On July 22, 2019 in Andhra Pradesh Satish Dhawan at Sriharikota Space Center (Satish Dhawan Space Centre SHAR: SDSC -SHAR) of Chandrayaan 2 spacecraft to geosynchronous satellite launch vehicle (GSLV) Mark III has been launched successfully.
Chandrayaan 2 Essay in 700 words:
The spacecraft is currently circling around the Earth at 169.7 km closest to the Earth and 45,475 km from the Earth, this flight is the first operational flight of GSLV Mark III.
It is notable that it was to be launched on July 15, 2019 but due to some technical problems it was stopped a few hours before the launch.
Soon after the spacecraft was separated from the launch vehicle, the Solar Array of the spacecraft i.e.
The solar array was deployed automatically and the ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore successfully controlled the spacecraft.
In the coming days, this process will be conducted in an orbit in a systematic manner using Chandrayaan 2 onboard propulsion system.
GSLV Mark-III:
GSLV Mark III is a high-impulse vehicle developed by ISRO, through which India’s 4-tonnes geosynchronous satellites can be placed in orbit.
Thus India will become completely self-sufficient in terms of satellite launch.
The GSLV Mark III has a height of 43.43 meters and a lift-off mass of 640 tonnes, with three stages using the indigenous cryogenic engine ‘CE-20’.
Lately in November 2018, the GSLV Mark-III D2 launch vehicle was used to orbit the GSAT-29 communication satellite.
ISRO presently has the capability to launch payloads of up to 2.2 tonnes only and they have to rely on foreign countries to launch greater than this load.
GSLV Mark-3 will be the most powerful launch vehicle in India capable of placing four tons of communication satellites in geosynchronous orbit with an altitude of 36,000 km.
It is known that at present, GSLV Mark-II has a capacity of about 2 tonnes.
An essential function of the GSLV Mark III is that it makes use of the third stage of the Indian cryogenic engine and has increased payload capacity than the present GSLV.
Chandrayaan-2 Campaign- Chandrayaan 2 Essay:
This is India’s second mission to the moon.
It makes use of a totally indigenous orbiter, Lander (Vikram) and Rover (Pragya), the Rover (Pragya) is situated inside the Lander (Vikram).
The mission of the Chandrayaan-2 mission is to develop and execute key technologies including moon mission capability, soft-landing on the moon and moving on the lunar surface.
The information obtained by this mission will improve the understanding of the origin and evolution of the moon by studying the geographical location of the moon, mineralogy, surface chemical composition, temperature, geographical properties and circumference.
After leaving Earth’s orbit and entering the Moon’s sphere of influence, the propulsion system of Chandrayaan 2 will be ignited to reduce the speed of the vehicle, this would enable it to enter the Moon’s primary orbit.
After this, a circular orbit of Chandrayaan-2 will be established 100 kilometers above the lunar surface under many technical works.
The lander separated from the orbiter and traveled 100 km, the lander will perform a soft-landing on the Moon’s South Pole on September 07, 2019, after several complex technical procedures.
The rover will then separate from the lander and take a look at for one day (14 days on Earth) on the lunar surface.
The tenure of the lander can also be equal to 1 lunar day and the orbiter will proceed its mission for an interval of 1 yr.
Other Memorable facts of Chandrayaan 2:
- The weight of the orbiter is about 2,369 kg, while the lander and rover weigh 1,477 kg and 26 kg respectively.
- The rover can travel up to 500 meters. For this, it will draw energy from the solar panel in the rover.
- Chandrayaan-2 also has many payloads which will give detailed information about the origin and evolution of the Moon.
- The orbiter has 8, the lander has 3 and the rover has 2 payloads.
- The orbiter payload will be sensing report from the 100-km orbit, while the lander and rover payload will perform measurements near the landing site.

Conclusion for Chandrayaan 2 Essay:
The third important dimension of Chandrayaan-2 mission is the technology installed on Earth.
Through them, scientists will be able to get information about data and all instruments from spacecraft, it will also send radio instructions to the spacecraft.
It includes technical features on Earth’s Chandrayaan-2 are Indian Deep Space Network, Spacecraft Control Center and Indian Space Science Data Center.
