James Webb Space Telescope
bknight:
In the recent thread with Neil Baker concerning the PLSS, one link to the massive NASA vacuum Chamber A leads me to a question.
http://www.nasa.gov/centers/johnson/engineering/integrated_environments/altitude_environmental/chamber_A/
In the link NASA is in the process of a reconstruction project to allow the James Webb Space Telescope to be tested in the chamber. I wonder whether NASA learned from a huge past mistake in the Hubble Space Telescope to checking every detail so this won't be another black eye for them?
We won't have a way of going to the telescope with people at least to fix a mistake. Perhaps robots could be programmed to do repairs.

What black eye, are you referring to the problem with the correction to Hubble's mirror?
bknight:
Yes, sir.

Well, unless others here want to correct me, a vacuum test would not have picked up that error. The error in the mirror was due to a contractor rushing a step in the calibration of an interferometer.

Actually I wasn't thinking about a vacuum chamber test, the article said they were remodeling it to accommodate the telescope. I was rather hoping the guys in charge would check out all the mirrors and alignments so we don't have a repeat of Hubble.
I guess I didn't have enough coffee when I penned that this morning.
