The body seems relatively cool compared to what I can find of the space shuttle, despite not quite knowing how long after touch-down the image was taken. I wonder if some new heat-dissipating technology, or similar, was amongst those being tested?

So it's just a few seconds after touchdown.
Picture is from a while ago.
