Not long ago, scientists assumed that the I Need Water And Food To Survive I Need Yarn To Live Shirt, Hoodie, Tank top, Sweater moon was completely dry. Then, in 2009, a trio of papers reported spectral evidence of OH bonds in sunny areas, although the researchers were unable to tell whether they belonged to water or to hydroxyl substituents. on other molecules. In 2018, scientists reported ice in shaded craters.

The 2009 results are based on an IR signal of almost 3 m because that’s what spacecraft use can measure. Water has a clear IR signal at 6 µm.
Scientists previously thought that solar radiation would destroy water molecules or push them to colder regions. Based on the new data, the team calculated that the surface of the moon is 100-400 parts per million water. But Hannibal stresses that the moon is still a very dry place: its surface can be about 100 times drier than the sand in the Sahara.
The water they observe is notice or liquid; it exists as single molecules. Researchers do not know whether these molecules are trapped inside glass formed by asteroid collisions or trapped between lunar dust particles. Hannibal said it is planning for further observations that may fix that. Water can be carried to the moon on meteors, formed during asteroid effects, or came from within the moon.
The team signed up for more trips on SOFIA to try to map most of the near side of the moon at different times. That could reveal more about the location and source of water molecules and also show how water moves around the lunar surface. “They deserve more time” to answer these questions, Sunshine said.
A new study led by NASA scientists has uncovered water present on the lunar surface in places previously thought impossible, raising new potentials to exploit valuable resources in manned mission by the end of the decade.
Research published this week found water on sunny parts of the lunar surface, rejecting the longstanding theory that water cannot survive lunar days. It opens up the possibility that water can be more easily harvested and plentiful, giving future missions to the moon the ability to access water from areas other than the icy layer on the dark and icy poles of the face. moon.
The landmark research has now been hypothesized by NASA scientists about exactly how water may exist on the I Need Water And Food To Survive I Need Yarn To Live Shirt, Hoodie, Tank top, Sweater surface of the moon and how much water is present. It is also unclear to what extent humans can access water for drinking, turn it into oxygen or exploit it as a source of fuel.
“This discovery raises new questions about how water was created and how it could survive,” Paul Hertz, director of NASA’s Astrophysics Division, said at a press conference on Monday. in extreme conditions, there is no atmosphere on the sunny surface of the Moon ”.
Casey Honniball, the lead author of the study, said scientists had known for years about the presence of hydrogen in sunlight parts of the moon, but measurements were too inaccurate to determine that. is water, or hydroxyl, a similar molecule. But researchers were able to use a powerful infrared telescope called SOFIA, or the stratosphere Observatory for infrared astronomy, to observe the lunar surface at the right wavelength for testing. Chemical fingerprint checking is only available in the water.
“This observation eventually allowed us to ascertain that water molecules are present on the I Need Water And Food To Survive I Need Yarn To Live Shirt, Hoodie, Tank top, Sweater sunlit surface of the moon,” said Hannibal.
Water is measured at concentrations between 100 and 400 parts per million – hardly a puddle, Hannibal said, but enough to fill a 12-ounce bottle of water from a cubic meter of lunar soil.
Observations are limited because they can only detect water on the very surface of the moon, and it is not known if the water could be buried several meters underground.
