Mars Astrobiology Explorer-Cacher is a NASA mission being planned for 2024. The goal of this mission is to look for signs of life on Mars, like bacteria or other organisms. The mission will use a special kind of "robot" called a rover to explore the Red Planet. The rover will carry special equipment that can look for evidence of astrobiology, which are things like rocks, gases, and soil that may have been produced by living organisms. The rover will also be able to collect samples of the Martian environment so that scientists can study them in their labs back on Earth. This mission is important because it could help to answer questions about whether or not living things once existed or still exist on Mars.
