The national aeronautic and space USA (NASA) conducted a successful launch of the carrier rocket Atlas-5 with the new Mars Rover “Perseverance” (Perseverance), and a compact helicopter Ingenuity. For the next 7 months, the spacecraft will move in the direction of Mars then will land on the red planet and will search for extraterrestrial life, tells Ddnews.
The new Rover is Perseverance is based on the same platform as the current running on the surface of the red planet, the Rover Curiosity. However, the main mission of the new marched will be different. His task will be to search for organic compounds, potentially indicating the presence of microorganisms in the past or present. In addition, it will study the climate of Mars and attempt to synthesize oxygen from its atmosphere.
An additional and no less important task of the new Rover will be collecting samples of Martian soil. In the context of a future NASA mission to the Red planet, scheduled for 2026, when our planetary neighbor will go next research spacecraft, these samples are planned for the first time in history to bring to Earth for study.
Another interesting feature of the new mission is that, together with marched NASA sent to the Red planet samples of the various materials that will be used for production of space suits astronauts for a manned mission to the moon and later to Mars. These materials should be both durable, lightweight and heat resistant to withstand the rigours of space, and lunar and Martian conditions.
The Rover “Perseverance” (Perseverance)
On Board the Rover are samples of the visor of the helmet of the suit is made of polycarbonate, as well as several samples of different Teflon. In addition, went to Mars samples ortho-fabric, which is a combination of materials such as Gore-Tex, Kevlar and Nomex fire retardant fabric. Such material is already used in outer skin of space suits of the astronauts. Also, scientists and engineers want to check the Vectran material resistant to cuts and tearing synthetic fabric that is used in the manufacture of gloves of astronauts. The challenge is how to check how to change the strength of these materials for the time being in the extreme conditions of the Martian environment.
As for the helicopter Ingenuity, then sent it to Mars, rather to test the feasibility of using such devices. If he can rise into the air, it will be the first controlled atmospheric flight outside of the Earth. In addition to checking the possibility of flight in the Martian atmosphere it also will be the exploration of the surface around the Rover.
To arrive at Mars, the spacecraft needs Perseverance and Ingenuity on 18 February 2021. Planting will take place in the crater Lake. Scientists believe that this place in the past was the Delta of the river. As in the case of Rover, the new Rover will first slow down the heat shield, then parachutes, and for the final part of landing is to answer “sky crane” — a special platform with rocket engines that will hang low above the surface of Mars and pull the apparatus on the ropes. The nominal lifetime of the mission after landing is one year. But if you do not have insurmountable technical difficulties, the Rover will be able to work on the surface of the red planet and the longer term.
