Polyethylene homes on the moon

High density polyethylene is being used by scientists at the Los Alamos National Laboratory in New Mexico to create shelters on the moon, according to this article from UPI.

Scientists from Prairie View A&M University's Center for Radiation Engineering and Science for Space Exploration (CRESSE) created simulated moon dirt by analysing samples brought back from previous moon missions, and combined it with HDPE to create shelters that provide protection against radioactivity.

Ideally they would like to make lunar shelters from materials already on the moon.

"It would take $1 million a pound to bring things to the moon," CRESSE research scientist Brad Gersey said of the NASA-funded research. "We need to use something that's there already."
