Mars climate change is a research area that focuses on studying the changes in the climate and atmosphere of Mars over time. Scientists are interested in understanding how Mars' climate has evolved and whether there are any indications of past or present conditions that could support life. This research involves analyzing data from spacecraft missions, such as NASA's Mars Rover and Mars Reconnaissance Orbiter, as well as data collected from telescopes and other observational tools. By studying Mars' climate change, scientists hope to gain insight into the planet's history and potential for habitability.
