AGENCYSRIHARIKOTA: Aiming to take a “billion dreams” to the moon, India on Monday successfully launched its second lunar mission Chandrayaan-2 onboard its powerful rocket GSLV-MkIII-M1 from the spaceport here to explore the uncharted south pole of the celestial body by landing a rover. The geosynchronous satellite launch vehicle lifted-off from the Satish Dhawan Space Centre here into cloudy skies at 2.43 pm and successfully placed the 3,850-kg Chandrayaan-2 into the earth orbit about 16 minutes later. The mission’s success brought in huge relief for ISRO scientists after the July 15 launch was called off just about an hour left following a technical glitch in the rocket.
PM, opposition hail launchNew Delhi: President Ram Nath Kovind, Vice President Venkaiah Naidu, Prime Minister Narendra Modi and leaders across party lines on Monday hailed the launch of India’s second lunar mission Chandrayaan-2 from the spaceport in Sriharikota.These leaders also congratulated the ISRO scientists and engineers for the “historic launch”, and said it was a proud moment for all Indians. The mission is expected to lead to new discoveries and enrich India’s knowledge systems, Kovind said. In a series of tweets, Modi said every Indian is immensely proud today. Referring to the indigenous systems used in Chandrayaan-2, he said the mission is “Indian at heart, Indian in spirit!…Efforts such as Chandrayaan-2 will further encourage our bright youngsters towards science, top quality research and innovation.”The Prime Minister also shared pictures of him watching the launch on a large screen and shared his audio message to the Indian Space Research Organisation (ISRO) after the successful launch.Congratulating the ISRO, BJP President and Home Minister Amit Shah said they have set another benchmark in the field of space technology and that a grateful nation is proud of the ISRO scientists.“I also thank PM Modi ji for encouraging our institutions for setting new standards every time,” Shah said in a tweet.Congress hailed team ISRO for the successful launch of Chandryaan2, but also sought to claim credit for India’s advancement in space exploration, citing the contribution of its Prime Ministers.“This is a good time to remember the visionary move of India’s first PM Pandit Jawaharlal Nehru to fund space research through INCOSPAR in1962 which later became ISRO. And also Dr. Manmohan Singh for sanctioning the #Chandrayan2 project in 2008,” the party said in a tweet from its official Twitter handle.Congress’ chief spokesperson Randeep Surjewala also hailed the launch, saying India’s tryst with destiny continues.“There are defining moments like these that make us a great nation. My gratitude to all scientists and space engineers at ISRO who have toiled day & night to make 130 Cr Indians proud!” he said in a tweet.A day before the launch, senior Congress leader Anand Sharma had said India’s space journey began with Pandit Jawaharlal Nehru and took a giant leap in 1975 with the launch of Aryabhat, led by “charismatic PM Indira Gandhi”.“ISRO has many notable achievements including Chandrayaan (2008) and Mangalayaan (2013). Wishing Team ISRO all the best for Chandrayaan2,” he had said in a tweet.Defence Minister Rajnath Singh on Monday said team ISRO scripted a new chapter in India’s space history with the launch of this ambitious and indigenous Mission to moon.“Today’s launch of Chandrayaan 2 reflects India’s growing prowess in space technology. Congratulations Team!,” Information and Broadcasting minister Prakash Javadekar said.BJP’s working president J P Nadda also hailed the lauched and congratulated ISRO scientists for making Indians proud.Delhi Chief Minister Arvind Kejriwal said the country is proud of the historic achievement of ISRO scientists.Former President Pranab Mukherjee said the launch was an extremely proud moment for the nation.“Having closely observed Chandrayaan1 & MOM (Mars Orbiter Mission) in the Govt, I commend our brilliant scientists at ISRO for their stupendous progress over the years,” he said.The geosynchronous satellite launch vehicle lifted-off from the Satish Dhawan Space Centre at 2.43 pm and successfully placed the 3,850-kg Chandrayaan-2 into the earth orbit about 16 minutes later.
The Rs 978 crore mission, that will mark a giant leap in India’s space research and make it only the fourth country to have landed a rover on Moon, was rescheduled to Monday after scientists corrected the technical glitch in the three-stage rocket.
In a textbook launch, the towering GSLV-MkIII-M1 lifted off majestically from the second launchpad at the Satish Dhawan Space Centre here, over 100 km from Chennai, as the Indian Space Research Organisation scientists broke into jubilation.
Scientists led by ISRO chief K Sivan watched the launch sequence in rapt attention and broke into applause after every key stage of the rocket’s flight which progressed precisely as programmed.
A visibly relieved Sivan, who announced the success of the mission, said “it is the beginning of a historical journey of India towards the moon.”
“We bounced back in flying colours after the earlier technical snag,” he said about the glitch that made the space agency reschedule the Chandrayaan-2 launch from July 15 to Monday.
There will be 15 “very crucial manouvres” in the next one and half months before the satellite is brought around the moon, he said in his post-launch address from mission control centre.
“After that the D-Day will come and on that day we are going to experience 15 minutes of terror, to ensure the landing is safely near the South Pole,” he added.
ISRO had last week called off the launch with just 56 minutes of the countdown left, a decision that was later hailed by space experts as a prudent measure not to risk the mission.
After taking remedial action based on an analysis carried out by a team set up to look into the snag, the space agency announced the rescheduled lift-off four days ago, indicating the confidence of the scientists which stood vindicated with the successful launch.
“Chandrayaan 2 is ready to take a billion dreams to the moon now stronger than ever before! Join us for the launch on Monday 22 July, 2019 at 2:43 PM IST,” ISRO had tweeted on July 18 while announcing the rescheduled launch.
Chandrayaan-2 comes 11 years after ISRO’s successful first lunar mission Chandrayaan-1 which scripted history by making more than 3,400 orbits around the Moon and was operational for 312 days till August 29, 2009.
The 43.43m tall three stage rocket GSLV-MkIII-M1 dubbed as ‘Baahubali’ for its ability to carry heavy payloads, successfully placed the Chandrayaan-2 in the Earth orbit, ISRO said.
Chandrayaan-2, a three-component spacecraft comprising an orbiter, lander and a rover, will undergo 15 crucial manoeuvres before landing on the Moon, expected by the first week of September.
Scientists would make a soft landing of the lander in the South Pole region of the moon where no country has gone so far.
Billed as the most complex and prestigious mission undertaken by ISRO since its inception, Chandrayaan-2 will make India the fourth country to soft land a rover on the lunar surface after Russia, the United States and China.
About 16.20 minutes after the lift-off, the GSLV rocket placed Chandrayaan-2 into 170 km x 39059 kms Earth orbit.
From here onwards, the mission will undergo a series of manoeuvres by scientists to carry out different phases of the mission over the next 48 days.
Subsequent to the rescheduling of the launch, the space agency has tweaked the orbital phases, increasing Earth-bound phase to 23 days as against 17 days planned originally.
At the end of the Earth-bound phase, the orbit of the spacecraft will be finally raised to over 1.05 lakh km before nudging it into the Lunar Transfer Trajectory taking it to the proximity of Moon in the next two days.
Then gradually over the next few days it will be brought to 100 X 100 km circular orbit when the lander will separate and after another few days of orbiting it will make a soft landing at a chosen place on the Lunar surface.
The soft landing of the lander – Vikram carrying rover ‘Pragyan’, one of the toughest phases of the mission and described by the ISRO chief as “15 minutes of terror (filled moments), would be attempted between September 6-8.
“Chandrayaan-2 is the next leap in technology as we attempt to soft land close to South Pole of Moon. The soft landing is extremely complex and we will experience approximately 15 minutes of terror,” Sivan had said.
The mission, which carries a total of 13 payloads, including three from the Europe, two from the US and one Bulgaria, seeks to improve understanding of the moon which could lead to discoveries that will benefit India and humanity as a whole.
A Laser Retroreflector Array (LRA) of US space agency NASA is among the payloads and is aimed at understanding dynamics of Earth’s moon system and deriving clues on Lunar interior.
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.
The lander ‘Vikram’, named after father of Indian space research programme Dr Vikram A Sarabhai, carrying the rover ‘Pragyan’, will be landed in a high plain between two craters at a latitude of about 70 degrees South of the moon.
Then the 27-kg ‘Pragyan’ meaning ‘wisdom’ in Sanskrit and a six-wheeled robotic vehicle, will set out on its job of collecting information on lunar surface.
A safe site free of hazards for landing would be decided based on pictures sent back by the camera onboard the lander and after touchdown the rover will carry out experiments for 14 Earth days, equals one Lunar Day.
The launch was witnessed by nearly 5,000 people who were accommodated at a viewing gallery, located a few kms from the launchpad, thrown open to the public by the ISRO in May last.
