NASA and Astrobotic Investigating Ice Hunting Mission to the Moon

Posted by Unknown on from the repurposed-as-newt's-moon-scooter dept.

Zothecula writes, quoting Gizmodo "While the Moon may or may not contain life forms, precious metals or even green cheese, recent satellite missions have indicated that it does nonetheless contain something that could prove quite valuable — water ice. NASA has estimated that at least 650 million tons (600 million tonnes) of the stuff could be deposited in craters near the Moon's north pole alone. If mined, it could conceivably serve as a source of life support for future lunar bases, or it could be used to produce fuel for spacecraft stopping at a "lunar gas station." Before any mining can happen, however, we need to learn more about the ice. That's why NASA has contracted Pittsburgh-based Astrobotic Technology to determine if its Polaris rover robot could be used for ice prospecting."

      There's no point in building a heavy lift vehicle to build a lunar base that's going to use the water if we can't access the water. NASA is doing it right...It's a lot cheaper to send a robot to check out the water, see how easy it is to extract the water, and even return a sample to Earth than it is to send people there. And NASA would look really stupid if they get congress to fund a multi-billion dollar lunar base program only to discover that they don't have access to the water that they had counted on.

      There's no point in building a heavy lift vehicle to go to the moon in the first place.

      It's vastly easier to get from LEO to the moon and back than it is to get to LEO from the earth's surface. If NASA finds usable water on the moon that can be turned into propellant, then we should take that and bring it to LEO to use as a fueling station. Then when we want to go to the moon, we only need to lift the craft itself and not all the propellant that it will need to get from earth to the moon (which has an exponential effect on the size of rocket you need to get to orbit).

      What we need to start doing is treating space missions as two steps: 1) earth surface to earth orbit 2) earth orbit to wherever. And ideally stage 1) should never be lifting anything for stage 2) that doesn't need to come from earth.

      NASA is indeed doing it right. They know this is the way to do things in the future, and it's what they're trying to aim for.

      Of course then there's the Congress-mandated SLS pork rocket. Nice!

      650 millions tons is a lot when you consider that a lunar facility would be recycling most of the water, this gives a nice starting point without having to haul it out of our gravity well.

      I don't believe that NASA is planning on moving 6 billion people to the moon. 650 million tons of ice is plenty for a few hundred person colony or refueling station. Plus I doubt that they would be watering lawns, taking long bubble baths, or washing their cars. So if each person uses 90 tons of ice, and assuming no recycling, then: 650,000,000 tons of ice / 90 tons of eater per American per year = 7,222,222.222 years of water for one person for one year. One hundred people can live on the moon for 72,222 years or so.

      Once you have a significant amount of water and a refinery on orbit around the moon, this problem solves itself. You now have enough fuel to blast out to Ceres, which has more water ice on it than all the Earth's oceans and 0.03g surface gravity. Send a nuclear powered refinery out there the fast way with a big can. You don't even need to refine it at that point: you can blast all the way back with a steam powered rocket.
