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? 46 + 47 + 48 += Experiment Data = 49 + 50 +|=(% style="width: 156px;" %)Date|=(% style="width: 1683px;" %)Files 51 +|(% style="width:156px" %)[[2021-10-15>>https://mission.oewf.org/archive_downloads/amadee20/TUMBLEWEED-JRP/2021-10-15/]]|(% style="width:1683px" %)((( 52 +pictures of wring issues 53 +))) 54 +|(% style="width:156px" %)[[2021-10-17>>https://mission.oewf.org/archive_downloads/amadee20/TUMBLEWEED-JRP/2021-10-17]]|(% style="width:1683px" %)repair pics 55 +|(% style="width:156px" %)[[2021-10-18>>https://mission.oewf.org/archive_downloads/amadee20/TUMBLEWEED-JRP/2021-10-18/]]|(% style="width:1683px" %)troubleshooting pics 56 +|(% style="width:156px" %)[[2021-10-19>>https://mission.oewf.org/archive_downloads/amadee20/TUMBLEWEED-JRP/2021-10-19]]|(% style="width:1683px" %)Pictures and Video 57 +|(% style="width:156px" %)[[2021-10-20>>https://mission.oewf.org/archive_downloads/amadee20/TUMBLEWEED-JRP/2021-10-20]]|(% style="width:1683px" %)2xVideo, 5 pics, POI.md 58 +|(% style="width:156px" %)[[2021-10-22>>https://mission.oewf.org/archive_downloads/amadee20/TUMBLEWEED-JRP/2021-10-22/]]|(% style="width:1683px" %)7 pictures 59 +|(% style="width:156px" %)[[2021-10-24>>https://mission.oewf.org/archive_downloads/amadee20/TUMBLEWEED-JRP/2021-10-24]]|(% style="width:1683px" %)2 videos 60 +|(% style="width:156px" %)[[2021-10-29>>https://mission.oewf.org/archive_downloads/amadee20/TUMBLEWEED-JRP/2021-10-29]]|(% style="width:1683px" %)1 video 61 + 62 +
