The largest, most powerful rocket booster ever built successfully fired up Wednesday for a major-milestone ground test in preparation for future missions to help propel NASA’s Space Launch System (SLS) rocket and Orion spacecraft to deep space destinations, including an asteroid and Mars. The booster fired for two minutes, the same amount of time it […]
NASA and ATK (NYSE: ATK) have completed installing the first Space Launch System booster qualification motor, QM-1, in a specialized test stand in Utah. The largest solid rocket motor ever built for flight, QM-1 is now being prepared for its static-fire test, which is scheduled for March 11. The first qualification motor for NASA’s Space […]
Aerojet Rocketdyne, a GenCorp (NYSE:GY) company, successfully completed the first in a series of hot-fire tests on the RS-25 rocket engine, which will help power NASA’s new Space Launch System (SLS) and carry humans farther into space than ever before. The test, conducted in the A-1 facility at NASA’s Stennis Space Center in Mississippi, demonstrated […]
The new year is off to a hot start for NASA’s Space Launch System (SLS). The engine that will drive America’s next great rocket to deep space blazed through its first successful test Jan. 9 at the agency’s Stennis Space Center near Bay St. Louis, Mississippi. The RS-25, formerly the space shuttle main engine, fired […]
NASA’s Stennis Space Center has test fired the first RS-25 (unit E0525) of the Space Launch System (SLS) era on Friday, marking the beginning of a new career for the famous engine. Four of the former Space Shuttle Main Engines (SSME) are set to power each SLS during the ride to orbit, opening with Exploration […]
The engine controller unit on the RS-25 — formerly known as the space shuttle main engine — helped propel all of the space shuttle missions to space. It allows communication between the vehicle and the engine, relaying commands to the engine and transmitting data back to the vehicle. The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine’s health and status. Just like the ever-evolving computer, the engine controller unit needed a “refresh” to provide the capability necessary for four RS-25 engines to power the core stage of NASA’s new rocket, the Space Launch System (SLS), to deep space missions.
