Mars missions refer to various space exploration efforts aimed at studying the planet Mars. These missions have been conducted by several space agencies, including NASA, ESA (European Space Agency), and ISRO (Indian Space Research Organisation). They utilize orbiters, landers, and rovers to gather data about Mars' surface, atmosphere, and potential for past or present life. Notable missions include the Mars Rover Curiosity, which landed in 2012 and has been exploring the Gale Crater, and the Mars Perseverance Rover, which landed in 2021 to search for signs of ancient life. These missions help scientists understand Mars' geology and climate, paving the way for future human exploration.
