SpaceX says 'picture perfect' test paves way for human mission

CAPE CANAVERAL, Fla. (Reuters) - Elon
Musk's SpaceX simulated a successful emergency landing on Sunday in a
dramatic test of a crucial abort system on an unmanned astronaut
capsule, a big step its mission to fly NASA astronauts for the first
time as soon as this spring.
A Crew Dragon astronaut capsule launched at 10:30 a.m. and softly
splashed down about 19 miles (32 km) off the coast of Cape Canaveral in
Florida about eight minutes later, after ejecting itself from a rocket
that cut off its engines 12 miles (19 km) above the ocean to mimic a
launch failure.
Crew Dragon detached from the Falcon 9 rocket at "more than double the
speed of sound," Musk told reporters, at 131,000 feet (40km) above the
Atlantic Ocean -- roughly twice the altitude of a commercial jetliner.
"It is a picture perfect mission. It went as well as one can possibly
expect," Musk said at a press conference.
National Aeronautics and Space Administration administrator Jim
Bridenstine also described the test as a success.
The first mission with humans aboard, which will be the final test
mission before NASA's commercial crew program becomes operational, is
scheduled for the second quarter of this year, after the spacecraft is
completed no later than March, Musk said.
In what was a key trial ahead of carrying humans, SpaceX also tested its
rescue teams' response after splash down. They scrambled toward Crew
Dragon with the U.S. Air Force's Detachment 3 emergency rescue teams in
tow — a vital part of the test to practice a rescue mission to retrieve
astronauts from the capsule.
Crew Dragon, an acorn-shaped pod that can seat seven astronauts, fired
on-board thrusters to detach itself from the rocket less than two
minutes after liftoff, simulating an emergency abort scenario to prove
it can return astronauts to safety. Each stage of the test prompted loud
cheers from SpaceX crew members watching the footage from back on land.
The test is crucial to qualify the capsule to fly humans to the
International Space Station, something NASA expects to come as soon as
mid-2020. It follows years of development and delays as the United
States has sought to revive its human spaceflight program through
private partnerships.

NASA awarded $4.2 billion to Boeing and $2.5 billion to SpaceX in
2014 to develop separate capsule systems capable of ferrying
astronauts to the space station from U.S. soil for the first time
since NASA's space shuttle program ended in 2011. The space agency
has since relied on Russian spacecraft for rides to the space
station.
During the test Crew Dragon used its so-called SuperDraco thrusters
to jet itself away from the rocket at supersonic speeds of up to
1,500 miles per hour (2,400 kph). The Falcon 9 booster free-fell
back to the ocean, with its first stage crashing into the waves and
creating a tall plume of smoke seen on the horizon.
The capsule deployed four parachutes to slow its descent, and
carried two human-shaped test dummies on seats fitted with motion
sensors to collect data on the immense g-force — the effect of
acceleration on the body — astronauts would be subjected to during
abort.
The test was originally scheduled for mid-2019 but was delayed after
a Crew Dragon capsule exploded in April on a test stand just before
firing its launch abort thrusters, triggering a lengthy
investigation.
SpaceX-led investigators in July zeroed in on a previously unknown
explosive reaction between a titanium valve and a propellant used to
ignite the thrusters. A SpaceX official said the company completed
the investigation within the last week.
