Question: is it hot inside a spacesuit?

hi lozza well i wouldn’t know from personal experience – sorry my photo is a lie!!
I think it probably does though, partly due to suns radiation heating the spacesuit up (this is why spacesuits are white – to reflect as much solar radition as possible), but also due to the astronaut producing a lot of heat!! Astronauts have known to have had difficulties in their spacesuits from the heat. The surrounding space is such a good thermal insulator it is very difficult to get the heat away. There have been times when spacewalks have been cut short due to the astronaut overheating! In one case the spacesuits visor completely steamed up and he couldn’t see a thing!
