NASA's Moon Melting Plan for Mars Building.

NASA's Moon to Mars Planetary Autonomous Construction Technology (MMPACT) team is preparing for the first construction projects on a planetary body beyond Earth. The team is planning to use regolith, the Moon's surface material, to build sustainable, long-lasting structures. The first step toward 3D printing on the Moon will involve using lasers or microwaves to melt regolith, which will then be printed into desired shapes. The team is also developing synthetic versions of lunar regolith to experiment with. The MMPACT team's first off-planet project is tentatively scheduled for late 2027.
