4.  Design and realisation of a Mars orbiter with a
capability to perform Earth bound maneuvers,
cruise phase of 300 days, Mars orbit insertion /
capture, and on-orbit phase around Mars.
 Deep space communication, navigation, mission
planning and management.
 Incorporate autonomous features to handle
contingency situations.
 The secondary objectives are scientific, and include
the study of Mars surface features, morphology,
mineralogy and the Martian atmosphere.

6.  Dozens of spacecraft,
including orbiters,
landers, and rovers, have
been sent to Mars by the
Soviet Union, the United
States, Europe, and Japan
to study the planet's
surface, climate, and
geology. As of 2008, the
price of transporting
material from the surface
of Earth to the surface of
Mars is approximately
US$309,000 per kilogram.

7.  launch will place from sriharikota and the Mars
Orbiter will be placed into Earth orbit, then six
engine firings will raise that orbit to one with an
apogee of 215,000 km and a perigee of 600 km,
where it will remain for about 25 days.
 A final firing in 30 November 2013 will send
MOM onto an interplanetary trajectory.
 Mars orbit insertion is planned for 21 September
2014 and would allow the spacecraft to enter a
highly elliptical orbit of 372 km x 80,000 km
around Mars.

8.  The Launch Vehicle - PSLV-C25 will
inject the Spacecraft into an Elliptical
Parking Orbit with a perigee of 250 km
and an apogee of 23,500 km.
 With six Liquid Engine firing, the
spacecraft is gradually maneuvered
into a hyperbolic trajectory with which
it escapes from the Earth’s Sphere of
Influence (SOI) and arrives at the
Mars Sphere of Influence.
 When spacecraft reaches nearest
pointof Mars (Peri-apsis), it is
maneuvered in to an elliptical orbit
around Mars by firing the Liquid
Engine. The spacecraft then moves
around the Mars in an orbitwith Peri-
apsis of 366 km an Apo-apsis of about
80000 km.

10.  The Polar Satellite Launch
Vehicle commonly known by
its abbreviation PSLV, is an
expendable launch system
developed and operated by
the Indian Space Research
Organization (ISRO). It was
developed to allow India to
launch its Indian Remote
Sensing (IRS) satellites into
sun synchronous orbits

14. PHASES OF MOM:
1. GEO CENTRIC PHASE:
STAGE 1 – STAGE 6
2. HELIO CENTRIC
PHASE: STAGE 7
3. MARTIAN
PHASE: STAGE 8

15. 1. Geo Centric Phase
The spacecraft is injected into an
Elliptic Parking Orbit by the
launcher. With six main engine
burns, the spacecraft is gradually
maneuvered into a departure
hyperbolic trajectory with which it
escapes from the Earth’s Sphere
of Influence (SOI) with Earth’s
orbital velocity + V boost.
2. Helio Centric Phase
The spacecraft leaves Earth
in a direction tangential to
Earth’s orbit and encounters
Mars tangentially to its orbit.
The flight path is roughly one
half of an ellipse around sun.
3. Martian Phase
The spacecraft arrives at
the Mars Sphere of
Influence (around 573473
km from the surface of
Mars) in a hyperbolic
trajectory. At the time the
spacecraft reaches the
closest approach to Mars
(Periapsis)

16. Mass
The lift-off mass was 1,350 kg , including
852 kg of propellant mass.
Dimensions
Cuboid in shape of approximately 1.5 m .
Power
Electric power is generated by three solar
array panels of 1.8 × 1.4 m each. Electricity
is stored in a 36 Ah Li-ion battery.
Propulsion
Liquid fuel engine of 440 N thrust is used for
orbit raising and insertion in Martian orbit,
and 8 numbers of 22 N thrusters are used
for attitude control .
Communications
Two 230 W TWTAs and two coherent
transponders. The antenna array consists of
a low-gain antenna, a medium-gain
antenna and a high-gain antenna.

20.  The Indian Deep Space Network will
perform navigation and tracking
operations of this mission, and
NASA's Deep Space Network will
provide support services during the
non-visible period of the Indian
Deep Space Network. The signals
from the orbiter take as much as 20
min to reach earth
 Also some of the ships positioned in
south pacific ocean will also track
and coordinate the spacecraft

21.  The government of India approved the project on 3
August 2012,after the Indian Space Research
Organization completed 1.25 billion (US$19 million)
of required studies for the orbiter. The total project
cost may be up to 4.54 billion (US$69 million).

24.  Communications with Mangalyaan to get blocked for 15 days in
June
 India's Mangalyaan mission will face a crucial period in June
when the sun will block out all communications with the ground
for 15 days, former Indian Space Research Organisation (ISRO)
chief Dr K Radhakrishnan has said. Dr Radhakrishnan made the
remarks at the Indian Science Congress and said, "If we could
regain control over the craft after that period, that would be one
more major achievement."
 According to a Times of India report, that this will be longest
break in communication with Mangalyaan, since the Mars Orbiter
was launched in November 2013. During the blackout phase the
orbiter will be "in an autonomous mode."
 The TOI report quoted MoM project director Subbiah Arunan as
saying that the blackout would be from 8 to 22 June because the
Sun will come between Earth and Mars. Arunan also said that in
May 2016, the Earth would come between Mars and Sun, leading
to another loss of communications for about a fortnight.

25. o The second mission to Mars could be between 2018-
2020, but may not be similar to the Orbiter Mission
launched last year, ISRO chief K Radhakrishnan said on
Wednesday.
 "MOM is not an end, but a beginining of our next
scientific mission. The next mission to Mars may happen
between 2018 to 2020. It may necessarily not be an
Orbiter Mission like MOM. We need to get feedback
from the scientific community on what kind of project
would this be," he said.
 The ISRO chief was speaking at a book launch of
'Reaching for the stars: India's journey to Mars and
Beyond' authored by eminient science journalist Pallava
Bagla and Subhadra Menon.

26. HERE ARE REASONS WHY INDIA’S MARS
ORBITER MISSION (MOM) IS JUST AMAZING :
 The Mangalyaan mission cost India $73 million (~Rs.450 crores) which is
even cheaper than an eight lane bridge in Mumbai which cost $340
million.
 It is less than the budget of film “Gravity” which was about $105 million
and about one-tenth of what the US has spent on MAVEN, making it
undoubtedly the most cost-effective inter-planetary space mission to
have ever been undertaken anywhere in the world!
 In real terms, when distributed over the population of 1.2 billion, every
Indian has contributed Rs.4 per towards the mission.
 Mangalyaan will observe the environment of Mars and look for various
elements like methane (marsh gas), which is a possible indicator of life. It
will also look for Deuterium-Hydroden ratio and other neutral constants.
 The orbiter weighs 1,350-kg, which is even less than the weight of an
average sports utility vehicle
 The manufacturing of Mangalyaan took 15 months while NASA took five
years to complete MAVEN.

27.  Certain features on Mars are similar to the
features of Earth.
 The features on Earth are known to have been
caused by the existence of water in those locations.
 Most scientists now believe that these features
on Mars are evidence that water has existed on
Mars in the past & may, in fact, still exist below the
surface today.
