High Quality Content by WIKIPEDIA articles! The Mars Exploration Program (MEP) is a long-term effort to explore the planet Mars, funded and led by the U.S. space agency, National Aeronautics and Space Administration (NASA). Formed in 1993, MEP has made use of orbital spacecraft, landers, and rovers to explore the possibilities of life on Mars, as well as the planet`s climate and natural resources. The program is managed by NASA`s Science Mission Directorate by Doug McCuistion of the Planetary Science Division. As a result of 40% cuts to NASA`s budget for fiscal year 2013, the Mars Program Planning Group (MPPG) was formed to help reformulate the MEP, bringing together leaders of NASA`s technology, science, human operations, and science missions.
