Why would we explore Mars, the fourth planet from the Sun, and the next outward from the Earth? What is there for humankind?
Through a telescope, Mars' red light reveals few details: an orange round world splashed with gray; white poles; rarely obscured by clouds. Close up, Mars is stunning: clouds hovering above lava-draped volcanos; nearly endless chasms, their depths lost in mist; towering ice cliffs striped with red. Mars' past is laid bare in the landscape. Impact scars mark world-jarring collisions with asteroids, and deep-winding channels recall titanic floods. But robot eyes alone have seen these sights, and then only from orbit high above.
Direct human experience in space has fundamentally altered our perspective of humanity and our place in the universe. Humans have the ability to respond to the unexpected developments inherent in space travel and possess unique skills that enhance discoveries.we should explore mars,we should explore the possibilities of living on mars and we should explore it with people.in my opinion robots are not a good choice for doing it.
