How can NASA put a two-story building on Mars? Its very own flying saucer
NASA's LDSD aims to to slow down the descent of a large payload at supersonic speeds through the thin atmosphere of a planet like Mars by creating atmospheric drag.
Looking almost exactly like a miniature version of the spaceship that beguiled Richard Dreyfus in 1977â€™s â€śClose Encounters of the Third Kind,â€ť the new LDSD is propped up on a special, multipronged trailer in the five-story room where it was assembled here. The press had to don surgeon hats, booties, and special outerwear to get close, while scientists explained the advancing needs of exploring Mars.
The new saucer, er, LDSD, is about 6 feet high and 22 feet in diameter.

Flying saucers are going to be reality very soon. NASA is reportedly testing its Low-density Supersonic Decelerator (LDSD) which has been designed to increase the agencies payload delivery capacity for future missions.

You might think what you just saw flying across the night sky was a spacecraft from another planet. But, in fact, it was just NASA's new Low-Density Supersonic Decelerator (LDSD), which the agency is hoping to eventually use to bring large payloads to other planets. It might even be used in a mission to Mars as soon as 2018, with major tech demos...
