NASA and SpaceX are closing in on the first launch of humans into orbit from US soil since 2011, when the space shuttle made its final flight.

Although the space agency has not yet said so publicly, NASA is working toward a May 7 launch of a Crew Dragon spacecraft carrying astronauts Doug Hurley and Bob Behnken to the International Space Station.

Asked Monday about the early May launch date, the director of Johnson Space Center, Mark Geyer, said it is tentative and that no final decisions have been made. The International Space Station and Commercial Crew programs are continuing to consult with NASA Administrator Jim Bridenstine and the agency’s chief of human spaceflight, Doug Loverro. “That’s the target the two programs have agreed is reasonable, but we’re still confirming with Jim and Doug really when we think we’re going to launch,” he said.
