If humans make it to Mars, here are the 8 best destinations to explore! ⬇️
, temperatures near both the north and south poles are so frigid that carbon dioxide condenses out of the atmosphere into ice, on the surface.
The process reverses in the summer, when the carbon dioxide sublimates back into the atmosphere. The carbon dioxide completely disappears in the northern hemisphere, leaving behind a water ice cap. But some of the carbon dioxide ice remains in the southern atmosphere. All of this ice movement has vast effects on theCuriosity rover
in 2012, Gale Crater is host to extensive evidence of past water. Curiosity stumbled upon a streambed within weeks of landing, and found more extensive evidence of water throughout its journey along the crater floor. Curiosity is now summiting a nearby volcano called Mount Sharp and looking at the geological features in each of its strata.
One of Curiosity's more exciting finds was discovering complex organic molecules in the region, on multiple occasions. Results from 2018 announced these organics. Simultaneous to the organics results, researchers announced the rover also found methane concentrations in the atmosphere change over the seasons. Methane is an element that can be produced by microbes, as well as geological phenomena, so it's unclear if that's a sign of life.
taking place hundreds of times over 500 million years. These eruptions would have warmed the Red Planet's climate as greenhouse gases from the volcanoes drifted into the atmosphere.Mars is host to strange features called recurring slope lineae, which tend to form on the sides of steep craters during warm weather. It's hard to figure out what these RSL are, though. Pictures shown here from Hale Crater show spots where spectroscopy picked up signs of hydration.
