People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Doubt cast on evidence for wet Moon

RATE THIS! +22
Posted in Science on 24th Mar, 2014 11:43 PM by AlexMuller

Scientists have cast doubt on a major part of the case for the Moon having once held abundant water. A US team studied a mineral called apatite, which is found in a variety of lunar rock types. Apatite, whose name comes from a Greek word meaning deceit, may have misled scientists into thinking the Moon is wetter that it actually is.

 
Lead author Jeremy Boyce said: "We thought we had a great indicator, but it turns out it's not that reliable." Initial analysis of the lunar rocks brought back to Earth by the Apollo missions, suggested the Moon was "bone dry".
 
But in the last decade, studies of volcanic glasses and apatite in lunar rocks have revealed them to be hydrogen-rich, building a compelling case for significant water having been present on the Moon as different minerals crystallised from the cooling magma.

Presence of water on the moon was regarded as important - water is a potential source of fuel that could provide energy for colonisation - now this option is gone. Reply

Several previous reports supported presence of water in samples returned to Earth by the robotic Luna 24 spacecraft and also in in beads of volcanic glass from Apollo samples. Clearly, researchers did their best at the time. But that's the progress of science - there are course corrections

It is not the presence of water but the abundance that needs to be debated. Definitely, there is still water on the Moon. Those rocks are not completely anhydrous. But the abundances, we've demonstrated, are difficult to interpret. Reply

I think that the ambition about the moon will remain. On the surface, the Moon looks like one big lump of moon dust. Many scientists believe that below that surface, there exist deposits of water, rare minerals, and other substances not so common here on Earth.

This is not just about the moon and space. Simply knowing how plants deal with stress on the moon can tell us a lot about how they deal with stress here on Earth Reply

This NASA teaming up with students and private space companies is great. Lets hope they will grow the first plants on the moon’s surface from 2015. Reply
