CAPE CANAVERAL, Fla. – If there is any hesitation from the crew about the dangerous adventure of SpaceX’s Crew-1 mission, it is well hidden.

The astronauts’ quartet – three from NASA and called NASA Crew-1 from Japan – is optimistic and friendly. They have a motto, they are like a merry-go-round: “One for all, Crew-1 for all.”

If their launch, scheduled for 7:27 tonight, is a success, it could be another coup by the space agency.

The crew-1 crew is NASA’s best roll call:
