In the YouTube version of the video, SpaceX explains that the test was performed on November 24 last year, the second part of two tests conducted at SpaceX’s facility in McGregor, Texas, arranged to satisfy NASA’s Commercial Crew Program requirements:
Eight SuperDraco thrusters, positioned around the perimeter of the vehicle in pairs called “jet packs”, fired up simultaneously to raise the Crew Dragon spacecraft for a five-second hover, generating approximately 33,000 lbs of thrust before returning the vehicle to its resting position. This test was the second of a two-part milestone under NASA’s Commercial Crew Program. The first test—a short firing of the engines intended to verify a healthy propulsion system—was completed November 22, and the longer burn two-days later demonstrated vehicle control while hovering.
As for when people will get a chance to ride this thing, that could come as early as next year.
NASA recently revealed a crew of four astronauts that will be the first to ride in a private craft, and placed an order for a human-crewed flight to the International Space Station for 2017, but the agency still hasn’t said which private company will begin flights.
SpaceX and Boeing are the two leading contenders, Boeing with its lesser-known CST-100 Starliner capsule. Earlier this week, NASA published a great overview of what both companies hope to accomplish in space travel throughout 2016 and 2017, and it says very clearly that there are three Dragon 2 flights planned, though when precisely these will take place is not specified. As NASA puts it:
Three Crew Dragon spacecraft are in different stages of production at SpaceX’s headquarters and factory in Hawthorne, California. Two will perform upcoming flight tests to the International Space Station, one without a crew and one with astronauts aboard. The first of these spacecraft will be refurbished after flight for an in-flight abort test that will be conducted from Florida’s Space Coast, while the third will fly the operational crew mission to the station by SpaceX.
But there are also indications that the ambitious timeline for such a test flight could get delayed until 2018 or later.
Additionally, the initial human-crewed tests of the Dragon 2 won’t rely on the SuperDraco thrusters, but rather more traditional parachute-guided descents into the ocean, according to NASA.
Still, SpaceX is clearly getting things ready for its first unmanned tests of the Dragon 2, as well as the eventual human-crewed missions. That’s exciting in-and-of itself, no matter how far-off the end goal might be. Even creating a craft capable of performing a controlled hover test like this is no easy feat — it is, after all, rocket science.
