While NASA eyes a planned launch of its first big Artemis moon mission early Wednesday, a tiny cubesat has officially arrived at the moon to serve as a pathfinder for upcoming stages of the agency’s lunar program.
Capstone, short for the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, is the size of a microwave oven and designed to circle the moon via an eccentric elliptical orbit (formally known as a near rectilinear halo orbit) that’s never been flown by a spacecraft before.
Capstone is checking out the route in advance of NASA’s plans to build a space station dubbed Gateway to ply the same orbit. The Gateway will be a waypoint for astronauts in the Artemis program, designed to get humans back on the moon, and it will house equipment and supplies for trips to the lunar surface.
