Similar to how SpaceX broadcast video of a spacesuit-clad “Starman” in a Tesla roadster launched by its Falcon Heavy rocket last year, there will be cameras inside the Crew Dragon capsule. “It will give you a perspective that you would have if you were inside,” said Hans Koenigsmann, SpaceX’s vice president for build and flight reliability.

SpaceX has faced scrutiny for decisions like planning for the crew to be onboard while the rocket is fueled. In the past, NASA has considered that too risky, but SpaceX prefers to use supercooled liquid oxygen and kerosene, which are more efficient but cannot remain at those temperatures for very long. Fueling begins just 35 minutes before liftoff.

The space agency has tentatively approved SpaceX’s approach, known as “load and go.” “We came to the conclusion that this was an acceptable risk that we were willing to take,” said Patrick G. Forrester, chief of NASA’s astronaut office.

Other issues still to be resolved before a crewed flight include certification of the parachutes and fixing a design issue with the thrusters where pieces can break off if they get too cold.

Russia, the main partner on the International Space Station, also raised concerns that the Crew Dragon did not have a backup system to steer the capsule away if the main computer were to fail. But on Thursday, NASA officials said they had managed to allay those worries by adding precautionary measures.

If there are additional delays, NASA may buy more Soyuz seats from the Russians.

When the Obama administration announced the beginnings of the commercial crew program in 2009, NASA already had plans to develop a much more expensive rocket, the Ares I, as part of a project to send astronauts back to the moon. But the NASA rockets, and the moon program, were canceled.
