|SSC gives SpaceX Mars plan a boost

To say that commercial space company SpaceX is ambitious is a huge
understatement. Its space vehicles supply the International Space Station and will
one day transport astronauts. It’s also working on ways to get launchers to land back
on Earth vertically, like in movies of old, and creating new spaceships that will take
colonists to Mars.
And South Mississippi is playing a major role in development of the next-generation
rocket engine that will make SpaceX Mars trips possible.
It’s been a year since SpaceX cut the ribbon on its test stand at NASA’s Stennis
Space Center. Since then, SpaceX has been testing components for its Raptor
rocket engine, specifically injectors and combustion chambers, with additional
components ready for testing in the near future. In a typical week, SpaceX conducts
multiple tests, spokesman John Taylor said.
Getting SpaceX to pick South Mississippi to play a role in the company’s future was
nothing short of monumental. Mississippi’s top elected and economic development
officials were on hand at the April 21, 2014, invitation-only ceremony to welcome the
company to the Stennis family of tenants.
Brent Christensen, executive director of the Mississippi Development Authority, said
SpaceX “strengthens the state’s position as an industry leader in the global
aerospace sector and demonstrates to the world that Stennis is an ideal location for
aerospace companies with sophisticated research and development needs.”
The state of Mississippi and Hancock County’s economic development commission
assisted in improving the E-2 test stand SpaceX is using for research and
“With the strong cooperation of Stennis Space Center, the Mississippi Development
Authority and the Hancock County Port and Harbor Commission, SpaceX was able to
begin testing at its facility within months of signing its agreement with NASA and
Stennis Space Center,” said Taylor.
Landing a SpaceX operation at SSC earned the Port and Harbor Commission the top
economic development award from the Mississippi Economic Development Council.
Ashley Edwards, HCPHC executive director, called SpaceX one of the most
innovative and exciting companies in the world and just the caliber of world-class
companies the county is recruiting.
“We are diligently working with SpaceX to grow their footprint in Hancock County and
solidify their Stennis Space Center operation as one of their leading locations for the
company’s future,” Edwards said.
SpaceX is developing the methane-fueled Raptor as a reusable engine for a heavy-
lift launch vehicle. SpaceX’s goal is to reach Mars in the next 15 or so years. It’s the
latest in the fast-moving history of Space Exploration Technologies Corp., founded
13 years ago by Elon Musk, co-founder of PayPal and CEO of Tesla Motors.
SpaceX, of Hawthorne, Calif., designs, manufactures and launches rockets and
spacecraft, and is a star of the $52 billion industry. In 2012 it won a $440 million
agreement with NASA to develop the Dragon spacecraft to transport humans into
space. In May 2012 Dragon became the first commercial spacecraft to dock to the
International Space Station, deliver cargo and return to Earth.
More recently, NASA chose SpaceX and Boeing for the combined $6.8 billion
contract to transport astronauts to the International Space Station by 2017.
Taylor said SpaceX chose Stennis Space Center based on its long resume of testing
for the Apollo and Space Shuttle programs and more recently for government and
private sector propulsion systems.
“Stennis is home to some of the most advanced rocket test facilities in the world and
decades of experience developing new engine technologies. We are thrilled to work
with this talented group to ensure a rapid and comprehensive test program,” he said.
The agreement with NASA, announced in 2013, called for SpaceX to revive the
dormant E-2 test stand with high-pressure methane capability. Without revealing
details, Taylor said SpaceX made “significant investments” upgrading the hardware
at the E complex, “investments that will remain for NASA and other private
contractors to use at the conclusion of this test effort.”
He said SpaceX has also paid for the use of the stand and of Stennis’ workforce,
“representing true private sector investment into the center.”
The number of employees working at Stennis varies, Taylor said, depending on the
testing being done. Nationwide, SpaceX employs more than 3,500 people.
“We looked to Stennis to be an R&D test center for the company and will leverage
these capabilities to accelerate the Raptor development effort,” Taylor said. “In
SpaceX’s view, Stennis has some of the best high-pressure test stands in the world.”
The E complex is one of several that make Stennis the nation's largest rocket engine
test complex. Established in 1961, Stennis has adapted to a succession of new
programs that have brought opportunities for testing innovative engines and
The construction of one new test structure at SSC, however, generated national
headlines and criticism about government waste.
The 300-foot A-3 test stand was built to test engines in a vacuum to simulate high
altitude operation up to 100,000 feet.
A-3 was also designed for tests that ran the full duration of actual flights and to
gimbal or rotate the engines in the same way they would move during flight. Those
capabilities would have given engineers unique opportunities to test engine
performance on the ground.
But the rocket program A-3 was built to support was cancelled before construction of
the stand was complete. On orders from Congress, the $350 million-plus stand was
finished and then mothballed.
For now, the future of A-3 is on hold. Valerie Buckingham, the Stennis Space Center
news chief, said the stand is being maintained “until we have a test objective
identified. We don’t have any mission right now.”
