6. Benefits of VSF to institutions
 Meet the Scientist sessions at your institution
 either in person or
 through Webinars.
 Popular science talks at your institution
 Visit of students to Science laboratories in the
region.
 Science related competitions.
 Do it yourself - simple experiments to understand
scientific concepts

7. MARS ORBITER
INSERTION

11. Why Mission to Mars?
Similarities with Earth
 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

12. Mars is like EARTH
 Large river valleys
 ‘Super’ grand canyon

13. Mars is like EARTH
 Volcanoes

14. Mars is like EARTH
 Climate range similar to Earth
 Sky and clouds, dust storms

15. To 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.

17. The satellite structure is of aluminium and composite fibre
reinforced plastic (CFRP) sandwich construction

19. The 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).

20. Electric 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.
Liquid 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.
The 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.

21. The 15 kg scientific payload
consists of five instruments:
LAP Lyman-Alpha Photometer 1.97 kg
MSM Methane Sensor For Mars 2.94 kg
MENCA Mars Exospheric Neutral Composition Analyser 3.56 kg
TIS Thermal Infrared Imaging Spectrometer 3.20 kg
MCC Mars Colour Camera 1.27 kg

23. Methane Sensor
