NASA Conducts New Orion Parachute Test
On Feb. 29, NASA successfully conducted another drop test of the Orion crew vehicle's entry, descent and landing parachutes high above the Arizona desert in preparation for the vehicle's orbital flight test in 2014. Orion will carry astronauts deeper into space than ever before, provide emergency abort capability, sustain the crew during space travel and ensure a safe re-entry and landing.
An Air Force C-17 plane dropped a test version of Orion from an altitude of 25,000 feet above the U.S. Army's Yuma Proving Grounds in Arizona. Orion's drogue chutes were deployed between 15,000 and 20,000 feet, followed by the pilot parachutes, which deployed the main landing parachutes. Orion landed on the desert floor at a speed of almost 17 mph, well below the maximum designed touchdown speed of the spacecraft.
Since 2007, the Orion program has conducted a vigorous parachute air and ground test program and provided the chutes for NASA´s successful pad abort test in 2010. All of the tests build an understanding of the chutes´ technical performance for eventual human-rated certification.

This particular drop test examined the wake — or the disturbance of the air flow behind Orion — that is caused by the spacecraft. This was the latest in a series of parachute drop tests conducted by NASA at the U.S. Army´s Proving Grounds in Yuma, Ariz. Photo credit: NASA
