  • 5 min read

For Prelims: ISRO, NASA, MOM, Roscosmos, MOM-2, Gaganyaan, Chandrayaan-3 and Aditya – L1

For Mains: Reasons for the End of Mangalyan Mission

Why in News?

The Indian Space Research Organization (ISRO) confirmed that the Mars Orbiter craft has lost communication and is non-recoverable and the Mangalyaan mission has attained end-of-life.

What caused the End of MOM?

  • Because of propellant (fuel) exhaustion the desired altitude pointing could not be achieved for sustained power generation and it lost communication from the ground station.
  • Recently there were back-to-back eclipses including one that lasted seven-and-half hours because that satellite has consumed all the propellant on board.
    • As the satellite battery is designed to handle eclipse duration of only about one hour and 40 minutes, a longer eclipse would drain the battery beyond the safe limit.

What is MOM?

  • About:
    • The Rs 450 crore Mars Orbiter Mission was launched onboard PSLV-C25 on 5th November, 2013, and the MOM spacecraft was successfully inserted into the Martian orbit in September, 2014 in its first attempt.
    • Mangalyaan was India's first interplanetary mission.
    • The mission made India the first Asian country, and the fourth in the world after Roscosmos, NASA (National Aeronautics and Space Administration), and the European Space Agency, to get to the planet.
      • China referred to India's successful Mangalyaan as the "Pride of Asia".
  • Description:
    • It carried 850 kg of fuel and 5 science payloads including a Mars Color Camera (MCC) which it was using to study the Martian surface and atmosphere since entering orbit successfully.
      • The highly elliptical orbit geometry of MOM enabled MCC to take snapshots of the 'Full disc' of Mars at its farthest point and finer details from the closest point.
      • The MCC has produced more than 1000 images and published a Mars Atlas.
    • Other instruments are: Thermal Infrared Imaging Spectrometer (TIS), Methane Sensor for Mars (MSM), Mars Exospheric Neutral Composition Analyser (MENCA) and Lyman Alpha Photometer (LAP).
  • Objectives:
    • It was aimed at studying the Martian atmosphere.
    • To explore Martian surface features, mineralogy, morphology and atmosphere using indigenous scientific instruments.
    • A crucial objective of MOM was to develop technologies required in planning, designing, management and operations of an interplanetary mission.

What is the Future Indian Mars Mission?

  • ISRO came out with an 'Announcement of Opportunity' (AO) for future Mars Orbiter Mission (MOM-2) in 2016 but 'Gaganyaan', 'Chandrayaan-3' and 'Aditya - L1' projects are in the current priority list.
  • Mangalyaan-2 will only be an orbiter mission.
