Kuongorora kwakaitwa nePhoenix lander kwakaratidza kuti ivhu reMars rine pH yepakati ye7.7, uye rine 0.6% yemunyu perchlorate. Iyi ndiyo yakanyanya kuwanda uye inoita kuti ivhu reMars rive chepfu (onawo chepfu yevhu reMars). Mitsetse yakajairika muMars uye mitsva inowanzoonekwa pamakomo akasimba emakoronga, makoronga, nemipata. Mitsetse yacho yakatanga yakasviba uye inozojeka nekukura kwemitsetse. Inogona kutanga munzvimbo diki, yobva yapararira kwemazana emamita. Yakaonekwa ichitevera micheto yematombo uye zvimwe zvipingamupinyi munzira yavo.
kuti iwo matema ari pasi pevhu akafukidzwa pashure pemakomba eguruva rakajeka kana kuti madhemoni eguruva
