Chandrayaan-2 Landing Live Updates: Hours after India’s dream of landing a spacecraft on moon remained unfulfilled, the Indian Space Research Organisation (ISRO) in its latest update said, “90-95 per cent of mission objectives have been accomplished, notwithstanding the loss of communication with the Lander.”

Support poured in for India’s space agency as the nation stood together to appreciate its accomplishments despite failing to make a smooth soft-landing. The failure happened 13 minutes after the Vikram lander of Chandrayaan-2 began its descent.

ISRO chief Sivan confirmed that communication with the lander had been lost and said that data has been analysed. Though the expected soft-landing of the Vikram lander was not accomplished, the Chandrayaan-2 mission is far from over. Prime Minister Narendra Modi, who had joined the scientists 15 minutes before the descent began, was briefed by a sombre Sivan on the development. “When ISRO has its encyclopedia of success, some hurdles cannot put its flight out of trajectory. Learnings from today will make us stronger and better; there will be a new dawn,” PM Modi had told the ISRO team.

Russia, US and China remain to be the only nations to land missions on moon

Only the United States, Russia and China have landed on the moon. Beijing's Chang'e-4 probe touched down on the far side this year, while Israel made an unsuccessful attempt to land its Beresheet spacecraft on the moon in April. The south pole is believed to contain water as craters in the region are largely unaffected by the high temperatures of the sun. ISRO had hoped to confirm the presence of water in the form of ice, first detected on its mission in 2008.

Mission operated at low cost, budget for 'Avengers: Endgame' was twice: BBC hails ISRO

The BBC wrote that the mission had made global headlines because it was "so cheap". "The budget for Avengers: Endgame, for instance, was more than double at an estimated $ 356 million. But this isn't the first time ISRO has been hailed for its thrift. Its 2014 Mars mission cost $ 74 million, a tenth of the budget for the American Maven orbiter," it said.

In the most optimistic case, it could only be a problem of communication failure. It is possible that Vikram landed on the moon as planned, but midway through its journey stopped communicating with the ground station. The chances of this having happened are extremely slim, considering that the graph on the screens of the control room depicting the expected and actual deceleration did begin to diverge after 13 minutes from the descent. So the speed was noticed to be larger than required even before communication was lost. READ MORE

Chandrayaan-2 landing attempt will help India's future missions: Former NASA astronaut

The lessons learned from India's “bold attempt” to soft land Chandrayaan-2's Vikram module on the lunar surface will help the country during its future missions, former NASA astronaut Jerry Linenger said on Saturday.

40% lunar missions in last 60 years failed: NASA fact sheet

The success ratio of lunar missions undertaken in the last six decades is 60 per cent, according to US space agency NASA's 'Moon Fact Sheet'. Of the 109 lunar missions during the period, 61 were successful and 48 had failed, it stated. From 1958 to 2019, India as well as the US, the USSR (now Russia), Japan, the European Union, China and Israel launched different lunar missions -- from orbiters, landers and flyby (orbiting the Moon, landing on the Moon and flying by the Moon). The first mission to the Moon was planned by the US in August 17, 1958, but the launch of Pioneer 0 was unsuccessful.

What has really gone wrong is difficult to predict now: Former ISRO chief

"If you start listing, there are at least ten points where it could have gone wrong. What has really gone wrong is difficult to predict now", he said. "Only thing is in the last ten seconds (of the mission), there was a deviation in the trajectory and velocity path. Looking at the data available till that point I am sure ISRO will be able to identify (where things went wrong)," he added.

It's disappointing for all of us: Former ISRO chief on Chandrayaan-2

Nair also said that the lander's contact-loss was highly disappointing, and he never expected such a scenario. "It's disappointing for all of us. The entire country was looking forward to it." He said the entire mission -- from the launch till the lander lost its communication with ground-stations at an altitude of to 2.1 km from the Moon's surface -- went like text-book precision. "When you look at operation 2.1 km down below, it's really complex; half of us were keeping our fingers crossed because there are several instruments and thrusters will have to work very precisely; only then the final objective can be achieved," the former ISRO Chief said.

Orbiter is in space and it should do an excellent job of mapping: Madhavan Nair

Chandrayaan-2: What Dr Abdul Kalam said on failure after ISRO’s SLV-3 mission crashed

Even though Vikram lander of the Chandrayaan-2 failed to make a smooth soft-landing, unable to bring down its speed to the required level, one cannot help but remember former President APJ Abdul Kalam’s words on how to face failures while he was speaking about an incident that happened in 1979 during SLV-3 satellite launch that was a failure. Abdul Kalam was then the project director of India’s first Satellite Launch Vehicle (SLV-III) and Professor Satish Dhawan was the chairman of ISRO. Read More

Chandrayaan-2 landing attempt will help India's future missions: Former NASA astronaut

The lessons learned from India's “bold attempt” to soft land Chandrayaan-2's Vikram module on the lunar surface will help the country during its future missions, former NASA astronaut Jerry Linenger said on Saturday. Linengar, who flew on Russian space station Mir that operated in low Earth orbit from 1986 to 2001 for five months, took take part in the live telecast of Chandrayaan-2 landing attempt on the National Geographic Channel. "We should not be too discouraged. India was trying to do something very, very difficult. In fact, everything was going as planned as the lander came down," Linenger told PTI in an email interview. Linenger noted that the lander "unfortunately" never quite made it to the hover point – which is an altitude of about 400 metres above the lunar surface. "...if it had made it to that point, and even if it had not succeeded beyond that, it would have been helpful because the radar altimeters and lasers could have been tested. But if you step back and look at the big picture, this (attempt) would obviously be very helpful for follow on missions," he said.

Chandrayaan-2 Moon Landing Highlights:

India’s dream of landing a spacecraft on moon lay shattered as the Vikram lander of the Chandrayaan-2 failed to make a smooth soft-landing, unable to bring down its speed to the required level.

To decelerate after starting its descent, Vikram continuously fired its four thrusters in the direction of its movement. It travelled a total of almost 585 km in a parabolic path before losing contact. Before the touchdown, a few hundred kilometres from the ground, it was expected to hover over the surface, trying to ascertain whether there was a safe place to land.

Chandrayaan-2 was India’s first attempt at landing a spacecraft on the moon. Only three countries — the United States, the erstwhile USSR and China — have managed to place a spacecraft on Moon so far.

Chandrayaan-2, riding the powerful GSLV Mk-III rocket, was successfully launched at 2.43 pm on July 22 from the Satish Dhawan Space Centre at Sriharikota. It was a textbook launch and initial anxiety evaporated 16 minutes 23 seconds later when scientists at mission control broke into applause, signalling that Chandrayaan-2 was now on its own.

ISRO Chairman K Sivan had repeatedly been describing Friday's Moon landing as "the most terrifying 15 minutes” of its journey. If successful, this would have been India’s first soft landing on the moon’s surface. Only the US, the former USSR and China have been successful in landing humans or machines on the moon.

India's mission to look for water on the Moon stemmed from the discover of Chandrayaan-1, which found its presence in 2008.
