mission chandrayaan 2

what is chandrayaan 2?

Chandrayaan 2 was a very daring lunar mission for India because Indian is the first country that wants to land its spaceship in the south polar region of the moon. The basic goal of this mission was that India could understand the moon by them self.

mission chandrayaan 2


What is the purpose of Chandrayaan 2?

Chandrayaan 2, 22 July 2019 ko was launched from Satish Dhawan Space Center at 2:43 pm, the mission was to study elements of the moon's surface. Now the question comes, why only on the moon?. because The moon provides very good linkage to the Earth's earlier history and our solar system too. To study the moon's origins, our Space Rover will land on the South pole of the moon. Now the question is why in the south pole only? The South Pole is very unique because it is much bigger than the North Pole, the greater part of it is hidden in the shadow, due to the shadow it is more capable of getting water here and many solar resources of our solar system. There is a chance to meet fossil resources of the earlier solar system Unlike Chandrayaan 1, this mission was about to recirculate the moon's surface very closely. Has been very strategically planned for watering the moon and to explore the moon's surface more thoroughly.

what makes chandrayaan 2 so special?

here are the few regions which make the chandrayaan 2 so special

1.The first earth mission to land comfortably on the south pole of the moon.

2.India's first mission to land on the moon, which is made of India's technology.

3. the fourth country of the world which will land well on the moon.

how many launchers and spacecraft in the chandrayaan 2 mission?

Their Are One Launcher and three spacecraft in this mission 

 1. The GSLV Mk-III launcher, the most powerful launcher of today in India and it has been designed and fabricated in India.
2. the orbiter, who is observant will observe the top part of the moon and will keep communication with the Earth with the rover.
3. Vikram Lander has been built to make soft-land on the surface of the moon.
4.pragyan rover, Has been made to explore  the surface of the moon and find the important information on the surface of the moon, there are 4 wheels inside this rover, which are moving under the help of AI (artificial intelligence) and they get peace with the help of solar power to do their work, the weight of this rover is 24 kg.


Timeline of the mission

in 2008 the prime minister of India DR Manmohan Singh approved the chandrayaan 2 projects. Chandrayaan 2 is launched from the earth on 22 July 2019, it took 11 years to complete this mission, on 7th September 2019 Chandrayaan was supposed to land on the moon, but when the lander fell on the moon, it reached its balance And then the connection of India and Chandrayaan 2 was closed with a hitch.

Chandrayaan 2 mission had 3 phases in reaching from the earth to the moon,

launch-

Chandrayaan 2 was to be launched on the first day of July 14, 2019, but due to which technical problem was not possible before the launch of 56 mints and 25 seconds, the launch was again done on 22 July 2019. This succumbed comfortably to the orbit of the earth

Geocentric phase-

After the earth reached the orbit the Chandrayaan-2 spacecraft stack gradually raised its orbit using onboard propulsion over 22 days. In this section, one perigee-elevating and 5 apogee-elevating burns have been completed to attain a particularly eccentric orbit of 142,975 × 276 km accompanied by way of trans-lunar injection on 13 August 2019Such an extended Earth-sure segment with multiple orbit-raising maneuvers exploiting the Oberth impact turned into required due to the limited lifting ability of the launch vehicle and thrust of the spacecraft's onboard propulsion gadget. A similar method turned into used for Chandrayaan-1 and the Mars Orbiter Mission for the duration of their Earth-certain section trajectory.



Selenocentric phase-

Just 29 days after launch, when the Chandrayaan 2 spacecraft enters the orbit of the moon, the next day on August 20, 2019, when the orbit of the spacecraft moon makes an orbit, it does well after that The 3-spacecraft stack becomes positioned into an elliptical orbit that passes over the polar regions of the Moon, with 18,072 km (eleven,229 mi) aposelene and 114 km (seventy-one mi) periselene. By 1 September 2019, this elliptical orbit changed into made nearly round with 127 km (seventy-nine mi) aposelene and 119 km (74 mi) periselene after four orbit-decreasing maneuvers observed by using separation of Vikram lander from the orbiter on 7:45 UTC, 2 September 2019.

planing landing sit-

The two landing sites were selected from where Chandrayaan 2 was to land, which is the South Pole Aitken basin.

mission chandrayaan 2

failed landing-

Vikram separated from Chandrayaan-2 on 7 September 2019 and turned into scheduled to land at the Moon at around 1:50 a.M. IST. The initial descent turned into taken into consideration within assignment parameters, passing essential braking tactics as predicted. The descent and gentle-touchdown have been to be accomplished through the onboard computer systems on Vikram, with assignment manipulate not able to make corrections.

The lander's trajectory started to deviate at approximately 2.1 kilometers (1.3 mi; 6,900 feet) above the surface. The very last telemetry readings during ISRO's live-flow show that Vikram's final vertical speed was 58 m/s (210 km/h) from 330 meters above the surface which, consistent with the MIT Technology Review, is "quite fast for a lunar landing." Initial reports suggesting a crash had been showed by ISRO chairman K. Sivan, mentioning that the lander area had been observed, and "it must have been a hard landing". Sivan has tasked senior scientist P. S. Goel to move the Failure Analysis Committee to inspect the reasons for the failure. The orbiter a part of the assignment, with eight medical contraptions, stays operational and will preserve its seven-12 month's challenge to examine the Moon.

After this sad incident, the scientist of Sub India was heartbroken, but whatever happened, this mission was a very proud mission for India, which the Scientist of India tried his best to fulfill, hoping that India We have seen more successful missions like this, thanks for reading this article
