  • Tiny groups of bacteria as thin as five sheets of paper survived outside the International Space Station for 3 years.
  • This finding suggests that bacteria in groups might be able to drift in space and spread life on planets.
  • Study authors estimate that 1,000-micrometer pellets of bacteria could survive 8 years in space, which could be enough to potentially reach Mars.
