Bengaluru: According to ISRO Lander Vikram in located and intact in one piece on lunar surface. It bring out all hope to regain contact. The Indian Space Research Organisation continued to make all-out efforts to establish link with Chandrayaan 2’s ‘Vikram’ lander, now lying on the lunar surface after a hard-landing.
Vikram, with rover ‘Pragyan’ housed inside it, hit the lunar surface after communication with the ground-stations was lost during its final descent, just 2.1 km above the lunar surface, in the early hours of Saturday.
“It had a hard-landing very close to the planned (touch-down) site as per the images sent by the on-board camera of the orbiter. The lander is there as a single piece,not broken into pieces. It’s in a tilted position,” an ISRO official associated with the mission claimed today.
“We are making all-out efforts to see whether communication can be re-established with the lander,” the official said.
Chandrayaan 2 comprises an orbiter, lander (Vikram) and rover (Pragyan). The mission life of the lander and rover is one Lunar day, which is equal to 14 earth days.
ISRO Chairman K Sivan had said on Saturday that the space agency would try to restore link with the lander for 14 days, and reiterated the resolve on Sunday after the orbiter’s camera spotted it on the Lunar surface.
According to an ISRO official, unless and until everything is intact, it’s very difficult to re-establish contact. Only if all systems function, then only communication can be restored.
“I will rate it (restoring link) as good,” another senior official of the space agency said, raising hope that lander springing to life again is not ruled out. “But there are limitations. We have experience of recovering spacecraft in geostationary orbit. But here, that kind of operational flexibility is not there. Already it’s lying on the surface of the Moon, and we cannot reorient it. Vital thing is antennas will have to be pointed towards the ground station or the orbiter. Such operation is extremely difficult. At the same time, chances are good and we will have to keep our fingers crossed,” the official said.
The official said the lander generating power is not an issue, as it has “solar panels all around it” and it also has “internal batteries” which “are not used much.” Vikram carried three payloads Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere (RAMBHA),Chandra’s Surface Thermo-physical Experiment (ChaSTE) and Instrument for Lunar Seismic Activity (ILSA)
