The Claim for a First insight of Viram Lander on Moon.CHANDRAYAAN- 2 is the second lunar exploration mission developed by the Indian Space Research Organisation (ISRO), after Chandrayaan-1. As of September 2019, it consists of a lunar orbiter, which included the Vikram lander, andPragyan -the lunar rover. All of which were developed in India. The main scientific objective of this mission was to map and study the variations in lunar surface composition, as well as the location and abundance of lunar water.Chandrayaan-2 Chandrayaan-2 composite (Tecnical Specifications Mission type-Lunar orbiter, Lander and RoverOperator Indian Space Research Organisation (ISRO)COSPAR ID2019-042ASATCAT no.44441Websitewww.isro.gov.in/chandrayaan2-home-0Mission duration-Orbiter: ~ 7 yearsVikram lander: 14 days (planned) ;[1][2]Achieved: 0 days (landing failure)Pragyan rover: 14 days (planned);[2]Achieved: 0 days (landing failure)Spacecraft properties Manufacturer:Indian Space Research Organisation (ISRO)Launch mass Combined (wet) : 3,850 kg(8,490 lb) [3][4][5]Combined (dry): 1,308 kg (2,884 lb)[6]Orbiter (wet): 2,379 kg (5,245 lb)[4][5]Orbiter (dry): 682 kg (1,504 lb)[6]Vikram lander (wet): 1,471 kg (3,243 lb)[4][5]Vikram lander (dry): 626 kg (1,380 lb)[6]Pragyan rover: 27 kg (60 lb)[4] [5] PowerOrbiter: 1 kW (1.3 hp)[7]Vikram lander: 650 W[8]Pragyan rover: 50 W[8] Start of Mission Launch date:22 July 2019, 14:43:12 IST (09:13:12 UTC)[9]Rocket- GSLV Mark III M1[10] [11]Launch site-Satish Dhawan Space Centre (Second Launch Pad )Agency- Indian Space Research Organisation (ISRO)Moon orbiter Orbital insertion: 20 August 2019, - 09:02 IST(03:32UTC)[12[13]Orbital parameters-Pericynthion altitude100 km (62 mi)[14] Apocynthion altitude100 km (62 mi)[14]Moon lander Space craft component Rover Landing date: 7 September 2019, 01:53 IST (failure)(6 September 2019, 20:23 UTC)[13][15]Landing site Lunar south pole (intended)Chandrayaan programme - Scheduled as-← Chandrayaan-1<-- Chandrayaan-2← Chandrayaan-3 (Under Process) The Chandrayaan-2 spacecraft was launched on its mission to the Moon from the second launch pad at the Satish Dhawan Space Centre at Andhra Pradesh on 22 July 2019 at 2.43 p.m. IST (09:13 UTC) by a GSLV Mark III M1. The craft reached the Moon's orbit on 20 August 2019 and began orbital positioning manoeuvres for the Landing of the Vikram lander at Moon Surface. The Lander and the Rover were scheduled to land on the near side of the Moon, in the south polar region at a latitude of about 70° South on 6 September 2019 and conduct scientific experiments for one lunar day, which approximates to two Earth weeks. A successful soft landing of the Lander would have made India the fourth country after the Soviet Union, United States and China to do so.However, the lander deviated from its intended trajectory while attempting to land on 6 September 2019, which caused a 'hard landing. According to a failure analysis report submitted to ISRO, the crash was caused by a software glitch. In the quest to locate the lost Lander, Two subsequent image sequences were acquired on October 14,15 and November 11, 2019 .The LROC team scoured the surrounding area in these new mosaics and found the impact site at 70.8810 degree South, 22.7840 degrees East, 834 m elevation and was supposed with associated debris field. The November 2019 mosaic had the best pixel scale 0.7 meter/ per pixel , With a better light condition . Though, no any claim since been made about the wellness of Vikram Lander. An effort is being made by (me) Mr Jagmohan saxena to find the whereabouts of the (lost ) Vikram Lander and it is supposed that the Pics of Vikram Lander found are exactly on the same Southpole Coordinates (near site) where it was intended to touch down for a soft landing. IT is -70.88087° Latitude and 24.26206° Longitude with a pixel size of 0.50m/px. The final Version of CONFIRMATION of location of Vikram Lander at moon is seek Officially with the launching agency ISRO.
