The spacecraft will launch in August 2022 and travel about 1.5 billion miles (2.4 billion kilometers) over three and a half years to get to the asteroid, which scientists believe may be part of the core of a planetesimal, the building block of an early rocky planet. The orbiter’s target: a metal-rich asteroid also called Psyche. Once the stuff of science fiction, the efficient and quiet power of electric propulsion will provide the force that propels the Psyche spacecraft all the way to the main asteroid belt between Mars and Jupiter. When it comes time for NASA’s Psyche spacecraft to power itself through deep space, it’ll be more brain than brawn that does the work.

One of the thrusters is visible on the side of the spacecraft underneath a red protective cover.
Engineers at NASA’s Jet Propulsion Laboratory work to integrate Hall thrusters into the agency’s Psyche spacecraft in July 2021.
