I guess you have a point but it's moot any way, they have already
struck it down. I still don't think it's a great idea to expend tens of
millions of dollars to destroy a piece of hardware that cost us
hundreds of millions of dollars to build. It was launched in 2006, so
it's only a couple of years old. Hardly obsolete at least in my
opinion. Why couldn't they have sent up a shuttle mission to repair it?
Or was the satelite obviously crap to begin with? It's a fortunate
thing we didn't implement this solution to the Hubble telescope when it
was malfunctioning.
