Chandrayaan 2: Second moon mission postponed due to technical glitch

Countdown stopped at 56 minutes, 24 seconds before the launch
Chandrayaan-2 launch live updates: The launch of Chandrayaan-2, India's second mission to the moon, was postponed after a technical glitch was observed in the launch vehicle system early morning on Monday.

Less than an hour before the scheduled lift-off, the Indian Space Research Organisation (Isro) informed of the launch being put off due to the snag. "It is not possible to carry out the launch within the window," said the mission director. The new schedule will be announced later.

The launch was scheduled to have taken place at 2.51 am from the second launchpad at Sriharikota’s Satish Dhawan Space Centre (SDSC). The countdown to the launch was put on hold at 56 minutes and 24 seconds.

The technical snag was noticed when the cryogenic fuel was being loaded. The vehicle would need to be approached to assess the problem. The fuel loaded in the rocket would first have to be emptied, and then the rocket would have to be studied for further investigation. According to an Isro source, the whole process would take at least 10 days. The new schedule would likely be disclosed only after that.

The 640-tonne rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III), about 44-metre tall, is nicknamed 'Bahubali'. 

A Laser Retroreflector Array (LRA) of NASA is among the payloads and is aimed at understanding dynamics of Earth's Moon system and deriving clues on Lunar interior.

The first one was on 18.12.2014 carrying Crew Module Atmospheric Reentry Experiment. The second and third GSLV-Mk III went up on 5.2.2017 and 14.11.2018 carrying communication satellites GSAT-19 and GSAT-29 respectively. Interestingly, GSLV-Mk III will be used for India's manned space mission slated in 2022.

Had heard about Moon in grandma's stories, say kids after visiting ISRO station

For a brother-sister twin from Jammu, the Moon had always been about the stories they had heard from their grandmother: a friendly celestial body so far away that they could only imagine to reach there some day. Not anymore, they said.
 
Swapnil and Swapnila, both Class 10 students, this week visited the ISRO station in Andhra Pradesh and saw the massive rocket that will spark their lunar imagination into reality. There, they heard stories about the Moon again, but they would have surely missed the warmth of their grandma's storytelling.

The Washington Post on Chandrayaan 2

The Washington Post, in an article titled 'India's Moon mission signals country's growing space ambitions', writes: "Although India's space program began as early as the 1960s, it has gained new prominence under Prime Minister Narendra Modi... Modi has promoted the space program as a symbol of the country's rising stature internationally and a bulwark of its defense capabilities."
 
"India's first Mars satellite cost less than the budget of the space movie, 'Gravity'. At $141 million, the cost of the current lunar mission is far less than the $25 billion spent by the United States on its Apollo program," the Post says.

Key things to know about Chandrayaan 2

India is all set to launch its most prestigious and complex space mission Chandrayaan-2. The mission will make India the fourth country to soft land on the lunar surface after Russia, the United States and China.

Here are the key things to know about India's second unmanned mission to the moon:

'15 minutes of terror'

“The last 15 minutes to the landing are going to be the most terrifying moments for us,” ISRO Chairman K. Sivan told media on Wednesday about the moon mission.

Chandrayaan 2 orbitor: key facts


Pragyan rover: All you need to know in graphics

The rover, Pragyan (also Pragyaan), is a 6-wheeled vehicle with a mass of 27 kg that runs on 50 W of solar power and can travel up to 500 m at a speed of 1 cm per second. The rover communicates directly with the lander. the rover will hold cameras, alpha-proton X-ray spectrometer, and a laser-induced ablation spectroscopy experiment.



All you need to know about Chandyaan 2's orbitor

The Chandrayaan 2 orbiter is a box-shaped craft with an orbital mass of 2379 kg and solar arrays capable of generating 1000 W power. The orbiter communicates with the Indian Deep Space Network and the lander. The orbiter will have a scientific payload comprising a visible terrain mapping camera, a neutral mass spectrometer, a synthetic aperture radar, a near infrared spectrometer, a radio occultation experiment, a soft X-ray spectrometer and solar X-ray monitor.

Objectives of Chandrayaan-2

The primary objective of Chandrayaan-2 is to demonstrate the ability to soft-land on the lunar surface and operate a robotic rover on the surface. Scientific goals include studies of lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.

How many countries have till now launched Moon Missions?

India will be the fourth nation apart from US, USSR and China to reach the moon. But, we will be the first country to explore the Lunar South Pole.

Mission Mangal actor Akshay Kumar fetes Chandrayaan- 2 women

With the Project Director and the Mission Director of India's upcoming second moon mission Chandrayaan- 2 being women, actor Akshay Kumar has sent his best wishes to the scientists for the launch.

"India's second space mission to the moon, Chandrayaan-2 is led by two women scientists of Indian Space Research Organisation (ISRO), a first in India's history. Sending my best to the rocket women and ISRO team, more power to you," Akshay tweeted on Sunday.

On the work front, Akshay is gearing up for the release of "Mission Mangal", which is based on the Mars Orbiter Mission (MOM), or the Mangalyaan project to put a space probe into Mars' orbit, launched by ISRO in November 2013.




But why the South Polar region of the Moon?

According to ISRO, the lunar South Pole is an interesting surface area which remains in shadow than North pole. There is a possibility of the presence of water in permanently shadowed areas around it, the agency said, adding craters in the South Pole region have cold traps and contain fossil record of the early solar system.

Chandrayaan-2 is a shining example of Apollo 11's legacy

Fifty years ago, on July 20, 1969, the Apollo 11 Mission landed two men on the moon. That was the culmination of the first era of space exploration, and it was also the beginning of a new era.
 
India has also been taking giants strides. A decade after its first mission — Chandrayaan 1 — discovered water on moon’s surface, India is set to launch Chandrayaan-2 at 2.51 am on July 15. It will be the first of its kind as it will shed light on a completely unexplored section of the moon — its South Polar region.

Chandrayaan-2 has 13 payloads

ISRO, which has planned for the landing around September 6, said the mission aims at going where no other nation has so far forayed - the Lunar South Pole and seek to improve understanding of the Moon which could lead to discoveries that will benefit India and humanity as a whole.

The Chandrayaan-2 has 13 payloads in total with eight of them in the orbiter, three payloads in Vikram and two in Pragyan. Five payloads are from India, three from Europe, two from the US and one from Bulgaria.

'Chandrayaan 2 is the country's first step in robotic space exploration'

India's second moon mission - Chandrayaan-2 - is the country's first step in robotic space exploration and hence more "complex" and "intricate", Indian Space Research Organisation's (ISRO) former Chairman K. Radhakrishnan said on Saturday.
 
"Chandrayaan-2, with an Indian Lander-Rover (Vikram-Pragyaan) combine, is India's first step in robotic space exploration and the mission is on the anvil. Obviously, this mission is more intricate," Radhakrishan, who is now Chairman, Board of Governors, IIT Kanpur, said.

Isro chairman seeks divine blessings for Chandrayaan 2

Indian Space Research Organisation (ISRO) Chairman K. Sivan on Saturday prayed at Tirumala temple here for the success of second moon mission Chandrayaan-2, which is set for launch on July 15.

Like his predecessors, who used to worship at the hill shrine before every major space mission, Sivan also sought Lord Balaji's blessings.

Sivan, who was accompanied by some ISRO scientists, visited the temple along with the replica of Chandrayaan-2 to receive the "benign blessings of Almighty", said Tirumala Tirupati Devasthanam (TTD), which manages the affairs of the famous temple.

Later he was offered a'edasirvachanam' at Ranganayakula Mandapam by Vedic pundits. Temple deputy executive officer Harindranath offered 'Theertha Prasadams' to the ISRO Chief.
