The Camera That Changed the Universe

StartsWithABang writes As the Hubble Space Telescope gets set to celebrate the 25th anniversary of opening its eyes to the Universe, it's important to realize that the first four years of operations were kind of a disaster. It wasn't until they corrected the flawed primary mirror and installed an upgraded camera — the Wide Field Planetary Camera 2 (WFPC2) — that the Universe truly came into focus. From 1993 to 2009, this workhorse camera literally changed our view of the Universe, and we're pushing even past those limits today.

I recall reading about the mirror when it was being made, the precision with which it was polished was mind bogglingly accurate, if it was the size of Australia the largest deviation from perfectly smooth would be less than a millimetre. The problem was the shape (which changes slightly when put in zero-g), an extra shim in the framework that held the glass while it was cut was found to be the cause of the problem.

Cannot fathom why your post id marked redundant, OT maybe, but redundant?
