Chandrayaan-2 rover intact? Isro looking into new Nasa images
BENGALURU: Nearly 10 months after Isro’s failed attempt to soft land Vikram, the lander on Chandrayaan-2 mission that was carrying a rover (Pragyan), new images from Nasa have rekindled interest in the mission.
Shanmuga Subramanian, a techie from Chennai who had identified Vikram’s debris using Nasa images last year has now sent emails to the Indian space agency, claiming that the new set of images released by Nasa in May show Pragyan and even a track that indicates that the rover may have moved a few meters.
Isro chairman K Sivan, confirming this, told TOI: “We’ve heard nothing from Nasa so far on the matter. But yes, the person who had identified Vikram debris earlier has sent us an email about this. Our specialists are looking into the matter and we cannot say anything at this juncture.”
The November 2019 images from Nasa’s Lunar Reconnaissance Orbiter (LRO) showed the debris of Vikram lander. Given that Moon’s polar region is not always well lit and the lander was in a shallow depth of 2ms from the surface, the rover was not visible from the November images.
“Going by the January 4 images (made public in May), however, I think Pragyan may be intact and that it has rolled out a few metres from the lander. We need to know how the rover may have moved and I hope Isro is able to confirm this,” Shanmuga Subramanian told STOI.
He further postulated that Pragyan rolled out acting on some of the blind commands sent by Isro’s ground command that was relayed by Vikram. However, Isro, which lost communication with Vikram in the early hours of September 7, 2019 has not been able to re-establish contact since.
The agency, however, had tried communicating with Vikram for multiple days after the hard-landing. One explanation to the rover’s movement on Moon’s surface, if the finding is accurate, would be that Vikram, which lost communication with the ground station, may have sent some commands to Pragyan which Isro never learnt about.
“We will have to analyse and see what may have happened. There is nothing concrete now,” Sivan said.

Send Pappu to find out what happened
My India, my pride! My ISRO, my pride! My Modiji, my pride! Bharat Mata Ki Jay!
Some anti Modi Government will bark now.. This success cannot happen at all...
There is nothing to be ashamed of if a mission fails. And there is nothing to be proud of either. I know there will be disappoints and frustrations do set it.We have to keep trying. It is a matter for scientists and technocrats. Let us hope their next endeavour succeeds.

Where is buffalo Fawad Hussain, Pakistan Science and Technology minister who mocked about Indias Chandrayaan Vikram Lander and Rover?
If somebody really loves India, he can't hate B.J.P. as there is no option.

ISRO, the pride of India
What are ISRO engineers doing. Why can't they find..Why are they relying on some freelance enthusiast.
See the power of Modi. Due to his presence at ISRO the rover is intact.
An ordinary man without any support structure alerting ISRO based on Nasa images ? Looks like ISRO scientists simply sitting and monthly getting . Recruit that man right away to use the sophisticated technology that ISRO have.
This is still as surprising to me as it was 10 months ago. One guy has more enthusiasm and intellect than the entire ISRO.
its a closed chapter no use wasting time.. concentrate on next probe...
Failure doesnt mean success denied, its success delayed! Thats it!
Awaiting Good News
reservation policy in educational institutions and government jobs has spoiled and rendered institution like ISRO, DRDO, RBI useless!!
预留制已经把ISRO, DRDO（印度国防研究与发展组织）, RBI（印度储备银行）这样的机构毁了!!
Master stroke by Modi. He had advised ISRO when to launch and land the rover. That's why it is saved.
He looked at the clouds and used sewer energy to resurrect the rover from death Hail Modi!!
Wasted taxpayers money by unpad chaiwala
It was a brave effort by ISRO ... but there is no need to drag on anymore ..
Useless/fake news. The batteries are long dead and no point in talking about the failed lander. Better Isro work on Chandrayana-3 instead of looking into what an amateur tipped off to the agency.
thanks to congress we have ISRO .
Send Pappu, he loves to ride the rover.

so success rate moves from 98% to 99% now
Would be miracle if we get Vikram alive ...
