Launching from Vandenberg Air Force Base on California’s Central Coast on its third try, United Launch Alliance’s Delta 2 rocket lifted off Saturday with NOAA’s JPSS 1 polar-orbiting weather satellite.

NASA’s nuclear-powered Perseverance rover is set to arrive at Mars on Thursday with a make-or-break entry, descent, and landing. The rover will execute the arrival autonomously, while engineers and scientists back on Earth will have a nail-biting 11-minute wait for signals to reach home confirming the fate of the $2.7 billion mission.

SpaceX’s Falcon 9 rocket rolled out to its launch pad at Vandenberg Air Force Base, California, on Monday, one day before its scheduled liftoff carrying seven satellites into orbit on commercial communications and climate research missions.
