Tests of Martian lander NASA ended in failure Bashny.Net

Unfortunately, testing Martian "flying saucer», Low-Density Supersonic Decelerator (LDSD), ended in failure. It is worth remembering that this device should ensure that the landing of heavy vehicles on the surface of Mars.

The problem was in the parachute - in rarefied atmosphere he has torn, opened only partially. As a result - landing with the help of parachutes failed. According to experts of NASA, the parachute broke as a result of the influence of the forces acting on the "plate" at supersonic motion.



All other steps, including the lifting of Low-Density Supersonic Decelerator to a predetermined height, were successful. As a result, the drive landing in the Pacific Ocean. Raising sistey conducted using the stratospheric balloon that LDSD raised to a height of 37 kilometers. Then turn on the jet engine, and the platform has risen to a height of 55 km.



Here, at this height, the platform was inflated, thus reducing the rate of fall twice. At lower speeds, according to the plan was to open the parachute, whose diameter is 30 meters. At this stage, just happened to fail.
