4K Video: The launch of Crew 4 as seen from the press site

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Tuesday carrying the U.S. Air Force’s next GPS 3-series navigation satellite destined for an orbit more than 12,000 miles above Earth.

Strapped into a new SpaceX Crew Dragon capsule making its maiden flight, Whitson, test pilot Shubhanshu Shukla of India, European Space Agency astronaut Sławosz Uznański-Wiśniewski of Poland, and Hungarian engineer Tibor Kapu roared away from pad 39A at the Kennedy Space Center at 2:31 a.m. EDT.

The departure and return to Earth of a four-person space station crew on a SpaceX Dragon capsule has been postponed again by high winds in the splashdown zone in the Gulf of Mexico. NASA and SpaceX officials announced the Crew Dragon is now scheduled to undock from the International Space Station late Saturday for a predawn splashdown in the Gulf of Mexico early Sunday.
