The launch was set to take place today, but has been tentatively pushed to May 30.

The historic launch set for Wednesday, May 27, was going to send Americans back into space after nearly a decade, but it has now been canceled "due to weather conditions."

The SpaceX Crew Dragon space shuttle was planning on launching from Kennedy Space Center in Florida, with NASA astronauts Douglas Hurley and Robert Behnken.

The launch will be rescheduled for 3:22 p.m. ET on Saturday, May 30.
