SpaceX CRS-2 Falcon 9 CEIT

CAPE CANAVERAL, Fla. -- NASA astronaut Megan McArthur, center, takes part in a crew equipment interface test CEIT in order to become familiar with the Space Exploration Technologies Corp. SpaceX Dragon capsule prior to its scheduled April 30 liftoff. The interface test inside a processing hangar at Cape Canaveral Air Force Station's Space Launch Complex-40 was part of prelaunch preparations for the company's next demonstration test flight for NASA's Commercial Orbital Transportation Services COTS program. Under COTS, NASA has partnered with two private companies to launch cargo safely to the International Space Station. United Space Alliance technicians, Dan Nelson, left, and Chris Hardcastle, right, show McArthur two power connectors that are similar to the ones astronauts will use to provide power to Dragon once at the station. CEIT is an activity that dates back to NASA's Space Shuttle Program, providing astronauts on Earth an opportunity to work with the actual hardware they would use in space. This exercise gave astronauts and engineers the opportunity to assess the compatibility of the equipment and systems aboard Dragon with the procedures to be used by the flight crew and flight controllers once the capsule is berthed at the space station.
