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 16: Despite Prime Minister Narendra Modi led government’s attempt to downplay the border dispute with China, matters have heated up unprecedentedly along the Line of Actual Control (LAC)- the effective Sino-India border in Eastern Ladakh. 

The country has lost three precious lives – an army officer and two soldiers. The last time blood was spilled on the LAC, before the latest episode, was 45 years ago when the Chinese ambushed an Assam Rifles patrol in Tulung La.

India had lost four soldiers on October 20, 1975 in Tulung La, the last time bullets were fired on the India-China border though both the countries witnessed bitter stand-offs later at Sumdorong Chu valley in 1987, Depsang in 2013, Chumar in 2014 and Doklam in 2017.

Between 1962 and 1975, the biggest clash between India and China took place in Nathu La pass in 1967 when reports suggest that around 80 Indian soldiers were killed and many more Chinese personnel.

While three soldiers, including a Commanding Officer, were killed in the latest episode in Galwan Valley, the government describes it as a "violent clash" and does not mention opening fire.

New Delhi described the locality where the 1975 incident took place as "well within" its territory only to be rebuffed by Beijing as "sheer reversal of black and white and confusion of right and wrong".

The Ministry of External Affairs had then said that the Chinese had crossed the LAC and ambushed the soldiers while Beijing claimed the Indians entered their territory and did not return despite warnings.

The Indian government maintained that the ambush on the Assam Rifles' patrol in 1975 took place "500 metres south of Tulung" on the border between India and Tibet and "therefore in Indian territory". It said Chinese soldiers "penetrating" Indian territory implied a "change in China's position" on the border question but the Chinese denied this and blamed India for the incident.

The US diplomatic cables quoted an Indian military intelligence officer saying that the Chinese had erected stone walls on the Indian side of Tulung La and from these positions fired several hundred rounds at the Indian patrol.

"Four of the Indians had gone into a leading position while two (the ones who escaped) remained behind. The senior military intelligence officer emphasised that the soldiers on the Indian patrol were from the area and had patrolled that same region many times before," the cable said.

One of the US cables showed that former US Secretary of State and National Security Adviser Henry Kissinger sought details of the October 1975 clash "without approaching the host governments on actual location of October 20 incident". He also wanted to know what ground rules were followed regarding the proximity of LAC by border patrols.

A cable sent from the US mission in India on November 4, 1975 appeared to have doubts about the Chinese account saying it was "highly defensive".

"Given the unsettled situation on the sub-continent, particularly in Bangladesh, both Chinese and Indian authorities have authorised stepped up patrols along the disputed border. The clash may well have ensued when two such patrols unexpectedly encountered each other," it said.

Another cable from China on the same day quoted another October 1974 cable, which spoke about Chinese officials being concerned for long that "some hotheaded person on the PRC (People's Republic of China) might provoke an incident that could lead to renewed Sino-Indian hostilities. It went on to say that this clash suggested that "such concerns and apprehensions are not unwarranted".

According to the United States diplomatic cables, Chinese Foreign Ministry on November 3, 1975 disputed the statement of the MEA spokesperson, who said the incident took place inside Indian territory.

The Chinese had said "sheer reversal of black and white and confusion of right and wrong". In its version of the 1975 incident, they said Indian troops crossed the LAC at 1:30 PM at Tulung Pass on the Eastern Sector and "intruded" into their territory when personnel at the Civilian Checkpost at Chuna in Tibet warned them to withdraw.

Ignoring this, they claimed, Indian soldiers made "continual provocation and even opened fire at the Chinese civilian checkpost personnel, posing a grave threat to the life of the latter. The Chinese civilian checkpost personnel were obliged to fire back in self defence."

The Chinese Foreign Ministry spokesperson had also said they told the Indian side that they could collect the bodies "anytime" and on October 28, collected the bodies, weapons and ammunition and "signed a receipt".

The US cables from the then USSR suggested that the official media carried reports from Delhi on the October 1975 incident and they cited only Indian accounts of the incident "ridiculing alleged Chinese claims that the Indians crossed the line and opened fire first".

New Delhi, Jun 4: CSIR Director-General Shekhar Mande said on Thursday that the World Health Organisation's (WHO) decision to halt hydroxychloroquine (HCQ) drug trial was taken in haste and the global body should have actually analysed the data before making the decision.

"I firmly believe that WHO decision was taken in haste it was a kind of knee jerk reaction they should have actually analyse the data on their own before temporarily suspend the trials that is my personal opinion," Mande said.

India's nodal government agency ICMR (Indian Council of Medical Research) overseeing the country's response to the coronavirus pandemic last month wrote to the WHO citing differences in dosage standards between Indian and international trials that could explain the efficacy issues of HCQ in treating COVID-19 patients.

In addition, Dr Sheela Godbole, National Coordinator of the WHO-India Solidarity Trial and Head of the Division of Epidemiology, ICMR-National AIDS Research Institute also wrote a letter via an email to Dr Soumya Swaminathan, Chief Scientist at World Health Organisation.

In a letter, Dr Godbole stated: "There was no reason to suspend the trial for safety concern," attributing it to the current RECOVERY data which differs significantly from the non-randomised assessment by Mehra et al, a scientific paper.

Referring to the letter, the CSIR head said, "We don't know what actually happened behind the scenes but the hypothesis is that because of the paper published in Lancet. It is a very well known journal and if Lancet has done due vigilance in publishing the paper. 

Therefore, the WHO thought the paper's findings are right that's why WHO hold based on what is published on Lancet. The WHO shouldn't have accepted it immediately this should have taken their own due vigilance to find out that study is right or not."

DG CSIR said because there is a global outcry it must have put pressure on both Lancet as well as WHO and both of them now retracted from their original position. "WHO has started a trial again and Lancet has put an expression of concern on their website both of these are very welcome development for science," he said.

"So I am pretty sure that Lancet would have published the reports only after seeing somewhere the drug failed to work," Mande said.
