On The Space Show tonight, Dr. David Livingston intereviewed Dr. Bryan Laubscher. More on this in another post, but one of the topics that came up was a common question “What happens if the Space Elevator breaks?” The idea has been (un)popularized in Science Fiction (Ben Bova’s Mercury and Kim Stanley Robinson’s Mars trilogy come to mind) that such an event would lead to a planet-wide catastrophe. This is not true, of course, for the current vision of a Space Elevator – a ribbon to space, thinner than a sheet of paper. Depending on where the break occurs, much of it may fly off into space, much may burn up in the atmosphere and some may fall to earth.
Blaise Gassend (a name you should know if you are interested in any of the technical aspects of Space Elevators) did some serious study into this matter, going so far as to create some simulations. You can find them on this web page – they are most interesting.

Jan 18, 2007 Update – A reader posts a comment that Dr. Kalam, the person who made the address that I’m referring to, is actually the President of India, not just of this Science Center. I got confused – I thought that Manmohan Singh was the President of India, but I was wrong. He’s the Prime Minister of India. Dr. A.P.J. Abdul Kalam, indeed is the President of India. My sincerest apologies to Dr. Kalam and all those I may have misled.
To paraphrase Robert Heinlein (I don’t remember which novel this was in), “The laws of Physics work for everyone, not just Americans.” I’m sure I have the specific quote wrong, but I think I’m accurately capturing the sentiment he was expressing – if we don’t build it, someone else can (and will).
From Dr. Brad Edwards; “…here is a heads up on the Discovery Channel program to be premiering on Jan 28th. It is a very nice coverage of the elevator and is part of their 2057 series.”
First, the good news. It appears that a show which regularly airs on the Science Channel, Discoveries this Week, had a segment on Space Elevators and the recent Space Elevator Games. The bad news – there was no heads-up to this and all of us (with the exception of Brian Turner of the Kansas City Space Pirates) missed it. Brian says he cannot find this on the web at all, and, after some looking on my own, neither can I. But I have faith that someone will find it.

I received this email earlier today from Ben Shelef, CEO of The Spaceward Foundation.
Wirefly X Prize Cup was the partner for the 2006 Space Elevator Games. While no decision has yet been made as to whether or not this partnership will continue in 2007, it certainly is a strong possibility.
