NASA and SpaceX held a joint training event for pre-launch operations, which provided an opportunity for the crew and ground operators to rehearse all of the activities, procedures, and communication the teams will exercise on launch day from crew suit-up in Kennedy Space Centers Operations & Checkout (O&C) building in Florida through launch; this training event also included simulated emergency egress scenarios. NASA astronauts Bob Behnken, left, and Doug Hurley are participating in a suit-up for launch, using the same Ground Support Equipment hardware, such as the seats and suit leak check boxes, that the crew will use for launch, with the SpaceX ground closeout team and suit engineers that will help the crew suit up and ingress the Dragon on launch day. Following crew suit-up, the crew ingressed the capsule simulator in Hawthorne, California, as they would on launch day, and the teams performed a simulated launch countdown and several emergency egress scenarios.
