NASA has unveiled its plan to construct the first lunar railway system, designed to offer reliable, autonomous, and efficient payload transport on the Moon. In its official blog, NASA said that this durable, long-lasting robotic transport system will be essential for the daily operations of a sustainable lunar base envisioned for the 2030s, as part of NASA’s Moon to Mars initiative and mission concepts like the Robotic Lunar Surface Operations 2 (RLSO2). Moreover, NASA has proposed a solution for transporting regolith mined for ISRU consumables (H2O, LOX, LH2) or construction materials, as well as for moving payloads around the lunar base and to/from landing zones or other outposts. They introduce FLOAT — Flexible Levitation on a Track — to address these transportation needs.
