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).

Nearly 80 Air India Express flights were canceled after the cabin crew members went on a "mass sick leave", official sources said on Wednesday.

As many as 79 international and domestic flights were canceled after about 300 senior cabin crew members reported sick at the last minute and switched off their mobile phones.

The Air India Express management is currently trying to reach out to the crew, who are protesting against the new employment term at the Tata Group-owned airline, sources said.

The cabin crew has also alleged that there was a lack of equality in the treatment of the staff after the merger with Tata Group. They claim that some staff members were offered lower job position despite clearing interviews, sources said.

"A section of our cabin crew has reported sick at the last minute, starting last night, resulting in flight delays and cancellations. While we are engaging with the crew to understand the reasons behind these occurrences, our teams are actively addressing this issue to minimise any inconvenience caused to our guests as a result," an Air India Express spokesperson said.

"We sincerely apologise to our guests for this unexpected disruption and emphasise that this situation does not reflect the standard of service we strive to provide," the spokesperson added.

Guests impacted by cancellations will be offered a full refund or complimentary rescheduling to another date, the airline said.

Several passengers took to their social media accounts and complained about the sudden cancellations of their flights. They said that they had "no information" about the cancellations.

Some "very disappointed" passengers on X said that they had reached the airport when they were informed that their flights were canceled.

"We apologise for any inconvenience. Please be informed that your flight has been canceled due to operational reasons," Air India Express said in response to one of the posts on X.

The Supreme Court Friday granted interim bail to Delhi Chief Minister Arvind Kejriwal till June 1 in the excise policy case.

The top court, however, stated that it will be passing a detailed order over the matter soon.

On Thursday, the Enforcement Directorate had opposed the move to grant interim bail to Kejriwal saying that “any special concession” to him will “amount to anathema to the rule of law and equality… thereby creating two separate classes in the country viz. ordinary people, who are bound by the rule of law as well as the laws of the country, and politicians who can seek exemption from the laws”.

The ED had arrested Kejriwal on March 21 in the excise policy case.

“The right to campaign for an election is neither a fundamental right nor a constitutional right and not even a legal right,” the ED said, maintaining that to its knowledge, “no political leader has been granted interim bail for campaigning even though he is not the contesting candidate”.

After the ED filed its affidavit, the AAP, in a press release, said, “The legal team of Delhi Chief Minister and AAP National Convenor, Shri Arvind Kejriwal, has raised strong objection to the affidavit filed by the Enforcement Directorate opposing interim bail in the Supreme Court.”

Several women, believed to be victims of Prajwal Revanna, have left their homes in Karnataka's Hassan district over the last ten days, according to media reports.

These departures reportedly come amid fear and stigma after their identities became public due to the circulating video clips showing the women who were allegedly sexually assaulted by Prajwal Revanna.

"The entire district is in H D Revanna’s control. You speak ill about them and chances are high that it will reach them, because the family and the party have a large following," a shopkeeper in Hagare - 20 km from Hassan – was quoted as saying by the news paper. 

Hassan is the bastion of the JD(S) supremo Deve Gowda, and Prajwal, his grandson, is the sitting MP.

The family of the woman whose complaint was the basis of the first FIR against Prajwal has now left their home, the publication reported, citing a neighbour who said, "The woman worked at Revanna’s house as a house help. Some of her videos started to circulate and then, her house was seen locked. We don’t know when she left."

Notably, a former Zilla Panchayat member has also filed a rape case against Prajwal, and in that village many women who worked for the party formerly are now incommunicado, a JD(S) leader told the publication. "We noticed many of the party women deleting their photos with Prajwal on social media. In some instances, men are questioning their wives about their association with the MP. It is shattering the lives of many women in the district," he said.

The local leader added that the former Zilla Panchayat member was there on April 24, but no one had seen the family since the videos came out.

The case is currently being probed by an SIT team and when they reached the Revanna residence, party workers were reportedly heard talking about the women. "I know this woman, she lived close to our residence and was very active in JD(S) activities. Her house is locked… she has small children," one said, as per IE.

Another shopkeeper added, "It was really wrong to reveal the faces of the women. I know some of them, and they have gone into hiding. We don’t know whether they can return."

He noted that it is impossible to survive in Hassan while fighting a case against the Revanna family.

While Prajwal's father, H D Revanna is in SIT custody, a Blue Corner notice has been issued against the sitting MP.
