NASA, Boeing, and ULA (United Launch Alliance) are forgoing a Crew Flight Test launch attempt Sunday, June 2, to give the team additional time to assess a ground support equipment issue at Cape Canaveral Space Force Station’s Space Launch Complex-41 in Florida.

Saturday’s launch to carry NASA astronauts Butch Wilmore and Suni Williams to the International Space Station scrubbed due to an observation of a ground launch sequencer. The system was unsuccessful in verifying the sequencer’s necessary redundancy.

ULA will assess the ground support equipment overnight, and NASA will provide an update June 2 on next steps for the flight. The next available launch opportunities are Wednesday, June 5, and Thursday, June 6.
