| 31 | Tumbleweed is the concept of a spherical rover to be deployed on Mars. They are designed to be spheres of a | ||
| 32 | diameter of 5 m equator-wards by Martian winds. One Tumbleweed consists of a sturdy aluminum/composite | ||
| 33 | outer frame and sails arranged to provide optimal air resistance. Solar cells on the sails provide power. Sensors | ||
| 34 | and electronics are attached to the outer frame. The first Tumbleweed prototype was already participating in | ||
| 35 | the AMADEE-18 mission. The research questions for the AMADEE-20 experiment can be summarized as: | ||
| 36 | |||
| 37 | 1) What is the performance of the solar cells perform under operational conditions? Specifically, what is | ||
| 38 | the effect of the constantly changing illumination angle caused by the rover’s movement | ||
| 39 | and different times of day? | ||
| 40 | 2) What is the distribution of abrasion on the Tumbleweed’s structure? Surface abrasion is | ||
| 41 | expected to be one of the main factors limiting the structural lifespan of a Tumbleweed | ||
| 42 | Rover. The aim is to find out more about the rate and distribution of this abrasion. The | ||
| 43 | test shall be conducted in sandy as well as increasingly rocky environment. | ||
| 44 | 3) How does the Tumbleweed’s speed and direction of movement vary under different | ||
| 45 | wind conditions? | ||
