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.

Microsoft's Indian-origin CEO Satya Nadella on Monday voiced concern over the contentious Citizenship Amendment Act (CAA), saying what is happening is "sad" and he would love to see a Bangladeshi immigrant create the next unicorn in India.

His comments came while speaking to editors at a Microsoft event in Manhattan where he was asked about the contentious issue of CAA which grants citizenship to persecuted non-Muslim minorities from Pakistan, Bangladesh and Afghanistan.

"I think what is happening is sad... It's just bad.... I would love to see a Bangladeshi immigrant who comes to India and creates the next unicorn in India or becomes the next CEO of Infosys," Nadella was quoted as saying by Ben Smith, the Editor-in-Chief of New York-based BuzzFeed News.

In a statement issued by Microsoft India, Nadella said: "Every country will and should define its borders, protect national security and set immigration policy accordingly. And in democracies, that is something that the people and their governments will debate and define within those bounds.

"I’m shaped by my Indian heritage, growing up in a multicultural India and my immigrant experience in the United States. My hope is for an India where an immigrant can aspire to found a prosperous start-up or lead a multinational corporation benefitting Indian society and the economy at large".

The Centre last week issued a gazette notification announcing that the CAA has come into effect from January 10, 2020.

The CAA was passed by Parliament on December 11.

According to the legislation, members of Hindu, Sikh, Buddhist, Jain, Parsi and Christian communities who have come from Pakistan, Bangladesh and Afghanistan till December 31, 2014, due to religious persecution will not be treated as illegal immigrants but given Indian citizenship.

There have been widespread protests against the Act in different parts of the country.

In Uttar Pradesh, at least 19 persons were killed in anti-CAA protests.

New Delhi, Jan 11: Islamic preacher Zakir Naik has revealed that the Bharatiya Janata Party-led government offered to drop false money-laundering charges against him and provide with a "safe passage to India" in return for his support to the government's move to revoke Article 370 of the Constitution.

In a statement issued by Naik's PR team on Saturday, the Islamic preacher said that he was approached by a representative of the Indian government in September, who offered him the said deal on Kashmir, which he refused.

"Three and a half months before, the Indian officials approached me for a private meeting with a representative of the Indian government. When he came to Putrajaya (a Malaysian city), in the fourth week of September 2019, to meet me, he said that he is coming after personally meeting and under the direct instructions of the Prime Minister of India Narendra Modi and the Home Minister of India Amit Shah," Naik said in a video statement released by his Mumbai-based PR team.

Naik, who has been living in Malaysia for the last three years, is facing charges of inciting communal disharmony and committing unlawful activities in India.

"(The representative) said that he wanted to remove the misconceptions and miscommunications between myself (Naik) and the Indian government, and wants to provide me a safe passage to India," he added. "He (the representative) said that he would like to use my connections to better the relationship between India and the other Muslim countries."

"The meeting lasted for several hours. He told me that he wanted me to support the BJP government when they revoked Article 370 in Kashmir. And I flatly refused," he added.

Naik said that after he refused the offer, he was further asked to not make public statements against the BJP or Prime Minister Narendra Modi.

May 7: India is projected to record the highest number of births in the 9 months since COVID-19 was declared a pandemic in March, with more than 20 million babies expected to be born in the country between March and December, according to top UN body.

The United Nations Children's Fund (UNICEF) warned that pregnant mothers and babies born during the pandemic across the world were threatened by strained health systems and disruptions in services.

An estimated 116 million babies will be born under the shadow of COVID-19 pandemic, UNICEF said on Wednesday, ahead of Mother's Day, observed on May 10.

These babies are projected to be born up to 40 weeks after COVID-19 was recognised as a pandemic on March 11.

The highest numbers of births in the 9 months since the pandemic was declared are expected to occur in India, where 20.1 million babies are projected to be born between March 11 and December 16. Other countries with the expected highest numbers of births during this period are China (13.5 million), Nigeria (6.4 million), Pakistan (5 million) and Indonesia (4 million), it said.

"Most of these countries had high neonatal mortality rates even before the pandemic and may see these levels increase with COVID-19 conditions," UNICEF said.

It is estimated that there will be 24.1 million births in India for the January-December 2020 period.

UNICEF warned that COVID-19 containment measures can disrupt life-saving health services such as childbirth care, putting millions of pregnant mothers and their babies at great risk.

Even wealthier countries are affected by this crisis. In the US, the sixth-highest country in terms of the expected number of births, over 3.3 million babies are projected to be born between March 11 and December 16.

"New mothers and newborns will be greeted by harsh realities," UNICEF said, adding they include global containment measures such as lockdowns and curfews; health centres overwhelmed with response efforts; supply and equipment shortages; and a lack of sufficient skilled birth attendants as health workers, including midwives, are redeployed to treat COVID-19 patients.

"Millions of mothers all over the world embarked on a journey of parenthood in the world as it was. They now must prepare to bring a life into the world as it has become – a world where expecting mothers are afraid to go to health centres for fear of getting infected, or missing out on emergency care due to strained health services and lockdowns," UNICEF Executive Director Henrietta Fore said.

"It is hard to imagine how much the coronavirus pandemic has recast motherhood" Fore said.

UNICEF said its analysis was based on data from World Population Prospects 2019 of the UN Population Division.

An average full-term pregnancy typically lasts a complete 9 months, or 39 to 40 weeks. For the purposes of this estimate, the number of births for a 40-week period in 2020 was calculated.

The 40-week period of March 11 to December 16 is used in this estimate based upon the WHO's March 11 assessment that COVID-19 can be characterised as a pandemic.

UNICEF warned that although evidence suggests that pregnant mothers are not more affected by COVID-19 than others, countries need to ensure they still have access to antenatal, delivery and postnatal services.

Similarly, sick newborns need emergency services as they are at high risk of death. New families require support to start breastfeeding, and to get medicines, vaccines and nutrition to keep their babies healthy, it said.

"This is a particularly poignant Mother's Day, as many families have been forced apart during the coronavirus pandemic, but it is also a time for unity, a time to bring everyone together in solidarity. We can help save lives by making sure that every pregnant mother receives the support she needs to give birth safely in the months to come," Fore said.

Issuing an urgent appeal to governments and health care providers to save lives in the coming months, UNICEF said efforts must be made to help pregnant women receive antenatal checkups, skilled delivery care, postnatal care services, and care related to COVID-19 as needed.

Ensure health workers are provided with the necessary personal protective equipment and get priority testing and vaccination once a COVID-19 vaccine becomes available so that can deliver high quality care to all pregnant women and newborn babies during the pandemic, it said.

While it is not yet known whether the virus is transmitted from a mother to her baby during pregnancy and delivery, UNICEF advised all pregnant women to follow precautions to protect themselves from exposure to the virus.

Closely monitor themselves for symptoms of COVID-19 and seek advice from the nearest designated facility if they have concerns or experience symptoms. Pregnant women should also take the same precautions to avoid COVID -19 infection as other people: practice physical distancing, avoid physical gatherings and use online health services, it said.

UNICEF said even before COVID-19 pandemic, an estimated 2.8 million pregnant women and newborns died every year, or 1 every 11 seconds, mostly of preventable causes.

The agency called for immediate investment in health workers with the right training, who are equipped with the right medicines to ensure every mother and newborn is cared for by a safe pair of hands to prevent and treat complications during pregnancy, delivery and birth.
