The study conducted by Scientist was published in the journal Frontiers in Microbiology that some microbes that are found on Planet Earth might temporarily survive on the Mars.

  • This study is significant for the success of future MARS missions by the countries.
  • The endurance of the microorganisms was tested by the researchers from NASA (National Aeronautics and Space Administration) and German Aerospace Center (GAC).
  • It was tested by launching them into stratosphere which represents some the key conditions of MARS.
  • New way to expose bacteria and fungi on Mars-like conditions has been tested by using a scientific balloon to carry the experimental equipment up to stratosphere.
  • During the trip it was found that, some microbes particularly the spores from black mold fungus, were able to survive even when they were exposed to high ultraviolet radiation.

Mars (Red Planet)

  • The Red Planet is the second-smallest planet in the solar system. The planet carries the name of Roman god of war.
  • The Planet is also called as the Red Planet because of presence of iron oxide on Mars’s surface. Iron Oxide provides reddish appearance.
  • It has a thin atmosphere. Some of the surface features resembles the impact craters of Moon, and deserts, valleys, & polar ice caps of Earth.
  • The Days and seasons are similar to Earth because its rotational period and tilt of the rotational axis are similar to that of Earth.
  • The Red Planet is also a site of Olympus Mons. Olympus Mons is the largest volcano and highest known mountain on any planet.
  • Mars is also the home to Valles Marineris which is the largest canyons in Solar System.
  • The Red Planet has two natural moons named Phobos and Deimos.
  • Mariner 4 was the first spacecraft launched by NASA in the year 1964 to Red Planet.


The second major layer of Earth’s atmosphere lies in between the troposphere and mesosphere. It is the stratified (layered) in temperature. The warmer layers are at height while the cooler layers close to Earth. Ozone Layer is also a part of this layer of atmosphere.
