The document summarizes India's first lunar exploration mission, Chandrayaan-1. It provides details on the mission objectives, payload instruments, key events and accomplishments of the mission. Chandrayaan-1 was launched in 2008 and successfully studied the moon's topography and mineral composition using onboard instruments over its lifetime of 312 days in lunar orbit. The mission helped map the lunar surface and confirmed the presence of water ice and other minerals on the moon. It established India as the fifth nation to place a spacecraft in lunar orbit.

6.  The main objective was to carry out
scientific studies and to conduct high-
resolution mapping of topographic features
in 3D,distribution of various minerals and
chemical species such as radioactive
nuclides that cover the surface of the
moon.
 To Impact a sub-satellite ( Moon Impact
Probe -MIP ) on the surface on the Moon as
a fore-runner to future soft landing missions.

7.  Search for surface or
sub-surface water-
ice on the Moon,
specially at lunar
poles.
 Another objective
was to harness
several science
payloads, lunar craft
and the launch
vehicle with suitable
ground support
system.

8.  After full integration, the
Chandrayaan-1 spacecraft (left) is

Thermovac Chamber (right)
Mass
 1380 kg at launch, 675 kg at lunar
orbit, and 523 kg after releasing the
impactor.
Dimensions
 Cuboid in shape of approximately
1.5 m.
Communications
 X band, 0.7 m diameter parabolic
antenna for payload data
transmission. The Telemetry, Tracking
& Command (TTC) communication
operates in S band frequency.

9. Power
 The spacecraft was mainly powered by its solar array, which
included one solar panel covering a total area of 2.15 x 1.8
m generating 700 W of power, which was stored in a 36 A·h
Lithium-ion battery.
Propulsion
 The spacecraft used a bipropellant integrated propulsion
system to reach lunar orbit as well as orbit and altitude
maintenance while orbiting the Moon.
Navigation and Control
 The craft was 3-axis stabilized with two star sensors, gyros and
four reaction wheels.

13.  CHANDRAYAAN -1 was sent to moon in a series
of orbit increasing man oeuvres around the
earth as opposed to the launching of craft on
a direct trajectory to moon.
 Chandrayaan -1 successfully completed the
lunar orbit insertion operation on 8th Nov 2008,
with this India became the fifth nation to put
vehicle in lunar orbit.
 The MIP landed on lunar surface on 14th Nov
2008, which kept on sending information to the
mother satellite.
 The M3 retrieved the presence of iron and also
changes in rock and mineral composition.

14.  ISRO claims that the landing sites of the
APOLLO moon mission have been
mapped
 The craft completed 3000 orbits
acquiring 70,000 images of lunar surface
, which was quite a record.
 ISRO officials estimated that more than
40,000 images were sent in 75 days.
 On 26th Nov 2008, TMC acquired images
of peaks and craters on the surface.
 On 25th March 2009, Chandrayaan
beamed back the first image of earth.

15.  Chandrayaan-I
completed 312 days in
orbit
 It made nearly 3,400

 Indian deep space
network (IDSN) noticed
a number of technical
failures.
 But ISRO announced
that the mission was
