (ISS). He was assigned as the backup EVA crew member and capsule communicator (Capcom) for STS-61, the first Hubble Space Telescope servicing mission.
The thesis which contains the design is currently at the Applied Physics Laboratory of the Johns Hopkins University. In 2004, Kludze and a group of NASA engineers developed the Extravehicular Activity Infrared (EVA IR) camera for space-walking astronauts. The EVA IR camera was designed to fulfill a critical inspection need for the Shuttle Program; the on-orbit IR Camera can detect crack and surface defects in the Reinforced Carbon-Carbon (RCC) sections of the Space Shuttle's Thermal Protection System. This camera may help discover and prevent some of the problems leading to the disintegration of the Space Shuttle Columbia.
The crew had a combined 111 years of flying experience and an average age of 48 years and 5 months. The crew was dubbed "The Geritol Bunch" for their high experience. During this maiden voyage of the spacecraft Challenger, the STS-6 crew conducted numerous experiments in materials processing, recorded lightning activities, deployed the first tracking and data relay satellite (TDRS-A), and activated three Getaway Specials. Peterson and Musgrave conducted the Shuttle program's first extravehicular activity (EVA) to test the new suit, the Shuttle airlock, and new tools and techniques for construction and repair outside a spacecraft.
As part of this activity, he directed an effort combining the resources of the Mission Control Center (MCC) Display Team and the Space Station Training Facility. The result was the creation of the Common Display Development Facility (CDDF), responsible for the onboard and MCC displays for the International Space Station, using object-oriented programming techniques. Following his second flight, he was assigned as Chief of the Computer Support Branch in the Astronaut Office supporting Space Shuttle and International Space Station Programs and advanced technology development. Following STS-103, he served as Chief of the Extravehicular Activity Branch in the Astronaut Office.
Gemini 9A launch from LC-19 The first mission objective was to dock with an Agena Target Vehicle, as had first been achieved on the Gemini 8 mission. Accomplishment was not possible because of a launch preparation error on the target vehicle. A second objective was a planned extravehicular activity (EVA), or "space walk", by the right-hand seat Pilot. The plan was for him to move to the rear of the spacecraft and strap himself into the Air Force's Astronaut Maneuvering Unit (AMU), a 'rocket pack' which would allow the pilot controlled flight, independent of the capsule's life support system.
STS-51 Discovery, (September 12–22, 1993) was launched from and returned to make the first night landing at Kennedy Space Center, Florida. During the ten-day flight, the crew of five deployed the Advanced Communications Technology Satellite (ACTS) and the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrometer on the Shuttle Pallet Satellite (ORFEUS/SPAS). Newman was responsible for the operation of the SPAS, was the backup operator for the RMS, and on flight day five conducted a seven-hour-five-minute spacewalk with Carl Walz. The extravehicular activity (EVA) tested tools and techniques for use on future missions.
During the only stand-up extravehicular activity (EVA) ever performed through the LM's top hatch on the lunar surface, Scott was able to make plans for the following day's EVA. He offered Irwin a chance to look out as well, but this would have required rearranging the umbilicals connecting Irwin to Falcon's life support system, and he declined. After repressurizing the spacecraft, Scott and Irwin removed their space suits for sleep, becoming the first astronauts to doff their suits while on the Moon. Aboard the Lunar Roving Vehicle Throughout the sleep period Mission Control in Houston monitored a slow but steady oxygen loss.
Schweickart with the life support backpack The Extravehicular Mobility Unit (EMU) backpack flew for the first time on Apollo9, used by Schweickart during his EVA.Carson et al 1975 This included the Portable Life Support System (PLSS), providing oxygen to the astronaut and water for the Liquid Cooling Garment (LCG), which helped prevent overheating during extravehicular activity. Also present was the Oxygen Purge System (OPS), the "bedroll" atop the backpack, which could provide oxygen for up to roughly an hour if the PLSS failed. A more advanced version of the EMU was used for the lunar landing on Apollo 11.
This combined with other evidence indicates that space suits behave similarly to springs while running, which in turn would decrease the cost of transport when compared to walking. A study by Christopher Carr and Dava Newman suggested that the cause of this spring-like behavior is knee torque, which means in motions that require a larger bend in the knee, the contributions from the space suit will be greater. The limitations on extravehicular activity (EVA) in space are related to the metabolic costs of locomotion in a spacesuit. Metabolic cost refers to the energy cost of a physical activity.
He took 38 minutes in extravehicular activity (EVA) outside Endeavour to accomplish this, three times venturing from outside the hatch to the exterior of the SIM bay of the SM. In retrieving the film cassettes from the panoramic and mapping cameras, Worden performed the first deep-space EVA, and reported his personal observations of the general condition of equipment housed there. Worden remains, , the record-holder for the EVA performed furthest from Earth. Apollo15 concluded with a Pacific splashdown and subsequent recovery by the amphibious assault ship USS Okinawa. In completing his flight, Worden logged 295 hours and 11 minutes in space.
Astronaut Buzz Aldrin, Lunar Module pilot of the first lunar landing mission, poses for a photograph beside the deployed United States flag during an Apollo 11 Extravehicular Activity (EVA) on the lunar surface. In total, twenty-four U.S. astronauts have traveled to the Moon. Three have made the trip twice, and twelve have walked on its surface. Apollo 8 was a lunar-orbit-only mission, Apollo 10 included undocking and Descent Orbit Insertion (DOI), followed by LM staging to CSM redocking, while Apollo 13, originally scheduled as a landing, ended up as a lunar fly-by, by means of free return trajectory; thus, none of these missions made landings.
Astronaut clothing for men has been based on technology used to make bras, and since women have been sent to space the previously men focused clothing has been reconsidered addressing the issues and needs for clothing like space suits for extravehicular activity (EVA) and bras, e.g. for exercise in micro-g environments. Low number of produced smaller sized space suits has been hindering women astronauts to do EVAs because of a lack of fitting suits. Furthermore space toilet designs did not have women in mind, until October 2020 when the first toilet with better design for women (as well as men) was delivered to the ISS.
If power closing had failed, Crippen was trained to conduct a one-man extravehicular activity (EVA) to manually winch them closed. With cabin switch positions verified, the crew strapped into their ejection seats. Meanwhile, JSC pilots Charlie Hayes and Ted Mendenhall were airborne over California's Edwards Air Force Base area in a Shuttle Training Aircraft (STA) performing a final check of landing weather conditions. Auxiliary Power Units (APUs) 2 and 3 were started (to provide flight control hydraulic pressure). The 160-second twin-engine OMS de-orbit burn took place during the 36th orbit over the southern Indian Ocean and changed the orbital parameters from to .
Also transferred to the station were Mir Glovebox Stowage (MGBX) equipment to replenish glovebox already on station; Queen's University Experiment in Liquid Diffusion (QUELD) flown in orbiter middeck locker; and the High Temperature Liquid Phase Sintering (LPS) experiment. On flight day six, Godwin and Clifford conducted what some claim to be the first U.S. extravehicular activity (EVA) around two mated spacecraft. However, this appears to ignore the Apollo 9 EVA, and EVAs during Skylab. During six-hour, two-minute, 28-second EVA, they attached four Mir Environmental Effects Payload (MEEP) experiments to the station's docking module - designed to characterize the environment around Mir over an 18-month period.
Lee was selected as an astronaut candidate by NASA in May 1984. In June 1985, he completed a one-year training and evaluation program, qualifying him for assignment as a mission specialist on future Space Shuttle flight crews. His technical responsibilities within the Astronaut Office included extravehicular activity (EVA), the Inertial Upper Stage, Spacelab, and Space Station systems. Lee also served as a spacecraft communicator in the Mission Control Center, as Lead Astronaut Support Person at the Kennedy Space Center, Chief of Astronaut Appearances, Chief of the Astronaut Office Mission Development Branch, Chief of the EVA Robotics Branch, and Chief of the EVA Branch.
Samokutyaev and cosmonaut Maksim Surayev performed a spacewalk outside the space station on 22 October 2014. Although planned as a six-hour spacewalk, the cosmonauts were able to complete all the scheduled tasks in 3 hours and 38 minutes. During the extravehicular activity, Samokutyaev and Surayev dismantled the RK 21-8 Radiometria science payload and the 2ASF1-1 and 2ASF1-2 KURS antennas from the Poisk module. The RK-21-8 science payload was installed aboard the Space Station during the Russian EVA-28 in early 2011 and consisted of an antenna system with calibrator, a Microwave Radiometer receiver system and a Command-Information Unit.
At age 29, Chiao was selected by NASA in January 1990 and became an astronaut in July 1991. He qualified for flight assignment as a mission specialist. His technical assignments included: Space Shuttle flight software verification in the Shuttle Avionics Integration Laboratory (SAIL); crew equipment, Spacelab, Spacehab, and payload issues for the Astronaut Office Mission Development Branch; training and flight data file issues; and extravehicular activity (EVA) issues for the EVA Branch. Chiao also served as Chief of the Astronaut Office EVA Branch. A veteran of four space flights, Chiao flew as a mission specialist on STS-65 in 1994, STS-72 in 1996 and STS-92 in 2000.
Sprint during STS-87 The Autonomous Extravehicular Activity Robotic Camera Sprint (AERCam Sprint) is a NASA experiment to demonstrate the use of a prototype free-flying television camera. It was tested on STS-87 and could also be used for remote inspections of the exterior of the International Space Station. The AERCam Sprint free-flyer is a , 35-pound (16 kg) sphere that contains two television cameras, an avionics system and 12 small nitrogen gas- powered thrusters. The sphere, which looks like an oversized soccer ball, was released by Mission Specialist Winston E. Scott during the STS-87 spacewalk and flew freely in the forward cargo bay for about 30 minutes.
He made two spacewalks with Jerry Ross, manually deploying the Compton Gamma Ray Observatory's radio antenna when it failed to do so automatically; on the next day their second spacewalk tested hardware later used on the International Space Station. During the second Extra Vehicular Activity the palm-bar in Apt's right glove punctured the suit."STS-37 Space Shuttle Mission Report May 1991 - NASA- CR-193062", Extravehicular Activity Evaluation, Page 16, accessed online 4 Jan, 2011 Apt's hand conformed to the puncture, filling the hole before any noticeable depressurization could occur. Apt was unaware of the puncture until the glove was examined after the mission.
The Voskhod space capsule, as flown in two variants The Vostok design was modified to permit carrying multi-cosmonaut crews, and flown as two flights of the Voskhod programme. The cyllindrical interior cabin was replaced with a wider, rectangular cabin which could hold either three cosmonauts seated abreast (Voskhod 1), or two cosmonauts with an inflatable airlock in between them, to permit extravehicular activity (Voskhod 2). A backup solid- fuel retro rocket was added to the top of the descent module. Vostok's ejection seat was removed to save space (thus there was no provision for crew escape in the event of a launch or landing emergency).
The NEEMO 15 crew. Left to right: Takuya Onishi, Shannon Walker, Saint-Jacques, Steve Squyres, and Aquarius habitat technicians Nate Bender and James Talacek. Saint-Jacques was selected in May 2009 by the Canadian Space Agency (CSA) as one of two CSA astronaut positions, after a long process selection attended by 5,351 candidates, and has moved to Houston to be one of 14 members of the 20th NASA astronaut class. He recently graduated from Astronaut Candidate Training that included scientific and technical briefings, intensive instruction in International Space Station systems, extravehicular activity (EVA), robotics, physiological training, T-38 flight training, Russian language and water and wilderness survival training.
From 1979 to 1983, Griggs was involved in several Space Shuttle engineering capacities including the development and testing of the Head-Up Display (HUD) approach and landing avionics system, development of the Manned Maneuvering Unit (MMU), and the requirements definition and verification of on-orbit rendezvous and entry flight phase software and procedures. In September 1983 he began crew training as a mission specialist for flight STS-51-D, which flew April 12–19, 1985. During the flight, Mr. Griggs conducted the first unscheduled extravehicular activity (space walk) of the space program. The space walk lasted for over three hours during which preparations for a satellite rescue attempt were completed.
She has logged over 975 hours in space, including more than 21 hours of extravehicular activity (EVA). Thornton was a mission specialist on the crew of STS-33 which launched at night from Kennedy Space Center, Florida, on November 22, 1989, aboard the Space Shuttle Discovery. The mission carried Department of Defense payloads and other secondary payloads. After 79 orbits of the Earth, this five-day mission concluded on November 27, 1989, at Edwards Air Force Base, California. On her second flight, Thornton served on the crew of STS-49, May 7–16, 1992, on board the maiden flight of the new Space Shuttle Endeavour.
Russian engineers used an air-like nitrogen/oxygen mixture, kept at a cabin altitude near zero at all times, in their 1961 Vostok, 1964 Voskhod, and 1967 to present Soyuz spacecraft. This requires a heavier space vehicle design, because the spacecraft cabin structure must withstand the stress of 14.7 pounds per square inch (1 bar) against the vacuum of space, and also because an inert nitrogen mass must be carried. Care must also be taken to avoid decompression sickness when cosmonauts perform extravehicular activity, as current soft space suits are pressurized with pure oxygen at relatively low pressure in order to provide reasonable flexibility.Gatland, p.
In 1976 Weitz retired from NASA and went back the Navy, but he returned to NASA to fly the maiden spaceflight of the Challenger at over 50 years old. Weitz and Donald H. Peterson (right) aboard Space Shuttle Challenger during the STS-6 mission Weitz was spacecraft commander on the crew of STS-6, which launched from Kennedy Space Center, Florida, on April 4, 1983. This was the maiden voyage of the orbiter Challenger. During the mission, the crew conducted numerous experiments in materials processing, recorded lightning activities, deployed IUS/TDRS-A, conducted extravehicular activity while testing a variety of support systems and equipment in preparation for future spacewalks, and also carried three Getaway Specials.
EVA on simulated asteroid during NEEMO 15 mission. In February 2009, Onishi was selected by the Japanese Aerospace Exploration Agency (JAXA) as one of the Japanese astronaut candidates for the International Space Station (ISS). Starting in April 2009, he attended the ISS Astronaut Basic Training domestic program at Tsukuba Space Center in Japan. Onishi arrived at NASA's Johnson Space Center in Houston, Texas, in August 2009. As one of the fourteen members of the 20th NASA astronaut class, he took part in an Astronaut Candidate Training program that included scientific and technical briefings, intensive instruction in ISS systems, Extravehicular Activity (EVA), robotics, physiological training, T-38 Talon flight training, and water and wilderness survival training.
During Atlantis stay crew members Titov and Parazynski conducted the first joint US–Russian extravehicular activity during a Shuttle mission, and the first in which a Russian wore a US spacesuit. During the five-hour spacewalk, the pair affixed a Solar Array Cap to the Docking Module, for a future attempt by crew members to seal off the leak in Spektr hull. The mission returned Foale to Earth, along with samples, hardware, and an old Elektron oxygen generator, and dropped Wolf off on the Station ready for his 128-day Increment. Wolf had originally been scheduled to be the final Mir astronaut, but was chosen to go on the Increment instead of astronaut Wendy Lawrence.
Mattingly and his commander from Apollo 16, John Young, are the only people to have flown to the Moon and also a Space Shuttle orbital mission (Fred Haise, his former training crewmate from Apollo 13, did atmospheric flight testing of the Space Shuttle "Approach and Landing Tests"). During Apollo 16's return flight to Earth, Mattingly performed an extravehicular activity to retrieve film cassettes from the exterior of the spacecraft, the command and service module. It was the second "deep space" EVA in history, at great distance from any planetary body. As of , it remains one of only three such EVAs which have taken place, all during the Apollo program's J-missions.
Twenty-six separate scientific experiments were conducted both in lunar orbit and during cislunar coast. Major emphasis was placed on using man as an orbital observer, capitalizing on the human eye's unique capabilities and man's inherent curiosity. During the return leg of the mission, Mattingly carried out an extravehicular activity (EVA) to retrieve film and data packages from the science bay on the side of the service module. Although the mission of Apollo 16 was terminated one day early, due to concern over several spacecraft malfunctions, all major objectives were accomplished through the ceaseless efforts of the mission support team and were made possible by the most rigorous preflight planning yet associated with an Apollo mission.
Given three crew-rotation missions per year, each one would have to carry between three and four tonnes of down cargo. Team 2 calculated that this could be done by scaling up the HL-20 design by a factor of 1.42, coincidentally giving it a length of 42 feet (and the name HL-42). The combined mass of crew and cargo was set at 4.2 tonnes. The baseline annual up cargo manifest would then look like this: Figure 19 from the Access to Space Study Summary Report On the downward journey this manifest would return 78 mid-deck lockers, all extravehicular activity suits, and approximately 65 percent of the user pressurized racks (ISPRs).
The first American woman in space was Sally Ride, during Space Shuttle Challenger's mission STS-7, on June 18, 1983. In 1992 Mae Jemison became the first African American woman to travel in space aboard STS-47. Cosmonaut Alexei Leonov was the first person to conduct an extravehicular activity (EVA), (commonly called a "spacewalk"), on March 18, 1965, on the Soviet Union's Voskhod 2 mission. This was followed two and a half months later by astronaut Ed White who made the first American EVA on NASA's Gemini 4 mission. The first manned mission to orbit the Moon, Apollo 8, included American William Anders who was born in Hong Kong, making him the first Asian-born astronaut in 1968.
Once selected, NASA astronauts go through twenty months of training in a variety of areas, including training for extravehicular activity in a facility such as NASA's Neutral Buoyancy Laboratory. Astronauts-in-training (astronaut candidates) may also experience short periods of weightlessness (microgravity) in an aircraft called the "Vomit Comet," the nickname given to a pair of modified KC-135s (retired in 2000 and 2004, respectively, and replaced in 2005 with a C-9) which perform parabolic flights. Astronauts are also required to accumulate a number of flight hours in high-performance jet aircraft. This is mostly done in T-38 jet aircraft out of Ellington Field, due to its proximity to the Johnson Space Center.
During the space walk, Foale remained inside the Soyuz capsule attached to Mir, in constant communication with the cosmonauts as well as ground controllers. On 5 September, Foale and Solovyev conducted a six-hour external extravehicular activity to survey damage outside Spektr and to try to pinpoint where the breach of the module's hull occurred. Two undamaged arrays were manually repositioned to better gather solar energy, and a radiation device left previously by Jerry Linenger was retrieved. The docking of Atlantis and Mir took place at 3:58 pm EDT, 27 September, with the two mission commanders opening the spacecraft hatches at 5:45 pm Wolf officially joined the Mir 24 at noon EDT, 28 September.
He would also have to go rescue the LM if it could not perform the rendezvous, and if it could not dock, would have to assist McDivitt and Schweickart in performing an extravehicular activity (EVA) or spacewalk, back to the CSM. Scott was somewhat unhappy, though, that CSM-103, which he had worked on extensively, would stay with Apollo 8, with Apollo 9 given CSM-104. Scott stands in the open hatch of the Apollo 9 Command Module Gumdrop The planned February 28, 1969 launch date was postponed as all three astronauts had head colds, and NASA was wary of medical issues in space after problems on Apollo 7 and 8. The launch took place on March 3, 1969.
Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley Rille and explored the local area using the rover, allowing them to travel further from the lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on extravehicular activity (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moon, operating the sensors in the SIM bay of the service module. This suite of instruments collected data on the Moon and its environment using a panoramic camera, a gamma-ray spectrometer, a mapping camera, a laser altimeter, a mass spectrometer, and a lunar subsatellite deployed at the end of the moonwalks.
The original extravehicular activity (EVA) plan, up through at least 1966, was for only one astronaut to leave the LM while the other remained inside "to maintain communications".Landing on the Moon, 1966 episode of MIT's Science Reporter (posted to YouTube by MIT on Jan 20, 2016) Quote: "While one astronaut explores the area around the LEM, the second remains inside to maintain communications." Communications were eventually deemed to be reliable enough to allow both crew members to walk on the surface, leaving the spacecraft to be only remotely attended by Mission Control. Beginning with Apollo 14, extra LM propellant was made available for the powered descent and landing, by using the CSM engine to achieve the perilune.
During the mission Wisoff conducted a 5-hour, 50-minute spacewalk during which the EURECA communications antennas were manually positioned for latching, and various extravehicular activity tools and techniques were evaluated for use on future missions. STS-57 was accomplished in 155 orbits of the Earth in 239 hours and 45 minutes. STS-68 Endeavour (September 30 to October 11, 1994) was the Space Radar Lab-2 (SRL-2) mission. As part of NASA's Mission to Planet Earth, SRL-2 was the second flight of three advanced radars called SIR-C/X-SAR (Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar), and a carbon-monoxide pollution sensor, MAPS (Measurement of Air Pollution from Satellites).
Kounotori 8 was captured by the Space Station Remote Manipulator System (SSRMS) at 23:13 UTC, on 27 September 2019, and berthed at Harmony's nadir Common Berthing Mechanism (CBM) by 17:55 UTC, on 28 September 2019. The External Palette (EP8), which carries the lithium-ion battery Orbital Replacement Units (ORU), was extracted from the Kounotori 8's Unpressurized Logistics Carrier (ULC) by the SSRMS (Canadarm2) on 29 September 2019. The External Palette of Kounotori 7 (EP7) was placed in the Kounotori 8's ULC. . EP7 was left on the ISS after the departure of Kounotori 7 due to the schedule change of extravehicular activity after the launch failure of Soyuz MS-10.
Unlike colleague Wubbo Ockels—who withdrew from training to focus on Spacelab and remained an ESA payload specialist—Nicollier became a mission specialist, the first non-American to become a full-time NASA astronaut. Nicollier's technical assignments in the Astronaut Office have included flight software verification in the Shuttle Avionics Integration Laboratory (SAIL), participation in the development of retrieval techniques for the Tethered Satellite System (TSS), Remote Manipulator System (RMS), and International Space Station (ISS) robotics support. From the Spring of 1996 to the end of 1998, he was Head of the Astronaut Office Robotics Branch. From the year 2000 on, he was assigned to the Astronaut Office EVA (Extravehicular Activity) Branch, while maintaining a position as Lead ESA astronaut in Houston.
Additionally, human space travelers are often not well hydrated, have a 10-15% decrease in intravascular fluid (plasma) volume, and may lose both their preflight muscular and cardiovascular fitness levels as well as their thermoregulatory capabilities. As a result, they may become less heat- acclimated or may acquire an altered thermal sensitivity. Alterations in thermoregulation in association with spaceflight could significantly affect a variety of spaceflight-associated activities including exercise as a countermeasure to muscle atrophy, cardiac deconditioning, and bone loss; extravehicular activity (EVA); and vehicle landing and egress. EVA suits and launch and entry or advanced crew escape suits (ACES) worn by ISS and Shuttle crewmembers are designed to provide an impermeable barrier between the wearer and the external environment.
Illustration of the completed International Space Station with external workstations The Columbus External Payload Facility (Columbus-EPF) consists of two identical L-shaped consoles attached to the starboard cone of Columbus in the zenith (top) and nadir (bottom) positions, each supporting two platforms for external payloads or payload facilities. Four external payloads (payload facilities) can be operated at the same time. The first Columbus-EPF payload facilities were the European Technology Exposure Facility (EuTEF) and Sun Monitoring on the External Payload Facility of Columbus (Solar), which were installed during the STS-122/1E mission during an extravehicular activity (EVA) by crew members. Atomic Clock Ensemble in Space and EXPORT will be delivered to the International Space Station at a later, undetermined date.
Upon landing, the crew would put on their extravehicular activity (EVA) spacesuits and commence the first of five to seven lunar EVAs, collecting samples and deploying experiments. After completing their Lunar Sortie operations, the crew would then enter the Altair and fire the ascent stage engine to lift off from the surface, using the descent stage as a launchpad (and leaving it as a platform for future base construction). Upon entering orbit, the Altair would rendezvous and dock with the waiting Orion spacecraft, and the crew would then transfer, along with samples collected on the Moon, back to the Orion. After jettisoning the Altair, the crew would perform the Trans Earth Injection (TEI) burn for the return trip to Earth.
Mission STS-116: Curbeam participates in the mission's first session of extravehicular activity (EVA) as construction resumes on the International Space Station STS-85 (August 7–19, 1997) was a 12-day mission during which the crew deployed and retrieved the CRISTA-SPAS payload, operated the Japanese Manipulator Flight Demonstration (MFD) robotic arm, studied changes in the Earth's atmosphere and tested technology destined for use on the future International Space Station. The mission was accomplished in 189 Earth orbits, traveling 4.7 million miles in 284 hours and 27 minutes. STS-98 (February 7–20, 2001) continued the task of building and enhancing the International Space Station by delivering the U.S. laboratory module Destiny. The Shuttle spent seven days docked to the station while Destiny was attached.
The crew also conducted an unscheduled spacewalk to free the GRO high gain antenna, and conducted the first scheduled extravehicular activity in 5½ years to test concepts for moving about large space structures. Several middeck experiments and activities were conducted including test of elements of a heat pipe to study fluid transfer processed in microgravity environments (SHARE), a chemical processing apparatus to characterize the structure of biological materials (BIMDA), and an experiment to grow larger and more perfect protein crystals than can be grown on the ground (PCG II). Atlantis carried amateur radio equipment for voice contact, fast scan and slow scan TV, and packet radio. Several hundred contacts were made with amateur radio operators around the world. Mission duration was 143 hours, 32 minutes, 44 seconds.
At the same time, Foale became a member of the STS-86 crew and began moving his personal belongings back into Atlantis. Wolf will be replaced by the seventh and last U.S. astronaut to transfer to Mir, Andrew S. W. Thomas, when the orbiter Endeavour docks with the Russian space station during the STS-89 mission in January 1998. First joint U.S.-Russian extravehicular activity during a Shuttle mission, which was also the 39th in the Space Shuttle program, was conducted by Titov and Parazynski. During the five-hour, one- minute space walk on 1 October, the pair affixed a 121-pound () Solar Array Cap to the docking module for future use by Mir crew members to seal off the suspected leak in Spektr's hull.
Flight-Releasable Grapple Fixture The Flight-Releasable Grapple Fixture (FRGF) is the simplest variation of the North American grapple fixture, it allows only for grappling and does not have any electrical connectors. Its use began early in the Space Shuttle program and was developed from the Flight Standard Grapple Fixture (FSGF) by allowing the Grapple Shaft to be installed during extravehicular activity (EVA). Unpiloted ships like the SpaceX Dragon, Orbital ATK Cygnus and Japanese H-II Transfer Vehicle include a standard FRGF which is used by the Canadarm2 to grapple the capsule on approach to the International Space Station for berthing.Space station catches Dragon by the tail The fixture can have a maximum payload rating of 65,000 pounds or 30,000 kg.
Irwin and the Lunar Roving Vehicle during Apollo 15 Between July 26 and August 7, 1971 – as the Apollo 15 Lunar Module Pilot (LMP) – Irwin logged 295 hours and 11 minutes in space. His extravehicular activity (EVA) on the Moon's surface amounted to 18 hours and 35 minutes of the mission time (an additional 33 minutes was used to do a stand-up EVA by opening the LM's docking hatch to survey the surroundings and take photographs). Irwin and David Scott's mission was more science-based than previous missions, which meant that they received intensive geological training to meet the demanding nature of the J-Mission profile. This extra training is credited with allowing them to make one of the most important discoveries of the Apollo era, the Genesis Rock.
The Experimental Assembly of Structures in EVA and the Assembly Concept for Construction of Erectable Space Structures, or EASE/ACCESS, were a pair of space shuttle flight experiments that were performed on STS-61-B, on November 29 and December 1, 1985. The purpose of the experiments was to study how quickly astronauts would become proficient at assembling space structures during extravehicular activity, and how quickly they would become fatigued, and to explore various construction and maintenance techniques. In particular, researchers studied the applied moments of inertia arising in the manual assembly of a large space structure. EASE was a project of NASA's Marshall Space Flight Center and the Space Systems Laboratory at the Massachusetts Institute of Technology (later at the University of Maryland), while ACCESS was developed by NASA's Langley Research Center.
NASA therefore developed a model of the arm for use at its training facility within the Johnson Space Center located in Houston, Texas. The Canadarm can also retrieve, repair and deploy satellites, provide a mobile extension ladder for extravehicular activity crew members for work stations or foot restraints, and be used as an inspection aid to allow the flight crew members to view the orbiter's or payload's surfaces through a television camera on the Canadarm. The basic Canadarm configuration consists of a manipulator arm, a Canadarm display and control panel, including rotational and translational hand controllers at the orbiter aft flight deck flight crew station, and a manipulator controller interface unit that interfaces with the orbiter computer. One crew member operates the Canadarm from the aft flight deck control station, and a second crew member usually assists with television camera operations.
To simulate lunar surface gravity, weather balloons filled with helium were attached to the backs of the actors playing the astronauts in the lunar extravehicular activity scenes, effectively reducing their Earth-bound weights to one-sixth. The score of "Spider" prominently features an imitation of the main title theme from the 1963 World War II movie The Great Escape, and Tom Kelly jokes about having a crew digging a tunnel out of the Grumman plant. The episode also featured a real Apollo Lunar Module (LM-13), which had been built for the Apollo 18 mission but was never used due to budget cuts. Blythe Danner, who narrated the final episode, had previously worked on location at the Johnson Space Center for the 1976 movie Futureworld, filmed in the same buildings where Apollo moonwalkers had recently trained.
In addition, there are cardiopulmonary and vascular changes, including a significant decrease in red blood cell mass, that affect skeletal muscle function. This normal adaptive response to the microgravity environment is, for the most part, of little consequence within the space vehicle per se, but may become a liability resulting in increased risk of an inability or decreased efficiency in crewmember performance of physically demanding tasks during extravehicular activity (EVA) or abrupt transitions to environments of increased gravity (return to Earth, landing on the surface of another planetary body). In the U.S. human space program, the only in-flight countermeasure to skeletal muscle functional deficits that has been utilized thus far is physical exercise. In-flight exercise hardware and protocols have varied from mission to mission, somewhat dependent on mission duration and the volume of the spacecraft available for performing countermeasures.
Essential to the successful completion of the Apollo Program was the requirement for some crew members to undertake long and strenuous periods of extravehicular activity (EVA) on the lunar surface. There was concern about the capability of crew members to accomplish the lunar surface excursions planned for some of the Apollo missions. Although reduced lunar gravity was expected to make some tasks less strenuous, reduced suit mobility coupled with a complex and ambitious timeline led to the prediction that metabolic activity would exceed resulting levels for extended periods. Since the nature and magnitude of physiological dysfunction resulting from microgravity exposure had not yet been established (and is still not concisely defined), suitable physiological testing was completed within the constraints of the Apollo Program to determine if crewmember physiological responses to exercise were altered as a consequence of spaceflight.
Discovery (April 5–20, 2010), a resupply mission to the International Space Station, was launched at night from the Kennedy Space Center. Mastracchio pictured during an EVA with Clayton Anderson as part of STS-131 On arrival at the station, Discovery's crew dropped off more than 27,000 pounds of hardware, supplies and equipment, including a tank full of ammonia coolant, new crew sleeping quarters, and three experiment racks. As the EVA lead, Mastracchio performed three spacewalks during this mission and logged 20 hours and 17 minutes of extravehicular activity. On the return journey, the Leonardo Multi-Purpose Logistics Module inside Discovery's payload bay was packed with over 6,000 pounds of hardware, science results, and trash. The STS-131 mission was accomplished in 15 days, 02 hours, 47 minutes, 10 seconds, and traveled 6,232,235 statute miles in 238 orbits.
NASA planners invented the term extravehicular activity (abbreviated with the acronym EVA) in the early 1960s for the Apollo program to land men on the Moon, because the astronauts would leave the spacecraft to collect lunar material samples and deploy scientific experiments. To support this, and other Apollo objectives, the Gemini program was spun off to develop the capability for astronauts to work outside a two-man Earth orbiting spacecraft. However, the Soviet Union was fiercely competitive in holding the early lead it had gained in crewed spaceflight, so the Soviet Communist Party, led by Nikita Khrushchev, ordered the conversion of its single-pilot Vostok capsule into a two- or three-person craft named Voskhod, in order to compete with Gemini and Apollo. The Soviets were able to launch two Voskhod capsules before U.S. was able to launch its first crewed Gemini.
Astronaut Peter Wisoff on the end of shuttle robot arm, 1993 Selected by NASA in January 1990, Wisoff became an astronaut in July 1991. He is qualified for flight assignment as a mission specialist. His technical assignments to date include: spacecraft communicator (CAPCOM) in Mission Control; flight software verification in the Shuttle Avionics Integration Laboratory (SAIL); coordinating flight crew equipment; evaluating extravehicular activity (EVA) equipment and techniques for the construction of Space Station; lead for the Payloads and Habitability Branch of the Astronaut Office. A veteran of four space flights, STS-57 in 1993, STS-68 in 1994, STS-81 in 1997 and STS-92 in 2000, Wisoff has logged a total of 42 days, 56 hours, 1 minute and 48 seconds in space, including 19 hours and 53 minutes of EVA time in three space walks.
Feustel's subsequent NASA Astronaut training includes: Field Medical Training, Field Maintenance Training, NASA Extreme Environment Mission Operation (NEEMO) X in the Aquarius Habitat in Key Largo, Florida; CAVES in Sardinia, Italy; National Outdoor Leadership School training in Alaska and Mexico; Winter Survival Training with the Canadian Armed Forces; Desert RATS in Arizona; Geotechnical Studies in Antarctica; and DeepWorker Submersible Pilot Training. He is qualified as a Space Shuttle and Space Station Robotic Arm Operator, Capsule Communicator (CAPCOM), and Instructor Astronaut for Extravehicular activity (EVA) training at the Neutral Buoyancy Laboratory. In July 2006, Feustel served as an aquanaut during the NEEMO 10 mission aboard the Aquarius underwater laboratory, living and working underwater for seven days. In October 2006, Feustel was announced as a crew member for STS-125, the final Hubble servicing mission by the Space Shuttle.
SEATEST II, an acronym for Space Environment Analog for Testing EVA Systems and Training (number two), is a NASA underwater mission, formerly known as NEEMO XVII, in the Aquarius underwater laboratory in preparation for future space exploration. The objectives for this exercise are largely focused on the evolution of EVA (extravehicular activity) tools, and maturing some technologies that could have implications for the ISS and future exploration missions (MED and JITT delivery.) However, the SEATEST II mission will be very short, focused on engineering evaluations, and will not have time for the educational and public outreach that has been typical of NEEMO missions. The different name is a way of indicating a mission with somewhat different expectations than NEEMO missions have come to be known for. Before NEEMO 1, a short saturation mission was conducted to evaluate the Aquarius facility and capabilities.
Richard Gordon performs a spacewalk to attach a tether to the Agena Target Vehicle on Gemini 11, 1966 Based on studies to grow the Mercury spacecraft capabilities to long-duration flights, developing space rendezvous techniques, and precision Earth landing, Project Gemini was started as a two- man program in 1961 to overcome the Soviets' lead and to support the Apollo crewed lunar landing program, adding extravehicular activity (EVA) and rendezvous and docking to its objectives. The first crewed Gemini flight, Gemini 3, was flown by Gus Grissom and John Young on March 23, 1965. Nine missions followed in 1965 and 1966, demonstrating an endurance mission of nearly fourteen days, rendezvous, docking, and practical EVA, and gathering medical data on the effects of weightlessness on humans. Under the direction of Soviet Premier Nikita Khrushchev, the USSR competed with Gemini by converting their Vostok spacecraft into a two- or three-man Voskhod.
Ross during the first EVA; CGRO in the background NASA image STS37-051-021 Jay Apt on the first EVA of STS-37 with CGRO Jerry Ross and Jay Apt on the second EVA of STS-37, 8 April 1991 The first U.S. extravehicular activity (EVA) or spacewalk since 1985 was performed by Mission Specialists Jerry L. Ross and Jay Apt after six failed attempts to deploy the satellite's high-gain antenna. Repeated commands by ground controllers at the Payload Operations Control Center, Goddard Space Flight Center, Greenbelt, MD, and maneuvering of Atlantis and its Remote Manipulator System (RMS) robot arm, as well as CGRO's antenna dish, were to no avail in dislodging the boom. Ross and Apt were prepared for such a contingency, and Ross freed the antenna boom within 17 minutes after beginning the spacewalk. It was the first unscheduled contingency EVA since STS-51-D in April 1985.
SPARTAN-204 was later released from the arm to complete about 40 hours of free-flight, during which time its Far Ultraviolet Imaging Spectrograph instrument studied celestial targets in the interstellar medium, the gas and dust which fills the space between the stars and which is the material from which new stars and planets are formed. SPARTAN-204 was also used for extravehicular activity (EVA) near end of the flight. Foale and Harris began their EVA suspended at the end of the robot arm, away from the payload bay, to test modifications to their spacesuits to keep spacewalkers warmer in the extreme cold of space. The two astronauts were then scheduled to practice handling the approximately 2,500 pound () SPARTAN to rehearse space station assembly techniques, but both astronauts reported they were becoming very cold—this portion of the spacewalk being performed during a night pass—and mass handling was curtailed.
Apollo spacesuit worn by astronaut Buzz Aldrin on Apollo 11 Orlan space suit worn by astronaut Michael Fincke outside the International Space Station A space suit or spacesuit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. Space suits have been worn for such work in Earth orbit, on the surface of the Moon, and en route back to Earth from the Moon. Modern space suits augment the basic pressure garment with a complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum.
The training in geology included field trips to the Grand Canyon and Meteor Crater in Arizona, Philmont Scout Ranch in New Mexico, Horse Lava Tube System in Bend, Oregon, and the ash flow in the Marathon Uplift in Texas. There was also jungle survival training for the Fourteen in Panama, and desert survival training around Reno, Nevada. Water survival training was conducted at Naval Air Station Pensacola using the Dilbert Dunker. As the Mercury Seven and the Next Nine had done, each of the fourteen was given an individual area in which to develop expertise that could be shared with the others, and to provide astronaut input to designers and engineers: Aldrin was given mission planning; Anders, environment controls; Bassett, training and simulators; Bean, recovery systems; Cernan, spacecraft propulsion and the Agena; Chaffee, communications; Collins, pressure suits and extravehicular activity; Cunningham, non-flight experiments; Eisele, attitude controls; Freeman, boosters; Gordon, cockpit controls; Schweickart, in-flight experiments; Scott, guidance and navigation; and Williams, range operations and crew safety.
A reference to Christianity is also present in Le Guin's word to describe activity outside the ship: the real-world term "extravehicular activity" or EVA is used as a single word "Eva," in reference to the biblical "Eve": angels in the story see going outside the ship as an act of transgression associated with death. According to Payne, Le Guin does not explicitly criticize the concept of religion in general, but the tendency within religion to reduce "reality" to that which can be contained and controlled by the human mind. This "control" is only possible within the entirely human-made environment aboard the spacecraft, which Le Guin depicts as lacking elements of the "richly textured" real world, and which denies human beings the experiences of "wildness" which make life interesting. In Payne's view the story challenges the idea, common to Western society, that human beings, and technology, can solve all problems; it does so by presenting an entire planet as a system not amenable to control.
Apollo 9 was flown in March 1969. Schweickart spent just over 241 hours in space, and performed the first extravehicular activity (EVA) of the Apollo program, testing the portable life support system that was later used by the 12 astronauts who walked on the Moon. The flight plan called for him to demonstrate an emergency transfer from the lunar module to the command module (CM) using handrails on the LM, but he began to suffer from space adaptation syndrome on the first day in orbit, forcing the postponement of the EVA. Schweickart performs an EVA standing on the lunar module porch, photographed by fellow astronaut James McDivitt inside the LM. Eventually, he improved enough to perform a relatively brief EVA with his feet restrained on the LM "porch" (a platform used in transferring to the descent ladder), while Command Module Pilot Scott performed a stand-up EVA through the open hatch of the CM. During a five-minute pause tethered outside his spacecraft, Schweickart felt he underwent a metaphysical experience as he stared at the Earth, contemplating its place in the universe.
Dougherty must fly the untested Gemini spacecraft solo, achieve a rendezvous with the Mercury vessel stranded in orbit, get Pruett on board the new spacecraft in the empty co-pilot's seat, and return to earth. (At the time the novel was written, none of these tasks – Gemini launch, rendezvous or EVA – had even been attempted.) As NASA scrambles to prepare and launch the rescue mission, the Soviets secretly make their own plans to rescue Pruett first, rushing to send a cosmonaut aloft in a Vostok spacecraft. (In this version, the Soviets have already achieved the orbital objectives of rendezvous, docking and extravehicular activity [EVA]; in real life the Soviets did not achieve all these milestones until 1969.) Ultimately Dougherty succeeds in his mission and rescues Pruett; cosmonaut Andrei Yakovlev in the Vostok does rendezvous with the Mercury and provides assistance in the rescue (by using high-intensity spotlights to improve visibility) but does not take an active physical role in it. The novel ends with all three spacemen returning safely to Earth.
Fisher was selected as NASA Astronaut in 1980. His technical assignments included: scientific equipment operator for high altitude research on the WB-57F aircraft (1980–1981); astronaut medical support for the first four Shuttle missions (1980–1982); astronaut office representative for Extravehicular Mobility Unit (spacesuit) and Extravehicular Activity (EVA) procedures and development, including thermal vacuum testing of the suit (1981–1984); astronaut office representative for the Payload Assist Module (PAM-D) procedures and development (1982–1983); Astronaut office representative for Shuttle Mission Simulator (SMS) development (1983); support crewman for STS-8; CAPCOM for STS-8 and STS-9; Remote Manipulator System (RMS) hardware and software development team (1983); Manned Maneuvering Unit (MMU) development team (1983); Deputy Director of NASA Government-furnished and Contractor-furnished Equipment (1982–1983); Chief of Astronaut Public Appearances (1985–1987); Member of the U.S. Air Force Scientific Advisory Board (1986–1991); NASA Medicine Policy Board (1987–1991); Astronaut Office Space Station Manned Systems Division, and Health Maintenance Facility (1987–1989); Astronaut Office representative on space crew selection and retention standards for Space Station (1989–1991). Fisher also continued to practice Emergency Medicine in the greater Houston area in conjunction with his Astronaut duties. Fisher was a mission specialist on STS-51-I, which launched from Kennedy Space Center, Florida, on August 27, 1985.
