The SpaceX main parachutes control the descent of the Dragon test article
following a drop test over the Pacific Ocean, off the coast of Morro Bay, Calif.
Engineers and safety specialists from NASA and Space Exploration Technologies
(SpaceX) gathered in Morro Bay, Calif., in late December to demonstrate how the
company's Dragon spacecraft's parachute system would function in the event of an
emergency on the launch pad or during ascent.
The test was part of an optional milestone under NASA's Commercial Crew
Integrated Capability (CCiCap) initiative and approved by the agency in August.
Through the Commercial Crew Program, SpaceX is one of NASA's commercial partners
working to develop a new generation of U.S. spacecraft and rockets capable of
transporting humans to and from low-Earth orbit from American soil. NASA intends
to use such commercial systems to fly U.S. astronauts to and from the
International Space Station.
The 12,000-pound test craft was lifted 8,000 feet above sea level by an
Erickson Sky Crane helicopter and flown over the Pacific Ocean. Following
Dragon's release, two drogue parachutes were released from the top of the
spacecraft to slow its decent, before the three main parachutes deployed. The
craft splashed down and was quickly recovered by the Sky Crane and carried back
to shore.
"The parachute test is essential for the commercial crew effort because it
helps us better understand how SpaceX's system performs as it safely returns
crew," said Jon Cowart, NASA Partner Integration deputy manager working with
SpaceX. "Like all of our partners, SpaceX continues to provide innovative
solutions based on NASA's lessons learned that could make spaceflight
safer."
During a normal spacecraft landing, the parachutes will be aided by the
Dragon’s SuperDraco thrusters to provide a soft controlled landing. This
redundancy on both the parachutes and thrusters is designed to ensure safe
landings for crews.
"SpaceX is working diligently to make the Dragon spacecraft the safest
vehicle ever flown," said Gwynne Shotwell, president of SpaceX. "The parachute
system is an integral part of Dragon’s ability to provide a safe landing for
nominal and abort conditions -- with this successful test we are well-positioned
to execute a full end-to-end test of the launch escape system later this
year."
The parachute test puts SpaceX a step closer to launch abort system tests.
The company currently is manufacturing the spacecraft and rocket to be used for
these flight tests.
SpaceX is on track to complete all 15 of its CCiCap milestones in 2014. All
of NASA's industry partners, including SpaceX, continue to meet their
established milestones in developing commercial crew transportation
capabilities.
