Snapshots from Atlas 5 launch

The mission featured the launch of NASA’s largest spacecraft bound on a planetary mission. Liftoff from Launch Complex 39A happened 12:06 p.m. EDT (1606 UTC).

The astronaut “is in stable condition under observation as a precautionary measure,” NASA said in a statement 10 hours after the Crew Dragon’s landing. “To protect the crew member’s medical privacy, specific details on the individual’s condition or identity will not be shared.”

Former space shuttle commander Bob Cabana, who has led NASA’s Kennedy Space Center since 2008, will take a new job in Washington as the space agency’s No. 3 official next week.
