Tomorrow morning at 10:05 a.m. EDT (14:05 UTC), NASA and Orbital ATK are test-firing the world's largest solid rocket booster in northern Utah. You can follow along live on NASA TV.
Lockheed Martin proposed a system to send humans to orbit Mars in the year 2028—a concept that shares many core values with The Planetary Society's report, Humans Orbiting Mars, we released last year.
The RS-25 powered the space shuttle for three decades, and will soon be used on the Space Launch System. Is it still the Ferrari of rocket engines? A deep dive on performance, reliability and the politics of rocket science.
A rocket engine that once blasted space shuttles into orbit was test-fired today in Mississippi, in preparation for its upcoming duty launching an astronaut crew to the moon.
An veteran engine from the space shuttle program will be test-fired tomorrow at NASA's Stennis Space Center in Mississippi, kicking off the next round of Space Launch System flight preparations.
The SLS core stage pathfinder is a 65-meter-long, full-size mockup of the actual rocket's main section. Just like SLS, building, assembling and utilizing the pathfinder involves multiple contractors and NASA centers around the southern U.S.
The recently passed omnibus spending bill directs NASA to work on a new upper stage for the Space Launch System, and begin development on deep space habitat modules.
As NASA kicks off a multi-decadal effort to send humans to Mars, the agency's traditional human spaceflight centers have had to adapt to new challenges—often more programmatic than technical.
November is shaping up to be a busy month for Orion and Space Launch System hardware. A human-rated flight engine is in the test stand at Stennis Space Center, and a version of Orion's service module is getting ready to cross the Atlantic.
NASA's Space Launch System officially shed the core stage's white paint job in favor of the vehicle's natural, orange-colored insulation.
NASA released a much-anticipated strategy document outlining the agency's next steps for getting humans to Mars, but the report lacks details. What should we make of it?
A key review of NASA’s Space Launch System did not uncover any major problems with the rocket's design, officials said at Stennis Space Center near Gulfport, Mississippi.
NASA completed the sixth and next-to-last test firing of its RS-25 engine Thursday in Mississippi. Four RS-25 engines power the Space Launch System core stage.
The Planetary Society will be at NASA's Stennis Space Center this Thursday for the sixth test firing of the RS-25 engine, which powers the Space Launch System.
The GAO says NASA is generally doing a good job with cost and schedule estimates for SLS, its new heavy lift rocket. But NASA is also running short on schedule margin as it works to have SLS ready for flight by November 2018.
At Kennedy Space Center, NASA's ground systems program prepares for the first flight of the Space Launch System in 2018.
A report released by NASA’s Office of Inspector General warns that the agency may be hard-pressed to have its Kennedy Space Center launch facilities ready by November 2018.
A blast of fire and smoke lit up the hills of Promontory, Utah this morning as NASA and Orbital ATK completed a test firing of a Space Launch System solid rocket booster.
With NASA and Orbital ATK preparing for an important test tomorrow in Utah, an SLS engineer describes the inner workings of the vehicle's new solid rocket boosters.
NASA will set the Space Launch System's inaugural flight date at the end of this year, according to the agency's 2016 budget request, which was released on Monday.
