  Something is happening now at NASA

Scientists are working hard on the Mars 2020 mission, a critical step to better understand the planet that could become man's second home.

Work has begun on the next Mars The Roveor mission was established to fly to the red planet in 2020. Known as Mars 2020, it will be the most important mission there so far, and will look for signs of ancient life that can have lived on the planet for a long time. [19659004] The Jet Propulsion Laboratory of NASA began to build the Mars 2020 rover that would be launched in 2020 and would arrive in early 2021. The rover will carry seven instruments that will collect soil and rock samples, with a design similar to that of the Rover Curiosity that has been operating on Mars in 2020. The hardware will be approximately 85 percent similar.

And it will be an important step since humanity hopes to learn more about the planet and its history before sending a human colony to the red planet. somet In the decade of 2030 approximately, although the founder of SpaceX, Elon Musk, wants to do it much earlier. Mars 2020 would focus on a region of Mars where liquid water once flowed.

The following is the description of the mission of NASA in the Mars 2020 project.

The rover mission of Mars 2020 is part of NASA's Mars Exploration Program, long-term robotic exploration effort of the planet Red. The Mars 2020 mission addresses high-priority scientific objectives for Mars exploration, including key questions about the potential for life on Mars. The mission takes the next step not only by looking for signs of habitable conditions on Mars in the ancient past, but also by looking for signs of past microbial life. The Mars 2020 rover introduces a drill that can collect core samples from the most promising rocks and soils and set them aside in a "hiding spot" on the surface of Mars. A future mission could return these samples to Earth.

That would help scientists study samples in laboratories with special room-sized equipment that would be too large to carry to Mars. The mission also provides opportunities to gather knowledge and demonstrate technologies that address the challenges of future human expeditions to Mars. These include testing a method to produce oxygen from the Martian atmosphere, identifying other resources (such as subsurface water), improving landing techniques, and characterizing climate, dust, and other potential environmental conditions that could affect future astronauts who live and work in the area. Mars. 19659004] The mission is scheduled for a launch opportunity in July / August 2020 when Earth and Mars are in good position relative to one another to land on Mars. That is, it takes less power to travel to Mars at this time, compared to other times when Earth and Mars are in different positions in their orbits. To keep the costs and risks of the mission as low as possible, the design of Mars 2020 is based on the successful architecture of the NASA Mars Science Laboratory, which includes its Curiosity rover and its proven landing system.

The mission is based on successful technological innovations, especially for entry, descent and landing (EDL). Like the NASA Curiosity rover (Mars Science Laboratory Mission), the Mars 2020 spacecraft uses a guided entry, descent and landing system. The landing system of the Mars 2020 mission includes a parachute, a descent vehicle and an approach called "skycrane maneuver" to lower the rover from a rope to the surface during the last seconds before landing.

This type of landing system provides the ability to land a very large heavy rover on the surface of Mars in a more accurate landing area than was possible before Curiosity's landing. The Mars 2020 rover adds new entry, descent and landing (EDL) technologies, such as Terrain-Relative Navigation (TRN). Navigation relative to the terrain allows the rover to detect and avoid dangerous terrain by deviating around it during its descent through the Martian atmosphere. A microphone allows engineers to badyze entry, descent and landing. It could also capture the sounds of the rover at work, which would provide engineers with clues to the health and operations of the rover.

The Mars 2020 rover design is based primarily on engineering design for the Curiosity rover from Mars. This confidence in a proven system reduces the costs and risks of the mission. The rover's long-range mobility system allows it to travel on the surface of Mars at a distance of 3 to 12 miles (5 to 20 kilometers). The rover has a new and more capable wheel design, among other improvements. For the first time, the rover carries a drill to extract samples of rocks and Martian soil. Collect and store the cores in tubes on the Martian surface, using a strategy called "storage cache storage." Caching shows a new ability to rover to collect, store and preserve samples. Possibly it could pave the way for future missions that could collect the samples and return them to Earth for an intensive laboratory badysis.

The Mars 2020 rover helps prepare for future human exploration of Mars with a technology to extract oxygen from the Martian atmosphere. which is 96 percent carbon dioxide. This demonstration of new technology helps mission planners to test ways to utilize the natural resources of Mars to support human explorers and improve the designs of life support, transportation and other important systems for living and working on Mars.
