Mark Watney, who struggled to stay alive in "The Martian" film, was right: It is really, really hard to survive on the Red Planet.
NASA has met or exceeded many of the goals set by the National Academies of Sciences, Engineering and Medicine in the 2013-2022 planetary decadal survey, according to a new midterm assessment.
On March 16, 1926 in Auburn, Massachusetts, American engineer Robert Goddard launched the first liquid-fueled rocket. The flight lasted a mere 2.5 seconds and ended anticlimactically 181 feet away in a snow-covered cabbage field.

Boeing recently gave journalists a behind-the-scenes look at the company's new Starliner capsule, which could start carrying astronauts to and from the International Space Station as early as next year.
Scientists have worried for years now that climate change will free carbon trapped in frozen soil in the Arctic, triggering faster climate change — but now they believe abrupt thawing below lakes is even more dangerous.
Take a look inside the CST-100 Starliner hangar, where Boeing is building the private space capsules that will fly NASA astronauts and more into space!
On Monday (Aug. 13), Curiosity photographed an odd, flat object that mission team members initially thought might have fallen off the car-size robot. But the "debris" turned out to be a Red Planet rock.
