When MRO is breaking, does the pass through the Martian atmosphere "light up" visibly? What would it look like?

I hope MRO brakes and not breaks.

I doubt if it expends energy fast enough to glow -- except at infrared. Aerobraking is a long process.

During peak aerobraking, Zurek said, the atmospheric forces acting on the spacecraft will be roughly comparable to what one would feel sticking a hand out a car window at a speed of about 40 mph. But it is heat, not the aerodynamic forces, that pose the biggest concern. Engineers do not want MRO to experience anything higher than about 340 degrees Fahrenheit.
