Hopes fading on re-establishing link with lander Vikram: ISRO scientists

Chandrayaan-2’s 27-kg rover is a six-wheeled robotic vehicle named Pragyan, which translates to ‘wisdom’ in Sanskrit, and is housed inside the lander

ISRO is continuing its efforts to restore link with Chandrayaan-2’s lander ‘Vikram’, but experts say time is running out and possibility of re-establishing communication looks “less and less probable.” Chairman of Indian Space Research Organisation K Sivan said on Saturday that the space agency will try to establish link with the lander for 14 days.
After lander Vikram was located on the lunar surface by Chandrayaan-2‘s on-board cameras on Sunday, he reiterated that those efforts would continue. A senior official associated with the mission said, “Progressively… as time goes by… it’s difficult(to establish link).” However, with “right orientation” it can still generate power and recharge batteries with solar panels, he added.
“But it looks less and less probable, progressively,” the official said on condition of anonymity. Another top ISRO official said “hard-landing” of Vikram on the Lunar surface has made the task of linking again with it that much difficult as it may not have the “right orientation,” and may not have landed on its four legs.
“Impact shock may have caused damage to the lander,” he said. The lander was designed to execute a soft landing on the lunar surface, and to function for one lunarday, which is equivalent to about14earthdays. Contact from the lander to the ground stations was lost during its powered descent to the Lunar surface minutes before the planned touch-down in the early hours of Satuday…

Chandrayaan-2 is about to begin its final descent to pull off a historic soft landing on the lunar surface. The India’s second moon mission has gone through a long journey dotted with many events in close to 12 years since being conceived in 2007. Starting from Chandrayaan 1, here’s a list of all the major events that led Chandrayaan-2 to where it is today:
April 2003
Over 100 eminent Indian scientists in the fields of planetary and space sciences, Earth sciences, physics, chemistry, astronomy, astrophysics and engineering and communication sciences discuss and approve the Task Force recommendation to launch a probe to the moon.
August 15, 2003
Prime Minister Atal Bihari Vajpayee announces the Chandrayaan mission during his Independence Day speech.
November 2003
The government gives its approval for the moon mission.
October 22, 2008
Chandrayaan-1 launched successfully from Satish Dhawan Space Centre, Sriharikota using four-stage PSLV rocket.
November 26, 2008
The indigenous Terrain Mapping Camera, which was first activated on October 29, 2008, acquires images of peaks and craters. This comes as a surprise to Isro officials because the Moon consists mostly of craters….
