Projects that push aside the envelope of what was previously possible and reach entirely new levels of performance tend to have not that predictable schedules and costs. I'm pretty sure the planners involved know that, but on the political level fixed ranges and estimates are required to get funding - so you get cost overruns and delays.

- lisper 5y agoAnd the fact that everyone knows this leads to some interesting game theory.
- perardi 5y agoEvery HN thread brings up the cost overruns, and I just…OK, smart guy, you come up with a reasonable estimate of shooting a telescope into a very distant orbit and then cooling it to 12 degrees above absolute zero.

- Sharlin 5y agoI guess the GP means US customary degrees rather than standard ones (also technically kelvins are not "degrees", the unit is simply K rather than °K, but as they share the magnitude with °C the difference gets muddled when talking about relative temperatures…)
