• Some Extremophiles Could Survive an Asteroid Impact on Mars, and the Dangerous Journey to Earth
  2026-03-03

• NASA study finds ancient life could survive 50 million years in Martian ice
  2026-02-25
  Mars’ frozen ice caps may be time capsules for ancient life. Lab experiments show that key building blocks of proteins can survive tens of millions of years in pure ice, even under relentless cosmic radiation. Ice mixed with Martian-like soil, however, destroys organic material far more quickly. The findings point ...
