As NASA prepares to send astronauts back to the moon, the spaced agency is funding a series of research and development (R&D) projects focused on turning lunar regolith into landing pads, blast shields and other useful structures.

NASA recently selected four R&D projects for funding under its Small Business Technology Transfer (STTR)  program. The projects, which partner small businesses with academia, will each receive up to $150,000 apiece for studies lasting 13 months.
