Chandrayaan-1 was India's first lunar exploration mission launched in 2008. It was an unmanned spacecraft launched using the PSLV C11 rocket. The mission aimed to conduct a chemical and mineralogical mapping of the lunar surface and study the moon's topography, mineralogy, elemental abundance, and lunar exosphere. The spacecraft carried high resolution cameras and spectrometers and completed over 3,400 orbits of the moon collecting extensive data before communication was lost in 2009. The mission was considered a success and helped further India's space capabilities.

4. Introduction
• CHANDRAYAAN mission was
India's “ first lunar exploration”.
• It was been launched by a
modified version of PSLV C11.
• It was an unmanned lunar exploration undertaken
by ISRO( Indian space research organization)
• It was launched on 22nd October 2008; 6:23 IST from
SATISH DHAWAN SPACE CENTRE , SRIHARIKOTA,
ANDHRA PRADESH.

5. Specifications
• After full integration, the Chandrayaan-1
spacecraft (left) is seen being loaded into
the 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.

6. 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.

7. •PSLV is a Polar Satellite Launch
Vehicle, which launched the
chandrayaan successfully in transfer
orbit.
•PSLV-C11 is the uprated version of
its standard configuration.
•Weighing 316 tonnes at lift-off,Uses
both solid and liquid propellants.
•Prefered launching vehicle of ISRO
with 13 consecutive flights

9. Objectives
Create a map of the Moon that will help us if
man finally builds a lunar base.
 It will search for water on the Moon, which
would be needed for human settlement there.
 Search for precious minerals which can be
mined in the future for the benefit of mankind.
Minerals supplies on earth are quickly coming
to an end !

10. Facts
• 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.

The second picture has been taken over the equatorial region of the Moon. This picture was taken
on November 13, 2008, by Chandrayaan-1’s TMC.

14. Loosing Radio Contact
• Chandrayaan-I completed
312 days in orbit
• It made nearly 3,400 orbits
around the moon
• Indian deep space network
(IDSN) noticed a number of
technical failures.
• But ISRO announced that the
mission was 90% completed

15. Award For Chandrayaan-1
The American institute of Aeronautics and
Astronautics(AIAA) had selected ISRO’s
Chandrayaan-1 mission as one of its annual
AIAA Space 2009 awards.
