The disc-shaped spacecraft was designed for more spacious flights to Mars
NASA will launch a disc-shaped vehicle into space on Wednesday, in order to test a roomier spacecraft designed for long-haul missions to Mars.
The Low-Density Supersonic Decelerator will lift off from a launchpad off the coast of Kauai, Hawaii, carried into the stratosphere by a massive high-altitude weather balloon. The vehicle will detach from the balloon at 120,000 feet and blast off at four times the speed of the sound, soaring to a peak altitude of 20 miles above the Earth. . . .
