The Space Launch System and Orion won't fly until 2019, and NASA is sticking with its original plan not to include astronauts for the maiden mission. Here is a timeline of some of the programs' major twists and turns over the years.
NASA revealed its most concrete plan yet for sending humans back into deep space, centered around a small lunar space station and a reusable transport ship to carry astronauts to Mars and back.
NASA has only flown astronauts aboard a rocket's first flight once, when John Young and Bob Crippen took space shuttle Columbia on the boldest test flight in history. What are the risks of repeating the feat for SLS?
This morning's launch of an uncrewed Russian Progress cargo spacecraft to the International Space Station went awry. Following a third-stage failure, the vehicle reentered Earth's atmosphere and broke apart over southern Siberia in Russia.
International Space Station (ISS) project partners are inching ever closer toward an agreement to begin the development of a new human outpost in the vicinity of the Moon. If successful, the cis-lunar space station (a space station in the vicinity of the Moon) will be the largest international space project to date, influencing the direction of human space flight for decades to come.
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.
The shell of NASA's next Orion spacecraft has been welded together and shipped to Kennedy Space Center, Florida. Here's a photo recap of the assembly and transport process.
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.
The Orion European Service Module test article has arrived at NASA Glenn Research Center's Plum Brook Station in Sandusky, Ohio, where it's being prepared for acoustic and vibration testing.
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?
NASA's Orion spacecraft has officially moved from preliminary design to fabrication, but the agency says the first crewed flight of the vehicle could slip two years, from 2021 to 2023.
NASA’s Orion spacecraft completed a key parachute test Aug. 26 at the U.S. Army Yuma Proving Ground in Yuma, Arizona.
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.
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.
