Training Project: Bob and Blobs

You live on the planet Bob. Bob (Bob has a radius of 8432 Km and a mass of 6.822 × 10^26 kg). The industrial revolution on Bob has transpired differently than on Earth due to mainly the ability to construct springs of extremely large spring constants. The space program of the planet Bob is reliant on springs to send objects into orbit and for propulsion. However, the scientific community has recently moved to experiment with new forms of energy such as nuclear power. One of these experiments has been the sending of a nuclear-powered satellite (mass of 6900 kg) into orbit around Bob at a distance of 22,600 Km. However, issues have arisen with the coolant system of the satellite and it is in danger of exploding and releasing harmful radiation into the upper atmosphere of Bob. You must set the satellite on a path outside of the gravitational pull of Bob in order to save the day. To do so, you have the ability to fire large blobs of a putty-like substance from the surface of Bob. The biggest blob you have access to is of mass 5000kg. What spring constant do you need to fire a blob to hit the satellite and send beyond the gravitational pull of Bob.
