The Mars Orbiter Mission is a spacecraft that was sent to explore and study Mars, the closest planet to Earth. It was launched from Earth in November 2013 and arrived at Mars in September 2014. When it is in Mars's orbit, the spacecraft collects information about the planet including pictures and measurements about the atmosphere, surface, and environment. It also looks for any evidence of water or other possible signs of life. This information is then sent back to scientists on Earth so they can study Mars and better understand our solar system.
