NASA tests separation descent steps rover Mars 2020

When the start very soon the mission Mars 2020 in the framework of which the fourth planet of the solar system is planned to send the rover will enter into its final stage (and this should happen, it is estimated that NASA August 5, 2022), the rover to study the Red Planet will be required to successfully to land on the planet's surface and begin its mission. This will draw a more advanced version of the technology, which has already proven itself on landing the Mars rover Curiosity in 2012. And this technology already being tested NASA engineers.

so it will look about landing Mars rover 2020

How to put the rover?

At the moment, experts of the American space agency conducted full swing stages tests, which will be used during landing of the rover. Just recently, in Pasadena, California, in the laboratory of the JPL rocket engines, owned by NASA's, we passed the first tests, including explosive separation stage of the rover. If you are interested in this issue, we recommend that you subscribe to our channel Telegram to miss nothing. Self planting process should be as follows: when the rover reaches the upper limit of the atmosphere Mars at hypersonic speeds, it will be protected aerodynamic heat shield and a rear shell, which will not only reflect heat from entering the atmosphere at the time of deceleration, but will give the machine a certain lifting strength, allowing him to maneuver. When the rate of decline due to this, a series of parachutes will slow the fall even more.

According to calculations, after the spacecraft will reset its cruise stage and the heat shield at an altitude of 1 mile (1, 6 km), the lander will be moving at the speed of 170 miles per hour (274 km / h). Shortly thereafter, will work eight engines. This will allow the rover to slow down to a safe landing, and will provide an opportunity to control the flight to land navigation and search of a safe landing area on the Martian surface. Sami tests were as follows: the lander with the rover has been raised to a height of 10 meters with a crane, and then separated from the rover unit and successfully landed.

Device Start-up, which would have kept the rover and the trigger stage together was the work of the day, - said Ryan Wang Shilifgaard, assembly engineer team for the rover mission, Mars 2020. Now that the testing is finished, the stage for the descent and the rover "meet" only Cape Canaveral next spring during assembly before starting the machine.

Engineers also tested other systems for controlled descent - namely, rocket engines, which we discussed above. To do this, suspended on three nylon ropes rover at a height of 7, 5 meters makes the wheels turn 90 degrees to the past acted as landing gear.

According to NASA, JPL after the completion of testing their equipment and computers, including surface thermal test to simulate the temperature and pressure of Mars, the rover will be sent to the assembly and installation on the rocket United Launch Alliance Atlas V, the launch of which is to take place in July 2020.
