Stories, updates, insights, and original analysis from The Planetary Society.
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?
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.
SpaceX's plans to colonize Mars differ considerably from NASA's Journey to Mars ambitions. But direct comparison is difficult. SpaceX is able to wipe the slate clean and start fresh with a bold new approach to humans in space. NASA has no such luxury, and must use existing pieces and people to make their goals a reality.
After 10 days, four NASA centers, two contractors, and hundreds of miles, Casey Dreier shares his initial reflections on the state of NASA's Space Launch System rocket and its future.
A test stand problem cut short today's test-firing of a Space Launch System development engine at NASA's Stennis Space Center in Mississippi.
NASA and Orbital ATK successfully completed a qualification motor firing of a five-segment solid rocket booster that will fly on the Space Launch System in 2018.
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.
