Life on Mars could reach Earth by riding asteroid impact debris, new study suggests
SMRTR summary
Johns Hopkins researchers discovered that Deinococcus radiodurans, Earth's most resilient bacterium, can survive the crushing pressures of asteroid impacts that blast debris from Mars into space. The experiment showed over half the microbes survived pressures 30 times greater than Earth's deepest ocean depths, suggesting life could travel between planets on impact debris.
