The Red Planet lacks a source of carbon dioxide that could transform its thin, cold atmosphere into something resembling conditions on Earth.
New research suggests that active volcanoes on the Red Planet could have created an environment habitable to ancient microbes.
In this image from NASA’s Mars Reconnaissance Orbiter, a group of steeply inclined light-toned layers is bounded above and below by unconformities (sudden or irregular changes from one deposit to another) that indicate a “break” where erosion of pre-existing layers was taking place at a higher rate than deposition of new materials.
Mars can blame Jupiter for its small stature. The Red Planet may be much smaller than we expect because Jupiter’s gravity beat it up as it was forming.
Last week, NASA did something many have demanded it do since the Space Launch System was unveiled in 2011: Provide more details on how the agency will send humans to Mars.
Possibly a ‘Archaeological Site’ spotted in NASA “Global Mars Surveyor Mission” photo.
Scientists in Peru conducted experiments reminiscent of the 2015 Matt Damon film the Martian, creating similar conditions on Earth
Understanding the limits on what microbial life can endure is important for preventing contamination of the Red Planet with terrestrial microbes when our human and robotic explorers arrive.
