Mars Missions Timeline

Mars exploration has progressed from early flybys and orbiters to long-lived rovers, sophisticated landers and international orbital missions. Mars has been observed for thousands of years, but spacecraft transformed it from a point of light into a world that can be mapped and sampled.

Mars is a world where apparently simple questions often lead to larger scientific problems. Researchers combine spacecraft images, measurements from orbit, surface observations and laboratory analysis of Martian material to build explanations that can be tested. As with all planetary science, the strongest conclusions come from multiple observations that agree with one another.

The value of studying mars missions timeline is not limited to one isolated fact. Mars is a rocky planet with a long geological history, a thin atmosphere and evidence that its environment changed substantially over time. Individual observations become more useful when they are placed into that larger planetary context.
