Stories, updates, insights, and original analysis from The Planetary Society.
NASA is planning for a 30-day mission to lunar orbit in 2024.
Getting NASA out of the rocket business is more complicated than you think.
Will NASA's Space Launch System be ready to launch a Europa mission in 2022?
Vice President Mike Pence kicked off the National Space Council's first meeting today by declaring Americans will return to the Moon. Casey Dreier and Jason Davis analyze this new direction for NASA's human spaceflight program.
Last week, NASA revealed an updated design for the Space Launch System, featuring black-and-white checkerboards streaking down each of the vehicle's solid rocket boosters.
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's new heavy lift rocket is currently scheduled to launch the Orion spacecraft on a test flight next year. But all signs are pointing to a probable delay.
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.
