Photos: Delta 4 launches on secret NROL-45 mission

A Russian Soyuz rocket launched from French Guiana on Thursday at 1154:53 GMT (7:54:53 a.m. EDT) with the SES 15 communications satellite, a U.S.-built craft designed to support in-flight connectivity, video broadcasts and airborne navigation over North America.

After completing a dress rehearsal for launch day over the weekend, the four astronauts gearing up for liftoff Thursday on a SpaceX Falcon 9 rocket are in good spirits and spending time with their families in Florida before leaving the planet for a six-month expedition on the International Space Station. Forecasters with the U.S. Space Force’s 45th Weather Squadron predict an 80% chance of acceptable weather for launch early Thursday.

SpaceX launched 57 Starlink broadband satellites and a pair of Earth observation smallsats for BlackSky on top of a Falcon 9 rocket at 1:12 a.m. EDT (0512 GMT) Friday. The 90th launch of a Falcon 9 rocket took off from pad 39A at NASA’s Kennedy Space Center in Florida.
