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).

The total number of positive cases reached 4,789 on Tuesday, the 14th day of lockdown.

According to the latest update of the Health Ministry, there are 4,312 active cases, 352 persons have been cured or discharged (one migrated) and 124 have died.

Maharashtra has the largest number of positive cases at 868 and also accounts for the largest number of deaths at 48. Tamil Nadu has 621 confirmed cases.

"This strategy is producing positive results, especially in Agra, Gautam Buddh Nagar, Pathanamthitta, Bhilwara and East Delhi," he said.

Aggarwal said that a recent study by the Indian Council of Medical Research (ICMR) has shown that a person infected with coronavirus can infect 406 others in just 30 days if he does not follow the lockdown and social distancing norms.

He said no decision has been taken on extending the lockdown and urged against any speculation.

He said latest technology was being used for management of COVID-19 and there was real-time tracking of ambulances.

The official said the dedicated facilities for COVID-19 are divided into three parts -- COVID Care Centre, Dedicated COVID Health Centre and Dedicated COVID Hospitals.

He said that COVID Care Centres were for treating mild, very mild and likely to be COVID-19 patients. Hostels, hotels, school, and stadium can be used for this. "We have asked states to map it with COVID Care Hospitals and COVID Health Centre so that patients can be shifted if needed," he said.

The official said that COVID Health Centres were for treating COVID-19 patients of clinically moderate level of seriousness. "For this, fully functional hospitals will be used. A dedicated block of a fully functional hospital can also be used for this. The hospitals must have beds with oxygen support," he said.

Aggarwal said that dedicated COVID Hospitals were meant for severe and critical cases and these must be fully-equipped with ICUs and ventilators.
New coronavirus cases were reported on Tuesday from several states including Maharashtra, Madhya Pradesh, West Bengal, and Tamil Nadu.

The Ministry of Environment, Forest and Climate Change has issued an advisory about containing coronavirus in national parks, sanctuaries and tiger reserves in view of the spread of COVID-19 and a report about tiger being infected in New York.

New Delhi, Mar 20: The government on Thursday said one Indian who tested positive for coronavirus has died in Iran while the other citizens infected with the disease are being provided treatment and taken care of by the Iranian government.

Noting that the virus tends to be more fatal for those whose immunity levels are low, a senior MEA official said the deceased, an elderly person, belonged to the vulnerable age group and had health-related complications.

The death was not because of lack of medical attention or care, he said.

"We have evacuated 590 people from Iran where the situation is very severe. The Indians infected with coronavirus in Iran have been segregated and taken care of very well by the government there. We believe they will recover and we will bring them back," the MEA official said, adding that 201 Indians were evacuated from Iran on Wednesday.

The official said closely knit families required some persuasion and counselling during the process of segregation to prevent the spread of the contagion.

The Indian ambassador and other officials explained the consequences of infected people not being separated from their families and were successful to a large extent in segregating the positive cases from the negative ones, he said.

"Some pilgrims and students are still there and our embassy and mission are in control (of the situation)," the official said.
