SpaceX's reusable rocket prototype, dubbed Grasshopper, is designed for vertical takeoffs and landings, but in the commercial spacecraft's latest test flight, Grasshopper proved it could hop sideways, too.
14 August 2013, 01:48 PM ET
The Falcon 9 test rig (codenamed Grasshopper) successfully completed a 'divert' test, with the ship making a 100m lateral maneuver while reaching an altitude of 250m. This test demonstrated the ships ability to make more aggressive maneuvers.

Billionaire entrepreneur unveiled new details today about his "Hyperloop" project, a superfast transportation system that could ferry passengers between Los Angeles and San Francisco in 30 minutes. Can it really be built?
12 August 2013, 06:40 PM ET
The Hyperloop, Musk revealed today (Aug. 12), is a solar-powered transportation system that could rocket passenger-packed pods through long tubes at 760 mph or so (1,220 km/h). The technology could cut the LA-San Francisco travel time to 30 minutes.
