SpaceX founder and CEO Elon Musk speaks with NASA administrator Jim Bridenstine, along with astronauts Victor Glover, Doug Hurley, Bob Behnken and Mike Hopkins, in front of the company's Crew Dragon capsule.

Elon Musk expects his space company's inaugural launch of NASA astronauts is only a few months away.

The SpaceX CEO said on Sunday that the company's first crewed mission will probably be in the second quarter of this year, between the months of April and June. Known as Demo-2, this mission would see two NASA astronauts visit the International Space Station for at least a few days. Musk noted that the rocket and spacecraft needed for the mission are already coming together in Florida.

"We're highly confident the hardware will be ready in Q1, most likely in February but no later than March," Musk said.

Musk made the comments at a press conference after the company completed the in-flight abort test of its Crew Dragon capsule. Musk spoke alongside NASA Administrator Jim Bridenstine, who added that the agency and SpaceX are considering making Demo-2 a longer mission than previously expected.

"If it's going to be a longer duration, then we have to have some additional training for our astronauts to actually be prepared to do things on the International Space Station that we weren't planning to have that initial test crew necessarily do. So we've got to look at that and make a determination," Bridenstine said.
