NASA fails to set air-speed record; Unmanned: It blows up rocket that was supposed to launch the air-breathing jetASSOCIATED PRESS
If for some reason the chemical rocket blows up and the nuclear-powered engine ends up in the ocean, the nuclear hardware still can't "go critical," Thomas said. The in-space rocket system doesn't work until it reaches orbit. Perhaps the greatest safety risks come into play during ground...
Moments later, 12 small rocket motors will fire up, horizontal velocity will be nulled out, the lander will orient itself so its solar arrays will receive maximum sunlight on the surface and it will descend to a five-mile-per-hour touchdown in the Elysium Planitia area 4.5 degrees north of ...
Astrobotic's Peregrine Lunar Lander blasted off Monday from Florida's Cape Canaveral Space Force Station, then successfully separated from its rocket. Just hours later, though, Astrobotic reported an inability to orient Peregrine's solar panel...

Under the agency’s Announcement of Collaborative Opportunity, engineers from NASA’s Marshall Space Flight Center in Huntsville, Alabama, partnered with Elementum 3D, in Erie, Colorado, to create a weldable type of aluminum that is heat resistant enough for use on rocket engines. Compared to ...
What drives the supersonic solar wind – the constant stream of solar material that blows through the entire solar system? And finally, what accelerates solar energetic particles, which can reach speeds up to more than half the speed of light as they rocket away from the Sun?
NASA's Space Environment Testbeds, or SET, will launch in June 2019 on its mission to study how to better protect satellites in space. SET will get a ride to space on a U.S. Air Force Research Lab spacecraft aboard a SpaceX Falcon Heavy rocket from NASA's Kennedy Space Center in Fl...
