NASA’s Big Moon Surprise Is That Lunar Soil Contains Water – Futurism

It’s an “exciting new discovery” that NASA has been hyping up for since last week.

Water has been confirmed for the first time on the sunlit surface of the Moon — not just in the form of ice limited to the shadowed surfaces of larger craters as previously thought.

In other words, even when exposed by the warming radiation from the Sun, water is capable of surviving there. It’s a tantalizing result, and one that could have huge implications for human settlement of the natural satellite, but plenty of questions remain: we still don’t know if the water is accessible to use as a resource.

A pair of papers published by the journal Nature detail the discovery, which was made using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA).

Using SOFIA, the team identified liquid water’s unique fingerprint near the southern pole of the Moon. It’s not there as “puddles of water,” as Casey Honniball, postdoctoral fellow at NASA’s Goddard Space Flight Center and lead author of one of the studies, described during a live stream, but spread out molecules of H2O.

It’s also not an awful lot of water: about 12 liquid ounces in a cubic meter of soil. It might also be quite tricky to extract as it’s completely mixed in with the soil.

The scientists suggest the water could have come through either the solar winds, or from impacting micrometeorites that may have contained water on their own.

The second paper found that the Moon is dotted with “billions” of tiny craters, creating shadowed regions all over its surface. The researchers concluded that these regions are technically cold enough to hold frozen ice.

These mini craters would also be far easier to access by astronauts. That means the discovery has major impacts on NASA’s plans to send astronauts to the surface of the Moon as soon as 2024 and establish a permanent human presence by the end of the decade.

“If we find that it’s abundant enough in certain locations, it would be easier to access versus going into these very cold, very dark places,” Honniball told The Verge.

In addition, water wouldn’t need to be brought there as payload on rockets, a highly expensive process.

SOFIA, a collaboration between NASA and the German Aerospace Center, is at its core a massive telescope mounted to the inside of a gutted 747 jumbo jet. A large door cut into the side of the body of the plane allows an 8.2 foot diameter telescope to make infrared observations at altitudes of over 40,000 feet — well above the atmosphere’s obscuring water vapor.

SOFIA hunts for a number of different celestial events, including the birth and death of stars, the formation of new solar systems, and the identification of complex molecules in space.

NASA had to ground SOFIA in mid-March due to the ongoing coronavirus pandemic, with flights resuming only in early June. The project even faced existential threats to its funding when no funding was allocated for SOFIA in NASA’s fiscal year 2021 budget proposal.
