Some Extremophiles Could Survive an Asteroid Impact on Mars, and the Dangerous Journey to Earth

Millions of craters of all sizes help define the Martian surface and tell a tale of millions of impacts. We know that some Mars rock has reached Earth after being blasted into space by an impact. New research shows that at least one type of extremophile can survive the impact, and the hazardous journey to another world. Image Credit: NASA/JPL/Arizona State University, R. Luk

Panspermia is the idea that life was spread from world to world somehow. New research shows that one type of Earthly extremophile can survive the extremely high pressure from asteroid impacts on Mars, be blasted into space, and maybe even survive the journey to Earth.
