  • SpaceX Dragon V2 launch pad abort test (ZOOMMMM!!)

    There will be Dragon Fire on NASA TV

    The DragonV2 test vehicle will launch from a truss structure at KSC Launch Complex 40 after a simulated Falcon 9 abort signal is initiated. Its eight 3D printed SuperDraco thrusters will generate almost 16,000 lbf of thrust each, pulling Dragon V2 and its finned Trunk to safety going supersonic in <5 seconds.

    The Trunk fins add stability through the abort burn, then after the SuperDracos shut down the Trunk separates and Dragon V2's parachutes open for a water touchdown offshore.

    If this test goes well, this Dragon V2 will demonstrate its reusability by being used in a mid-launch abort test at Space Launch Complex 4E at Vandenberg Air Force Base later this summer.

    MEDIA ADVISORY M15-062

    Media Accreditation Opens for SpaceX Commercial Crew Pad Abort Test

    Media accreditation is open for a pad abort test of SpaceXs Crew Dragon spacecraft next month. The test will simulate an emergency abort from a test stand on Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

    SpaceX's Crew Dragon spacecraft is prepared for critical pad abort test that will take place at NASA's Kennedy Space Center, Florida, in May.

    As a development test, the likelihood of encountering an issue is higher than with operational missions. SpaceX currently is targeting no earlier than Tuesday, May 5, for the test flight. The company will have a four-hour window to conduct the test, beginning at about 9:30 a.m. EDT. SpaceX has an additional test opportunity on May 6.

    NASA Television will provide live coverage of the test. NASA TV also will air a media briefing previewing the test with SpaceX and NASA representatives. The date and time for the briefing, which will take place at NASA Kennedy Space Centers Press Site, are yet to be determined.

    The ability to abort from a launch or pad emergency and safely carry crew members out of harm's way is a critical element for NASA's next generation of crew spacecraft. SpaceX will perform the test under its Commercial Crew Integrated Capability (CCiCap) agreement with NASA, but can use the data gathered during the development flight as it continues on the path to certification. Under a separate Commercial Crew Transportation Capability (CCtCap) contract, NASA's Commercial Crew Program will certify SpaceXs Crew Dragon, Falcon 9 rocket, ground and mission operations systems to fly crews to and from the International Space Station.

    Highlights,

    NASA webcast begins ~25mins before opening of window.

    Objective: to show that astronauts can be flown to safety. It's a development test and they will learn even if it's not fully successful.

    Test date: May 6
    Launch window: 0700-1430 Eastern.

    SpaceX may tweak the time for wind conditions. Wind is the main test constraint, and the main reason for doing the test early AM before the winds build.

    Test setup: a truss over the LC-40 flame duct topped with an upper stage simulator, Dragon 2 and its Trunk. Lightning tower inner wires will be removed for clearance.

    Launch mass: 9,525.44 kg (21,000 lbs)
    Propellant load: 1,587.57 kg (3,500 lbs)
    No Control Panel
    Test dummy name: Buster (Mythbusters fans?)
    Mass simulators for other crewmembers.

    Flight profile: 6 second burn, 20 second coast to apogee (1,524 m, 5,000 ft), Trunk separation then parachutes deploy. 90 seconds total.

    G load: estimated 4.5 G's (this test)
    Velocity: 180 m/sec (400+ mph)

    This is the first time all 8 SuperDraco's have been fired simultaneously. So far only 2 at a time in tests. Synchronization is key.

    Nominal landing distance is about 1,830 m (6,000 ft) from the pad. Shoreline is about 915 m (3,000 ft), so Dragon should land about 915 m (3,000 ft) from shore.

    After splashdown, Dragon will go to Texas for decontamination and inspection. Local post-recovery ops will be done on the recovery barge.

    This Dragon will be reflown for the in-flight abort test at Vandenberg AFB SLC-4E. Flight abort at MaxQ, about 13,000 m (40,000 ft.)

        5 THINGS TO KNOW ABOUT SPACEX’S PAD ABORT TEST

        Crew Dragon's first critical flight test, known as a Pad Abort Test, is expected to take place this Wednesday, May 6, from SpaceX’s Space Launch Complex 40 (SLC-40) in Cape Canaveral, Florida. While the test is originating from the same launch pad we use for operational missions, this is not an operational flight.

        This will be the first flight test of SpaceX’s revolutionary new launch abort system, and the odds of encountering delays or issues are high. Fortunately the test doesn’t need to be perfect to be valuable—our primary objective is to capture as much data as possible as the data captured here will be key in preparing Crew Dragon for its first human missions in 2017.

              SpaceX Adjusts Test Window

              SpaceX reported this evening that its Pad Abort Test window will open at 9 a.m., rather than 7 a.m. Media buses will depart the press site promptly at 7:30 for the ITL Causeway.

              NASA will provide updates about the test on the Commercial Crew Blog and air the test live on NASA Television 25 minutes prior to T-0.

                      No date on the flight abort yet, but late summer is the rumor.

                      Elon chatted with reporters. One SD underperformed a bit, but she still flew nicely for a first test,

                      @AstroGingerSnap Amy Lynn
                      @elonmusk does not yet have the numbers yet, but says capsule went 0-100 mph in 1.2 seconds. Definitely faster than Telsa. #LaunchAmerica

                      @elonmusk says that all 8 SuperDracos do not have to fire to abort, a minimum of 4 do. #LaunchAmerica #SpaceX

                      #SpaceX confirms that the #Dragon test vehicle's top speed was 345 mph. #LaunchAmerica

                      Next big tests for #SpaceX will be the in-flight abort and the first uncrewed flight to @Space_Station. #LaunchAmerica
                      @BadAstronomer
                      #SpaceX #Dragon test: One SuperDraco was very slightly below nominal thrust. Unclear how this affected performance.
                      @jeff_foust Jeff Foust
                      Musk said one SuperDraco thruster had a slightly off mixture ratio, but that did not materially affect the flight."

                          Florida Today update....

                          Update, noon: SpaceX CEO Elon Musk called today's Dragon pad abort test from Cape Canaveral "a great outcome."

                          Data from the test remains to be analyzed, but Musk said all eight of the Dragon's SuperDraco engines fired properly.

                          "Had there been people on board, they would have been in great shape," Musk told reporters on a teleconference. "So I think it was very exciting."

                          "I think this bodes quite well for the future of the program," he said. "I don't want to jinx it, but certainly this is really quite a good indication for the future of Dragon."
