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.

Feb 6: India has been ranked 40th out of 53 countries on a global intellectual property index, even as the country has shown improvement in terms of scores when it comes to the protection of IP and copyright issues, a top American industry body said on Wednesday.

India was placed at 36th position among 50 countries in 2019.

India's score, however, increased from 36.04 per cent (16.22 out of 45) in 2019 to 38.46 per cent (19.23 out of 50) in 2020, a 2.42 per cent jump in an absolute score.

However, India's relative score increased by 6.71 per cent, according to the International IP Index released by Global Innovation Policy Center or GIPC of the US Chambers of Commerce.

This year, it finds itself on the 40th place among 53 countries. Two new Index economies (Greece and the Dominican Republic) scored ahead of India. The Philippines, and Ukraine leapfrogged India.

"Since the release of the 2016 National IPR Policy, the government of India has made a focused effort to support investments in innovation and creativity through increasingly robust IP protection and enforcement," the GIPC said.

Since 2016, India has improved the speed of processing for patent and trademark applications, increased awareness of IP rights among Indian innovators and creators, and facilitated the registration and enforcement of those rights, it added.

According to the eighth edition of the annual report, India's score on the Chamber's International IP Index demonstrates the country's growing investment in IP-driven innovation and creativity. The Index specifically highlights a number of reforms over the last year that strengthen India's overall IP ecosystem, it said.

"In 2019, the Delhi High Court used dynamic injunctions to disable access to copyright-infringing content online, resulting in an increase in India's score on two of the copyright-related indicators," it said.

"The use of these injunctions places India alongside global leaders in copyright enforcement, including Singapore and the UK. As a result, India scores ahead of 24 other economies in the copyright indicators," the report said.

The Delhi High Court also issued a series of judgements that provide clarity on existing statutes related to trademark protection online, resulting in a score increase on one of the trademark-related indicators, it added.

The courts issued two precedential rulings that raised the bar for the damages awarded in IP-infringement cases and may provide a deterrent for future infringement. This resulted in an increase in score on one of the trademark-related indicators, it said.

Global Innovation Policy Center or GIPC said India also continues to score well in the Systemic Efficiency indicator, scoring ahead of 28 other economies in these indicators.

"This is a result of a concerted effort by the Indian government to consult with stakeholders during IP policy formation and create greater awareness about the importance of IP protection,” it said adding that India also remains a leader in the use of targeted incentives and IP assets for small and medium-sized enterprises (SMEs).

“To continue this upward trajectory, much work remains to be done to introduce transformative changes to India’s overall IP framework and take serious steps to consistently implement strong IP standards," the report said.

GIPC has identified several challenges for India. Prominent among them being patentability requirements, patent enforcement, compulsory licensing, patent opposition, regulatory data protection, transparency in reporting seizures by customs, and Singapore Treaty of Law of TMs and Patent Law Treaty.

"We are encouraged that Indian policymakers seem to recognize this Index as a valuable resource in their efforts to strengthen the country’s promising innovation ecosystem and enhance its competitiveness in an increasingly knowledge-based global economy,” the report said.

Observing that no other economy stands to gain more from strong Indian IP than India itself, the report said for example, no industry has been hurt more by copyright violations in India than the country’s own Bollywood industry, which loses almost USD3 billion to piracy each year.

"The number one way the Modi administration can demonstrate its commitment to the success of the Atal Innovation Mission, Accelerating Growth for New India’s Innovations, Make in India, Digital India, and Startup India is to strengthen its IP framework in ways that promote the legal and regulatory certainty necessary for greater R&D investment, high-value jobs, and greater innovative and creative outputs,” it said.

"Strong IP standards can further solidify India's position as the world’s fastest-growing economy, bolstering its reputation as a destination for doing business, foreign businesses’ ability to invest and make in India, thereby supporting the growth of India’s own innovative and creative industries," the report said.

Toronto, May 7: Scientists have uncovered how bats can carry the MERS coronavirus without getting sick, shedding light on what triggers coronaviruses, including the one behind the COVID-19 pandemic, to jump to humans.

According to the study, published in the journal Scientific Reports, coronaviruses like the Middle East respiratory syndrome (MERS) virus, and the COVID19-causing SARS-CoV-2 virus, are thought to have originated in bats.

While these viruses can cause serious, and often fatal disease in people, bats seem unharmed, the researchers, including those from the University of Saskatchewan (USask) in Canada, said.

"The bats don't get rid of the virus and yet don't get sick. We wanted to understand why the MERS virus doesn't shut down the bat immune responses as it does in humans," said USask microbiologist Vikram Misra.

In the study, the scientists demonstrated that cells from an insect-eating brown bat can be persistently infected with MERS coronavirus for months, due to important adaptations from both the bat and the virus working together.

"Instead of killing bat cells as the virus does with human cells, the MERS coronavirus enters a long-term relationship with the host, maintained by the bat's unique 'super' immune system," said Misra, one of the study's co-authors.

"SARS-CoV-2 is thought to operate in the same way," he added.

Stresses on bats, such as wet markets, other diseases, and habitat loss, may have a role in coronavirus spilling over to other species, the study noted.

"When a bat experiences stress to their immune system, it disrupts this immune system-virus balance and allows the virus to multiply," Misra said.

The scientists, involved in the study, had earlier developed a potential treatment for MERS-CoV, and are currently working towards a vaccine against COVID-19.

While camels are the known intermediate hosts of MERS-CoV, they said bats are suspected to be the ancestral host.

There is no vaccine for either SARS-CoV-2 or MERS, the researchers noted.

"We see that the MERS coronavirus can very quickly adapt itself to a particular niche, and although we do not completely understand what is going on, this demonstrates how coronaviruses are able to jump from species to species so effortlessly," said USask scientist Darryl Falzarano, who co-led the study.

According to Misra, coronaviruses rapidly adapt to the species they infect, but little is known on the molecular interactions of these viruses with their natural bat hosts.

An earlier study had shown that bat coronaviruses can persist in their natural bat host for at least four months of hibernation.

When exposed to the MERS virus, the researchers said, bat cells adapt, not by producing inflammation-causing proteins that are hallmarks of getting sick, but instead by maintaining a natural antiviral response.

On the contrary, they said this function shuts down in other species, including humans.

The MERS virus, the researchers said, also adapts to the bat host cells by very rapidly mutating one specific gene.

These adaptations, according to the study, result in the virus remaining long-term in the bat, but being rendered harmless until something like a disease, or other stressors, upsets this balance.

In future experiments, the scientists hope to understand how the bat-borne MERS virus adapts to infection and replication in human cells.

"This information may be critical for predicting the next bat virus that will cause a pandemic," Misra said.
