How Will Chandrayaan 3 Reach The Moon! Chandrayaan 3 or LVM 3-M4 spacecraft was successfully launched from Indian Space Agency ISRO’s Satish Dhawan Space Center on 14 July 2023 at 2:35 PM IST. The mission aims to place India’s first lander Vikram and rover Program on the lunar surface.
This mission was started in 2008. Chandra Abhiyan 1 was launched on October 22, 2008. Chandrayaan 1 was destroyed before landing on the lunar surface. As the mission was not successful, the mission was continued. On July 22, 2019, Chandrayaan 2 was launched in a new way. According to the lunar mission scientists, everything was going well with only 2.1 kilometers left to land on the moon.
But suddenly, due to some problems with Chandrayaan 2, scientists lost communication with Chandradan 2. That’s why this mission was not successful. Scientists do not give up and prepare again for Chandrajana 3. Chandrayaan 3 has been rebuilt to fix the mistakes that went wrong in the previous two failed missions. Chandrayaan III was successfully launched on 14 July 2023 at 2:30 am. Now the question is how the rover will reach the moon. In this post, I will discuss in detail today how to land on the moon and what will the Chandrayaan do when it goes to the moon.
How will Chandrayaan 3 enter the lunar orbit?
Chandrayaan 3 was launched by rocket at 2:30 PM IST. The rocket’s speed at launch was 1,627 kilometers per hour. 108 seconds after the launch of the rocket, the liquid engine of the rocket started at 45 km. After the start of its liquid engine, the rocket reaches a speed of 6,437 kilometers per hour.
Baahubali rocket carrying LVM3-M4 Chandrayaan 3 towards the moon. After 130 seconds, two booster engines on either side of the rocket will separate from the rocket at a height of 62 km. Then the rocket’s main engine starts.
After the start of the main engine, the speed of the Baahubali rocket increased to eight thousand kilometers per hour. The two separated booster rockets were thrown into the ocean by scientists with the help of software. And the main engine of the rocket moves towards the moon with Chandrayaan 3.
Then 196 seconds later, after the rocket had traveled 114.8 km, the two heat seals separated from the front of the rocket. Then after 360 seconds the liquid engine also separated from the rocket. After the liquid engine is separated from the rocket, the cryogenic engine is started from the rocket.
After this engine starts, the speed of the rocket stands at 36 thousand 9668 kilometers per hour. After some distance, the cryogenic engine shut down and Chandrayaan 3 separated. The lander then reached Earth’s orbit 16 minutes later and gradually increased its orbit towards the Moon. After being placed in Earth’s orbit, the spacecraft is flown by the Proportion Module. Chandrayaan 3 will be flown around the world for a few days first.
As it orbits the Earth, Chandrayaan 3 will gradually move away from the Earth and move towards the Moon. That is why Chandrayaan 3 will be rotated in an oval room or road instead of on a circular road. The reason for orbiting on an elliptical path is that if the spacecraft is orbiting on a circular path, the spacecraft will always travel on the same path.
An object in space is always rotated in an oval path to send it away or to pull it closer. After a few days, Chandrayaan 3 will reach the moon’s orbit. After reaching the moon’s orbit, the rover will be circled around them in the same manner on an elliptical path. Then the rover will slowly move toward the moon. After reaching the lunar orbit, the rover will orbit the moon for 13 days.
Chandrayaan III is the work of different parts
Chandrayaan 3 is carrying 3 separate parts with it. First of all, there is the Person module, which will help the spacecraft move around the moon. Number two is the lander module. Another name for the one that will land on the lunar soil is Vikram and the last number three is Rover. The work is to land on the moon take samples from different places and send them to Earth through testing.
One more part is needed here which is the orbital. Whose job is to always revolve around the moon. But that part is not sent here. That’s because the orbiter sent with Chandrayaan 2 is still orbiting the moon. So that orbital will be used here. Due to this, no new orbitals were sent.
Determination of two landing sites for Chandrayaan 3
The lander will separate from the modesty propulsion model when the rover comes within 100 km of the moon. The lander module will then move into its orbit while trying to decelerate. In order to decelerate the lander, the momentum reversal engine will be activated within the lander.
After 40 to 42 days, both the lander and the rover will land on the south side of the Moon. The landing time of the Chandrayaan on the lunar soil is fixed on August 23, 2023, at 5:47 PM. But this time may be changed based on sunrise conditions there. If there is a late sunrise then this time may be placed in September. Chandrayaan 3 Landing on the moon is one of the most difficult tasks. Because Chandrayaan 2 failed at this time.
So the last 15 minutes are considered to be the most difficult time in this campaign. Two sites have been selected to land Chandrayaan 3. If unable to land at the first location, it will be landed at the selected second location. After a proper landing on Chad, the rover will come out of the lander under the command of the scientists. The rover will then begin its operations on the lunar soil.
What is the function of the rover in Chandrayaan 3?
The rover will test the natural resources present on the moon such as water, soil, air, weather, and the presence of ice there, and send it to the earth. Various instruments have been sent in the Chandrayaan to carry out scientific tests on all these subjects. One of them is a seismometer. It will measure the moon’s earthquakes. These are fitted with solar panels to power the lander and rover on the moon.
With the help of this, they can keep themselves active by taking energy from the sun and can do the necessary tests. The rover will not collect complete data and send it back to Earth at all. For this, first, the signal will be sent from the rover to the lander. Then the signal from the lander will come to the orbital on the moon. The orbital will then send that signal back to Earth. This mission can operate for up to 14 Earth days.
Designed with that goal in mind. Because 14 days on the earth equals one day on the moon, if everything goes well then this mission will be taken further after these 14 days. Currently, ISR has only 14 days of time. If this mission is successful, India will become the 4th country after America, China, and Russia to go to the moon.
