NASA and its international partners have been given the green light to begin construction on a new Mars lander to be launched in 2016, after it completed a successful Mission Critical Design Review on Friday.
NASA plans to put its planet-hunting Kepler telescope back on the job. The space agency approved Kepler for a new mission after a positioning system problem sidelined the observatory last year, officials said on Friday.
Almost 600 items that have traveled to the Moon via NASA's Apollo space missions are being offered in RR Auction's Space & Aviation online sale, which begins Thursday and runs through May 22.
A new video, released by NASA, shows two super-dense neutron stars destroy each other in a cataclysmic cosmic merger event that eventually creates a black hole.
