Chandrayan 2

 We have know that about chandrayan 2 the mission was launched to the moon from the second launch pad at satish Dhawan space centre. on 22^nd  July by a Geosynchronous satellite launch vechile Mark lll (GSLV MK III)  with an approximate lift-off mass of 3,850 kg on Sri harikota Island. As of June 2019, the mission has allocated cost rs 978 crore (approximately US $141 milligan). Which includes rs 603 crore for space segment and rs 375 ccrore as launch Coast on GSLV MK III.

What happend with chandrayan are follows date by date:

22^nd July - date of launch

24^th  July - first orbit raising maneuver

25^th july - second orbit raising maneuver

29^th July - third orbit raising maneuver

2^nd Aug - fourth orbit raising maneuver

6^th aug - fifth orbit raising maneuver

13^th Aug - trans lunar injection

20^th aug - lunar orbit insertion

first lunar bound maneuver

21^st aug - second lunar bound maneuver

28^th aug - third lunar bound maneuver

30^th aug -  fourth lunar bound maneuver

2^nd sept - vikram separation

3^rd Sept - first & second orbit burn

6^th Sept  - power descent and

               Telemetry lost before the automated landing at about 2.1 km above the surface.

7^th sept - pragyan rover deployments.

So, it has been happened with the mission chandrayan 2.

Chandrayan 2 stack was initially put in an earth parking orbit of 170 km perigee and 40,400 km ago gee by the launch vechile. 

The mission's lander is called vikram, who is widely regarded as the founder of the Indian space programme. Engineering models of the lander began undergoing ground and aerial tests in late october 2016,in challekere in the chitradurga District of karnataka.

ISRO created roughly 10 craters on the surface to help assess the ability of the lander's sensors to select a landing site.

Feature of vikram lander:

• Dimensions :- 2.54 × 2 ×1.2 m.
• Grosslift-off :- 1,471 kg
• Propllent mass :- 845 kg
• Dry mass :- 625 kg
• Power generation capability :- 650 w
• Mission duration <= 14 days (one lunar day).

Finally, chandrayan 2 better than expected apogeas a result of the cryogenic upper stage being burned to depletion, which later eliminated the need for one of the apogee raising burns during the geocentric phase of missions. This also resulted in the saving of around 40 kg fuel on board the space craft.
