Impressive work shown live on NASA TV; and I wonder...

All those items, assemblies, tools they are handling, replacing, touching... at what temperature are they ??

i remember at one point, i think on the first EVA that the astronaut commented that the handrails on the hubble being cold even through the insulated gloves of the space suit. so pretty damn cold i'd imagine.

 

the insides especially as many of the instruments need to be cold to avoid interference from hubbles thermal radiation.
