Novel strategy proposed for massive water production on the moon
Water plays a crucial role in human survival on the lunar surface, thus attracting extensive research attention. Prof. Wang Junqiang's team at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has recently developed a new method of massive water production through a reaction between lunar regolith and endogenous hydrogen.
Research results of previous lunar explorations, like the Apollo and Chang'E-5 missions, have revealed the widespread presence of water on the moon. However, the water content in lunar minerals is extremely low, ranging from 0.0001% to 0.02%. It remains challenging to extract and utilize water in situ on the moon.
"We used lunar regolith samples brought back by the Chang'E-5 mission in our study, trying to find a way to produce water on the moon," said Wang.
Lessons from industry can inform satellite and spacecraft management in orbit
Most space mission systems historically have used one spacecraft designed to complete an entire mission independently. Whether it was a weather satellite or a human-crewed module like Apollo, nearly every spacecraft was deployed and performed its one-off mission completely on its own.
But today, space industry organizations are exploring missions with many satellites working together. For example, SpaceX's Starlink constellations include thousands of satellites. And new spacecraft could soon have the capability to link up or engage with other satellites in orbit for repairs or refueling.
Some of these spacecraft are already operating and serving customers, such as Northrop Grumman's mission extension vehicle. This orbiting craft has extended the lives of multiple communications satellites.
