VIDEO: NASA Will Try Again To Test 'flying Saucer' Vehicle
After several weather delays, NASA will try to launch a "flying saucer" into Earth's atmosphere Saturday to test technology that could be used to land on Mars. The attempt off the coast of the Hawaiian island of Kauai will test the disc-shaped vehicle and a giant parachute. The test at the Kauai military range has been postponed several times since June 2 because of winds. The low-density supersonic decelerator, as it's officially known, will ascend into the skies dangling from a gargantuan balloon filled with helium.
