Q&A with Sara Seager, deputy director of science on NASA’s TESS mission (members only)

Watch a video replay of Thursday’s liftoff of a SpaceX Falcon 9 rocket from pad 39A at NASA’s Kennedy Space Center in Florida, carrying the Es’hail 2 communications satellite into orbit.

SpaceX’s Falcon 9 rocket lifted off Sunday from Vandenberg Air Force Base in California and carried 10 Iridium communications satellites toward a perch in low Earth orbit, then the launcher’s first stage nailed a landing on a platform positioned in the Pacific Ocean.

A Falcon 9 rocket and 60 more Starlink internet satellites set for launch early Sunday at Cape Canaveral will mark the first time SpaceX has flown a first stage 10 times, reaching a milestone that the company once said could be a limit for reusing boosters. Now SpaceX plans to keep flying reused rockets on Starlink missions until one fails.
