Why Hubble Broke and How It Was Fixed 73
angry tapir writes "I recently had the opportunity to sit down with Charles (Charlie) Pellerin, who was NASA's director of astrophysics when the Hubble Space Telescope launched with its seemingly fatally flawed optical system. Pellerin went on to head up the servicing mission that finally fixed the telescope and for that was awarded NASA's highest honor, a Distinguished Service Medal. Since Hubble he has done a lot of thinking about the problems that led up to the error and how organizations can best avoid making similar mistakes."

I worked at Ball Aerospace years ago and found out the real story. NASA cut the budget for Hubble so that a final optical train alignment task was never done. The engineers had designed a laser test to check the optical path but NASA wanted to save the $50000 the test would take. So until it was turned on, in space, they had no clue how bad it was. Working with NASA was tough mostly due to their arrogance.

I wanted to joke about the PhDs getting drunk at their desks, but there are a couple of gems in the text:
We see this very clearly when discussing evoting.
Then towards the end there is an interesting analogy of the Shuttle accidents with a Korean airline company having an extreme crash rate, referring to people put under too much pressure, and irrational .
It's actually a good read for people interested in managing.

NASA specified SI.
Supplier did not supply SI, since it bases its measurements on US system.
Problems.
Yes, it was a communication and management error, but not entirely. It has been standard in scientific settings to use SI units for years and years. Failure to use them *especially when specifically outlined by the design brief* is not just a "communications problem" - it's a fundamental error in the product that was delivered unfit for purpose.
