NASA Scientist Answers: Is There Life on Mars?
Although there is no evidence of life on Mars yet, there are potentially habitable places on the planet, such as the deep subsurface, where organisms could live and be protected from radiation. NASA's Perseverance rover is collecting data that could help identify biosignatures of ancient microbial life. There is still a lot of Mars left to explore, and new instruments are being developed to help understand the planet's potential for habitability.
