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.
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 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.
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 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.
