Every 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.

To <7 degrees!

> … down to its final operating temperature of less than 7 kelvins

I 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…)
