Description
How habitable might an Exo-Mars be? It's a complex question but one that NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission can help answer.
To receive the same amount of starlight as Mars receives from our Sun, a planet orbiting an M-type red dwarf would have to be positioned much closer to its star than Mercury is to the Sun.
