Figure 3. Views of Aram Chaos region. a) Mars Express High Resolution Stereo Camera (HRSC) image with compositional units from CRISM marking polyhydrated sulfates (PHS) in blue, monohydrated sulfates (MHS) in green, and ferric hydroxysulfate in red (N is towards the right). b) HiRISE view of region in yellow box where all three sulfate types are in close proximity (north is up).
Ferric Hydroxysulphate mineral offers clues about Mars's past [via SETI Inst. & NASA] 🧪🔴🌑🔮
"warmest #geothermal #sources likely sat beneath the sites where ferric #hydroxysulfate appears today, although more may lie buried under monohydrated sulfates"
