'A Nation of Quitters': 45 Years Since the Summer Apollo Ended (Part 2)

Training for a mission which, for one of them, would never come to pass, Dick Gordon (left) and Jack Schmitt work with a mockup of the Lunar Roving Vehicle (LRV) during their Apollo 15 backup duties. Schmitt’s importance as a professional geologist assured him a seat on Apollo 17. Gordon was not so lucky. […]

In 2011, Hollywood had us believe that the crew of Apollo 18 fell victim to spider-like aliens and a sinister conspiracy, spearheaded by the Department […]

New Study Suggests Abundance of Nitrogen on Pluto May Be Due to Cryovolcanism

A spectacular image of Pluto's atmosphere backlit by the Sun, taken during New Horizons' closest approach to Pluto on July 14. The bright halo of Pluto's atmosphere is caused by the scattering of sunlight from nitrogen, a compound that dominates the planet's atmosphere. A new study suggests that the source of all this nitrogen might be cryovolcanism on the distant planet. Image Credit: NASA/JHUAPL/SwRI

SLS Development RS-25 Engine Ignites for Successful Full Duration Test Fire #6

The world's most efficient rocket engine came to life again today, unleashing 512,000 pounds of thrust and a thunderous roar across southern Mississippi and NASA's Stennis Space Center during a 535-second full power test fire. The same engine that powered the space shuttle so reliably for years, the RS-25, will again be employed for NASA's Space Launch System, upgraded to meet the new requirements for what will become the most powerful rocket in history.
