The chandrayaan

        The chandrayaan-2

Hello, friend's Have you ever heard about chandrayaan? By this, what the first word comes in your mind? As I guess it is the moon that is now coming in your mind. So, we are discussing Chandrayaan-2, But before discussing chandrayaan-2.I  want to summarize the chandrayaan-1.

Chandrayaan-1

Chandrayaan-1 was the first Indian lunar investigation in the chandrayaan program . It was launched by the ISRO as we know The Indian space research organization on 22nd October 2008.

Work of chandrayaan mission

Nowadays we often heard about chandrayaan but we don't know about the chandrayaan mission. So, we need to know what is chandrayaan?It is the Program of ISRO( Indian space research organisation ) under which the ISRO chandrayaan space craft Investigate about the Moon and send the report about moon to ISRO.

What was the chandrayaan -1?

Chandrayaan-1 was the first program of the chandrayaan mission.

Chandrayaan-1 launched on 22nd October 2008.  On the chandrayaan-1 403 crore, rupees spent. Its weight was 1380 Kg. It was on 312 days' mission of chandrayaan. It took the 3400 rounds of the moon and find the ice on the north pole of the moon and also find Water on the moon.

Chandrayaan-2

Chandrayaan-2 is India's second lunar investigation mission after chandrayaan-1 developed by the ISRO.The chandrayaan-2 was launched on 22nd July 2019 at 2:43 pm to the moon by the GSLV(MK III) spacecraft.

The dispatch of chandrayaan-2 was initially planned for 14 July 2019. But was canceled because of a specialized issue. The commencement was solidified at - 56 minutes 24 seconds.

Launch window

The launch window is a fixed time in which a particular vehicle must be launched to reach its intended target . If any spacecraft takes time more than the launch window so, there is a probability to bump into any planet when on 14th July chandrayaan-2  planned to launch that day ISRO had 10 minutes launch window. But on the 22nd July 2019, ISRO had only 1-minute launch window. It means this chandrayaan-2 was launched in the one-minute launch window.

Schedule of chandrayaan-2

Chandrayaan-2 will take rounds of the earth until 16 days and move towards the moon to moving towards the moon chandrayaan-2 Maximum speed will be 10 km p/sec  and the minimum speed is 3 km p/sec.

 

Parts of chandrayaan-2

Chandrayaan-2 has  three parts.

1.Orbiter:- It is the part of the chandrayaan-2. its weight  is  2,379 kg At the time of launch, the chandrayaan-2 orbiter will be capable to communicate with Indian deep space network(IDSN).The mission life of orbiter is 1 year.

2. Lander(Vikram):-Lander(Vikram) weight is 1,471 kg .It is intended to work for one lunar day, which is equal to around 14 earth days. Vikram can communicate with IDSN as well as Rover and orbiter. The lander is intended to execute a soft landing on the lunar surface.

3.Rover(pragyan):- Rover weight is 27 kg. It is the six-wheeled robotic vehicle which is named so Pragyan. The "Pragyan" word took from the word "Gyan" which comes from Sanskrit. It can travel up to 500 m. Its mission life is also for 1 lunar day equal to 14 earth days. It can only communicate with Lander. It is operated by artificial intelligence.

After 15 days chandrayaan-2 will move from the earth orbit towards to moon and enter in the moon orbit. Before  4 days of landing Lander(Vikram ) and Rover(Pragyan) will check the lunar south pole. After checking Lander will scan the lunar surface. Then the door will open of the Lander (Vikram) and Rover(Pragyan) will come out. Rover(Pragyan ) will take 4 hours to land on lunar surface. Rover (Pragyan) will take 1 lunar day round. Rover(Pragyan )
has 2 payloads through which we can get know about lunar surface.

It is one year mission.India is the first country to land on the south lunar surface. India is the fourth country to landing the spacecraft on lunar surface.

Thankyou
