Researchers with the U.S. Naval Research Laboratory (NRL), to whom NASA provided the lunar samples for a research study, announced last week that they discovered hydrogen in lunar soil sample 79221. The detected hydrogen is thought to have been brought into existence by incessant showers of solar wind, and even comet strikes, on the moon.
Per one NASA estimate, it would cost thousands of dollars to launch a bottle of water to the moon. So to cut costs, ice on the moon can be used in-situ as water for astronauts — and, in fact, may also be broken down into its components (hydrogen and oxygen) to be used as rocket fuel for journeys between the moon and Earth. Perhaps it can be used to bring humans to Mars as well someday; perhaps beyond.
In 2020, data from SOFIA, a now-retired, flying infrared telescope, showed that water on the moon may be sprinkled as ice across its surface, rather than in pools limited to permanently shadowed regions near the north and south lunar poles.
Interestingly, Apollo astronauts had collected lunar rocks not from near the south pole of the moon, where many countries hope to establish long-term presence, but from near its equator. Thus, the new findings "have important implications for the stability and persistence of molecular hydrogen in regions beyond the lunar poles," scientists write in the new study.
India's Chandrayaan-3 moon mission, which deposited a now-dormant robotic lander-rover duo near the lunar south pole, revealed another intriguing element on the surface — sulfur, and perhaps in higher amounts than previously thought. This element may one day help astronauts develop storage batteries and other infrastructure on the moon.
