Challenges Faced

  1. Distance – Target was moving at a rapid pace around the sun and adding to that was unknown of venturing into the space.
  2. Communication – Owing to huge distance (upto 400 million kms), a communication system with low, medium and high gain antenna and other ground antennae was put in place to handle communication which took between 6 to 43 minutes for 2-way communication.
  3. Power – Demand of strong solar panels by the spacecraft. A solar panel was put in place to generate 840W of power in Martian orbit with 36 AH lithium ion attached onboard for power storage.
  4. Protection – Designing the spacecraft to avoid all the the thermal and radiation environments on en route to Mars.

 

Payloads onboard Spacecraft

  1. Mars Color Camera (MCC) – To capture images and composition of Mars, monitoring dynamic events and weather etc.
  2. Methane Sensors – To map the sources of methane in Martian environment.
  3. Lyman Alpha Photometer (LAP) – To study the escape process of upper atmosphere as well as water from Mars.
  4. Thermal Infrared Imaging Spectrometer – To map surface composition and mineralogy of Mars based on thermal emissions.
  5. Mars Exospheric Neutral Composition Analyzer (MENCA) – To analyze the neutral composition.
