Why don't spacecraft burst into flames? (Thermodynamics Question)

In a thermodynamics class, I learned about enthalpy and how it is a measure of the total energy of the system. It also allows us to measure a quantity known as specific heat, where specific heat refers to the amount of energy required to raise 1kg of a material 1 deg C.

Here's where I'm confused:

If you do work on a system, you are adding energy to that system. So in order to get a satellite into geosynchronous orbit, an equivalent amount of work must be done in order to increase the satellites kinetic energy (bringing it up to orbital velocity) and its potential energy (bringing it up to orbital altitude). These two energies combined, should amount to many, many kiloJoules of work and energy transferred to the satellite. 

Let's take a 2000 kg satellite made entirely of aluminum at geosynchronous orbit as an example:

m = 2000kg
distance from earth (r) = 42156 km (from wolframalpha.com)
orbital speed (v) = 11067 km/hr (from wolframalpha.com)
Sp. Heat of Aluminum: 0.902 J/(g*C)

The satellites PE (mgh) = 826260000 kJ
satellite KE (1/2mv^2 ) = 9450500 kJ
Sp. heat for 2000 kg Al: 1804 kJ/C

Which means it requires 1804 kJ of energy to raise the entire mass of satellite 1 degree Celsius. OK...KE+PE = 835710500 kJ...

which means at geosynchronous orbit, the satellite should be at a scorching 463,250 degrees C greater than its temperature at 0 m/s on the surface of the Earth.

Obviously satellites don't burst into flames/melt during ascent, so what am I doing wrong here?

The Energy is being converted into Kinetic Energy rather than Thermal Energy.

Instead of all of the particles being given random motion by the energy, they are all accelerated in the same direction so relative to the spacecraft, the particles are all moving randomly in roughly the same way as they were before.
