Mars Orbiter Mission 2 (MOM-2) also known as Mangalyaan-2 is planned to launch by 2025. This interplanetary mission is planned to launch from Vikram Sarabhai Space Centre launch pad with onboarding a orbiter. Scientists are working on the various rovers, landers and orbiters for utmost utilization of the payload capacity. The mission is to enter the inner mars orbit for better observation and perceive more information.


GSLV MARC III which are more powerful from PSLV systems used during MOM, will be used to leave earth’s atmosphere. This is a three stage step rocket system with each rocket equipped with own engine and propellent. This plan is to reach the orbital speed of the planet where the orbiter will be placed.

Initial work by MOM in gathering information about mars like Martian atmosphere, mineralogy, topography, morphology helps us is planning, developing, designing and management for interplanetary missions. For MOM- the lift off pay load was 1,337.2 kg. There were various surface imaging sensors like

  • Thermal Infrared Imaging Spectrometer serve as active remote sensing process.
  • Mars Color Camera MCC, This camera sensor setup is used to collect surface features and composition of Martian surface. The images are used for change detection in the Martian surface like weather condition, surface changes, atmospheric dust storms etc.
  • Mars Exospheric Neutral Composition Analyser (MENCA): This is quadrupole mass analyser used to analyse the neutral composition of the particles in the range of 1-300 atomic mass unit.
  • Lyman Alpha Photometer: This instrument is used to measures the relative abundance of deuterium(stable nuclide of hydrogen) and hydrogen from Lyman-alpha emissions in the upper atmosphere. Measuring the deuterium/hydrogen ratio will allow an estimation of the amount of water loss to outer space.
Various Engineering test, propulsion test and payload capacity tests have been completed for MOM-2
