Cool Pics: SpaceX’s Dragon in Prep for First ISS Flight

Some cool images courtesy of SpaceX. Above, technicians prepare the Dragon spacecraft for thermal vacuum chamber testing in a SpaceX clean room shown above in Hawthorne (Los Angeles) California. The open bays will hold the parachutes. NASA has given SpaceX a launch date of Nov 30, 2011 for Falcon 9 Flight 3, which will send a Dragon spacecraft to the International Space Station (ISS) as part of NASA’s Commercial Orbital Transportation Services program.

Also in Hawthorne, we have conducted separation tests of the Dragon trunk from the Falcon 9 second stage (shown above). Release mechanisms hold the trunk (top), with solar panel covers on left and right sides) to the stage (bottom). When activated, springs on the Falcon 9 push against the Dragon trunk. The trunk separates and the test fixture’s counterbalance system raises the spacecraft up and away.


In the Hawthorne factory high bay, we tested the Dragon solar array rotary actuator by hanging the full array from the ceiling. The actuator (top center) turns the entire array. In flight, the solar panels will track the sun for maximum energy capture.

We are well into production with all parts (shown above) for the following launch, Falcon 9 Flight 4 and its Dragon CRS-1 spacecraft, which should be the first commercial cargo resupply mission under NASA Commercial Resupply Services (CRS) program.  Significant additional tooling and automation with be added to the factory, as we build towards the capability of producing a Falcon 9 first stage or Falcon Heavy side booster every week and an upper stage every two weeks.  Depending on demand, Dragon production is planned for a rate of one every six to eight weeks.

This week, we successfully completed a wet dress rehearsal (WDR) for the Falcon 9 Flight 3 launch vehicle at Space Launch Complex 40, Cape Canaveral, Florida.  The WDR is a significant test during which we load propellant into the vehicle and perform all operations just as we would on launch day right down to T-1 seconds, at which point we abort and detank the propellant.


Demolition work continues at Space Launch Complex 4 East, our new launch site at Vandenberg Air Force Base on the central coast of California. Recently, the crew dropped the big “hammerhead” overhanging structure from the legacy Titan IV Mobile Service Tower (sequence above). Removing the tower is a major step in upgrading the pad for Falcon 9 and Falcon Heavy launches. We are targeting late 2012 to bring Falcon Heavy to Vandenberg for vehicle to pad integration tests and 2013 for liftoff.  Falcon Heavy will be the most powerful rocket in the world.
