Hello People of Earth, I will talk you about the Mars Odyssey.

Its mission includes making the first global map of the amount and distribution of many chemical elements and minerals that make up the Martian surface. It successfully completed its primary science mission from February 2002 through August 2004.

Mars Odyssey has been circling the Red Planet since 2001. It broke a record in 2010 for being the longest-serving piece of machinery to work at Mars, and it continues to operate at the Red Planet.

Mars Odyssey has been making discoveries of its own such as finding extensive water ice under the surface of Mars but it also plays an important part in the ever-growing network of Martian rovers. It has served as a communications relay for the now-dead Spirit rover and current Opportunity and Curiosity rovers. Odyssey is also expected to assist with the 2020 European-Russian ExoMars rover mission.
