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

Agencies
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.

Bengaluru, Nov 22: For the second day running, the Karnataka BJP on Friday staged a statewide protest condemning the government’s alleged move to notify land of farmers as Waqf property.

The BJP staged a protest before the offices of Deputy Commissioners at district headquarters.

The BJP leaders are vehemently demanding that the state government cancel a 1974 Gazette notification in this regard.

The agitators are also demanding scrapping of the Waqf Board and the resignation of Chief Minister Siddaramaiah and Minister for Waqf and Housing Zameer Ahmad Khan.

The BJP MLAs, MLCs, MPs gathered in the premises of Freedom Park and staged a protest under the leadership of Leader of Opposition R. Ashoka and slammed the state government.

MLA T.S. Srivatsa led the protest in Mysuru and hundreds of party workers and farmers staged the protest under the leadership of former MP Pratap Simha in Kodagu.

Former MP Sumalatha Ambareesh led the agitation in Mandya.

This was the first time that Sumalatha took part in the party’s programme after the Lok Sabha elections.

State President B.Y. Vijayendra claimed, “The Congress government in Karnataka is issuing notices to farmers claiming the ownership of their lands to the Waqf Board and pushing them on the streets overnight.”

In the first week of December, three teams formed by the BJP will travel across the state and record the grievances of farmers.

“The state government is attempting to snatch away the lands belonging to temples as well,” Vijayendra alleged and added that the teams would comprise all senior leaders of the BJP.

Meanwhile, the police have taken Sri Ram Sena chief Pramod Muthalik into custody while staging a protest march to the office of Zameer Ahmad Khan in Bengaluru.

Muthalik along with Hindutva activists was planning to lay siege to Zameer’s office over the Waqf row.

The police stopped Muthalik and requested him to submit the memorandum by reaching the minister’s office in a vehicle. However, Muthalik refused to go with the police and continued his footmarch. The police took him into custody following arguments.

Mangaluru: A tragic accident took place on Saturday at Chembugudde near Thokkottu, claiming the life of a 47-year-old woman after a tanker lorry ran over her. The victim, identified as Rahmat H Rashid, was riding pillion with her husband, Abdul Rashid G, on their scooter. 

The couple was traveling from Yenepoya Hospital to Bajpe when the scooter skidded on the poorly maintained road. Rahmat fell onto the road and was fatally struck by a tanker lorry that was coming from behind. Despite being rushed to the hospital, doctors declared her dead upon arrival.

The incident prompted a swift response from the DYFI Ullal Taluk Committee, which staged a protest on Saturday night, condemning the unsafe condition of the road. Nithin Kuthar, president of the committee, criticized MLA and Legislative Assembly Speaker UT Khader for failing to ensure safe infrastructure, despite touting the road as toll-free. 

Kuthar demanded immediate repairs, warning that the committee would march to the MLA’s office with black flags if the road is not fixed within a week.

Former DYFI State President Sunil Kumar Bajal also voiced frustration over the deteriorating condition of Thokkottu market, highlighting the struggles people face while crossing roads riddled with dangerous potholes. In response to public outcry, temporary repairs were made to the road at Chembugudde on Sunday, though locals remain wary and demand a more permanent solution.
