Good luck
@Astro_Christina and@Astro_Jessica. A lot of people work behind the scenes to support NASA missions like these (@NASAFltDirector, controllers, engineers). Without them, missions like these are not possible. Thanks to everyone supporting, especially at@NASA_Johnson.https://twitter.com/NASA/status/1219205608865509378 …Thanks.

Exciting weekend! Had fun dry-running
@SpaceX Crew Dragon pre-launch activities--w/space suits & modern transport. Saw first hand demo of Dragon's launch escape system. Two very different types of excitement (check our faces)! Super proud of what the team has accomplished!pic.twitter.com/ppHWm3ymDJ
