Overview
Advanced view of Mars
Mars is a cold, dry terrestrial planet with a thin carbon-dioxide atmosphere, giant volcanoes, deep canyons, polar ice caps, widespread impact terrain, and abundant evidence that liquid water was more important in its ancient past. Its present environment preserves a record of major climate and geological change.
Mars is central to studies of planetary climate evolution, volcanic history, atmospheric escape, habitability, and the preservation of biosignatures. It also provides a practical target for testing robotic exploration and future human operations.

supported · checked Sep 22, 2026Orbiters, landers, and rovers have mapped channels, deltas, layered sediments, hydrated minerals, volcanic landforms, and polar deposits.
supported · checked Sep 22, 2026Mars's lower gravity and lack of active plate tectonics allowed volcanoes to remain over long-lived mantle sources and grow to extreme size.
