Do you think there is life on Mars?
What kind of missions have been sent to Mars to look for signs of life?
There have been many missions to Mars over the years, including NASA's Mars rovers and orbiters from multiple space agencies. These missions have studied the planet's geology, atmosphere, and potential for habitability. The next planned mission is NASA's Mars 2020 rover, which will search for signs of past microbial life on the planet.
