Chandrayaan 2: After final lunar orbit manoeuvre, lander-orbiter separation today
In a big day for India’s second mission to the moon, the Chandrayaan 2 lander-rover will separate from the orbiter on Monday. The final orbit lowering manoeuvre of Chandrayaan 2 was conducted by scientists at Indian Space Research Organisation on Sunday evening.
Seen as one of the most challenging moves of the mission, the Vikram lander and Pragyan rover will separate out of the orbiter between 12:45 and 1:45 pm on September 2. The propulsion system on-board the indigenously developed lander will be operated for the first time after the separation move.
The next big day is on September 7 when the descent to the lunar surface will begin. The indigenously designed spacecraft — comprising an orbiter, a lander and a rover — is expected to touch down on the moon’s surface in the early hours of the morning of September 7. The rover, calledPragyan, will examine the lunar surface, search for water, and probe craters and traps that could untangle key questions about the history of the solar system.
The major concerns for the lunar landing will be the backflow of the lunar dust. A fifth central engine was added to prevent the lunar dust from covering the lander. the fifth engine would be switched on reaching the altitude of 13 m.
ISRO chairman K Sivan had said that soft-landing on the moon would be a “terrifying moment” as it is something the space agency would do for the first time.
A successful landing on the lunar surface will make India the fourth country in the world after the US, USSR, and China to soft-land on the moon. Chandrayaan 2 will also be the first mission to land on the south Pole of the moon.
Chandrayaan will continue circling the moon in a tighter orbit until reaching a distance of about 100 kilometers from its surface. Once, it lands on the surface a rover will search for water deposits that were confirmed by India’s first mission to the moon Chandrayaan.
First integrated battle group to be deployed along India-Pakistan border
As tensions simmer on the 3,323-km-long India- Pakistan border, the Indian army is set to deploy its first Integrated Battle Group (IBG) along the frontier by the end of this year, Chief of Army Staff General BipinRawat said. In all, the Indian Army plans to form and deploy 11 -13 IBGs to protect its western and eastern borders.
The ministry of defence (MoD) has cleared the reorganisation of IX Corps, based in Yol in Himachal Pradesh, to form the IBGs to be deployed along the western border. Raised in 2009, IX Corps is one of the army’s youngest corps and is part of the Chandimandir, Haryana-based Western Army Command.
This is one of the biggest reorganisations of the Army and General Rawat is its prime mover.
Restructuring of the combat potential of the Indian army will happen “selectively from sector to sector,” Rawat said. “The international border portion of J&K Kashmir will see reorganisation first followed by others, making the Indian army a leaner and meaner fighting unit,” general Rawat said, explaining the rationale behind the exercise.
In contrast with the traditional and somewhat antiquated fighting units of the army Corps, each of which comprises at least three brigades, the IBGs are smaller, meaner, self-contained fighting units, including elements of air power, artillery, amour. The IBG will encompass 6-8 battalions depending on the terrain where it is deployed and the purpose it is meant for…The composition of the IBGs will vary depending on the “task” and the “order of battle,” said a senior Army officer who did not want to be named.
“The IBGs, on an average, would comprise 20,000- 25,000 men,”said the officer. While each IBG will be a self-contained fighting unit, it can draw logistical support from other formations. The IBGs will be smaller and more flexible, allowing faster mobilisation. The formation of the IBGs, among other things, will drastically cut the time required to mobilise the strike arms of the Army. Each IBG will be commanded by an officer of the rank of major general.
The Siliguri-based XXXIII Corps, tasked with protecting the Indo-Tibetan border including Sikkim, is next in line for being transformed into an IBS. The XXXIII Corps, which moved to its present location in 1962, comprises the Black Cat, Kirpan and Striking Lion divisions and an artillery division – an estimated 30,000 thousand soldiers.
The XXXIII Corps is likely to be reorganised into five IBGs, each tasked differently, a second senior officer requesting anonymity said. The recently raised, Panagarh, West Bengal-based Mountain Strike Corps, or Brahmastra Corps, the only strike corps designated to fight along the India-China border, will also be restructured to form three IBGs.
