''Mars mission is a publicity stunt'': Madhavan Nair

Bangalore, Jul 24: India's 'Moon Man' has contested ISRO's contention that the upcoming 'desi' Mars orbiter mission would undertake meaningful research, and dubbed the Rs 450 crore venture as a "publicity stunt".

"ISRO is embarking on an extravagant mission which at best can serve as a publicity stunt", G Madhavan Nair, a former chief of the Bangalore-headquartered Indian Space Research Organisation, told PTI here.

The country was facing an acute shortage of communication transporters, noted Nair during whose tenure of six years as ISRO Chairman and Secretary in the Department of Space, 25 successful space missions were accomplished, including India's maiden moon venture Chandrayaan-I.

ISRO should have solved this issue by following the K Kasturirangan Committee recommendation, he argued.

"Even if the launch takes place, it will be yet another PSLV launch only. One has to wait nearly eight months before anything of MARS is heard. This is an issue which needs a serious review by the scientific community", Nair said.

According to him, GSLV was the vehicle identified because it could take a respectable satellite of nearly 1,800 kg. This could have provided more than a dozen instruments on board and the spacecraft would have been placed in a near circular orbit for a meaningful remote sensing mission of Mars.

"But what is the fate of the much hyped Mars Orbiter Mission (ISRO's mars mission as conceived now) - there were delays in solving the problems of GSLV so a study was undertaken see what can be done with PSLV. Nearly 1500 kg satellite can be taken to Mars, but due to fuel limitation it could at best be placed in an elliptical orbit of 380 km perigee and 80000 km apogee. No one would attempt a resource survey or mapping mission with such widely varying altitudes", Nair said.

ISRO Chairman K Radhakrishnan told PTI recently the Mars mission would undertaken meaningful research.

The primary objectives of the mission, according to ISRO, are to demonstrate India's technological capability to send a satellite to orbit around Mars and conduct meaningful experiments such as looking for signs of life, take pictures of the red planet and study Martian environment.

ISRO is going to start in August first week the assembly of PSLV-C25, the rocket on board of which the Mars orbiter would be launched any day between October 21 and November 7.

Elaborating further, Nair said though there was an initial estimate of 25 kg for the scientific instruments, on detailed analysis provision it was reduced to a meagre 14 kg.

This may further come down.

As it stands today, there could be just five instruments -- a Mars Colour camera (MCC) to take pictures of Mars; Mass Methane Sensor (MMS) to study the amount and origin of Methane on Mars; Lyman Alpha Photometer (LAP), to study the ratio of Hydrogen and Deuterium on Mars; Mars Exosphere Neutral Composition Analyser (MENCA), to study Martian atmosphere AND Thermal Infrared Imaging Spectrometer (TIS).

"Constraints on mass are likely to reduce these payloads," he said.  "With such skeletal instruments on board a spacecraft travelling at altitudes varying from 380 and 80,000 km what meaningful science can be done is a big question mark. This is exactly a case of cutting the head to suit the hat," he contended.

Nair said in Chandrayaan-I when the number of instruments had to be increased, the propulsive power of PSLV was enhanced whereas for Mars Orbiter Mission the desired rocket was not available and the spacecraft was curtailed to an insignificant size.

"Not only that, many of the sub-systems of (the proposed) Chandrayan-2 were cannibalised for the Mars Mission delaying the more meaningful Chandrayan-2.

Chandrayan-2 may take place in 2016 or beyond. China is going with similar mission to moon later this year, not to Mars," he said.

"Mission to Mars is claimed to be complex and challenging. No one familiar with orbital mechanics will appreciate this. The sequence for Mars Mission is identical from the earth's orbit. It will be catapulted on path which will reach near moon or Mars. It may take five days to Moon and eight months to Mars because of the long distance. One has to wait and watch and nothing significant needs to be done during this long wait."

New Delhi, 17: Tensions on the Indo-China border have spiked to the highest since 1962 after over 20 troops, including an Indian commanding officer, were killed in the face-off in Galwan valley that has seen a six-week long standoff underway with the Peoples Liberation Army.

The Army said that the soldiers – including the Commanding Officer of 16 Bihar regiment in charge of the area – died while a `de-escalation process’ was underway. Sources said that this death toll could rise up as some soldiers are currently not accounted for after PLA troops attacked with spiked sticks and stones in the Galwan valley.

Chinese side also has casualties but the number is still not known. The Indian death toll is perhaps the worst single day loss in decades and has come at a time when thousands of troops are forward deployed in Eastern Ladakh.

ET was the first to report on May 12 about a massive troop build up in the Galwan valley, which is an old flashpoint that had seen action in the 1962 war as well.

There have been reports of casualties on the Chinese side in the clash but numbers are currently not available. Worryingly, information from the ground suggests that several Indian soldiers, including four officers, are missing and could have been taken captive by a vastly larger Chinese force. Their status is still not known.

“During the de-escalation process underway in the Galwan Valley, a violent face-off took place yesterday night with casualties. The loss of lives on the Indian side includes an officer and two soldiers. Senior military officials of the two sides are currently meeting at the venue to defuse the situation,” an Indian Army statement reads.

The Ministry of External Affairs said that the clash occurred when the Chinese side violated the LAC. “On the late-evening and night of 15th June, 2020 a violent face-off happened as a result of an attempt by the Chinese side to unilaterally change the status quo there. Both sides suffered casualties that could have been avoided had the agreement at the higher level been scrupulously followed by the Chinese side,” a statement reads.

The loss of the Commanding Officer is especially devastating and he had been directly involved in de-escalation talks with the Chinese side, including one hours before the clash took place. Sources said that the talks on Monday morning had led to an agreement for Chinese forces to withdraw from Indian territory as part of the disengagement.

According to one version, the CO had gone to the standoff point with a party of 50 men to check if the Chinese had retreated as promised. As the Indian side proceeded to demolish and burn illegal Chinese structures on its side of the LAC, including an observation post constructed on the South bank of the river, a fresh stand off took place as a large force of Chinese troops returned back.

Sources said that a Chinese force in excess of 250 quickly assembled near Patrol Point 14 and were physically stopped by Indian soldiers from entering Indian territory. Soldiers from both sides did not use firearms but the Chinese soldiers carried spiked sticks to attack.

Given the terrain of the region, a part of the standoff and clash took place in the middle of the Galwan river that is currently flowing at full spate, leading to high casualties as injured soldiers got swept away. Indian soldiers have to cross the Galwan river at atleast five points to reach PP 14, which marks the LAC.

Chinese media reports on Tuesday quoted the spokesperson from its Western Theatre Command as laying claim over the Galwan valley region and blaming the Indian side for the clash. Reports quoted Col Zhang Shuili as saying that India has violated the consensus made during Army commander level talks.

As reported, Galwan river area has a painful history with China, with Peoples Liberation Army (PLA) soldiers surrounding a freshly set up Indian Army post in July 1962, in what would be one of the early triggers to the Sino-Indian war. At an Army post that was overrun at Galwan, 33 Indian soldiers were killed and several dozen taken captive in 1962.

In the past, the Doklam crisis in 2017 saw tensions building up along the Pangong Tso lake as well with soldiers engaging in a fight with sticks and stones. However, the Eastern Ladakh standoff is of a much more serious nature, with over 6000 Chinese troops lined up with tanks and artillery, faced off with a larger Indian forces. Troop build up has also been reported across the borders in Himachal Pradesh, Uttarakhand, Sikkim and Arunachal.

Jun 20: Congress leader Rahul Gandhi on Saturday attacked Prime Minister Narendra Modi over his remark that neither is anyone inside India's territory nor has any of its posts been captured, alleging that the PM has "surrendered" Indian territory to Chinese aggression.

In a statement on the all-party meeting called by Modi on Friday to discuss the situation at the India-China border, the government said, "At the outset, prime minister clarified that neither is anyone inside our territory nor is any of our post captured."

Tagging PM's remarks with his tweet, Gandhi said, "PM has surrendered Indian territory to Chinese aggression."

"If the land was Chinese: 1. Why were our soldiers killed? 2. Where were they killed?" Gandhi said.

The categorical statement by the prime minister came in the wake of reports that Chinese military has transgressed into the Indian side of the Line of Actual Control, the de-facto border, in several areas of eastern Ladakh including Pangong Tso and Galwan Valley.

Soon after Gandhi's tweet, Union Home Minister Amit Shah posted video of father of a soldier, who was injured in Galwan face-off, and hit out at the Congress leader, accusing him of indulging in "petty politics".

"A brave armyman’s father speaks and he has a very clear message for Mr. Rahul Gandhi. At a time when the entire nation is united, Mr. Rahul Gandhi should also rise above petty politics and stand in solidarity with national interest," Shah wrote.

The prime minister's assertion came even as Congress president Sonia Gandhi, at the all-party meet, questioned the government's handling of the situation, asking if there was any intelligence failure, and seeking assurance that China will "revert" to its original position.

Rahul Gandhi on Friday accused senior ministers in the government of "lying" to protect the prime minister and that the Centre was "fast asleep" while martyred jawans paid the price in Ladakh.

The former Congress chief also tagged a one-minute video of a jawan's father saying the Indian soldiers were unarmed when they were attacked by Chinese troops.

He has been questioning the government on the LAC standoff and asking how the Chinese occupied Indian territory and why Indian soldiers were sent "unarmed to martyrdom" in Ladakh.

Twenty Indian Army personnel, including a colonel, were killed in a clash with Chinese troops in the Galwan Valley in eastern Ladakh on Monday night, the biggest military confrontation in over five decades that has significantly escalated the already volatile border standoff in the region.

New Delhi, Jan 16: The Arvind Kejriwal-led Delhi government on Thursday rejected the mercy plea of Mukesh, one of the convicts in the 2012 Nirbhaya case.

The mercy plea was then forwarded to Lieutenant Governor, who has now sent it to Union Ministry of Home Affairs.

The convicts were sentenced to death for raping a 23-year-old woman in a moving bus in the national capital on the intervening night of December 16-17, 2012.

The victim, who was later given the name Nirbhaya, had succumbed to injuries at a hospital in Singapore where she had been airlifted for medical treatment.
