  1. Rover Design Trey Chunn

  2. Purpose of the rover • Determine whether life ever arose on Mars. • Characterize the climate of Mars. • Characterize the geology of Mars. • Prepare for human exploration.

  3. Distance from earth • On the opposite end of the scale, Mars and Earth can be 401 million km (249 million miles). The average distance between the two is 225 million km.

  4. Temperature extremes • In the winter it can get to minus 195 degrees F. In the summer it can be 70 degrees F. At night temperature can get to minus 100 degrees F.

  5. Gravity • 3.711 m/s^2

  6. atmosphere • The atmosphere of Mars is less than 1% of Earths, so it does not protect the planet from the suns radiation nor does it do much to retain heat at the surface, It consists of 95% carbon Dioxide, 3 % Nitrogen, 1.6% Argon, and the remainder is trance amounts of Oxygen, Water Vapor, and other gases.

  7. Potential dangers • Radiation • Meteorites • Physical Health • Mental Health • Landing • Distance from Earth

  8. Additional information • Engineers at NASAs Jet Propulsion Laboratory designed the rover to roll over obstacles up to 25 inches high and to travel about 660 feet per day the rovers power comes from a multi-mission radioisotope thermoelectric generator, which produces electricity from the heat of plutonium-238’s radioactive decay.

  9. Additional information • NASA officials said the parachute would need to withstand 65,000 ibs to break the spacecraft’s fall to the surface. Under the parachute, the rover let go of the bottom of its heat shield so that it could get a radar fix on the surface and figure out its altitude. The parachute could only slow the rover to 200 mph, far too fast for landing. To solve this problem, engineers designed the assembly to cut off the parachute, and use rockets for the final part of the landing sequence.

  10. Additional information • The rover has a 7-foot arm to pick up samples from the surface and cook them inside the rover, sniffing the gasses that come out of there and analyzing them for clues as to how the rocks and soil formed. It can drill into each of these blocks and place a sample into its oven to measure its composition. Researchers will then see if organics appear that were not supposed to be in the block. If so, scientists will likely determine these are organisms hitchhiking from Earth. The rover is equipped with high resolution cameras surrounding the rover to take pictures as it moves, providing visual information that can be compared to environments on Earth.
