Material Properties of Regolith and Other Materials Available on the Moon, Mars and Asteroids

Watch Philip Metzger from University of Central Florida giving a talk "Material Properties of Regolith and Other Materials Available on the Moon, Mars and Asteroids for 3D Additive Construction" on August 24, 2015 at Caltech. This talk was part of the Short Course "Using In-Situ Resources for 3D Additive Construction in Space" presented by the Keck Institute for Space Studies.

I’ve been looking for some real information, thanks. I just subscribed.

great information about available material on the lunar surface. I am not into the obsession with robots and materials to be returned to earth. much more interesting is the potential to go to the moon and produce equipment to explore the rest of the solar system. how do we humans get to go? not so much robots as humans.

Great talk, but I don't like this hype-train over-emphasis on 3D printing. It's a good tool for a lot of things, but not a magic wand. I'm glad to hear people are still working on these refinement processes and I'd love to hear more details on it! How long could a molten iron electrolysis vessel possibly last? What would it be made of? Could you just melt in an open pit with heliostats?

There is a bad issue with your AV setup when a NASA engineer can't figure it out.
