Special features of GSLV-Mk 3 – ISRO gave its ‘Bahubali’ the responsibility of lifting Chandrayaan-2 on its shoulder and towards the moon. ‘Bahubali’ is the most powerful rocket in ISRO. Its real name is Jieronschronus satellite launch vehicle-mark 3 (GSLV-MK3).
This rocket is capable of carrying a satellite weighing four tons. The rocket weighs 640 tons and its height is 43.43 meters. Let us know about other technical aspects related to the mission and their role.
Orbiter: The orbiter weighing 2,379 kg will orbit the moon for one year. It has eight payloads, which will carry out different experiments. This orbiter will be able to contact the Indian Deep Space Network (IDSN) in Bangalore. Apart from this, it will also be in contact with the lander.
Lander Vikram: The 1,471 kg lander has been named after Vikram Sarabhai, the father of Indian Space Science. It has three payloads. It will land on the surface of the moon at a speed of 2 meters per second. It has been prepared to work on the moon for a period of one day.
According to the Earth, this period will be 14 days. This lander will be able to connect with IDSN in Bangalore as well as orbiter and rover.
Rover Pragyan: The name of Rover Pragyan is derived from Sanskrit, which means knowledge is there. The rover weighing 27 kg has two payloads. It is a robotic vehicle with six wheels. With the help of solar energy, it can run at a speed of one centimetre per second.
It is also designed to work on a day of the moon i.e. equivalent to 14 days of earth. Throughout this period, it will cover a total distance of 500 meters on the lunar surface.
Special features of GSLV-Mk 3 1st – Campaign payload
A total of 14 payloads are included in the second lunar mission. Of these, eight are on a payload orbiter, three on a payload lander and two on a payload rover. The responsibility of carrying out an important scientific experiment in every payload will remain.
Apart from these, there will also be a laser retroreflector array (LRA) payload. This will give information about the internal structure of the moon.
Special features of GSLV-Mk 3 – 2nd Orbiter’s Payload
- Terrain Mapping Camera: This camera will form the digital Elevation model of the whole moon.
- Large Area Soft X-ray Spectrometer: will test the components of the lunar surface.
- Solar X-ray Monitor: Solar will provide input of the X-ray spectrum.
- Imaging IR spectrometer: Will collect data of minerals and find evidence of the presence of ice.
- Synthetic aperture radar L&S bands: will probe the polar region and gather evidence of the presence of ice below the surface.
- Atmospheric composition explorer-2: will study the atmosphere of the moon.
- Orbiter High-Resolution Camera: Take photos of the moon’s surface.
- Dual Frequency Radio Science Experiment: Will study the moon’s ionosphere.
Special features of GSLV-Mk 3 3rd – Landor’s payload
- The instrument for Lunar Seismic Activity: Find out a seismic activity on the landing site.
- Surface Thermo Physical Experiment: Thermal conductivity of the moon will be studied.
- Langmuir Probe: Will study the lunar surface.
Special features of GSLV-Mk 3 4th – Payload of the rover
- Alpha Particle X-ray Spectrometer: Will analyze the components on the surface of the moon.
- Laser-induced breakdown spectroscopy: Check the presence of various components around the landing site.
