Chandrayan is not big achievement at all

Indake Russia friends tho matladuthuna.

They said they didn't even cared of this.

While undoubtedly we need to appreciate chadrayaan 3  success but realistically speaking indian rockets are very very weak compared to what SpaceX is building. Which is why they need multiple orbits and lighter payloads to reach moon.

NASA reached the moon in a few days with  heavy equipment, ISRO took a month and a tiny rover.

I think they are using sling shot method that they used for mangalyan 

they are able to keep the cost low , they will improve and slowly overtake NASA

How does ISRO control gravity?

It takes four days to a week for a NASA vehicle to reach on the moon. But why is it taking so long for ISRO to deliver its vehicle.

The reason for this is that ISRO does not have powerful rockets like NASA, which can take Chandrayaan-3 directly to the lunar orbit.

For this reason, ISRO takes advantage of the speed and gravity of the earth.

In simple words, understand it like this - the way when you get down from a slow moving bus or train, you get down in its direction.

In such a situation, the risk of falling is very less.

In the same way, by keeping pace with its speed in the direction of the earth, the gravity pull is reduced by circling around it.

In such a situation, the risk of rocket or spacecraft falling on Earth is less.

Whereas if you send the rocket directly towards the space, then the gravitational power of Earth will pull you faster.

The earth rotates on its axis at a speed of about 1,600 kilometers per hour.

The rocket or spacecraft get the benefit of it.

It revolves around earth and changes its orbit again and again.

It takes time to change these classes.

Chandrayaan-3 first made 5 rounds of earth, then traveled in a long distance lunar transit orbit.

After this, Chandrayaan 3's orbit paths around the moon were changed.

This whole process takes a long time.

But the process of sending the spacecraft into deep space by rotating it around earth is less expensive.

This is the reason why ISRO's projects are much cheaper than NASA's.
