Now just a year and a half from launch, the mission to explore a metal-rich asteroid will soon begin assembling and testing the spacecraft.
NASA’s Psyche mission has passed a critical milestone that moves it a step closer to launch. After an intense review of the mission’s progress in building its science instruments and engineering systems, Psyche won clearance to progress into what NASA calls Phase D of its life cycle – the final phase of operations prior to its scheduled launch in August 2022.
Until now, the mission has focused on planning, designing, and building the body of the spacecraft, its solar-electric propulsion system, the three science instruments, electronics, the power subsystem, and the like. The successful review of those elements means the mission can now begin delivering components to NASA’s Jet Propulsion Laboratory, which manages the mission and will test, assemble, and integrate each piece.
“It’s really the final phase, when all of the puzzle pieces are coming together and we’re getting on the rocket. This is the most intense part of everything that happens on the ground,” said Arizona State University’s Lindy Elkins-Tanton, who as principal investigator for Psyche leads the mission.
Psyche’s target is an intriguing, ...
