A spacecraft with a mass of 4500 kg is in a circular orbit 200 km above Jupiter's surface. The spacecraft must use its thrusters to transition to a higher circular orbit, 600 km above the surface. Given that Jupiter has a radius of 69,911 km and a mass of 1.89 × 10²⁷ kg, calculate the amount of work required for the thrusters to move the spacecraft from its initial orbit to the higher orbit.
