Not really a policy question, but I hope you'll forgive the occasional
not-quite-on-topic thread...

Does anyone know what sort of TPS (thermal protection system) SpaceDev
is planning to use on its Dream Chaser orbiter? It all sounds like a
reasonable design to me so far, but reentry is probably the hardest part
for a reusable lifting body, and I'm curious what their approach to that
might be.

Thanks,
