With the launch of the Shuttle Mission to repair the Hubble Space Telescope. I think it is time to define its worth..
Hubble was designed with maintainability in mind. With this approach it cost ~ 10 Billion dollars to maintain over its life time.

Now when you determine what a project is worth you also have to determine what benefit it had has with future projects for NASA.
In other words human's in space repair an instrument is photo op a benefit when going to congress for more dough.

But how many Chandra's without maintainability in mind could you have launched for 10 Billion

Hmmmm...

Well firstly, it's not my taxes ... :-)

HST is a civilian version of KeyHole, and the boner with the optics was management not scientific. Yes, in place testing IS a good thing but pre-launch is BETTER. By some $Billions I expect. This I think has haunted the project.

There has been repayment on some unique scores : deep field surprises, solar system object imaging ( Pluto/Charon ), practice for astronauts.

The faster/cheaper/better approach sort of fell over the get-what-you-pay-for hurdle ( foot-pounds for Newtons anyone? ). Mind you the Shuttle suffered early on and thus wound up an all purpose committee camel.

There is no doubt that human time in space is a horrendous cost compared with human-free. That's a bankable guideline for sure, and far less tragic. If humans don't need to go there, then don't take them ....

Maybe we should combine the invaluable US experience with the Russian keep-it-simple-and-keep-it-brute-force methodology.

My 0 cents worth.

Cheers, Mike.
