๐ฉLVM has successfully injected "Chandrayaan 3 "
๐in the precise orbit , proving again to be the most reliable heavy-lift vehicle launch by ISRO.
๐Launching date -14th july 2023 at 2:35 PM.
๐Launchpad- Satish Dhawan Space Center (Shriharikota) Andhra Pradesh.
๐Rocket- LVM 3{Launch Vehicle Mark -III}
๐Bus- Chandrayaan
๐ ₹ 650 crore
๐Time duration to reach moon- 42days.
๐Objective:- The three main objectives of this ₹615 crore mission is
๐ Safe and soft landing on the Moon,
๐To demonstrate the Rover roving on its surface
๐To study environment in moon 's south pole.
๐ฑ Constituents:-
๐The Chandrayaan-3 consists of an indigenous propulsion module (PM), lander module (LM).
๐The propulsion module will carry the lander (containing the rover) from the EPO around earth to a circular orbit around the moon, at an altitude of 100 km. This module also carries instrument called ‘Spectro-polarimetry of Habitable Planetary Earth’ (SHAPE), to study spectral emissions coming from earth.
๐Key Components
๐Chandrayaan-3 has 3 important parts on which this mission is based on,they are
๐ a 1726 kg lander,
๐26 kg rover
๐2148 kg propulsion module.
๐ Key Functions
๐The function of the propulsion module is to change the trajectory of the lander and the rover and take the spacecraft from the earth and place it in a fixed orbit.
๐The lander will then land the spacecraft on the surface of the moon and the rover will come out and explore the lunar surface.
๐กAbout the project
๐The lander is named as 'Vikram' (after Vikram Sarabhai, the father of the Indian space programme)
๐The rover's name is 'Pragyan' from Sanskrit for wisdom.
๐The launch of Chandrayaan-3 took place at 14 July 2023, at 2:35 pm IST.
๐The lunar injection was of 100 km which was a circular polar orbit .
๐This was the first part of phase -I which was completed successfully.
๐Mission duration
Vikram lander: ≤ 14 days (planned)
Pragyan rover: ≤ 14 days (planned)
๐The lander and the rover is expected to land near the lunar south pole region on 23 August 2023 .
๐The lunar south pole region features craters that are unique in that the near-constant sunlight does not reach their interior.
๐The craters are cold traps that contain a fossil record of hydrogen, water ice, and other volatiles dating from the early Solar System.
๐Solar power, oxygen, and metals are abundant resources on the Moon.
๐Elements known to be present on the lunar surface include, among others, hydrogen (H), oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminium (Al), manganese (Mn) and titanium (Ti).
๐Why it is difficult to land at south pole at moon?
๐The polar regions are tricky because many parts are in complete darkness at all times and there is never any sunlight, with temperature touching -230 degree Celsius. These conditions can make the operation of instruments difficult, along with the presence of large craters that are as huge as thousands of kilometres.
๐ฑ Discoveries so far
๐India has launched two lunar missions before "chandrayaan 3 ".
๐First of its kind was "Chandrayaan 1" launched on October 22, 2008 with the mission to discover water on the moon .
๐ "Chandrayaan-2" was launched after the 1st Chandrayaaan mission on July 22, 2019, in which the lander made it to the lunar orbit, but later it lost connection with isro just 2.1 km above the moon's surface.
๐And Now, this is our 3rd Chndrayaan mission on "south pole of moon" for the discoveries of moon's environment and its constituents.
