On October 29, 2018, the image of the Higheris camera on NASA’s Mars reconnaissance orbiter captures the gas and dust geyser in the spring in the south polar region of Mars. As the sun is elevated in the sky, the carbon dioxide accumulated in winter starts to heat a thick coating of ice and then turns to vapor. The sunlight enters through transparent ice and is absorbed at the base of the ice layer. The gas that is produced due to warming is saved from weaknesses in the snow and disappears as geyser.
Hirise, or high resolution imaging science experiment, is a powerful camera that takes photographs covering the vast areas of the Martian region, while able to see small features in the form of kitchen tables.
