Stories, updates, insights, and original analysis from The Planetary Society.
In the second and final chapter of our series, we’ll explore what the rocket equation has to say about travel through the solar system, using the example of launching a rocket to Pluto.
Have you ever wanted to learn the fundamental physics behind one of the most basic concepts of rocket science? In part one of our two-part series, we explore the foundations of the famous rocket equation.
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?
Today, China launched its largest rocket yet, the Long March 5, from the new coastal launch center on Hainan Island. The launch is a major step forward on the country's path to deep space.
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.
The OSIRIS-REx mission passed its flight readiness review yesterday, clearing the way for the spacecraft to launch on Thursday, September 8. Here's a schedule of next week's NASA TV briefings and a photo album of the launch preparations.
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.
SpaceX returned its Falcon 9 rocket to flight with flair tonight, successfully deploying 11 communications satellites after returning the rocket's first stage to Cape Canaveral for an upright landing.
