This Week at NASA reports that the Mythbusters are recording an episode about the "Moon hoax" — you know, the claim by conspiracy nuts that the Moon landings of the late 60s and early 70s were faked. The show has recorded segments at several NASA centres, but I have no idea about when it's going to air (neither in the US nor in Australia, especially with SBS's wild rearranging of the order of the episodes...).
I wonder if Phil Plait, the Bad Astronomer, is involved with this. He has an excellent website responding to the claims of the "Moon landing deniers", and apparently he was approached by the Mythbusters years ago with the possibility of doing some astronomy-related segments...
I'm not at liberty to say.
