Abstract

Six crew members on ISS sometimes need to spend much their time to fix
core system problem such as exercise equipment, water processing system,
and Toilet system. This bears upon the time to perform Space Science
experiments and/or ISS system operations.

Furthermore it increases that stowage volume for on-orbit spare parts
for these core systems.

Deficiency of the stowage volume makes crew uncomfortable to live there.
 It also makes difficult situation of finding stowage items.  The best
way to reduce the volume of on-orbit spare is to improve reliability of
core system equipments.  However this needs a lot of system improvement
and takes cost and time.  We have several things to do in addition to
improve core system reliability to less crew time to find items easily.
 JAXA is now studying how we can improve Flight Controllers supports to
find things crew needs from the ground.

In this manuscript, JAXA introduces two effective approaches to minimize
crew time for finding items and to reduce the stowage volume. At first
we review current ISS system operations which tasks to impact crew task
for accomplishing science experiment and scheduled system tasks.  After
that, systematic approach is discussed how Flight Controllers on the
ground can support crew member to find things.

At the last, we will show the new Replacement and Recovery concept for
JAXA new improved Ethernet hub which intend to improve the stowage
utilization.
