This has been “ground-truthed” from Mars Science Laboratory CHEMIN1 announced the close similarity between Mars soils and the tephra materials on the lower slopes of Mauna Kea2 (where the CheMin instrument was field tested at PISCES in 2008). The 2012 Joint NASA/CSA Analog Field test successfully operated the JUNO II rover at two analog sites3. Analog Sites: Test site 1 was at 11,500 feet eleva- tion on the south slope of Mauna Kea volcano near the terminus of the ancient glaciers in an area dubbed “Apollo Valley”. Varied loose rock and lava outcrops along with slope variability proved an operational chal- lenge. Test site 2 was at 9,500 feet elevation with more gentle slopes with a deeper loose tephra more similar to dusty open plains and dune terrain. Traction testing: Traverses across each of these sites were performed with mission simulation objectives and waypoints, along with path selection algorithms. References: [1] Vaniman, D. et.al.
