Orbit of Chandrayaan-2’s lander lowered, one step closer to Moon landing

September 3, 2019

New Delhi, Sept 3: The orbit of Chandrayaan-2's landing module 'Vikram' was successfully lowered for the first time on Tuesday and one final manoeuvre remained for India to pull off a historic soft-landing on the moon in the early hours of Saturday.

The 4-second de-orbiting operation was undertaken a day after the indigenously developed lander was separated from Chandrayaan-2's orbiter in a major milestone pushing India's second lunar mission into its last and most crucial leg--a controlled, soft-landing on the Moon.

The propulsion system on-board the lander was fired for the first time to lower its orbit after it started orbiting the moon independently, said the Indian Space Research Organisation(ISRO).

So far, all operations in the journey to the moon were carried out by the main orbiter of the 3,840-kg Chandrayaan-2 spacecraft that was launched into the earth's orbit on July 22 by the country's Geosynchronous Satellite Launch Vehicle, GSLV MkIII-M1.

The ISRO will perform one more de-orbiting manoeuvre on Wednesday, before the powered descent of 'Vikram' on September 7 for its landing in the lunar south pole.

A successful landing will make India the fourth country after Russia, the US and China to achieve a soft landing on the moon. But it will be the first to launch a mission to the unexplored south pole of the Moon.

"The first de-orbiting manoeuvre for Chandrayaan-2 spacecraft was performed successfully today (September 03, 2019) beginning at 0850 hrs IST as planned, using the onboard propulsion system. The duration of the manoeuvre was 4 seconds," the ISRO said giving the latest update on the Rs 978 crore Chandrayaan-2 mission.

"The orbit of 'Vikram' Lander is 104 km x 128 km. Chandrayaan-2 Orbiter continues to orbit the Moon in the existing orbit and both the Orbiter and Lander are healthy," it said, adding that the second and final manoeuvre to further lower the orbit is scheduled on September 4 between 3.30 and 4.30 am IST.

'Vikram' (with rover 'Pragyan' housed inside) is expected to touch down on the surface of the moon on September 7, between 1.30 and 2.30 am.

ISRO Chairman K Sivan has said the proposed soft-landing on the Moon is going to be a "terrifying" moment as it is something the space agency has not done before while the Lunar Orbit Insertion(LOI)manoeuvre was successfully carried out during the previous Chandrayaan-1 mission.

Following the landing, the rover 'Pragyan' will roll out from the lander between 5.30 and 6.30 am on September 7, and carry out experiments on the lunar surface for a period of one lunar day, which is equal to 14 earth days.

The mission life of the lander is also one lunar day, while the orbiter will continue its mission for a year.

Chandrayaan-2 satellite had began its journey towards the moon leaving the earth's orbit in the dark hours on August 14, after a crucial manoeuvre called Trans Lunar Insertion (TLI) that was carried out by ISRO to place the spacecraft on "Lunar Transfer Trajectory." In a major milestone, the spacecraft had successfully entered the lunar orbit on August 20 by performing the LOI operation.

The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru, the space agency has said.

The orbiter carries eight scientific payloads for mapping the lunar surface and studying the exosphere (outer atmosphere) of the Moon while the lander carries three scientific payloads to conduct surface and subsurface science experiments.

The rover carries two payloads to enhance the understanding of the lunar surface.

According to the ISRO, the objective of the mission is to develop and demonstrate the key technologies for end-to-end lunar mission capability, including soft-landing and roving on the lunar surface.

On the science front, this mission aims to further expand knowledge about the moon through a detailed study of its topography, mineralogy, surface chemical composition, thermo-physical characteristics and atmosphere, leading to a better understanding of the origin and evolution of the moon, the space agency had said.

Mumbai, Mar 9: India's Yes Bank will not be merged with State Bank of India, which is set to infuse funds in the beleaguered lender, the newly appointed administrator leading the rescue plan said in a television interview on Monday.

"There is absolutely no question of a merger," Prashant Kumar, the administrator, told the CNBC TV18 channel.

The Reserve Bank of India (RBI) on Thursday took control of Yes Bank, after the lender - which is laden with bad debts - failed to raise the capital it needs to stay above mandated regulatory requirements.

Placing Yes Bank under a 30-day moratorium, the central bank imposed limits on withdrawals to protect depositors and said it would work on a revival plan. The move spooked depositors, who rushed to withdraw funds from the bank.

Kumar, a former finance chief at SBI, assured depositors their money was safe and that the moratorium on Yes Bank might be lifted much before the deadline on April 3 and normal banking operations might resume as early as Friday.

He also mentioned that the withdrawal limit of Yes Bank may be removed by March 15, 2020.

SBI Chairman Rajnish Kumar said on Saturday the state-run bank would need to invest up to 24.5 billion rupees ($331 million) to buy a 49% stake in Yes Bank as part of the initial phase of the rescue deal, adding that the survival of troubled lender was a "must".

Jun 27: Alittle-known Indian IT firm offered its hacking services to help clients spy on more than 10,000 email accounts over a period of seven years.

New Delhi-based BellTroX InfoTech Services targeted government officials in Europe, gambling tycoons in the Bahamas, and well-known investors in the United States including private equity giant KKR and short seller Muddy Waters, according to three former employees, outside researchers, and a trail of online evidence.

Aspects of BellTroX's hacking spree aimed at American targets are currently under investigation by U.S. law enforcement, five people familiar with the matter told Reuters. The U.S. Department of Justice declined to comment.

Reuters does not know the identity of BellTroX's clients. In a telephone interview, the company's owner, Sumit Gupta, declined to disclose who had hired him and denied any wrongdoing.

Muddy Waters founder Carson Block said he was "disappointed, but not surprised, to learn that we were likely targeted for hacking by a client of BellTroX." KKR declined to comment.

Researchers at internet watchdog group Citizen Lab, who spent more than two years mapping out the infrastructure used by the hackers, released a report that BellTroX employees were behind the espionage campaign.

"This is one of the largest spy-for-hire operations ever exposed," said Citizen Lab researcher John Scott-Railton.

Although they receive a fraction of the attention devoted to state-sponsored espionage groups or headline-grabbing heists, "cyber mercenary" services are widely used, he said. "Our investigation found that no sector is immune."

A cache of data reviewed by Reuters provides insight into the operation, detailing tens of thousands of malicious messages designed to trick victims into giving up their passwords that were sent by BellTroX between 2013 and 2020. The data was supplied on condition of anonymity by online service providers used by the hackers after Reuters alerted the firms to unusual patterns of activity on their platforms.

The data is effectively a digital hit list showing who was targeted and when. Reuters validated the data by checking it against emails received by the targets.

On the list: judges in South Africa, politicians in Mexico, lawyers in France and environmental groups in the United States. These dozens of people, among the thousands targeted by BellTroX, did not respond to messages or declined comment.

Reuters was not able to establish how many of the hacking attempts were successful.

BellTroX's Gupta was charged in a 2015 hacking case in which two U.S. private investigators admitted to paying him to hack the accounts of marketing executives. Gupta was declared a fugitive in 2017, although the U.S. Justice Department declined to comment on the current status of the case or whether an extradition request had been issued.

Speaking by phone from his home in New Delhi, Gupta denied hacking and said he had never been contacted by law enforcement. He said he had only ever helped private investigators download messages from email inboxes after they provided him with login details.

"I didn't help them access anything, I just helped them with downloading the mails and they provided me all the details," he told Reuters. "I am not aware how they got these details but I was just helping them with the technical support."

Reuters could not determine why the private investigators might need Gupta to download emails. Gupta did not return follow-up messages. Spokesmen for Delhi police and India's foreign ministry did not respond to requests for comment.

HOROSCOPES AND PORNOGRAPHY

Operating from a small room above a shuttered tea stall in a west-Delhi retail complex, BellTroX bombarded its targets with tens of thousands of malicious emails, according to the data reviewed by Reuters. Some messages would imitate colleagues or relatives; others posed as Facebook login requests or graphic notifications to unsubscribe from pornography websites.

Fahmi Quadir's New York-based short selling firm Safkhet Capital was among 17 investment companies targeted by BellTroX between 2017 and 2019. She said she noticed a surge in suspicious emails in early 2018, shortly after she launched her fund.

Initially "it didn't seem necessarily malicious," Quadir said. "It was just horoscopes; then it escalated to pornography."

Eventually the hackers upped their game, sending her credible-sounding messages that looked like they came from her coworkers, other short sellers or members of her family. "They were even trying to emulate my sister," Quadir said, adding that she believes the attacks were unsuccessful.

U.S. advocacy groups were also repeatedly targeted. Among them were digital rights organizations Free Press and Fight for the Future, both of whom have lobbied for net neutrality. The groups said a small number of employee accounts were compromised, but the wider organizations' networks were untouched. The spying on those groups was detailed in a report by the Electronic Frontier Foundation in 2017, but has not been publicly tied to BellTroX until now.

Timothy Karr, a director at Free Press, said his organization "sees an uptick in breach attempts whenever we're engaged in heated and high-profile public policy debates." Evan Greer, deputy director of Fight for the Future, said: "When corporations and politicians can hire digital mercenaries to target civil society advocates, it undermines our democratic process."

While Reuters was not able to establish who hired BellTroX to carry out the hacking, two former employees said the company and others like it were usually contracted by private investigators on behalf of business rivals or political opponents.

Bart Santos of San Diego-based Bulldog Investigations was one of a dozen private detectives in the United States and Europe who told Reuters they had received unsolicited advertisements for hacking services out of India - including one from a person who described himself as a former BellTroX employee. The pitch offered to carry out "data penetration" and "email penetration."

Santos said he ignored those overtures, but could understand why some people didn't. "The Indian guys have a reputation for customer service," he said.
