Recent volcanic activity and hydrothermal minerals on Mars

http://www.avcr.cz/en/media/news-archiv ... s-on-Mars/

Quote:
“The 400-metre high cones have also been interpreted as mud volcanoes. But we observed morphological details such as bulging of solidified lava caused by the injection of more recent lava beneath the hardened crust, as well as characteristic surface patterns identical to lava fields on Earth. This reinforces our assumption that we are looking at magmatic rock volcanism, and not liquid mud.”

Worries about spreading Earth microbes shouldn’t slow search for life on Mars

https://theconversation.com/worries-abo ... mars-84742

Quote:
We’d assume that any indigenous life on Mars should be much better adapted to Martian stresses than Earth life is, and therefore would outcompete any possible terrestrial newcomers. Microorganisms on Earth have evolved to thrive in challenging environments like salt crusts in the Atacama desert or hydrothermal vents on the deep ocean floor. In the same way, we can imagine any potential Martian biosphere would have experienced enormous evolutionary pressure during billions of years to become expert in inhabiting Mars’ today environments. The microorganisms hitchhiking on our spacecraft wouldn’t stand much of a chance against super-specialized Martians in their own territory.

Is Life Locked in Ice on Mars?

http://blogs.discovermagazine.com/d-bri ... -mars-ice/

Quote:
So how about some numbers? “Taking into account the intensity of radiation in the Mars regolith, the data obtained by us makes it possible to assume that hypothetical Mars ecosystems could be conserved in anabiotic state in the surface layer of regolith (protected from UV rays) for at least 1.3-2 million years, at a depth of two meters for no less than 3.3 million years, and at a depth of five meters for at least 20 million years,” Cheptsov said.

Research Shows That Earthworms Can Thrive Even in Mars Soil

But what about the martian regolith's perchlorates? The elevated radiation compared to Earth? Even in a greenhouse, it will be decidedly cooler than Earth's soil. In short, a big nothing hyped up for clicks.
