#GS3 #Science&Technology 

The Mars Orbiter Mission ( also called Mangalyaan launched by the Indian Space Research Organisation (ISRO) has been orbiting Mars since September 24, 2014. While it was to built to study the red planet & accumulate date for about three years it continues to do so till date.

  • In the latest from the space probe, a coloured image of Phobos has been captured by the orbiter.
  • The image was taken on July 1 by MOM using the onboard Colour Camera (MCC) onboard.
  • Phobos is the closest and biggest moon of Mars. This image was taken on 1st July when MOM was at a distance of about 7,200 km from Mars and at 4,200 km from Phobos.
  • The Spatial resolution of the image is 210 m. This is a composite image generated from 6 MCC frames and has been colour corrected by ISRO.



What is Phobos?

  • Phobos is the innermost & the bigger one in comparison to Deimos the other moon orbiting mars. Both these moons were discovered in 1877 by American astronomer Asaph Hall.
  • Phobos is smaller when compared to the moon orbiting earth & is an irregularly shaped object.
  • "Phobos is largely believed to be made up of carbonaceous chondrites. The violent phase that Phobos has encountered is seen in the large section gouged out from a past collision (Stickney crater) and bouncing ejecta. Stickney, the largest crater on Phobos along with the other craters (Shklovsky, Roche & Grildrig) are also seen in this image," said ISRO in a statement
