Deinococcus Radiodurans: Mars

Deinococcus Radiodurans: Mars

  • In a recent study, scientists imitated the intense ionising radiation on Mars and discovered that ancient bacteria may be able to endure considerably longer than previously thought near to the planet's surface.
  • The robust bacterium could live for 280 million years if it were buried, according to a new study, shattering the previous record. This implies that signs of life may still be dormant and hidden beneath Mars' surface.

With regards to Deinococcus radiodurans

  • Numerous terrestrial microbes demonstrated that they could be able to thrive on Mars, but one in particular, Deinococcus radiodurans, appeared to be especially well-suited to residing there.

  • The microbe was given the moniker "Conan the bacterium" by the researchers because it could withstand extremely high radiation levels while being frozen.
  • This implies that when the first samples from Mars return to Earth, researchers may even uncover microbes and their byproducts.
  • The research team exposed six distinct terrestrial bacteria and fungi under conditions resembling life on the red planet in order to determine whether any life forms might survive the extreme environmental conditions there.
  • They accomplished this by freezing the germs and bombarding them with protons and gamma rays.
