Bengaluru, Sep 7: ISRO may have lost Chandrayaan-2's Vikram lander and rover Pragyan housed inside it, a senior official of the space agency associated with the unmanned moon mission said here Saturday.
Earlier in the day, contact from the lander to the ground stations was lost during its powered descent to the Lunar surface minutes before the planned touch-down.
"Vikram lander descent was as planned and normal performance was observed up to an altitude of 2.1 km.
Subsequently, the communications from the lander to ground stations was lost," ISRO chief K Sivan said.
"The data is being analysed," he added.
Speaking to PTI, a senior official closely associated with the mission, said later: "There is no communication with the lander.
It's as good as lost. There is no hope. Very, very difficult to re-establish contact".
The 1,471-kg lander of Chandrayaan-2 first Indian mission to explore the lunar terrain with home-grown technology -- is named Vikram after Dr Vikram A Sarabhai, the father of the Indian space programme.
The lander was designed to execute a soft landing on the lunar surface, and to function for one lunar day, which is equivalent to about 14 earth days.
Chandrayaan-2's 27-kg rover is a six-wheeled robotic vehicle named Pragyan, which translates to 'wisdom' in Sanskrit.
It's designed to travel up to 500 metres from the landing spot on the Moon and leverage solar energy for its functioning.
The lander carried three scientific payloads to conduct surface and subsurface science experiments, while the rover carried two payloads to enhance our understanding of the lunar surface, according to ISRO.
The mission life of the orbiter will be one year while that of the rover was to be one lunar day which is equal to 14 earth days.

India is proud of our scientists! They’ve given their best and have always made India proud. These are moments to be courageous, and courageous we will be!

Bengaluru (PTI): A day after a video of a man seen in a disoriented state went viral on social media with claims that he was under the influence of a so-called “zombie drug”, police on Friday arrested a 29-year-old employee of a private firm here for uploading the “misleading” video.
Hemanth, a resident of Vidyaranyapura, was issued a notice to join the inquiry, police said.
Learning that the police were looking for him, he posted an apology on social media. He was later taken into custody, a senior police officer said.
A case has been registered against him under Sections 353(2), relating to statements conducing to public mischief, including spreading false information or rumours that could incite public disorder, and Section 352, dealing with intentional insult with intent to provoke breach of peace, among others, under the Bharatiya Nyaya Sanhita, police added.
After Hemanth uploaded the video, it quickly went viral on Thursday.
Later, police clarified that the man shown in a disoriented state in the video had not consumed any narcotic or psychotropic substance.
He was subjected to a medical examination, and the report confirmed that there was no trace of narcotic substances, Bengaluru police said.
The police also urged the public not to spread unverified or misleading information on social media platforms, as such content can create unnecessary panic and harm individuals’ reputations.
The footage, which circulated widely on social media, showed the man standing motionless. People claimed he might be under the influence of a synthetic “zombie drug” and raised concerns about its availability in the city.
An inquiry revealed that the individual seen in the video had come to Bengaluru in search of a livelihood and had been residing there for the past three months, police said, adding that further investigation is ongoing.
The police warned that strict action will be taken against persons found spreading false information or rumours.
