For NASA, the real Mars landing is their next big space program. After all, since humans were sent to the moon, it has been almost 50 years since the humans still did not really set foot in the solar system. Other territories. Before sending astronauts to Mars, NASA must obtain more data to ensure safety. After all, there are indeed many disasters in the history of American aviation. No one dares to take it lightly.
In order to more clearly explore the situation of Mars, NASA intends to send a " robot physicist" to Mars to explore some of the inside of Mars. At present, NASA's announcement is in the spring of next year, and its specific work is to explore how the dark red color on the surface of Mars is formed, and the internal structure of Mars. It can be said that it will mark human cognition of the internal situation of Mars, from the previous speculation to the systematic, real exploration.

At present, such research is done on the earth by seismic waves, that is, the physical properties of the subsurface medium are judged based on the difference in data between the measured P wave and the S wave. Under this technology, humans have initially studied some data on the composition and thickness of the crust, mantle and core. Studying these data from Mars will help scientists to further compare the differences between Earth and Mars, so as to better judge whether Mars is suitable for life. At the same time, it is also possible to select some safe landing sites for astronauts who will land on Mars in the future, and avoid as much as possible the areas where the geological activities on Mars are more active.
According to current plans, the detector will be launched on March 4, 2016, landing on Mars on September 28, about six months later, and completing preliminary exploration missions in 2018. At present, NASA announced that the time to land on Mars is between 2020 and 2030. Perhaps after the "machine scholar" has completed the exploration, NASA will implement the plan to land on Mars.
