While the Sun seems like a solid friend to Earth and its inhabitants right now, what with its steady stream of life-nourishing solar radiation and illuminating sunshine, that setup is only temporary, and our planet is pretty much on loan.
|
|
Some researchers argue the lack of diversity affects both which geoengineering projects get discussed—whether Spice-style solar radiation management, spreading glass beads over Arctic ice, or iron fertilization of oceans, to name a few—and how their risks get calculated.

According to NASA, the spacecraft is protected from solar radiation by a 4.5-inch-thick carbon-composite shield, which despite weighing just 160 pounds should allow onboard instruments to operate at room temperature even during the most intense parts of its journey.
|
|
A new study in *Nature *by Lowell Observatory astronomer Will Grundy suggests a mixture of those long, frigid winters, the gases escaping Pluto's atmosphere, and solar radiation could create the moon's most unusual feature—the large, dark red area covering its north pole.
|
|
Of course, even the two months estimate is more of an educated guess; even assuming a perfect launch, there are a lot of variables that could still impact things, from solar radiation to balloon inflation direction to unforeseen drag to communication issues.
|
|
Their results showed a tiny amount of water molecules migrating around the Moon based on the temperature, where the rocks release the most water around noon when the temperature is highest and the water moves to areas with less incoming solar radiation.
|
|
But if the space agency pulls this off — and shows the habitat can protect against extreme temperatures, solar radiation, and space debris — it's possible that these expandable habitats will one day be used to usher in an era of private space hotels.
|
|
While it is known that solar radiation management can cool the atmosphere, fears that field research would look too much like deployment have so far limited research pretty much to computer modeling of its effects and small-scale experiments in the lab.

To survive the intense solar radiation and searing heat near Mercury, mission leads armed Mariner 21975 with thermal blankets, sunshade cloth, and special heat-resistant paint, plus they allowed it to shift its solar panels into partial shade to prevent them from frying.
|
|
But in the Holocene, the period beginning at the end of the last ice age, some 203,220 years ago, scientists made an unexpected observation: minimal solar radiation in the summer, as is currently the case, without any signs of an impending ice age.
|
|
A storm associated with the push of Arctic air deposited a fresh snowpack across the Great Lakes region on Monday, and this increases the chances of record cold readings since snow-covered ground is more efficient at reflecting solar radiation back into the atmosphere.
|
|
"It is assumed that something comes out from [the] interior of the planet where there is a large amount of water and that can evaporate filling the crater and eventually dispersed under the action of solar radiation," the team said in a press release.
|
|
The Harvard researchers point out that the acceleration of 'Oumuamua can be explained by pressure from Solar radiation, and that it could be powered by a light sail, a type of solar propulsion technology that, conveniently, one of those scientists is researching at Harvard.
|
|
The instrument was born as an intent to characterize the planet's environment beyond weather -- including variables like temperature, pressure and wind -- and gain a better understanding of solar radiation on the surface, according to Manuel de la Torre Juarez, deputy principle investigator for MEDA.
|

Carbon dioxide and the greenhouse effect Carbon dioxide is called a "greenhouse gas" because of its ability to trap solar radiation in the Earth's atmosphere like a blanket and heat up the planet -- acting the same way a greenhouse keeps plants warm and growing.
|
|
As they worked to "crack the code of glacial inception," attempting to explain when and under what conditions the planet enters into an ice age, they found that anthropogenic emissions, not only levels of solar radiation, have now become a permanent variable in that equation.
|
|
Given the 120 years or so we've got and the amount of distance Bennu has left to travel before its nearby approach, if scientists could make some of it more susceptible to the solar radiation, that would slightly alter its path enough that it would miss us.
|
|
For example, peak deployment of solar panels was shown to happen in areas with a population density of 1,000 people per square mile, and 4.5 kWh/m2/day appeared to be the threshold for incoming sunlight (solar radiation), above which solar deployment was practically a given.

It will include a field test phase in which scientists will spray tiny, highly reflective particles at altitudes of greater than 153 miles above the Arizona desert, in order to test the efficacy of one of the most widely-known geoengineering methods, called solar radiation management.
|
|
A fresh snowpack, courtesy of a storm moving through the region earlier in the week, will enhance the potential for record cold readings, as snow-covered ground is more efficient at reflecting solar radiation back into the atmosphere during the day and keeping it colder at night.

Scientists looking into ways to artificially cool the planet as a possible fix to global warming â€" a plan referred to as geoengineering â€" are considering mimicking the cooling mechanism from volcanoes by injecting tiny particles into the upper atmosphere, which would reflect incoming solar radiation.
|
|
The best modern guess is that the Chronicle's writers were looking at an unusually powerful manifestation of the northern lights, and that the high 14C levels are a consequence of this isotope being generated abundantly in the atmosphere by elevated levels of solar radiation, which also stimulated the auroras.
|
|
"Sea ice has a great ability to reflect a lot of solar radiation back into space... we still have some sea ice (but) to say that it is where it used to be is saying you can serve a cup of tea in a broken cup," he said.
|
|
"From the point of view of climate economics, solar radiation management is still a much worse solution than greenhouse gas emissions: more costly and much more risky over the long run," said Philippe Thalmann of the École Polytechnique Fédérale de Lausanne, an expert in the economics of climate change.

NASA has been planning to have an astronaut enter the expandable habitat periodically throughout the two-year mission to run a battery of tests on how the structure fares against solar radiation and extreme fluctuations in temperature — just some of the conditions that can affect astronauts in long-duration space travel.
|
|
And that means you also have to account for a whole planet's worth of data: temperature and pressure readings and wind-speed metrics, from as many places as you can manage, along with various annoying, fiddly things—like water vapor and solar radiation, or the presence of valleys and mountains.
