Chandrayaan-1 was India's first lunar orbiter mission, launched in 2007-2008. It was designed to conduct high-resolution remote sensing of the lunar surface using visible, infrared, X-ray and gamma ray instruments over a planned 2-year operational life. The orbiter's objectives included producing a 3D topographical map of the moon and studying the distribution of minerals and chemical elements on the lunar surface. Chandrayaan-1 helped advance India's space science capabilities and achieved its mission goals before its operations concluded in 2009.

1. MOON
MISSION

2. Chardrayaan-1 is the
first Indian Mission to
the Moon devoted to
high-resolution remote
sensing of th e lunar
surface features in
visible, near infrared,
X-ray and low energy
gamma ray regions.

5. The mission is proposed to be a lunar polar
orbiter at an altitude of about 100 km and
is planned to be launched by 2007-2008
using indigenous spacecraft and launch
vehicle of ISRO. The mission is expected
to have an operational life of about 2
years.
MOON
MISSION

6. 1st stage
ISRO ’s PSLV will take a 1.5 m cuboid
Chandrayan-1 at a launch speed of
10 km/sec.
Built somewhat like the weather satellite
Kalpana, it will slow down to 8 km/sec. &
Join Kalpana almost on the same orbit to
Swim around earth first.
240 km
36,000 km

7. 240 km
36,000 km
The satellites liquid apogee motor will fire,
Pushing it out of earth’s magnetic clasp &
Take it to 3,86,000 km. On the road to the
Moon.
2nd
Stage
3,86,000 km

8. 3rd
stage
200 km
Solar Panel of the craft will open up
The orbit will be reduced to 200 km. & the craft will get some
rest
At a speed of about 1 km/ sec. Chandrayan will spend about two
weeks going round moon.

9. 100 Km.
Finally the the orbital altitude will be reduced to 100 km.
& there it will circle around for two years
Final stage

10. When Chandrayan is behind the moon
it will store data in memory. When it
Comes to our side they will be sent like
SMS service.

11. Carry out high resolution mapping
of topographic features in 3D.
Distribution of various minerals
and elemental chemical species
including radioactive nuclides
covering the entire lunar
surface using a set of remote
sensing payloads.
Realize the mission goal of
harnessing the science payloads,
lunar craft and the launch vehicle
with suitable ground support
system including DSN station,
integration, testing, launching &
achieving lunar orbit of ~100 km

12. Terrain Mapping Camera (TMC)
The purpose of this instrument
is to generate high - resolution
3-D cartographic map of the
moon using stereoscopic
cameras.
Hyper Spectral Imager (HySI)
Uses a wedge filter and an area
array detector to obtain the full
“spectrum information of the
target” by acquiring image data
for mineralogical apping.

13. Lunar Laser Ranging Instrument (LLRI)
The LLRI is used for providing ranging data
for determining the accurate altitude of the
spacecraft above the lunar surface.
X-ray Fluorescence Spectrometers
This payload consists of three parts:
Low Energy X-ray detector (LEX) to map
the abundance of light elements like Mg,
Al, Si, Ca, Ti and Fe.
Solar X-ray Monitor to
continuously measure the
fluxof solar X-rays.
High Energy X-ray/ gama-ray detector
(HEX) to map the distribution of high
atomic number elements over the lunar
surface such as 210Pb, 222Rn, U, Th.
