The first flight test of NASA's new manned spacecraft may be six months away, but agency engineers are already looking forward to what they will learn from the trial. NASA's Orion capsule, which is designed to take astronauts to Mars and other farflung destinations, will blast into space ...
And so the Mars Roadmap committee is tasked with deciding what first steps should be taken toward the design of a manned Mars mission, and what Mars-directed unmanned advance test missions are needed for such a mission. The Committee was distinctly frustrated by the fact that manned Mars fligh...
China is preparing to launch a new three-person mission to complete work on its permanent orbiting space station, the China Manned Space Agency said Saturday. The Shenzhou 14 crew will spend six months on the Tiangong ...
Hydrazine, which is made out of hydrogen and nitrogen, is extremely flammable, dangerous for the environment, and extremely toxic if inhaled, making it tricky to use on manned missions. Michael Berman, Hawkins' colleague on the project, says missions run with hydrazine were d...
"The new generation of manned space transportation vehicle, which has been tested, could carry six to seven astronauts, while our Shenzhou spacecraft could only take three astronauts." With a launch mass of 21.6 tons, the next-generation piloted spacecraft is China's largest return and reentry...
