NASA just Sent Out a tiny spacecraft to Scope out an Orbiting Moon Base

A rocket expected to blast off Tuesday morning from New Zealand will tread a unique path around the moon where the U.S. agency would like to put an orbiting space station. Called Gateway, this base would serve as a place for Artemis astronauts to live and prepare for trips back and forth to the moon’s surface.

The mission to establish the space-flying outpost could become a reality in as little as two years. Picture the base as something akin to the International Space Station: a place for people to live, with several ports for docking spacecraft, and a lab for conducting space weather experiments.

Rocket Lab, a commercial rocket company, will launch NASA’s test mission, the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, aka CAPSTONE, with live coverage beginning at 5 a.m. ET/9:00 UTC and takeoff at 5:55 a.m. ET Tuesday. Then, about one week after launch, the public can track its whereabouts using NASA’s Eyes on the Solar System tool.

No astronauts will ride along this time. Instead, Rocket Lab will send a 55-pound microwave oven-size satellite on one of its light-lift Electron rockets, which the company says is the smallest rocket to ever attempt a launch to the moon. The satellite will become the first spacecraft to ever fly in a so-called “near rectilinear halo orbit” around the moon. This path should have special gravitational properties — tugs from Earth and the moon to create a nearly stable orbit — and ensure the moon base is continuously facing Earth, allowing uninterrupted communication.

Scientists examined many potential orbits before determining this one was the best fit for a base. A low-lunar orbit, for example, would circle very close to the moon’s surface. That would put the base closer to the ground but would require a lot more fuel to counteract the moon’s gravity, according to NASA. A distant retrograde orbit, on the other hand, would be more stable and require less fuel but would be less convenient for accessing the ground.
