Surface Rovers
Athlete• Unload, setup,
and transfer habitat
• Setup natural radiation barrier using regolith
• Gather samples and assist the crew upon arrival.
Crewed Rovers
• Capacity of 2 (emergency 4)
• Temporary habitat when working
• Suit Ports allows astronauts to perform EVA’s without risk of contamination
MSL
• Mars Science Laboratory
• Drill into hills and the surface
• Gathers small samples
• Conducts simple analysis

Crewed Rovers• Speed ranges from 5 to 10
km/h.• 30 degree maximum incline.• Holds 4 crew members for
emergency ( Only 2 total crew members per mission).
• Suit ports allows astronauts to enter spacesuits without risk of contamination.
• Rover wheels move “crab like”- zero turning radius.
• Energy storage requirement- 375 kw *h.– 50.5 kw *h per hour for 8
hours.
Robotic Rovers• Two robotic rovers will be used, the MSL(Mars Science
Laboratory) and the Athlete • Robotic rover will perform tests, gather samples, and set
up the habitat– Athlete will unload, transport, and setup the habitat. Along with
gathering and placing regolith as radiation protection. After setup the athlete will gather samples along with assisting the crew upon arrival.
– MSL will drill into hills, the ground, and valleys. Along with gathering small samples and simple analysis.
Radiation Protection• Working area dose rate is 17 Rem/yr
• Dose estimate in rovers (191 hr) is 429 mRemwith 5 cm H2O and 3 cm Polyethylene shielding
• Dose estimate in space suits (46 hr)180 mRem
• Total Dose Estimate While Working on Martian Surface is 609 mRem
