WASHINGTON -- A complicated, high-altitude test Wednesday demonstrated NASA's
new Orion spacecraft could land safely even if one of its parachutes failed.
The 10th in a series of evaluations to check out the Orion multipurpose crew
vehicle's parachute system dropped the test capsule from a C-17 aircraft at its
highest altitude yet, 35,000 feet above the Arizona desert. One of three massive
main parachutes was cut away early on purpose, leaving the spacecraft to land
with only two. The test at the U.S. Army's Yuma Proving Ground was the
highest-altitude test of a human spacecraft parachute since NASA's Apollo
Program.
During previous tests, a mock capsule was dropped from a height of 25,000
feet and the parachutes deployed at no higher than 22,000 feet. The extra 10,000
feet of altitude at the beginning of Wednesday's test made the demonstration the
best so far of Orion's parachute flight and landing.
"The closer we can get to actual flight conditions, the more confidence we
gain in the system," said Chris Johnson, project manager for the Orion capsule
parachute assembly system at NASA's Johnson Space Center in Houston. "What we
saw today -- other than the failures we put in on purpose -- is very similar to
what Orion will look like coming back during Exploration Flight Test-1's Earth
entry next year."
During its return from space, Orion's parachute system will begin to deploy
25,000 feet above the ground.
Engineers gathered data on the effects of losing a parachute during the
descent. The team already proved Orion can land with just two of its three main
parachutes, but this was the first opportunity to study how one parachute
pulling away in mid-flight might affect the remaining two.
"We wanted to know what would happen if a cable got hooked around a sharp
edge and snapped off when the parachutes deployed," said Stu McClung, Orion's
landing and recovery system manager at Johnson. "We don't think that would ever
happen, but if it did, would it cause other failures? We want to know everything
that could possibly go wrong, so that we can fix it before it does."
The test was part of a series of parachute tests that will enable NASA to
certify Orion to carry humans into space. The system already has met the
necessary requirements for Orion's first mission, Exploration Flight Test-1
(EFT-1), in September 2014. During that flight, Orion will travel 3,600 miles
into orbit then return to Earth at speeds as fast as 20,000 mph, putting the
parachute system to the test again as it lands in the Pacific
Ocean.
UPDATE: NASA Invites Media to View Orion Stationary
Recovery Testing
NASA is offering media the opportunity to view key testing of splashdown
recovery operations for the agency's Orion spacecraft on Thursday, Aug. 15, at
Naval Station Norfolk in Virginia.
NASA and the U.S. Navy are conducting tests to prepare for recovery of the
Orion crew module and forward bay cover on its return from deep space missions.
The stationary recovery test will allow the teams to demonstrate and evaluate
the recovery processes, procedures, hardware and personnel in a controlled
environment before conducting a second recovery test next year in open
waters.
A media briefing also will take place during a portion of the testing. The
briefing participants include:
-- Scott Wilson, manager, Offline Processing and Infrastructure for
Development, Ground Systems Development and Operations (GSDO) Program
-- Jim Hamblin, landing and recovery element operations manager, GSDO Program
-- Navy Commander Brett Moyes, Future Plans Branch chief, U.S. Fleet Forces
-- Jim Hamblin, landing and recovery element operations manager, GSDO Program
-- Navy Commander Brett Moyes, Future Plans Branch chief, U.S. Fleet Forces
International media who want to attend must respond by 4 p.m. EDT Friday,
Aug. 9. U.S. media must respond by noon Wednesday, Aug. 14. To respond, contact
Sasha Congiu by email at
sasha.r.congiu@nasa.gov or by phone at
757-272-9859.
Journalists should arrive by 12:30 p.m. at the Naval Station Norfolk Tour
& Information Center for transportation to the testing area. Live trucks
should arrive no later than 10:30 a.m. The information center is located at 9079
Hampton Blvd. in Norfolk. Close-toed shoes and pants are required.
Orion is America's new spacecraft that will take astronauts to destinations
not yet explored by humans, including an asteroid and Mars. It will have an
emergency abort capability, sustain the crew during space travel and provide
safe re-entry from deep space. The first spacecraft will launch on Exploration
Flight Test-1 in September 2014, an uncrewed mission that will allow engineers
to examine many of Orion's systems.
