NASA’s Psyche spacecraft flew by Mars on May 15, using the planet’s gravity to gain speed and slightly tilt its trajectory. The flyby also gave the team an opportunity to prep for the science they will be conducting when they reach the metal-rich asteroid Psyche in 2029.
Using Mars as a stand-in for the asteroid during the flyby, they could test the spacecraft’s science instruments. The results, downlinked and analyzed over the subsequent weeks, were impressive. Not only did the instruments operate precisely as designed, delivering data that matches what NASA already knows about Mars, they also provided a few new insights about the planet along the way.
