Space Interferometry Mission (SIM) cancellation [closed]

NASA's SIM mission was recently cancelled despite \$600 million being spent already over the last ten years. Has this \$600m been completely wasted or has any new technology been developed that could be useful in the future?

It doesn't matter how much has already been spent -- read any economy textbook for the concept of 'sunk cost'. The issue is 'opportunity cost' ... could we get better return by spending future money/man power/other limited resources somewhere else? –  Joe Jun 22 '11 at 0:41

I don't know about any new technology specifically from SIM, although it's entirely possible there was some.

However, the money definitely wasn't completely wasted, as it was used to employ probably hundreds if not thousands of people during that time that were working on various aspects of the project from design to prototype fabrication to simulations and studies of exactly what could be studied and observed, as well as project management, facilities personell, etc.

Disclaimer: I didn't work on the SIM project but I am a NASA contractor. And I did know some scientists involved with it.

An economist would probably argue the opposite - you took a large number of highly skilled people out of the work force. It's the 20th century equivalent of forcing farmers to build pyramids during the harvest instead of the rainy season! –  Martin Beckett Jun 24 '11 at 2:19
