For those who dream of building a base on the moon, a major engineering challenge is figuring out how to move rovers, ice, and other cargo across treacherous terrain and out of steep, jagged lunar craters. Caltech students are behind a project called LATTICE (for Lunar Architecture for Tree Traversal in-service-of Cable Exploration). The LATTICE team is designing a self-deploying modular robotic system for transporting ice and other assets in and out of those craters. The system, which would wor
