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.

New Delhi, Jan 20: The BJP has got a brand new President in the form of JP Nadda. At around 2.30 pm, the announcement was made, bringing an end to the Amit Shah era in BJP. The party's Working President Jagat Prakash Nadda won unopposed, sparking celebrations outside the BJP headquarters here on Monday. 

Amit Shah himself was among the people who proposed Nadda's name along with Nitin Gadkari and Rajnath Singh. Soon after his annointment, BJP election returning officer Radha Mohan Singh told the media, "I announce JP Nadda as the new BJP President." Shah was also seen hugging Nadda.

The nomination process for the post of the BJP President began at 10 am and went on till 12.30 pm. For the next hour, the filed nomination paper, which was just one, was examined. Party members waitied till 2.30 pm for the candidate to withdraw if he wished to. It was after this that Nadda was declared as the man who would step into the shoes of Amit Shah.

Many in the BJP believe that although Nadda is the BJP chief now, Shah would still make all macro-level decisions like pre poll alliances or top organisational appointments. Nadda would be in charge of monitoring the day-to-day needs of the organisation. BJP sources say that Amit Shah himself wanted an arrangement like this one and personally wanted Nadda to take over. as he helped Shah formulate legislations like Triple Talaq and Citizenship Amendment Act.

The party constitution mandates completion of election of at least 50 per cent of state Presidents for the election of national President to happen. In the last few days, the BJP has completed the election of a slew of state Presidents like in West Bengal, Nagaland among others.

The process of election of the national BJP President is quite elaborate and has been described in detail in the party constitution, which says that the national president shall be elected by an electoral college, comprising members of the national council and the state councils.

"Any 20 members of the electoral college of a state can jointly propose the name of a person, who has been an active member for four terms and has 15 years of membership, for the post of national president. Such joint proposal should come from not less than five states where elections have been completed for the national council. The consent of the candidate is necessary," it says.

Who is JP Nadda?

Jagat Prakash Nadda, 59, who has his roots in the Rashtriya Swayamsevak Sangh (RSS) and its affiliates, was appointed the Bharatiya Janata Party (BJP) national President on Monday, replacing his 'mentor' and Union Home Minister Amit Shah.

Former environment, health and law minister from Himachal Pradesh, which has just four of the Lok Sabha's 543 seats, Nadda has tried to carve out his own space in national politics with his low profile and astute organisational skills, believe his party leaders.

He rose through the ranks from the Akhil Bharatiya Vidyarthi Parishad (ABVP), the student wing of the RSS, from where he has managed to build inroads from university to the state politics.

Nadda has been active on the national political scene since 2010 when he was picked by then BJP chief Nitin Gadkari to join his new team. He was made the party's national general secretary.

Born on December 2, 1960, Nadda did his graduation from Patna and holds a post-graduate degree in political science and Bachelor of Legislative Law (LL.B) from Himachal Pradesh University in Shimla.

Starting his political career as a student leader of the ABVP in 1978, Nadda had also worked both with Gadkari and Shah even in the party's youth wing -- the Bharatiya Yuva Morcha -- from 1991 to 1994.

His wife Mallika Nadda, who teaches history at the Himachal Pradesh University and is currently posted in university's campus in Delhi, was an ABVP activist too, and its national general secretary from 1988 to 1999.

In the previous BJP government (2007-12) in the state, Nadda was forced to resign as Forest Minister in 2010 owing to differences between him and then chief minister Prem Kumar Dhumal.

He was elected to the Rajya Sabha in 2012.

Nadda won his first Assembly election from Bilaspur (Sadar) in Himachal in 1993. In 1998, he again won from that seat and became the state Health Minister.

He lost the Assembly elections in 2003, but again won in 2007 and was appointed the Forest Minister in the Himachal Pradesh.

Nadda, as a forest minister, was the brain behind opening forest police stations to check forest crimes, launching community-driven plantation, setting up forest ponds and the massive plantation of deodars to boost the depleting green cover of the 'Queen of Hills', as Shimla was fondly called by the British.

A close confidant of Prime Minister Narendra Modi, Nadda was among those who were mentioned as likely aspirants to the BJP top post after Rajnath Singh was inducted into the Central government as the Home Minister in 2014.

Later, Nadda was inducted into the union cabinet in its first expansion in 2014 as the Health Minister.

Hailing Nadda's appointment, Chief Minister Jai Ram Thakur told IANS it is a proud moment that a leader belonging to a small state in the national politics is today the leader of the country's biggest national party.

His father N.L. Nadda, who was a Vice-Chancellor of the Ranchi University, resides in Bilaspur town.
