A little while ago, SpaceX’s Crew Dragon Endeavour spacecraft docked with the International Space Station’s Harmony module completing the first part of its private Axiom Mission 1 or simply Ax-1 mission that began with its launch yesterday. After they verify that the pressure has been correctly balanced, the hatch will be opened to allow Michael López-Alegría, Larry Connor, Eytan Stibbe, and Mark Pathy to enter the Station.
