Q&A with Elon Musk after SpaceX’s first rocket landing

A SpaceX Falcon 9 rocket soared into orbit Monday from Cape Canaveral with nearly three tons of hardware and supplies for the International Space Station.

The four astronauts preparing to ride SpaceX’s Crew Dragon “Resilience” into orbit climbed aboard their spaceship Thursday at the Kennedy Space Center in a practice run for a launch to the International Space Station planned Saturday night, while mission managers monitored weather and sea conditions in recovery areas across the Atlantic Ocean.

A commercial cargo capsule owned by SpaceX concluded a month-long resupply trip to the International Space Station on Saturday, wrapping up the 13th round-trip flight to the station by a Dragon spacecraft with an on-target splashdown in the Pacific Ocean west of Baja California.
