Propulsion System Designed For Future Human Spaceflight
Pratt & Whitney Rocketdyne has successfully completed a
chill test and 1.9 second ignition test of NASA's J-2X engine at
John C. Stennis Space Center, MS. The J-2X upper-stage engine is in
development to power NASA's next era of human spaceflight.
"The successful start of J-2X engine testing demonstrates Pratt
& Whitney Rocketdyne is ready to be a part of the next
generation of future space solutions, including a heavy-lift launch
vehicle as well as commercial space options," said Walt Janowski,
director and program manager, J-2X Engine Program, Pratt &
Whitney Rocketdyne. "Having a plan now for future space needs is
paramount to our national security, our industrial base and our
nation's ability to continue accessing and exploring space without
being dependent on foreign providers."
The J-2X is based on a proven design that could provide a safe
and reliable solution for NASA's future heavy-lift launch vehicles.
The engine also leverages the investment taxpayers have already
made in the Constellation program and other programs such as the
space shuttle. Fueled by liquid hydrogen and liquid oxygen, the
J-2X engine will generate 294,000 pounds of thrust to lift a
spacecraft into low-Earth orbit. The engine will continue testing
over the next several months, ahead of Congressional deliberations
on additional funding for NASA.
