Why CHANDRAYAAN 2 following orbits.. not straight way to reach Moon? Straight Mission can save time and fuel ?
To get with straight way,one can save time to land at Lunar surface but it will be so costly BcZ it required large fuel consumption and much more thrust to pass out from gravity so more powerful aircraft engine needed which currently ISRO doesn't have, that's why ISRO use orbital path.
In orbital path, engine being started only when need to change the path of satellite and the rest time ,crayo engine (C-20) remain off & satellite moves only in orbit . This save much more energy and cost of the project and that is the reason #Chandrayaan-2 project cost much lower.
NASA's Apollo 11 mission was land at lunar surface just in 51 hr 49 minutes but its cost was 25 billion dollars in 1969.
Hope you will get that 👍

Going straight to moon will need a lot more fuel compared to reaching moon by gradually rising the orbit. When you go straight up, first you'll need a much stronger launch vehicle which india doesn't have. And it'll have to move against gravity completely on it's thrust. But by this method, GSLV can leave chandrayan on a LEO at it's respective orbital velocity, with out any fuel, it'll be able to orbit earth. And whenever it reches lowest point again, a few minutes of burning fuel can increase the size of the elliptical orbit, which in turn result in a higher and higher orbit. And When the orbit is high enough to have a low gravity, chandrayan can again burn it's thrusters and move in to the lunar transfer orbit.

Because this time we had a very heavy payload and again our rockets are not strong enough to send them in direct transfer orbit

1st of all ISRO don't have that much strong Rockets...2nd if we can go to the moon in using some natural Laws of solar systems and it's saving our money too.

It follows something called as Hoffman transfer. The vehicle follows an elliptical path. In an elliptical path,the total energy is conserved, and the energy transfer is only between potential n kinetic energy. So there is NO energy/fuel to be given as it follows an elliptical path. At the apogees and perigees, the fuel is burned which gives it a further push,which takes it to the next level, or a higher elleptical orbit. Thus,the spiral trajectory gives extra push it at certain ,designated positions to minimise energy consumption,and thus fuel consumption.
If it's a straight path,you have to give continuous energy/fuel to make it to the target.

Straight mission can save time but not fuel. And if we go in elliptical orbit we will not need big spacecraft to contain extra fuel which reduce the cost and it is easy to reduce acceleration in moon orbit

Having Rocket which can escape earth'd gravity on rise is not a problem. Real idea is maximising the output with minimum cost. Hence we go around to attain centrifugal force which is in turn helped by gravitational force partially to attain enough acceleration at Tangent where we need to exit earth's pull and proceed in targeted direction. This does takes some time but saves lot of cost. It really takes good amount innovation to do this kind job. Technically it is indeed a greener master piece as we end with limited exhaust.

Going elliptical will save feul and also increase velocity of spacecraft.. So they are going like that but going straight will need more energy because u need to escape from earth mag field and enter into the moon mag field u craft may have lot of chance to hit the moon surface hard... So they are going elliptical

Moving away from Earth's gravity at one go is not any easy task, hence taking sling shot at perigee for each orbit will put the satellite move away from Earth's gravity, and final ignition of thrust rocket will transfer the satellite into moons gravity field. The same technique is followed to any planet in our milkyway.

Isro chose a circuitous route to take advantage of the Earth's gravity, which will help slingshot the satellite towards the Moon. India does not have a rocket powerful enough to hurl Chandrayaan-2 on a direct path

In simple terms. To travel in straight line orbit, we need powerful rockets to escape Earth's gravity. Our current rockets do not have that much power.
