MOM enters Mars trajectory: ISRO

In a historic development, India’s first Mars mission- the Mars Orbiter Mission’s (MOM) spacecraft’s was propelled into the Mars Transfer Trajectory freeing it from the influence of Earth’s gravity. ISRO successfully conducted the Trans Mars Injection (TMI) operations to put MOM on course to the Red Planet with the help of spacecraft’s 440 Newton liquid engine which was fired for about 22 minutes providing a velocity increment of 648 metres/second to the spacecraft. With this, the Earth orbiting phase of the spacecraft ended and is now on path to Mars.

The spacecraft is being continuously monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with support from Indian Deep Space Network (IDSN) antennae at Byalalu.

About India’s Mars Orbiter Mission (MOM) ‘Mangalyan’:
  • The Mars Orbiter Mission (MOM) has been named ‘Mangalyan
  • Launched onboard PSLV C25 on November 5, 2013 at 14:38 hours from the first launch pad of Satish Dhawan Space Centre atSriharikota.
  • India’s first interplanetary mission to planet Mars with an orbiter craft designed to orbit Mars in an elliptical orbit.
  • It will reach Martian transfer trajectory in September 2014. Subsequently, it is planned to enter into a 372 km by 80000 km elliptical orbit around Mars.
Objectives of India’s Mars Orbiter Mission (MOM) ‘Mangalyan’:
  • To showcase India’s technological prowess to send a satellite to orbit around Mars and conduct important experiments such as looking for signs of life, take pictures of the red planet and study Martian environment.
  • To develop the technologies required for design, planning, management and operations of an interplanetary mission.
  • Design and realisation of a Mars orbiter with a capability to survive and perform Earth bound manoeuvres, cruise phase of 300 days, Mars orbit insertion or capture.
  • Deep space communication, navigation, mission planning and management.
  • Incorporate autonomous features to handle contingency situations.
  • Exploration of Mars surface features, morphology, mineralogy and Martian atmosphere by indigenous scientific instruments.
Key Payloads on PSLV C25:
  1. Lyman Alpha Photometer (LAP)
  2. Methane Sensor for Mars (MSM)
  3. Mars Exospheric Neutral Composition Analyser (MENCA)
  4. Mars Colour Camera (MCC)
  5. Thermal Infrared Imaging Spectrometre (TIS)
