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, Jul 18: The Covid-19 lockdown-led reduction in air pollution levels across five Indian cities, including Delhi and Mumbai, may have prevented about 630 premature deaths, and saved USD 690 million in health costs in the country, according to a new study.

Scientists, including those from the University of Surrey in the UK, assessed the levels of harmful fine particulate matter (PM2.5) from vehicles and other sources in five Indian cities -- Delhi, Mumbai, Kolkata, Chennai and Hyderabad -- since the beginning of the lockdown period.

The study, published in the journal Sustainable Cities and Society, compared these lockdown PM2.5 figures from 25 March up until 11 May, with those from similar periods of the preceding five years, and found that the measure reduced pollution levels in all these places.

According to the scientists, during this period, the levels of these harmful air pollutants reduced by 10 per cent in Mumbai, and by up to 54 per cent in Delhi.

"The percentage reduction for the other cities ranged from 24 to 32 per cent, which was slightly smaller than the measured values for Delhi and Mumbai," the scientists noted in the study.

"While the reduction in PM2.5 pollution may not be surprising, the size of the reduction should make us all take notice of the impact we have been having on the planet," said Prashant Kumar, a co-author of the study from the University of Surrey.

The scientists said these reductions in PM2.5 were comparable to those reported in other cities across the world, such as in Austria's capital Vienna (60 per cent), and Shanghai (42 per cent) in China.

They also calculated the monetary value of the reduced mortality due to air pollution and found that the lowered levels of PM2.5 may have saved 630 people from premature death, and USD 690 million in health costs in India.

According to the researchers, the present lockdown situation offers observational opportunities regarding potential control systems and regulations for improved urban air quality.

They said an integrated approach might help in understanding the overall impacts of Covid-19 lockdown-style interventions and support the implementation of relevant policy frameworks.

"This is an opportunity for us all to discuss and debate what the 'new normal' should look like - particularly when it comes to the quality of the air we breathe," Kumar said.

Jan 31: Twenty-three children aged between six months and 15 years, who had been taken hostage by a murder accused after inviting them to his daughter's birthday party, were rescued late on Thursday night after police killed their captor in a village here.

The hostage drama began at Kasaria village in the afternoon and continued for about eight hours.

"The accused was killed and there were about 23 children who were rescued safely," Additional Chief Secretary (Home) Awanish Awasthi told reporters at a hurriedly called press conference at 1.20 am.

"The accused had invited the children for the birthday party of his daughter and held them hostage. It started about 5.45 pm on January 30 and continued for about eight hours," Director General of Police (DGP) O P Singh said, adding that in the entire operation they had tried to "engage" the accused and were successful.

He said the accused, identified as Subhash Batham, had initially released a six-month-old girl by handing her over to his neighbour from a balcony.

Eyewitnesses said a restive crowd gathered outside the house where the children were kept with some women wailing and praying for their safe release.

The crowd broke open the door of the house to rescue the children, they said.

As the accused opened fire, the police retaliated killing him on the spot.

In the exchange of fire, the captor's wife was injured, but none of the children suffered any injury.

A man and two policemen also suffered bullet injuries.

The motive of the accused was not known immediately.

Chief Minister Yogi Adityanath monitored the situation in Farrukhabad, which is nearly 200 km from state capital Lucknow.

"The CM as soon as he got to know about the incident called a meeting of the crisis management group and personally monitored the situation and ensured children are rescued safely," Awasthi said.

Earlier, a team of NSG (National Security Guard) commandos had taken a special aircraft to reach Farukhabad, a senior security official in Delhi said.

Police said Batham, a murder accused, seemed to be mentally unstable.

Inspector-General of Police, Kanpur Range, Mohit Agarwal, said, "The man called the children for a birthday party and held them hostage in the basement of the house. He fired six shots from inside the building."

Batham initially wanted to talk to the local MLA, but refused to speak to the leader when he arrived, Agarwal said.
