As with so many things in science the translation to ordinary conversation 
can be deceptive. Low earth orbit is 'space' in the sense that it is a state 
of continuous free-fall, but it is not the hard vacuum of deep space. There 
is a thin plasma (the outermost layers of earth's atmosphere) at that 
altitude and it does have an effect on things. You can often see fabric, 
such as the jury-rigged 'heat shield' of the 1970s Skylab station, actually 
'flap' in the breeze up there. It is entirely possible that this plasma, 
which would have a lot of ozone in it, could interact with things up there 
and produce a distinctive odor. (Hmm, is ozone itself described as a 'burnt' 
odor?) Notice that the description is of noticing the odor on returning from 
a space walk. ("All of this is sensed once back inside") That makes perfect 
sense. The space suits have been exposed to the plasma for some period of 
time and some of it it would cling to them even after returning to 
pressurized atmosphere.

This I can agree with. Astronauts are a sort of 'celebrity' and need their 
privacy protected. It might be best to ask NASA to pass the survey to them 
and then return their answers. And most likely there are NASA engineers who 
could provide a better answer about what the astronauts are probably smelling.
