Comments on: Rocket science, in the bag http://blogs.discovermagazine.com/badastronomy/2006/07/21/rocket-science-in-the-bag/ I am an astronomer, writer, and skeptic. I likes reality the way it is, and I aims to keep it that way. My real name is Phil Plait, and I run the Bad Astronomy blog.

Maybe I can be of help to the Falcon Rocket people. Or not. Ivan. Oh, and Irishman, (I guess you will read this sooner or later), I’m still developing that nut/bolt thread idea.

FWIW, I did a quick web search on "B nut" and found this site: http://www.fas.org/spp/military/docops/smc/bnuts18.htm So if this were an Air Force LV, they wouldn't be allowed to use B-nuts. Maybe this lesson was learned before, by someone else?

Sorry about the spelling of aluminium, but I think it looks better in Europese :-) Ah, they probably forgot why they chose aluminium first place and when the next rocket blows up they suddenly remember some obscure little detail.

It might be quite a bit. I wonder what the weight penalty will be for switching to steel? It might be quite a bit.

Since they were anodized, but corroded anyway, a handling issue was probably involved as well. The aluminum nuts were probably used for mass savings.

And they will be changing over to all stainless steel on their next attempt. BB, they claim that the stainless steel nuts are much cheaper than the aluminum ones.

I really wish journalists would Google the clauses and phrases they want to use in article headlines ("busted nut" ~ "bust a nut"...). I could easily submit this to Collegehumor.com to put up as a daily hotlink for "hilarious headline," for the n-thousandth time. “Falcon 1 Failure Traced to a Busted Nut”??
