A 6.5 metre mirror would be one heck of a capable telescope down on earth even by today's standards, but above the atmosphere, I'm sure it is going to make some fantastic discoveries :)

Amazing project; no pressure on those guys given where it's going (with no possibility of being able to fix it if it goes wrong). Giver that it's budget has spiralled from $1.5 billion to $8 billion, I was surprised that this is still less than Hubble cost if you factor in all the servicing visits. Found this useful mirror comparison chart, I'd never heard of the "Overwhelmingly Large Telescope" project (love those inventive names :rolleyes: )
