The Cassini spacecraft was a mission to Saturn which observed Saturn and several of Saturn's moons.Assume Cassini is in a circular orbit around Saturn. NASA wants to enlarge Cassini's orbit so that it will pass by one of Saturn's moons that is on an orbit farther away from Saturn. To do this, they will need to fire the thrusters...0 0 0 0 0 0on the back, speeding it up to faster than escape velocity.

Step 1

As cassini spacecraft is moving in the circular orbit and we want to make it move in enlarge orbit here

so, to increase the orbit we need to increase the velocity of the spacecraft & to decrease vice versa.
Also, the thruster for this purpose is provided on the back of space craft.
The need of increase in the velocity will be higher than the circular velocity the rate at which it is currently moving.
The new orbit will be the elliptical one.
