The four tourists aboard Inspiration4 have every hour planned over the next three days in space.
They'll have time to talk to their families — using NASA's TDRS communications system —and will also be conducting experiments.
Hayley Arceneaux, for example, will also talk to her patients at St. Jude, where she works as a physician assistant.
The crew will also be able to check out their surroundings through a big dome window called the Copula — the same name they gave to the viewing window on the International Space Station. They all will have plenty of time to take in views of the Earth and cosmos.
The living quarters: The Dragon Capsule, called Resilience, has been used on one other mission. It is 13-feet wide.
The last mission it flew was SpaceX's Crew-1 mission, which ferried four astronauts to the ISS.
