Spacecraft manufacturer XCOR comes up with an unusual two-wheeled way to test some critical bearing components from its rocket propellant piston pump.
Rocket propulsion hasn't changed much in decades, but a group of young scientists think that beamed microwave energy could power a new generation of rockets, leading to lower costs and opening space to a wide range of new businesses.
X-Tracer, who competed with the E-Tracer 7002 in the X-Prize, will receive $2.5 million. The E-Tracer is powered by an AC Propulsion electric drive system.
Before constructing the actual rovers that are sent into space, NASA scientists develop prototype bots to experiment with hardware and software. These devices were on display at the NASA Jet Propulsion Laboratory open house in Pasadena, Calif., on May 4, 2008.
Brian Muirhead of NASA's Jet Propulsion Lab tells security professionals at Black Hat that failure is not an option when taking big risks, but offers tips on avoiding it.
Future manned missions to Mars will need internal shielding and advanced propulsion systems to shorten transit times, minimizing exposure to space radiation, scientists say.
This week, we couldn't keep our eyes off the first images from Curiosity -- or one of the guys in NASA's Jet Propulsion Laboratory. Also, a life-size Rancor? Color us scared.
Flight controllers at NASA's Jet Propulsion Laboratory celebrate Curiosity, the Mars Science Laboratory rover, after it lands safely on the Red Planet at 10:32 p.m. PT Sunday.
GM Flextreme promotes electric propulsion with, er, Segways
CNET contributor Katie Linendoll takes a jump on the Flybar 800 propulsion device from SBI Enterprises and discovers that it's not quite as intuitive as its precursor.
