NASA-UAP-D7: Skylab Technical Crew Debriefing 1973

GI:E,SON are still on the windows. Just what that material is, I'm not

sure. But the remaining pieces should be useful for contamina-
tion studies.
CA:E:R One other item is the ammonia odor in the head which we dis-
covered about the last week in the mission. We weren't sure what
was causing it. Bill had changed out the charcoal canister.
We disconnected the boot between the charcoal canister and the
blower above it and took a sniff of that. We smelled, no ammonia
there. When we connected the boot back up to the blower, a
very strong ammonia odor came from the blower output. Thus it
appears that the source of the smell was the blower unit itself
and not the charcoal canister. As we said in our report of it
to the ground, we decided that it was tolerable for the rest of
the mission. Therefore, we didn't get into the mode of finding
another blower to put in there. I feel that the odor very
definitely increased in intensity during the final week of the
mission.
CA1R One other area of unusual events that we reported on the dump
tapes was that on occasion we saw some lights flashing outside
with very a definite motion relative to ours. We presumed that
they were other pieces of Skylab, or possibly other satellites.
We reported our two or three sightings of that kind as soon as
they occurred. We have no special comments concerning them,
