How did India’s Chandrayaan 3 reach the Moon at such a low cost
How did India’s Chandrayaan 3 reach the Moon at such a low cost:
All planets, bodies, and stars have their own gravitational force. But this gravitational force is different for everyone, in which some planet has more gravitational force and some planet has less gravitational force. Due to which the gravitational force on objects in the orbit of some planets remains very low. On some planets, the force of gravity is so low that any spacecraft has to spend very little energy in orbiting those planets.
The gravitational force of the Moon is less than that of the Earth: due to which the weight of any objects in the Moon’s orbit or on the Moon is less. Due to which the lunar vehicle consumes very little energy.
There is a natural law of gravity: any object will move away from the planets. The gravitational force of that planet on that object keeps decreasing. And the same rule applies to the lunar vehicle also.
When the lunar spacecraft is released from the Earth, the spacecraft has to generate a lot of energy because due to the lunar spacecraft being very close to the Earth, the gravitational force of the Earth is very strong. There are many types of guides in the lunar vehicle which keep changing from time to time according to the energy requirement.
There are many types of rockets in the lunar vehicle which are connected into one. When the spacecraft leaves the Earth for the first time, a huge energy generating rocket is started. As the lunar spacecraft moves away from the Earth, the gravitational force of the Earth becomes less. In such a situation, the lunar spacecraft needs less energy. A rocket with less power than that gets started. When the lunar vehicle enters the Earth’s orbit where the gravitational force of the Earth is very low, in such a situation very little energy is required to run the Chandrayaan. Now the lunar vehicle starts rotating under the gravitational force of the same orbit of the Earth and gradually enters the Moon’s orbit.
When the lunar vehicle reaches the Moon’s orbit, the lunar vehicle starts moving near the Moon while rotating in the Moon’s orbit, then the gravitational force of the Moon pulls the spacecraft towards itself, but the gravitational force of the Moon is much less than that of the Earth, due to which the Moon But the vehicle requires very little energy to land, then the small rocket fitted in the lunar vehicle is started and the vehicle is landed on the moon. Now solar energy is used to move the lunar vehicle to the moon.
India had sent Chandrayaan 3 to the Moon by moving it in a low gravity orbit, due to which less energy was used and it took 42 days to reach the Moon. India had landed the lunar rover in the southern part for the first time.
