Moon may have frozen water in south pole crater, study says

If humanity ever colonizes the moon, we'll need the help of local resources, like water and solar power. The lunar poles, which contain regions of constant sunlight, as well as constant darkness, could be ideal locations for finding both.

Scientists have exciting new insights about the south pole in particular: A study released in Nature today suggests that there is frozen water within a massive, well-preserved crater there.

The Shackleton crater is more than 12 miles in diameter and about two miles deep, and exists in permanent shadow. While the evidence for ice in the crater has been inconsistent, this new study, conducted by scientists at Massachusetts Institute of Technology, Brown University and NASA's Goddard Space Flight Center, finds evidence for ice on the floor of the crater.

The research team, led by Maria Zuber of MIT's Department of Earth, Atmospheric and Planetary Sciences, used an instrument called a laser altimeter aboard NASA's Lunar Reconnaissance Orbiter (LRO) to create a highly detailed topographical map of Shackleton crater. The laser basically lit up the area, allowing the team to measure the natural reflectivity (albedo) of the crater's interior, which Zuber describes as "extremely rugged."

Those measurements revealed that the crater's floor is much brighter than the floor of other nearby craters, which is consistent with ice in the area. Ice may make up 22% of the first micron-thick layer of the crater's floor, which Zuber says is about 100 gallons - not too much. However, these measurements aren't at all indicative of what ice may be beneath the surface.

The researchers also observed that the crater's walls were brighter than the floor - a surprise, given that the thinking was that if ice present were inside Shackleton, it'd be on the floor, since there's even less sunlight reaching the bottom of the crater than its walls.

Zuber and her team explain the brighter walls by theorizing that occasional "moonquakes" might cause older, darker soil on Shackleton's walls to slide off, revealing brighter soil underneath.

LRO orbits the moon from pole to pole, which allows the laser altimeter to map a different slice of the moon with each orbit. Each slice contains data from both lunar poles. Zuber and her team ultimately used over 5 million measurements of Shackleton crater to create their map, which is unprecedented in its level of detail and helpful for studying crater formation and other lunar processes. Detailed maps like these are also useful for planning future robotic or human missions.

One of those future missions is NASA's Gravity Recovery and Interior Laboratory (GRAIL) spacecraft, also in orbit around the Moon. "We'll be attempting to detect evidence for subsurface ice this fall," says Zuber.

    Yes, there are a lot of chipmunks this year. Not sure exlcaty why, but they tend to go through boom bust cycles, as to many small mammals. Perhaps the deep layer of snow was good insulation to allow more to survive the winter, perhaps abundant fall food allowed for good caches for the winter. There might be a corresponding bumper crop of some raptors.

    Considering they found ice on the side of the moon not visible from earth back in 1996, which was confirmed to be water by satellite, this isn't really much of a discovery.

    Aren't these BOGUS searches for water by NASA so convenient?

    Just when NASA has a big budget cut and has to cancel its water-finding MARS missions, it suddenly "uncovers" water on the MOON.

    Living on the moon a few months at a time would be cool. In others words an OK place to visit but I wouldn't want to live there. With surface temperatures around 150 Fahrenheit at moon noon and -150 before dawn a stroll around the rim of the crater would always be dangerous not to mention you have to carry your own air.

    There's no point in exploring the resources on moons and planets for the sake of terraforming and making them habitable. We can't even manage to terraform and save Planet Earth. If we don't force the fossil fuel companies to retool for clean energy, Earth is going to look like the moon in a century.

      That is comical that you think humans have the power to impact the earth to the point where we are going to cause CATASTROPHIC changes in 100 years. The earth was here long before humans and will be here long after as well. Forces of nature are far more powerful than anything humans can do.

        That's not true, we do impact the Earth on a daily basis. If you think that we can not change the behaviors of the atmosphere then set off a few Tzar bombs. As to the disagreements between the eco-friendly people and the people who don't believe in climate change, it seems that they are too extreme in either case. It's not all going to blow up tomorrow as the movie "Day after Tomorrow" would have you believe. It's not entirely impossible, but quite improbable. The thought that we don't affect the environment around us is just close minded. For every action, there is an equal and opposite reaction.

        It is NOT ridiculous that human activities, taken en masse, could significantly alter the planet. Furthermore, since there are only certain conditions in which the planet is even habitable for us, we might not need to significantly alter it. We only need to alter it in such a way as to make *our* lives on this planet precarious.

        What he is saying is that we can't create CATASTROPHIC changes in 100 years, if we get close to doing that the Earth will wipe us out and go back to the way it was before.

        I would have imagined that making the planet uninhabitable for humans counts as a catastrophic change. Even making populated *portions* of the planet uninhabitable would count. But maybe thats just me.

      There's no reason we can't do both. America managed to spend over several thousand billion dollars (a couple of trillion) on the wars in Iraq and Afghanistan. What has that accomplished? Had we spent that on clean energy research and space exploration, there still would have been a large sum left over. Money is not really the problem–it's allocating resources to what is most in the national interest.

    If Newt gets the VP job, maybe he can still go ahead with 13,000 people on the moon. They will need water in the size of several Olympic sized swimming pools to be able to grow food, drink and to have their own gym and sports club. They will also need water to wash their pimped out moon buggies and to make slushies at the moon based convience stores.

    These findings are not recent at all. I remember my astronomy professor talking about this three years ago. He explained that if in fact this is frozen water it does not imply that it is being produced by the moon but simply generated by the atmosphere. So because of the atmosphere water molecules may have caused the concentration of what resulted in frozen water.

      Popeye, I thought the same thing when I was a kid in the early sixties. I am 56 now and I still hope I live to see at least a manned trip to Mars. Maybe it's just me, but I feel we lost a small sense of purpose in this country when we did not keep going to the Moon, and beyond. I know folks always say we can do this after we eliminate hunger, poverty, etc. As Jesus said, the Poor will always be with us. In the meantime I think it's important to feed the spirit with continuing exploration of the Solar System, at least.
