Psyche Spacecraft Headed for Xenon Fueling

NASA’s Psyche spacecraft took another step closer on its upcoming journey to a metal-rich asteroid of the same name. On Aug. 14, a team of technicians and engineers moved the spacecraft from Building 1 to Building 9 at Astrotech Space Operations facility near the agency’s Kennedy Space Center in Florida. Inside Building 9, technicians will load about one metric ton of xenon gas into seven 22-gallon tanks inside the spacecraft.

Psyche’s solar electric propulsion will use large solar arrays to convert sunlight into electricity, which will power four Hall thrusters. The thrusters will use electric and magnetic fields to accelerate and expel charged xenon particles, or ions, to create thrust and propel the spacecraft to its destination after launch. The thrusters will operate one at a time and will have a blue glow from the xenon.

Psyche is targeted to launch Oct. 5 atop a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy. After launch, Psyche is set to arrive at the asteroid in July 2029, where it will spend 26 months gathering observations that will help scientists learn more about planetary formation.

In addition to its primary mission, Psyche has NASA’s Deep Space Optical Communications (DSOC) technology demonstration onboard the spacecraft. DSOC will be the agency’s first demonstration of optical communication beyond the Moon. DSOC will send test data to and from Earth using an invisible near-infrared laser, which has much higher bandwidth than radio wave systems currently used on spacecraft.
