Re: The first rule of government spending
Ironically a copy could cost much more.
This thing was built by a bunch of defense contractors over a decade, in plants that may have been shut down, by people who have left/retired, with components that are no longer made, with subcontractors that have gone out of business/been sold.
If you want to make an equivalent telescope, it's not too hard. If you want to make a precise copy, where you use this particular memory module from 1999 because it passed radiation tests and this type of kapton tape from this supplier is good for 10 years in vacuum - then it gets really hard.
It's why military aircraft projects tend to be very expensive, you build an order of x000 airframes and all the spares they are going to need for 30-40 years, because starting up a line to make a replacement PCB for 1980s fighter is $$$$$$
One colleague of mine was trying to get samples some particular astronomical emulsion - which Kodak stopped making because it contained Buffalo gelatin which was banned by BSE regulations. The Keck telescope, built in the 90s, has an entire team building replacements for 80/90s era control hardware.
