Infrared view in google sky ? what do you think?

    I read somewhere that a Sattelite can not stay in a fixed spot relative to the Earth and that there course has them looping back and forth across the equatorial plane.  I was always amazed at the amount of heat experienced by a spaceship returning to Earth.  I always thought that if they took the energy that was coming on board the craft and used it to slow down the rentry velocity it would be alot easier on everything involved.  Instead of insulation and tiles some kind of heat to propulsion conversion.  The fall to earth would be more of an oscillation than a straightway burn out.  You figure they use umpteen amounts of fuel to go up converting that into a huge amount of inertia in a small amount of mass.  Then waste all that inertia getting back down.  Then again I'm still waiting for dynamic brakes to charge the battery in my moving oil burner with wheels and some pyroelectric converter to replace the radiator and a piezoelectric converter to replace the muffler and some magnetic bearings that do useful work instead of just heating up.  We are traversing the spacetime continoum at millions of miles an hour if we could only figure out how to convert this inertia into inertia in a more desirable vector we wouldnt need an engine at all. Just a dynamic braking system.
