A few hours ago, the SPHEREx space telescope and the PUNCH satellites, two NASA astronomy missions, blasted off atop a SpaceX Falcon 9 rocket from the Vandenberg base. After about 42 minutes, SPHEREx successfully separated from the rocket’s last stage, and about 10 minutes later, the PUNCH satellites also separated, within about a minute. Both missions will operate from a Sun-synchronous orbit at an altitude of 700 kilometers for SPHEREx and 570 kilometers for PUNCH.
