POCC STATUS #6
SLS-1
POCC STATUS REPORT #6
JUNE 10, 1991
The crewmembers aboard the orbiter Columbia began their sixth
day in space with a full schedule of activities that
includes the continuation of the baroreflex testing, and the
cardiovascular studies related to rest and exercise at 30%,
60%, 90%, and 100% levels of maximum exercise capacity. Leg
volume measurements will be made along with leg compliance
and blood flow determinations. In addition, echocardiographic
imaging of the heart will take place to further investigate
the changes in volume and other structural characteristics of
the heart due to microgravity and how these changes are
related to changes in cardiovascular function.
An activity that has been carried out on a previous Spacelab
mission is a neurosciences study looking at how the
crewmembers perceive motion and orientation in space. The
investigation, which is planned for today, uses a rotating
dome that rotates around the crewmember's visual field to
create a specific sensation and to measure the crewmember's
perception of that sensation. Today's activities also include
the routine rat health check and the videotaping of the
jellyfish behavior.
The crew has been extremely busy during everyday of the
mission so far. Each day, they have begun their science
activities early and at times have even worked through their
meal times. This has resulted in a dramatic increase in the
amount of science that has been accomplished.
