Kennedy Space Center - America’s gateway to the universe SpaceX preps for 2014 abort test By Rebecca Regan Spaceport News n preparation for a summer I2014 test, NASA partner Space Exploration Technolo- gies (SpaceX) recently laid out its plan to demonstrate the Dragon spacecraft’s ability to carry astronauts to safety in the event of an in-flight emer- gency. This review of the in-flight abort test plan provided an assessment of the Dragon’s SuperDraco engines, the soft- ware that would issue the abort command, and the interface between the Dragon and the Falcon 9 rocket on which the spacecraft will be launched. “It’s critical to have a launch abort system in which NASA and SpaceX can have confi- dence,” said Phil McAlister, director of Commercial Space- flight Development at NASA Headquarters in Washington, D.C. The in-flight abort test will take place along Florida’s Space Coast. During the test, a Dragon spacecraft will launch on a standard Falcon 9 rocket and an abort command will Photo courtesy of SpaceX SpaceX displays its launch abort test Dragon capsule in September at its headquarters in Hawthorne, Calif., in preparations for its sched- uled in-flight abort test which will take place along Florida’s Space Coast in Summer 2014.

In September, a meteorological airship containing a “Cloud Lab” flew over Ken- nedy’s Shuttle Landing Facility carrying components of NASA’s Microorganisms in the Stratosphere (MIST) experiment. According to principal investigator David J. Smith, a microbiologist in Kennedy’s Engineering and Technology directorate, MIST has two goals. One is to collect microorganisms at high alti- tudes. The other is to intentionally expose microorganisms to the atmosphere to understand how they survive while aloft.
