Update: Since I first saw this a lot more info has emerged. Here are some factoids from the Cosmic Log:
- NASA has had them is storage since last year, at a cost of between $75k and $100k/yr.
- The assemblies will shave ~$250M off a billion dollar budget, so using them isn't cheap..
- Thus, NASA is kicking around using just one of them due to budget issues with a 2024 target.
- It won't replace the James Webb Space Telescope but could be synergisticly. It could replace (or become?) the proposed the proposed Wide-Field Infrared Survey Telescope (WFIRST).
- Overall, it is shorter than the HST, so it is being called 'Stubby Hubble.' Since it would be more powerful, it is also 'Super-Hubble.'
