NASA astronauts Doug Hurley, left, and Bob Behnken, seated at consoles inside SpaceX Mission Control in Hawthorne, California, monitor the Crew Dragon spacecraft static fire engine tests taking place at Cape Canaveral Air Force Station in Florida on Nov. 13, 2019. The tests will help validate the Crew Dragon’s launch escape system ahead of the upcoming in-flight abort demonstration as part of NASA’s Commercial Crew Program. Behnken and Hurley will be the first astronauts to fly aboard Crew Dragon in SpaceX’s Demo-2 mission to the International Space Station.
