NASA's Curiosity rover has begun a new phase of atmospheric analysis on Mars, focusing on the composition of the planet's thin air. The rover, which has been exploring Gale Crater since 2012, is using its Sample Analysis at Mars (SAM) instrument suite to study gases in the Martian atmosphere. This latest operation, spanning sols 4604 to 4606 (Mars' equivalent of Earth days), aims to deepen scientists' understanding of seasonal changes and atmospheric dynamics on the Red Planet.
Curiosity's SAM instrument will specifically measure isotopes of carbon and oxygen, which could reveal clues about Mars' climatic history and potential habitability. The data may also help explain how Mars lost much of its original atmosphere over billions of years. This atmospheric study coincides with the rover's ongoing geological investigations of Mount Sharp's sedimentary layers, which preserve a record of environmental changes.
According to NASA scientists, these measurements are particularly valuable as Mars approaches its southern winter solstice, when atmospheric conditions are most stable. The findings will contribute to ongoing research about planetary atmospheres and assist in preparations for future human exploration. The Curiosity team noted that while the rover continues to function well beyond its original two-year mission, each new dataset provides critical insights into Mars' evolving story.
