Promising technology for the development of Mars.

Specialists of the American space agency NASA has successfully tested the world’s first “flying saucer”. Apparatus Low-Density Supersonic Decelerator (aerodynamic inflatable retarder supersonic speed) was to begin development of the Cosmos in June. Scenes from the successful launch of NASA LDSD were presented only in the beginning of August.
According to official reports, the unit was launched from the missile range in Hawaii. Advanced development of American scientists is designed to ensure a safe landing of aircraft, which in the future will be to fly to Mars.
The aim of the experimental flight tests was to determine the maximum height and speed, which can be achieved by the machine having such an unusual space technology for terrestrial form.
In addition, NASA noted that the following two stages of testing will take place next year. The first flight of an inflatable decelerator was done first at a height of 36.5 km (LDSD was raised with the help of a balloon with helium and rocket engines).
After that, the rocket engines were included in the full power and raised the machine up to 55 kilometers. It is at this altitude, the atmosphere is similar to that of Mars.
Next specialists increased the velocity of the “flying saucer” to 3.8 Mach, and then began a process of reduction using the parachute and inflatable braking device.
Разработка NASA consists of two inhibitors, which resemble the familiar all the plate, and a parachute for more effective braking. At the start of braking, works the “plates” that are designed to slow down any of the operating spacecraft, extinguishing their supersonic speed. After that it starts to brake parachute, providing a soft landing.
«It was a good test. We have received new information about using the braking parachute. It can rewrite the book on high-speed braking operations, “- said the lead researcher in California LDSD Ian Clark (Ian Clarke).
