Two types of crewed Mars rovers are pressurized and unpressurizedunpressurized designs may have open seating for a crew in Mars space suits, and another style has a pressurized interior for people to work without a space suit. Pressurized rovers have been envisioned for short trips from a Mars base, or they may
Mars Exploration Program on Earth, could be used by microscopic life forms living under the Mars' surface. Life on Mars can also be searched for by finding signatures of past and present life or biosignatures. Relative carbon abundance and the location and forms that it can be found in can inform where and how life may have developed. Also, the presence of carbonate minerals, along with the fact that Mars' atmosphere is made up largely of carbon dioxide, would tell scientists that water may have been on the planet long enough to foster the development of life. Another goal of the MEP is
