Mars is the fourth planet from our Sun in the Solar System. Out of the various planets and moons in our Solar System, Mars perhaps bears the most similarity to Earth, featuring an atmosphere, polar ice caps, and remnants of tectonic activity on the planet’s surface. Mars has fascinated both astronomers and the general public for years, and has been the subject of countless movies and fiction works. Currently, several nations in the world are planning to send missions to Mars for exploration, and NASA’s Spirit Rover recently ended a 6 year exploration of the surface after becoming trapped in sand.
