When I first heard that NASA was going to have a big announcement today I got excited. Surely, the news had to be that alien life was discovered on the Far Side of the Moon! But sadly the news wasn’t about aliens. Despite what Giorgio Tsoukalos will have you believe it’s never aliens. But not all hope is lost. The announcement that was made, that lunar soil contains water, is actually quite exciting in its own right.
According to NASA’s press release:
“NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.
SOFIA has detected water molecules (H2O) in Clavius Crater, one of the largest craters visible from Earth, located in the Moon’s southern hemisphere. Previous observations of the Moon’s surface detected some form of hydrogen, but were unable to distinguish between water and its close chemical relative, hydroxyl (OH). Data from this location reveal water in concentrations of 100 to 412 parts per million – roughly equivalent to a 12-ounce bottle of water – trapped in a cubic meter of soil spread across the lunar surface. The results are published in the latest issue of Nature Astronomy.
“We had indications that H2O – the familiar water we know – might be present on the sunlit side of the Moon,” said Paul Hertz, director of the Astrophysics Division in the Science Mission Directorate at NASA Headquarters in Washington. “Now we know it is there. This discovery challenges our understanding of the lunar surface and raises intriguing questions about resources relevant for deep space exploration.”
As a comparison, the Sahara desert has 100 times the amount of water than what SOFIA detected in the lunar soil. Despite the small amounts, the discovery raises new questions about how water is created and how it persists on the harsh, airless lunar surface.
Water is a precious resource in deep space and a key ingredient of life as we know it. Whether the water SOFIA found is easily accessible for use as a resource remains to be determined. Under NASA’s Artemis program, the agency is eager to learn all it can about the presence of water on the Moon in advance of sending the first woman and next man to the lunar surface in 2024 and establishing a sustainable human presence there by the end of the decade.”
Thinking even beyond 2024, this discovery could have profound implications for the future of space travel as well. Because if water is more prevalent throughout the Universe than we thought, lurking not just on Earth like planets or on Asteroids but on the surfaces of moons as well, then we have infinitely more options for where we can travel to and for how long. Of course an announcement about aliens would have been better. But I’ll settle for water on the Moon any time.
