Ax-3 is still in its early stages at the moment. The private space company must still submit four proposed crew members and two backup crew members for review to the agency, with the mission commander being a flown NASA astronaut. (For example, retired NASA astronaut Peggy Annette Whitson led Ax-2.) NASA may request that the commander perform particular tasks or scientific experiments while onboard, according to the parties’ agreement. Meanwhile, Axiom Space astronauts will have access to NASA cargo and other in-flight resources on a daily basis.
