The Camera That Changed the Universe

Posted by samzenpus on from the all-the-better-to-see-it-with dept.

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.

    Despite the slight change in the curvature of the main mirror, Hubble's images were pretty amazing. It was the press and the politicians that called it a disaster. Fortunately, that didn't prevent NASA from sending a crew to install corrective optics and a better camera.

      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.

      Despite the slight change in the curvature of the main mirror, Hubble's images were pretty amazing

      Amazing maybe, but far below what was promised. There isn't any way to gloss over the fact that the project managed to screw up the single most important component in the telescope. The mirror ended flawed and in orbit not because it was too technically challenging, but because of arrogance, sloppiness, and poor oversight. The taxpayers have a right - even today - to be pretty steamed about it.

      Imagine if someone sold you a sportscar, promising it would handle like a dream and hit 200 mph on the straightaway. When you finally receive it and test it out, it shimmies like a banshee and can only manage 100 mph. When you call to complain about it, you find out that during construction, the technicians got drunk one night, ground the cam shaft wrong, and left out one piston. The company sold it to you anyway, not because they were trying to cover anything up, but that they simply didn't know anything was wrong, because they'd never bothered to test drive it before shipping it. Your argument is that we should still have been happy to have it because it's better than the Honda Civic we were used to driving. And, given the etymology of the word , "disaster" is a good choice.

    The camera only changed the universe if we are in a simulation with lazy evaluation (things are extrapolated and created to be as they should exist when we look at them) or or if something like quantum superposition applies on a macro-level (the observed matter's state is changed based on our observation of it).

    The camera didn't change the universe, it changed the *known* universe--made us a little less ignorant. For millenia mankind expanded its knowledge of places by travelling to them. That has now become prohibitive for almost every place in the known universe.

    The easiest stuff is done. We still need to explore the oceans and the solar system, where travel is quite inefficient but not utterly prohibitive.

    We also need to develop defense against world-killers. Biological, nuclear, and simple kinetic energy.

    And the big hump after that should be interstellar exploration. Multigenerational, multicentury.

    We'll need to figure out relatively stable world government and economy before that happens, so give us another four to twelve centuries, I'd say.
