Mars Orbiter Mission completes four years in orbit: Know about India’s first interplanetary mission Mangalyaan

India’s maiden interplanetary mission – the Mars Orbiter Mission (MOM) – has completed four years orbiting the red planet, according to ISRO.

This mission made India the first country to enter the red planet’s orbit on its first attempt.

The satellite sent back some stunning images of the Red Planet to commemorate the big day.

What is the Mars Orbiter Mission?

  • The mission, launched by the Indian Space Research Organisation (ISRO) on November 5, 2013, by PSLV-C25, successfully placed itself into Martian orbit on September 24, 2014, in its first attempt

  • Although the designed mission life of MOM was six months, the satellite has continued to beam back science data from Mars for the past four years

  • MOM is built with full autonomy to take care of itself for long periods without any ground intervention. The spacecraft came out of communication ‘blackout’ during this period

  • MOM spacecraft experienced the ‘whiteout’ geometry from May 18 to May 30, 2016

  • A ‘whiteout’ occurs when the Earth is between the sun and Mars and too much solar radiation may make it impossible to communicate with the Earth
  • The maximum duration of ‘whiteout’ is around 14 days

Mars Orbiter Mission features

1. Mars’s two moons — Phobos and Deimos — have been captured up close by the orbiter’s Mars Colour Camera.

2. The Mars Colour Camera has acquired over 980 images so far. The mission has also helped scientists successfully prepare a global atlas of Mars.

3. MOM is the only Martian artificial satellite which could image the full disc of Mars in one view frame and also image the far side of the Martian moon Deimos.

Data that the orbiter has collected from its first two years has already been processed and made public in an online database.

Data from year 3 was also added to the database on Wednesday, 26 September.
