Chandrayaan-1.
Chandrayaan-1 is India’s first mission to moon. It was launched on October 22, 2008 at 6.22 am and the name of Chandrayaan was derived from the Sanskrit word which means moon vehicle. It takes 5.5 days to reach the moon.
The Chandrayaan-1 is launched in the polar satellite launch vehicle [PSLV]. The PSLV will put the satellite into an elliptical orbit under the influence of earth gravity. The PSLV is modified to lift the 1,304 ton satellite and attain a highly elliptical orbit. The nearest point (Perigee) of this orbit will about 250km. The farthest point (Apogee) will be about 22,860km away from earth. The launch vehicle will have to achieve a velocity of about 2600km an hour to place the satellite into the transfer orbit. This will do in just over 18 minutes, or 1096 seconds to be exact. The total estimation for designing this Chandrayaan-1 is about 386 crores and is only about 5% of the money that is sanctioned by the government for space and researches. Hence Chandrayaan-1 is the lowest one when compared to the cost of satellites launched by other nations in the world.
The Chandrayaan mission will focus on the exploration of the south pole of the moon besides 3 dimensional mapping of the entire moonscape. The rim of shackleton crater is a location identified by the US space agency NASA to establish a possible lunar outpost by 2020. An advantage of location is the availability of sunlight for about 90% of the time. This means abundance of solar energy for power generation. A bigger attraction of location is the possibility of finding water in the dark areas of the poles such as the craters. NASA’s lunar prospectors had indicated the presence of water in the form of ice in the craters. ISRO may confirm the presence of water by the next year when data from instruments on board Chandrayaan-1 are analyzed.
The Chandrayaan-1 contain 11 payloads, the four would serve to detect water. The 6 payloads include the countries like America, Europe etc… and the 5 payloads were designed by ours.
The first stage of the vehicle together with its six strap-on booster’s carriers 320 tones of propellants. The 3rd stage also uses solid propellants while the second and fourth stages use liquid propellants. The space craft was moved to 83 meter tall vehicle assembly building [VAB].
An important is the moon impact probe [MIP]. The moon impact probe [MIP] which has pride of place among the 11 instruments on board Chandrayaan-1. The MIP which weights 29kgs and sits like a hat on top of Chandrayaan-1. After Chandrayaan-1 reaches the lunar orbit at an altitude of 100kms, ISRO will give command to it to re-orient and eject the MIP, which has a motor on board. The motor will fire for two seconds to reduce the MIP’s velocity to 75 meters a second. As the MIP descends to the moon’s surface, its video camera will take pictures of the lunar surface. The MIP’s altimeter will measure its altitude from the moon every second of its journey towards the moon. The 3rd instrument, a mass spectrometer will sense the moon’s atmospheric constituents as it falling and crashes the moon.
The main reason for launching Chandrayaan-1 at this instant of time revels the fact that India a nation containing 120 crores of people is also able to work in all technical aspects related to satellite communications and in future we also have rights and get membership on the international lunar network.
We also feel very much proud that a tamilan named Mayilsamy Annadurai is leading the entire team of Chandrayaan-1. If Chandrayaan-1 gets succeeded then our next operation is searching of Helium-3 which is an important raw material for power generation. Researches have been carried out on moon confirms that there are some 50 lakh tones of Helium-3 that gets hidden under the rocks and there is a competition among the nations in bringing the raw material to earth as the net content of Helium available on earth is only about some 15 tones and is so highly unstable.
Finally if we are able to bring Helium-3 among these tough competitions then we are able to meet the power demands faced by our nation as only some 5 tones are required by our nation to meet the energy demands for about one year.
