MOON MISSION

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.

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 launchvehicle of ISRO. The mission is expected to have an operational life of about 2 years.

MOONMISSION

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 satelliteKalpana, 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

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 theMoon.

2nd Stage

3,86,000 km

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 twoweeks going round moon.

100 Km.

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

Final stage

When Chandrayan is behind the moonit will store data in memory. When it Comes to our side they will be sent likeSMS service.

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

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.

Lunar Laser Ranging Instrument (LLRI) The LLRI is used for providing ranging datafor 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.
