(Merritt Island, FL) – A native Iowan and three colleagues will have to wait a bit longer to get into space. This (Wednesday) morning’s SpaceX Falcon 9 Ax-4 mission to the International Space Station (ISS) was supposed to lift off at 7-a.m. from NASA’s Kennedy Space Center in Florida, but officials announced late Tuesday that the delay was necessary, to repair liquid oxygen leak identified during post static fire booster inspections.

The launch, originally scheduled for Sunday morning and again Tuesday morning, had been delayed both until Wednesday, due to the weather in Florida.

The mission, with Iowa native Peggy Whitson in command, was not immediately rescheduled. It will be her fifth mission when it finally takes off.
