Share with friends and circles of friends with wechat scanning QR code < / P > < p > on August 13, although NASA's Mars rover perseverance is looking for signs of ancient life on the surface of Mars, the agency actually believes that life is more likely to be found in Martian caves than on the surface < p > to this end, NASA is cooperating with a number of contractors including Boston Dynamics to carry out a project called "biological and resource simulation survey in low light environment" (brain) to explore Martian like caves on earth, hoping that these experiences can be used for future space missions < p > fully automated robots like Boston Dynamics spot can help explore these caves. It is believed that these caves are hundreds of meters long, which makes it more difficult for the probe to communicate with the earth, and sometimes it is impossible to communicate at all < p > Figure 1: NASA is training the Boston Dynamics robot dog spot in the earth cave, hoping to help find life on Mars in the future < / P > < p > on earth, NASA has implanted its automation and artificial intelligence system Nebula into spot, hoping to help explore the moon, Mars and other places in the solar system in the future < p > Ali Agha, the research director of the project, said: "potential human exploration missions in the future can benefit from robots in many different ways. Especially before humans land at their destinations, robots can be sent to perform Pioneer missions to provide more information about their destinations. " < p > AGA also said: "robots can accompany astronauts during missions, help them scout specific terrain or perform logistics and many tasks, which can make astronauts' missions safer and more efficient." < p > Figure 2: fully automatic robots can help explore Martian caves. NASA has implanted its automation and artificial intelligence system Nebula into spot < / P > < p > in July this year, NASA's insight lander described the internal structure of Mars in detail and used data from Marsquakes to show the core, mantle and crust of Mars < p > according to NASA's website, with nebula, researchers believe that the robot brain can handle various task elements, including perception, environment, movement, system health and communication. For the body, the robot needs to have the functions of temperature management, shielding radiation and saving power and energy < p > AGA said: "spot is one of the most capable robots we have. It is amazing to see how it successfully responds to high-level commands from the robot brain and how it maintains stability in rugged and extreme terrain. In addition to our traditional wheeled rover, the ability to 'walk' is essential when dealing with no roads and uneven terrain. " < p > Figure 3: caves were discovered on Mars in 2007, and scientists speculated that there may be life in these caves < / P > < p > researchers first discovered caves on Mars in 2007, when they speculated that there may be life in these caves. Since then, researchers have been studying the underground lava pipes on the red planet and its satellites, including those in Pavonis Mons. Mount Pavonis is one of the largest volcanoes on Mars and may be used for human habitation in the future < p > a robot needs to be able to carry enough payload so that its eyes, ears and brain can help it navigate on Mars or satellites. In addition, the robot also needs to carry a necessary number of scientific instruments and can cross all kinds of terrain with "reasonable" stability, speed and endurance < p > AGA explained that spot is one of the few robots NASA is working with that can meet all three requirements. Therefore, implanting Nebula on spot can help break through the limits of exploring the unknown Martian environment < p > NASA's Jet Propulsion Laboratory (JPL) emphasized spot's "intelligence" on its website, pointing out that it can be used to discover microorganisms under the surface of Mars or life on icy celestial bodies such as Europa, Enceladus and Titan < p > AGA said that the next generation of robots may enter areas that traditional Mars rovers (such as perseverance or curiosity) cannot enter. In addition, due to the improvement of speed and crossing ability, future exploration missions can target destinations traditionally considered too far away from the landing area on Mars < p > in April this year, a study published by researchers at Brown University showed that life may still be multiplying in the dusty landscape of Mars. The researchers looked at the chemical composition of Martian rocks and determined that if they came into contact with water, they might support life similar to the microbial community on earth（ Small) < / P > < p >
