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

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.

Cybercriminals continue to exploit public fear of rising coronavirus cases through malware and phishing emails in the guise of content coming from the Centers for Disease Control and Prevention (CDC) in the US and World Health Organisation (WHO), says cybersecurity firm Kaspersky.

In the APAC region, Kaspersky has detected 93 coronavirus-related malware in Bangladesh, 53 in the Philippines, 40 in China, 23 in Vietnam, 22 in India and 20 in Malaysia. 

Single-digit detections were monitored in Singapore, Japan, Indonesia, Hong Kong, Myanmar, and Thailand. 

Along with the consistent increase of 2019 coronavirus cases comes the incessant techniques cybercriminals are using to prey on public panic amidst the global epidemic, the company said in a statement. 

Kaspersky also detected emails offering products such as masks, and then the topic became more commonly used in Nigerian spam emails. Researchers also found scam emails with phishing links and malicious attachments.

One of the latest spam campaigns mimics the World Health Organisation (WHO), showing how cybercriminals recognise and are capitalising on the important role WHO has in providing trustworthy information about the coronavirus.

"We would encourage companies to be particularly vigilant at this time, and ensure employees who are working at home exercise caution. 

"Businesses should communicate clearly with workers to ensure they are aware of the risks, and do everything they can to secure remote access for those self-isolating or working from home," commented David Emm, principal security researcher.

Some malicious files are spread via email. 

For example, an Excel file distributed via email under the guise of a list of coronavirus victims allegedly sent from the World Health Organisation (WHO) was, in fact, a Trojan-Downloader, which secretly downloads and installs another malicious file. 

This second file was a Trojan-Spy designed to gather various data, including passwords, from the infected device and send it to the attacker.

New Delhi, Feb 5: Kapil Baisala who opened fired at the Shaheen Bagh protest site last week is a member of the Aam Aadmi Party, police said on Tuesday, sparking a war of words between the BJP and the AAP.

While the BJP accused Chief Minister Arvind Kejriwal of "playing" with the security of the country, the AAP hit back, stating the saffron party was indulging "dirty politics".

Deputy Commissioner of Police (Crime Branch) Rajesh Deo said that Baisala and his father joined the AAP in early 2019.

Baisala's family, however, refuted the police's claim.

Kapil Baisala's uncle Fatesh Singh told PTI, "I have no idea where these photographs are circulating from. My nephew Kapil had no association with any political party nor does any other member from the family. My brother, Gaje Singh, (Baisala's father) fought assembly elections in 2008 on a Bahujan Samaj Party ticket and lost. After that no one from our family had any links with any political party."

Singh added that Baisala also doesn't have friends associated with the AAP or any other political party.

Gaje had also contested the 2012 civic body polls from the BSP, the police said.

The police officer said they seized Baisala's mobile phone and retrieved WhatsApp data.

On Saturday, Baisala fired two rounds in air at Shaheen Bagh. According to eyewitnesses, the man shouted "Hindu Rashtra Zindabad" and fired two rounds.

He was overpowered by the police and later arrested.

In the pictures, it was seen that he and his father joined the party in the presence of Atishi Marlena, Sanjay Singh and other leaders, sources said.

The police said on Thursday, Baisala, along with his friend Sarthak Larolla, went to Shaheen Bagh from his village on a bike.

Through CCTV footage, it was found they took the DND flyover, Maharani Bagh, Sarai Jullena and reached Holy Family hospital, a senior police officer said.

"Baisala was not comfortable on the bike as he had hidden the pistol near his waist. They entered the hospital's parking where he adjusted the pistol, used the washroom and headed towards Shaheen Bagh," the senior official added.

When they reached the protest site, Larolla left the spot with the motorcycle and Baisala's mobile phone. Later, Baisala fired two rounds in the air and was apprehended. The weapon was recovered from near the spot, the police said.

Larolla joined the investigation and the mobile phone was seized from his residence.

Baisala has been remanded to police remand for two days.

He had bought the pistol around seven years ago for his brother's marriage. The source of the weapon from where he procured it is yet to identified, police said.

The sources said Baisala was previously also involved in firing incident but was never caught nor was a case registered against him.

Hitting out at the AAP, BJP president J P Nadda accused Kejriwal of playing with the security of the country and said that the people will give the party a befitting reply.

"I want to make clear to Kejriwal that this country is bigger than any election, any government, and the country will not forgive those who play with its security. The people of Delhi will give a befitting reply," Nadda tweeted.

Senior AAP leader Sanjay Singh asked on whose directions was the Delhi Police accusing his party.

"Before the police revealed it (Baisala being an AAP member), how did BJP's Delhi president Manoj Tiwari come to know about it," Singh asked and accused the police of maligning the party.

London, May 14: Fugitive liquor baron Vijay Mallya on Thursday urged the Central government to accept his offer to repay 100 per cent of his loan dues and close the case against him.

While congratulating the Centre for introducing Rs 20 lakh crore relief package to boost the economy amid the coronavirus lockdown, Mallya, lamented that his repeated attempts to pay back his dues have been ignored by the Indian government.

"Congratulations to the Government for a Covid 19 relief package. They can print as much currency as they want BUT should a small contributor like me who offers 100% payback of State-owned Bank loans be constantly ignored? Please take my money unconditionally and close," he tweeted.

Earlier this month, Mallya had sought permission to appeal against a ruling ordering his extradition to India in Britain's highest court the UK Supreme Court.

The application comes two weeks after the High Court in London - the UK's second-highest court - dismissed Mallya's appeal against a lower court ruling that he be sent to India to face charges of defrauding a consortium of Indian banks of more than Rs 9,000 crores relating to the collapse of Kingfisher Airlines in 2012.
