Atmosphinder investigates the geomorphic processes in the south polar region of Mars of seasonal jet eruptions and the important role it plays in the atmospheric system. The experimental prototype is a 7 ft tall rover with 2.4 m2 of sails to catch the wind. As the wind pushes the sails, the hoops begin to turn about a central bearing that is stabilized by reaction wheels. The electronics payload is suspended in the roll cage. The electronics are used to control sail trimming, precision drive module, sensors, reaction wheels, and lights. The prototype will be tested at the Mars Desert Research Station with Crew 261 in May 2023 to conduct three science objectives.

Science Objectives:

  1. Autonomous navigation control of rover as propelled by varying wind speed and direction
  2. Conduct a visual survey of the terrain, zonal boundaries, troughs, and rocks
  3. Collect environmental sensor payload data



Custom circuit board was created, named Hemisphere v1.0, based on all the previous work and lessons learned from Bowie's electronics.
