Watch our interview with two International Space Station astronauts

SpaceX launched 60 more Starlink internet relay platforms into orbit Sunday as the company ramps up network testing in Washington state and touts a streak of nearly 300 satellites launched since June without a spacecraft failure.

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.

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.
