Chandrayan 2: Summary
Chandrayan 2, the second lunar mission by ISRO after Chandrayan 1, consists of a lunar orbiter, the Vikram lander, and the Pragyan lunar rover which were all made in India. Chandrayan 2 mission had a cost of total ₹978 crore (approximately US$141 million). The mission was launched to the moon from the Satish Dhawan Space Centre on Sriharikota Islands on 22 July 2019 at 2.43 PM IST (09:13 UTC) by a Geosynchronous Satellite Launch Vehicle Mark III(GSLV Mk III).It had an approximate mass of 3,850 kg (8,490 lb).
The Spacecraft reached the Moon’s orbit on 20 August 2019 and began orbital positioning for the landing of Vikram lander. Vikram and the rover were planned to land on the near South polar region at around 1:50 am on 7 September 2019. The Lander Vikram along with the Rover Pragyan detached from the orbiter on 7:45 UTC, 2 September 2019.
It was expected that the Vikram will complete its journey around 1:53 am on September 7, 2019. However at 1:52 am the the lander deviated from its intended trajectory at around 2.1 kilometres (1.3 mi) from landing and communication was lost. Though ISRO has not officially confirmed that the Lander has crashed but most of the Space Scientists, experts, researchers opined that the Lander has crashed. The last 15 minutes were the most important part of this Chandrayan 2 mission and this was rightly called as “15 Minutes of Terror”. But the orbiter part of the mission, having 8 instruments is working absolutely good and so will give the studied information for coming 1 year.
On this occasion Prime Minister Narendra Modi tried to encourage ISRO’s Scientist and addressed the nation. He said, “There are no failures in Science, only experiments and experiences.” ISRO’s Chairman Dr. K. Sivan became emotional and Prime Minister cheered him.
Apart from this, celebrities, Political leaders showed their support to ISRO. Chandrayan 2 mission united the whole country and a large number of people watched the landing in their Television and mobile screens.
This small disappointment has surely made everyone upset but ISRO is sure that Chandrayan 2 will in no way affect the upcoming Gaganyaan mission as both of them are totally different.While Chandrayaan-2 was meant for soft-landing of Vikram on the lunar surface, Gaganyaan’s mandate will be to send the astronauts to space and bring them back to earth safely. The further plans are to build a space station and launch interplanetary missions to Mars and Venus.
Next year, in 2020, ISRO is going to launch its Aditya-L1 mission, the mission aimed to study Sun. We hope that ISRO would be successful in their upcoming mission.
There’s no iota of doubt that our ISRO has achieved a lot and made Indians proud of it. ISRO has given us many proud moments like Mars Orbiter Mission(MOM), launching of 104 satellites in a single launch, Mission Shakti and so on. A single failure can’t let the moral of scientists down. They are fully contented and ready for the upcoming schedules and missions . In this situation we should support ISRO and should show respect to ISRO scientists.
Chandrayan 2 mission is not a failure instead it gave the scientist a lot of learning opportunities. ISRO scientist are currently dealing with the data sent by the lander, Vikram. Most probably in 2-3 days they can give an official statement about the location and condition of the lander and rover. Earlier, ISRO had told that they were thinking to launch Chandrayan 3 in 2023.
