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 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.
NASA completed a 500-second test firing of the RS-25 engine, which will power the core stage of the Space Launch System.
On the surface, NASA's humans to Mars plans seem vague and disjointed. But that's because the agency is playing the long game. Right now, it may be the only game they can play.
NASA's Space Launch System passed a critical milestone yesterday, but buried within the announcement was news that the first launch could slip by nearly a year.
Europa may get a mission...eventually. We give our first take on the 2015 NASA Budget request. How does Planetary Exploration fare? Which projects were cancelled? Will NASA capture an asteroid? And most importantly, what can you do about it?
The House Science Committee is considering giving a select few NASA programs special protected status against cancellation.
The House of Representatives held a hearing today to discuss their proposed NASA authorization bill, which would fund Planetary Science, cut Earth Science, forbid asteroid retrieval, and command NASA to pursue a path to Mars via the Moon.
