Scientists develop lunar bricks as first steps in lunar construction

lunar_construction.jpg A team of Virginia Tech students, under the advisement of Kathryn Logan, a professor in the materials science and engineering department, designed a lunar brick as a potential building tool for future colonies on the moon. The invention recently won the In-Situ Lunar Resource Utilization materials and construction category award from the Pacific International Space Center for Exploration Systems (PISCES). The award was one of two prizes given out this year by the research center, which is dedicated to supporting life on the moon and beyond. They found that it was almost as strong as concrete under various pressure tests. This strength would enable it to withstand an environment where gravity is a fraction of the pull on Earth. The more than yearlong ongoing research has included studying the bricks reaction to solar radiation and their effectiveness as a construction material for lunar applications.

Since actual lunar rock, known as regolith, is scarce, the students used volcanic ash from a deposit on Earth along with various minerals and basaltic glass, similar to rock on the lunar surface.
