Be aware that the History Channel show The Universe will air an episode at 2200 EST tonight (December 13) in which Richard Obousy will discuss interstellar propulsion concepts. The air time will probably vary depending on your cable provider, so be sure to check. Richard, once project leader of the Icarus effort and still actively involved at every stage of the Icarus design, is a Texas-based physicist whose work we have often discussed in these pages. I was there for his presentation on Icarus at the recent Oak Ridge interstellar workshop and look forward to seeing him on the tube.
Addendum: This episode is now available online.
