Musk has stated that the BFS will need a heat shield capable of reentering the atmosphere from interplanetary trajectories. So I take it the ship will come in directly from the transfer trajectory and rely on arobraking to slow down to land.

Main part of question: what will the heat shield be made of?

Bonus: What speed would a return from mars have? Thoughts on the heat it would produce in contrast to earth orbital return.
