Commercial Crew

These photos show the 215-foot-tall Falcon 9 rocket and Crew Dragon spacecraft on pad 39A at the Kennedy Space Center, ready for launch on a test flight to the International Space Station with NASA astronauts Doug Hurley and Bob Behnken when weather cooperates.

Mission managers are weighing a motley mix of weather models, safety criteria and astronaut workload considerations as they decide when SpaceX’s Crew Dragon spacecraft might have the best chance to launch from the Kennedy Space Center.

Stormy weather across Florida’s Space Coast forced SpaceX to call off the long-awaited launch of two astronauts aboard the company’s Crew Dragon spacecraft, the first piloted flight to orbit from U.S. soil in nearly nine years.

SpaceX’s Falcon 9 rocket and Crew Dragon spacecraft were lowered horizontal on pad 39A at NASA’s Kennedy Space Center the day before launch, allowing teams to address an issue with a chilled water loop near the top of the strongback structure.
