Scientists generally believe that if there is life on Mars, they must be hidden in underground caves. The theory has been supported by NASA experts, andmedia recently explained the hypothesis in detail to Vlada Stamenkovic, a scientist at NASA’s Jet Propulsion Laboratory.
He said: The surface of Mars is a very oxidizing, radiation-intensive environment, liquid water for a long time is also unstable, so the surface of Mars is not suitable for life, if there is still life on Mars today, the existence of groundwater caves should be their only habitat.
Some scientists believe we should build robots that can explore Mars caves, but they are too expensive, and the U.S. Geological Survey has mapped more than 1,000 potential entrances to Mars caves.
NASA also plans to launch a new generation of Mars mission rovers later this year, which NASA says will not only look for traces of life on Mars, but also pave the way for future space exploration missions such as human landings on Mars.
