Named after the Roman god of war, it is often referred to as the "Red Planet" [1] [2] because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere , having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth .
The architecture involved multiple missions launching from Earth to Mars to collect the samples, and then conducting the first rocket launch from the surface of another planet to return the ...
