SAM (Sample Analysis at Mars)

SAM (Sample Analysis at Mars) is a scientific instrument aboard NASA's Curiosity rover that analyzes Martian soil, rocks, and atmospheric gases. It helps scientists understand the planet’s composition, history, and whether conditions ever supported life. SAM warms samples to release gases, then identifies their chemical makeup using sophisticated detectors. This process provides clues about Mars’ geology, climate, and potential habitability, aiding our quest to learn about the planet’s past and whether microbial life might have existed there.
