Waiter, there's metal in my moon....

There is a significant amount of water on the moon, and this discovery has shocked various scientists. Like we have been learning, the moon has taken some heavy hits from various asteroids. So, it is hard for the scientists to understand the amount of water the moon holds. But, this is not just pure water, it is water that contains metals, and most recently discovered, sodium. This moon water contains a significant amount of sodium, which is interesting because they do not know exactly where it all originated from. Scientists at NASA believe that it could have come from comets, and then was trapped in the frozen water. "The team plans to shed light on the origin of lunar water and other volatiles using data from the upcoming Lunar Atmosphere and Dust Environment Explorer (LADEE) mission, scheduled to be launched in May, 2013". This mission is another stepping stone (like I have said in the past) in learning more about our universe, which I think is important.

Despite the contamination of the lunar water with metals and sodium, could this be a possibility for life on the Moon? Also, this could mean that comets are a way of transporting water (since they are icy) to other planets, spreading the possibility of life.

Even though there was water found on the moon, I still don't think there could be life found there at all. Yes, water is vital for any sort of life to appear and survive, but the water found on the moon was both contaminated with sodium and metals as well as being frozen solid. Comets weren't what was transporting water, they contained sodium, and when the comets crashed into the moon, the sodium was released and instead trapped into the water on the moon.

While it does seem likely that these metals came from comets, it would also be good to examine other possible sources. I wonder if this has made scientists question our giant impact theory for the formation of the moon.

Earlier in the semester didn't we discuss that it is probably that much of Earth's water also came from comets? If so, and we have seen water come from comets to both Earth and the Moon, then we have seen the replication of a water-acquiring process on two planetary bodies. Therefore, I think we can assume that such a process could occur in other solar systems as well, further evidence of life beyond our own solar system.

water has to be collected from comets on terrestrial bodies
they form in regions that are too hot for water to freeze into ice, so the only way for them to contain water was for a comet to bring it once the body has cooled
as for the possibility of life on the moon, i don't think it's possible because of the lack of any atmosphere and the lack of the ability to hold onto gases......life as we know it at least
