NASA Tested Orion Spaceship’s Parachutes with Mock Glitch in 2013. NASA conducted a successful test of its next-generation spaceship last week.
An exercise designed to simulate two different types of parachute failures during landing.
A prototype of the Orion spacecraft landed safely in the Arizona desert May 1, 2013 after it was dropped 25,000 feet (7,620 m) from a C-17 airplane as it flew over Yuma, Ariz.
During the test, the mock capsule was traveling about 250 miles per hour (402 km/h) when its parachutes were deployed — the highest speed the Orion spacecraft has experienced so far in its testing phase, NASA officials said in a statement.
To simulate a failure, engineers rigged one of Orion’s three main parachutes so that it did not inflate after the spacecraft was dropped from the plane. In addition, one of the two drogue chutes, which are used to reorient and slow the capsule as the main parachutes inflate, was not deployed.

Simulating a parachute failure enables NASA to demonstrate that the system is reliable even when something goes wrong. Data collected from the tests also help engineers refine their models and designs.
“Parachute deployment is inherently chaotic and not easily predictable,” Stu McClung, Orion’s landing and recovery system manager, said in a statement. “Gravity never takes any time off — there’s no timeout. The end result can be very unforgiving. That’s why we test.
If we have problems with the system, we want to know about them now.”
This type of parachute failure was one of the most challenging to simulate so far, but is a crucial step toward demonstrating that the spacecraft is safe enough to carry humans, said Chris Johnson, NASA’s project manager for the Orion parachute assembly system.
