SpaceX Revs Its Engines as It Gets Closer to Crewed Flight

Wired 1/28/2019 by Amy Thompson

Last Thursday, a shiny new SpaceX Falcon 9 rocket sat perched atop NASA’s historic Pad 39A, at Florida’s Kennedy Space Center, waiting to briefly fire its engines. The exercise was part of a routine prelaunch test. What wasn’t routine was the presence of a Crew Dragon capsule atop the slick black-and-white Falcon. The domed capsule, which can accommodate up to seven passengers, represents the next big step in SpaceX’s evolution and in NASA’s dependency on a commercial space industry.

As the rocket’s nine Merlin engines roared to life for a few seconds, exhaust plumes billowed around the launchpad. The test simulated all of the events of an actual launch, though with the rocket secured to the pad. A static test fire typically occurs one to two weeks before a scheduled take-off. Although just a practice run, it is getting extra scrutiny because it signals the impending return of crewed space launches to American soil. And it means new hardware: the launch pad features a black-and-white astronaut walkway, called a crew access arm, which was installed last summer. A few hours after the test fire, SpaceX tweeted that it was a success.
