NASA conducted a combined chill test and 1.9-second ignition test July 14 of the next-generation J-2X rocket engine that could help carry humans beyond low-Earth orbit to deep space.
The test at John C. Stennis Space Center is the first in a series of tests that will be conducted on the J-2X engine, which is being developed for NASA's Marshall Space Flight Center in Huntsville, Ala., by Pratt and Whitney Rocketdyne.
The ignition test on the A-2 Test Stand is the first of a series of firings over the next several months.
Collected data will verify the engine functions as designed.
The J-2X engine uses liquid hydrogen and liquid oxygen as fuel, which can be mixed to generate 294,000 pounds of thrust to lift a spacecraft into low-Earth orbit or 242,000 pounds of thrust to power a spacecraft from low-Earth orbit into deep space.
The engine is designed to start and restart in space.
