Chandrayaan-1 

#GS3 #Science&Technology 

ISRO’s maiden mission to the Moon (Chandrayaan-1) has sent images which show that Moon may be rusting along the poles. 

  • The sign of this finding is that even though the surface of the Moon is known to have iron – rich rocks, it is not known for the presence of water and oxygen, which are the two elements needed to interact with iron to create rust.     
  • Scientists at the National Aeronautics and Space Administration (NASA) say that this could be because the Earth’s own atmosphere is lending a helping hand which, in other words, means that the Earth’s atmosphere could be protecting the Moon as well. 
  • Thus, the Chandrayaan-1 Moon data indicates that the Moon’s poles are home to water, this is what the scientists are trying to decipher.
