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.

It was the press coverage that was the disaster

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.

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

Discovery

The Hubble Space Telescope made us realize that space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.

One of many

It is a little sad that while at least seventeen of these giant telescopes have been launched by the US alone, only one has ever looked up.

NASA does not have the funds to build instruments, or to run them once they have been launched. One of the telescopes is being used for the WFIRST mission (http://wfirst.gsfc.nasa.gov/science/). The other is waiting for money.

This is ridiculous....

I get the quantum mechanics principle, the mere act of observing changes the observed, that you can't measure the momentum or the position without affecting the other. But, just put a telescope in the orbit and it changed the universe? ... come on guys, there should be some limits even on hyperbole.

I change the universe all the time. Of course, most of it will never be affected by those changes, but changes they are.

Great book of the story behind the repair mission

[SuperKendall]

A photographer was given broad access across all of NASA years before the mission launched to fix the Hubble, and he put together an book of amazing photos and stories behind the mission:

Infinie Worlds by Michael Soluri. They have a hardcover and a Kindle version, not sure how the pictures would come out in the Kindle version but the hardcover is pretty large and the photos look great.
