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

SpaceX launched two Falcon 9 rockets in a span of a little more than four hours Friday, a record-setting day that began with the launch of 52 Starlink internet satellites from California and ended with the sunset liftoff of two SES television broadcast payloads from Florida.

A Falcon 9 rocket blasted off into a brilliant morning sky over the Sunshine State on Wednesday, and these photos show the kerosene-fueled launcher climbing away from Cape Canaveral’s Complex 40 launch pad.

The development mission includes fewer additional mission milestones compared to the third flight with a focus on demonstrating the reusability model that Starship promises. Liftoff happened at 7:50 a.m. CDT (8:50 a.m. EDT, 1250 UTC), near the opening of a 120-minute window.
