ISRO continues efforts to restore link with 'Vikram'

Bengaluru, Sept 9: Not losing hope, the Indian Space Research Organisation continued to make all-out efforts to establish a 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 September 7.

"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 on Monday.

"We are making all-out efforts to see whether communication can be re-established with the lander," the official said.

"An ISRO team is the on the job at ISROTelemetry, Tracking and Command Network (ISTRAC) here."

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 a link with the lander for 14 days, and reiterated the resolve on Sunday after the orbiter's camera spotted it on the Lunar surface.

An ISRO official said: "Unless and until everything is intact (lander), it's very difficult (to re-establish contact). Chances are less. Only if it had soft-landing, and if all systems functioned, then only communication can be restored. Things are bleak as of now."

"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 (which had lost contact) in geostationary orbit. But here (in the case of Vikram), 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 point towards the ground station or the orbiter. Such an 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).

New Delhi, Jun 1: The Directorate General of Civil Aviation (DGCA) on Monday asked airlines to allot seats in flights in such a manner that middle seats are kept vacant to the extent possible.

However, if a flyer has been allotted the middle seat due to a high passenger load "then additional protective equipment like the wrap-around gown of the Ministry of Textile approved standards" must be provided to that passenger in addition to three-layered face mask and face shield, said the DGCA order, which has been accessed by news agency.

India resumed its domestic passenger flights from May 25 after a gap of two months due to the coronavirus-triggered lockdown. International commercial passenger flights continue to remain suspended in the country.
