Monitoring of air flow in behind-panel areas allowed locating zones with insufficient air cooling
in the instrument area. It was proven that circulations of air flow in instrumentation behind-
panel areas affected topology of microorganism contamination of the ISS pressure hull.
Additionally, conditions of the pressure hull in the potentially hazardous zones were inspected
and the surface conditions recorded in a
database. Finally, a fungi database was
created to store images of the
microconditions of the test samples and to be
used in training ISS crew members to
preliminarily identify microorganisms and
assess growth of decomposer microorganisms
on the pressure hull surface.
