NASA will launch a "flying saucer" June 3
NASA announced on testing radically new aircraft, which the agency plans to operate Shipping astronauts and payload on the surface of Mars with a payload.
The device, called Low-Density Supersonic Decelerator (aerodynamic inflatable retarder supersonic speed or abbreviated LDSD , want to use for the landing of astronauts with a payload on the surface of Mars. In the US Agency considers that due to the "breakthrough technologies" retarder can carry out a successful landing in a rarefied atmosphere of the planet.
At the moment, NASA has two such machines. They are shaped saucers have an inflatable device and a parachute. Diameter one of which 6 m., Second - 8 meters. The agency expects that the device will deliver a smaller diameter "space truck" and the eight-meter - manned spacecraft.
The first test will be held on June 3 LDSD em> and will consist in the fact that the device will deliver a conditional vehicle to an altitude of 36.5 km, and then rises up to 54.8 km. There, he will conduct a test of two innovative technologies and will develop speed at 3.5 times the speed of sound. Tests can be viewed on the website NASA.
The agency clarified that its experts doubt the success of the test, but in any case they will test two more such devices in the summer of next year.
