Chandrayaan 2: the launching story of Chandrayaan 2 by ISRO

India is taking another high jump towards the space with its upcoming chandrayaan 2 mission which would held on July 15th 2019, chandrayaan 2 who is the moon mission which will launch on 15th of July 2019 at 2:41 a.m. from India.

About Mission

There are 14 payloads which Chandrayaan-2 will be carrying to the Moon, in which 13 of them are indigenous payloads and one “passive payload” of Nasa. Isro's ( Indian space research organisation) chairman K Siwan announce, “Nasa’s passive payload, which is Laser Retroreflector (LRA), integrated with Vikram lander, will be “carried for free” and help calculate the distance between the earth and the Moon. It will additionally find the accurate location of the lander on the Moon. This Nasa payload will work for long (even after the moonlanding) and Nasa will share the data generated from this payload with us.” He said, “As this mission is an inter-planetory mission, data from our Deep Space Network in Byalalu (Karnataka) won’t be sufficient. We will so use Nasa’s network of deep space centres for Navigation and tracking of our Chandrayaan-2 module throughout its journey to the moon. Nasa will make use of their network and not just one place (space hub) for navigation and tracking.” Nasa’s deep space Network (DSN) is a worldwide network of us spacecraft communication facilities, situated in US’s california, Spain’s madrid and Australia’s canberra, that supports US Inter-planetory spacecraft missions. It conjointly performs radio and radiolocation astronomy observations for the exploration of the solar system and therefore the universe. Nasa had also joined hands with Isro during India’s first moon mission. Chandrayaan-1, which was launched in 2008, also carried a Nasa payload, Moon Minerology Mapper (M3). M3, an imaging mass spectrometer, helped confirm the discovery of water locked in minerals on the Moon. Nasa had then credited India’s Chandrayaan-1 mission for the biggest discovery on the Moon. The find also raised the possibility of setting up human habitat on the earth’s only natural satellite. Interestingly, Nasa scientists, in a recent discovery this year, have confirmed that water is being released on the lunar surface during meteor showers. In a four-minute video revealed by NASA Goddard alludes to India’s Chandrayaan-1 lunarcraft, that helped the us space agency make sure the presence of frozen water deposits on the lunar surface.

India’s second odyssey to Moon

https://youtu.be/0knAOPYHX08 On July 15, the integrated module involving an orbiter, lander and a rover will be launched by an advanced version of the GSLV MK III rocket from the Sriharikota launch centre. Once released by the rocket in the geo-transfer orbit, the integrated Chandrayaan-2 module will move in an elliptical orbit around the Earth for 16 days when five orbit-raising manoeuvres will be conducted. It will then spend five days to finally reach the Moon’s orbit in around 20-21 days (August 5 or 6) after covering a distance of 3.84 lakh km from the Earth. Thereafter, the integrated module will remain in the lunar orbit for 27 days before the lander named Vikram gets separated. Vikram, which will house rover Pragyan, will sit on top of the orbiter. Once the lander is 30km from the Moon, it will descend for the touchdown. “The 15-minute operation in which Vikram makes the final descent and soft-lands will be the most complex mission,” the Isro chief said. After a successful landing, Pragyan will come of the lander and move at a speed of 1cm per second on the lunar surface to cover a distance of 500 metre in 14 earth days. During the 14 earth days, it will carry out different scientific experiments with its two payloads. “The rover will take images of the Moon and analyse the content on the lunar surface and send data and images back to the earth through the orbiter within 15 minutes,”.

About chandrayaan 1: short summary

Chandrayaan-1 was the India's first lunar probe. It was launched by the Indian Space Research Organisation ISRO in October 2008, and operated until August 2009. This mission included a lunar orbiter and an impactor. India launched the spacecraft using a PSLV-XL rocket, serial number C11, on 22 October 2008 at 00:52 UTC from Satish Dhawan Space Centre, at Sriharikota about 80 km (50 mi) north of Chennai. The mission was a major boost to India's space program, as India researched and developed its own technology in order to explore the Moon. The vehicle was inserted into lunar orbit on 8 November 2008. https://youtu.be/_9JxSrwlTA4 Read the full article
