Orbital spacecraft designed for partial reusability


The space shuttle is the most complex machine ever built and the first orbital spacecraft designed for partial reusability. It has a mass of 2,209,203 kg and is capable of taking up to 11 astronaunts and 24,400 kg of payload into orbit. For it to achieve orbit, it takes an average $450 million and a two stage rocket capable of delivering 5,253 kN of thrust. Once in orbit, it must maintain a speed of 17,500 mph. When the space mission is over, the shuttle must dissipate all of the energy in the form of heat (friction) by performing a series of S turns. Assuming the shuttle lands at 248.5 mph, has 7 astronaunts each with a weight of 200 kg, and a payload weight of 23107 kg, find how much energy (in GJ) the shuttle has the second that it lands (does not come to a complete stop).
