I love this sort of stuff Rob, Our PVR is full of stuff like Cox's programmes.
This Horizon programme was on a couple of evenings ago, it's been on before but it's still a great re-watch.
The remarkable story of how Hubble revealed the awe and wonder of our universe and how a team of daring astronauts risked their lives to keep it working.

Coxy also did a program a few years back where he talked about the Saturn VI rocket that took us to the moon and he revealed some amazing facts about the sheer power of the rocket engines, I can't find the actual episode but from memory it was something like:-
The most powerful machine ever constructed.
On take off it was generating enough energy to power the WHOLE OF THE UK.
The engines were drinking fuel at the rate of something like 14 tons per second.
In order to get this amount of fuel into the engines they had fuel pumps that had their own engines that were more powerful than a jumbo jet.
Absolutely amazing.
