I don't wish to sound sound dismissive, but I'm really not happy about anyone coming along claiming something as remarkable as a nuclear holocaust on Mars and apparently not engaging with serious journal articles that would (if true) discredit his hypothesis. Is anyone who owns a copy of the book able to tell me whether Dr. Brandenburg addresses the Musselwhite et. al. articles in that publication? If not, that would be really bad.
It's also worth pointing out that his other claims about trinitite being found on Mars are also, apparently, not supported in the literature; and noteworthy that he didn't refer to this apparently discredited claim in the interview. Maybe he has something to say about this in the book, I don't know.
Also, the idea that a supposedly "bronze age" civilization could, or would, have built structures of that immense size on Mars seems wholly preposterous. Nothing remotely similar exists on Earth (compare the size of the Cydonia "face" to, e.g., Silbury Hill). But that is not entirely essential to his hypothesis, so I'll leave that to one side.
This is even before we get onto areas such as his claim to being secretly supported by government agencies who daren't fund this research publicly. This seems, to me, like a clever line that will be picked up by others in the field because it's so flattering to those making the claim, and because it ties in with what some people want to believe about the omniscience of secret military structures. All the more convincing, because there may be a grain of truth in it, to the extent that some people working for government in this general area are (presumably) interested in this stuff too. But ultimately it doesn't make a blind bit of difference to the evidence that Dr. Brandenburg is presenting, which seems weak at best.
Skeptiko is extremely useful and good in that it provides a forum for those with supposedly "wacky" theories to air their views without the kind of groupthink that exists around controversial areas of science; however, in this case I think the interviewee should have received a lot more pushback than he did. The interviewer was so gushing that at times I was concerned for his underpants.
