   1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...

   Nov 27, 2018 · The Changing Ice Cap of Mars. Photojournal Note: This caption was corrected by the HiRISE science team on Nov. 30, 2018. A story of changes at the South Pole of Mars is told by its icy deposits. Remnants of a formerly more extensive deposit composed of dry ice form what is known as the south polar residual cap.

   May 18, 2023 · The north polar region of Mars, pictured on the left, has an ice-rich polar cap (the quasi-circular white area at center) and is approximately 1,000 km (621 miles) across. The south polar cap of Mars from left to right is about 420 km (260 mi) across. The above right photo was taken in summer.

   How much water does Mars lose in the polar cap ice?

   • In March 2015, a team of scientists published results showing that the polar cap ice is about eight times as enriched with deuterium as water in Earth's oceans. This means that Mars has lost a volume of water 6.5 times as large as that stored in today's polar caps.
