❓ Frequently Asked Questions
What is a Mars rover and what does it do?
A robotic vehicle that drives across Mars to study its geology, climate, and potential habitability, using onboard instruments and cameras.
Which mission first landed a rover on Mars and what was its name?
Mars Pathfinder (1997) carried the rover Sojourner, the first rover to roam Mars.
What is a major discovery from Mars rovers regarding water on Mars?
They found strong evidence that Mars once hosted liquid water and had habitable conditions in its ancient past, indicated by ancient river/lake features and water-related minerals.
What is the main goal of the Perseverance rover?
To search for signs of ancient life, collect and cache rock samples, and test new technologies for future sample-return missions.
