ISRO Found Chandrayaan-2 Vikram Lander Before NASA, Claims ISRO Chief

ISRO Found Chandrayaan-2 Vikram Lander Before NASA, Claims ISRO Chief

Sivan further said, "You can see on our website that we have already identified the crashed lander".

On Tuesday, NASA released an image taken by its Lunar Reconnaissance Orbiter (LRO) that showed the site of the spacecraft's impact (6 September in India and 7 September in the US) and associated debris field, with parts scattered over nearly two dozen locations spanning several kilometres.

Chennai: Shanmuga Subramanian, a 33-year-old engineer from Chennai, turned into an global celebrity overnight after the NASA on Tuesday acknowledged that he had given them the first clue leading to the discovery of the debris of Vikram lander on the moon. "All possible efforts are being made to establish communication with the lander".

On ISRO's web site, a press release on September 10 says, "Vikram lander has been positioned by the orbiter of Chandrayaan-2, however no communication with it but".

NASA said it was able to locate the debris after a tip-off by Shanmuga Subramanian, a 33-year-old mechanical engineer and app developer from Chennai.

Global carbon emissions set to grow more slowly in 2019, experts say
Coal use is plummeting in Europe and the United States because of cheaper natural gas and renewables, explained Jackson. It's simply working alongside fossil fuel sources to provide new energy, so carbon emissions aren't offset.


He acknowledged Vikram with partly burnt gas must possess had a mass of 700-800 kg (fresh weight changed into 1,471 kg), a lot like that of a sedan vehicle or a small airplane.

"Practically appreciate a small crater or dent". With this impact like jet crash on lunar regolith, a very fine dust of 0.5 m to 5-6 m thick covering of lunar surface, I expected a great upheaval in the first impact site, spreading around 10m or more across. Truly, the mud or debris also can jump up noteworthy bigger than on the earth, as lunar gravity is one sixth of that of the earth. And from ISRO's live images, I made out it would have stopped short of around 1 km from the landing spot so it eventually led to me searching around 2 sq km around the landing area.

India's Moon Lander mission abruptly gone wrong, as the Vikram lander and rover lost the contact with Chandrayan-2 Probe seconds before the soft landing on the lunar surface.

The Vikram Lander successfully separated from Chandrayaan-2 Orbiter on September 2. Before going public, they need to make 100 per cent sure that it is Vikram lander. Shanmuga spent hours in front of the computer comparing the two photos - one from December 2017 and the other from after ISRO lost contact with Vikram - and noticed some differences in the lunar surface. The reply came after 50 days when NASA credited him for the feat.
