STUDENT’S FORUM
MARS ORBITER INSERTION
भारतीय अंतरिरक्ष अनुसंधान संगठन, The Indian Space Research Organization (ISRO) is the
space agency of India, with an objective to
advance space technology and use its applications for national benefit.
MANGALYAAN
Spacecraft
Mars also has elliptical orbit like Earth and similar - Surface conditions Similar geology Availability of water? Atmosphere (thin) Polar ice caps Magnetic field Natural conditions similar to arctic and Antarctic
Why Mission to Mars?Similarities with Earth
Mars is like EARTH
Large river valleys ‘Super’ grand canyon
Mars is like EARTH Volcanoes
Mars is like EARTH Climate range similar to Earth Sky and clouds, dust storms
Mars Orbiter Mission is India's first interplanetary mission to Mars with a craft designed to orbit Mars in an elliptical orbit.The Mission is primarily technological mission considering the critical mission operations and stringent requirements on propulsion and other bus systems of spacecraft.
Mangalyaan ( Orbit )
Mission ObjectivesTo develop the technologies required for 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 / capture, and on-orbit phase around Mars.
Deep space communication, navigation, mission planning and management.
Scientific Objectives are - Exploration of Mars surface features, morphology, mineralogy and Martian atmosphere by indigenous scientific instruments.
The satellite structure is of aluminium and composite fibre reinforced plastic (CFRP) sandwich construction

SPACECRAFT DETAILSMassThe lift-off mass was 1,350 kg, including 852 kg of propellant mass.Cuboid in shape of approximately 1.5 m (4 feet 11 inches).
Dimensions
PowerElectric power is generated by three solar array panels of 1.8 m × 1.4 m each 7.56 Sqm, for a maximum of 840 W generation in Martian orbit. Electricity is stored in a 36 Ah Li-ion battery.PropulsionLiquid fuel engine of 440 N thrust is used for orbit raising and insertion in Martian orbit. The orbiter also has eight 22 N thrusters for attitude control or orientation.CommunicationsThe antenna array consists of a low-gain antenna, a medium-gain antenna and a high-gain antenna. The High-gain antenna system is based on a single 2.2-metre reflector illuminated by a feed at S-band. It is used to transmit and receive the telemetry, tracking, commanding and data to and from the Indian Deep Space Network.
