A hydrothermal vent on the Mid-Atlantic Ridge. Hot, mineral-rich fluids are distributed throughout the ocean via the dispersion cloud, known as the plume. The photo was taken during the M190 research expedition with the MARUM-QUEST4000 remotely operated vehicle. The arm of the robot holds a temperature lance into the plume to measure the temperature there. Photo: MARUM – Center for Marine Environmental Sciences, University of Bremen.

#Enceladus’ subsurface ocean 🌊 has #hydrothermal vents on its seafloor. Enceladus’ ocean contains molecular hydrogen — which #NASA has called “candy for microbes” 🦠 — as well as other building blocks for life, Iike carbon dioxide and methane. It’s pretty similar to the conditions that allowed ocean life to propagate on early Earth. https://www.planetary.org/articles/where-are-the-ocean-worlds-in-our-solar-system

Chinese Researchers Discover Massive Hydrothermal System in Pacific Ocean, Teeming with Life

A team of Chinese scientists has discovered a massive, previously unknown hydrothermal system at the bottom of the Pacific Ocean. Located northeast of Papua New Guinea, the Kunlun system consists of 20 large craters, some of which are as large as 5,900 feet in diameter and 430 feet deep. These crate... [More info]

Earlier we saw a map of hydrothermal sites around Tharsis suggested by James Dohm. The combination of warmth and water seemed promising in the search for life (or past life). Here are more of them, suggested in 2 studies in 2005 and 2007. These are not tied to a specific mission but could guide site selection. The 'crater sites' combined impact-generated heat with signs of water and included Gale and Gusev craters (crater sites A and B).

Now... back to human missions.

#maps #mars #hydrothermal

A map of Mars in 2 hemispheres showing two sets of hydrothermal sites suggested in 2005 and 2007. Among them are impact crater sites in which impact-generated heat and water combine to form a potentially habitable environment. Among them are Gusev and Gale craters which hosted rovers (Gusev before the studies, Gale afterwards).

Life on Mars has always been a draw, so where should we look? 25 years ago a popular idea was hydrothermal sites. As the name suggests, they combine heat and water, so obvious candidates would be volcanic areas with evidence of water. James Dohm (then at U. Arizona) mapped two sets of them, shown on this map. 1998 sites were in Thaumasia where many channels indicate water. Sites in 2000 were more widely distributed around Tharsis. None of these have been visited yet.

Hydrothermal sites suitable for landing missions to search for evidence of life are shown on a map of the Tharsis region of Mars. One set is in Thaumasia at about 40 degrees south. Another set is scattered all around Tharsis. The idea is that heat from under this volcanic region meets water which is suggested by many small channels throughout the area. Water and warmth - sounds good for life, but of course we still have no idea if it ever happened.

"the crater it left behind in the #GulfOfMexico was a literal hotbed for life, enriching the overlying #ocean for at least 700,000 years... a #hydrothermal system created by the #asteroid impact may have helped marine life flourish at the impact site by generating and circulating nutrients in the crater environment."
