All ISS systems continue to function nominally, except as noted previou
sly.  Week 7 of Expedition 5 is underway.

CDR Valery Korzun and FE-2 Sergei Treschev conducted an IMS (inventory mana
gement system) audit to update the system on Russian segment (RS) equipment

FE-1 Peggy Whitson meanwhile monitored the powering up of the HRF GASMAP (h
uman research facility / gas analyzer system for metabolic analysis physiolo
gy) byh MCC-H and later performed the 90 Day Health Check. [GASMAP, house
d in the HRF rack, is used for periodic assessment of crew aerobic capacity
by analyzing human metabolics, cardiac output, lung diffusing capacity and v
olume, pulmonary function and nitrogen washout.  It employs two pieces
of hardware, the Analyzer Module (AM) and the Calibration Module (CM). The f
irst contains sensor and electronic hardware to measure and analyze the inha
led and exhaled breath stream of crewmembers. The CM supplies high-pressure
calibration gases to the AM.  Calibration gases, housed in three cylind
ers, are specific mixtures of oxygen, nitrogen, carbon dioxide, argon, heliu
m, acetylene, hexafluoride, and carbon monoxide.  When in use, crewmemb
ers have their own individual mouthpiece and saliva filter, which are replac
ed every 90 days.  GASMAP is activated for brief health checks every 30
days to maintain high internal vacuum, i.e., to ensure the unit remains emp
ty and uncontaminated. Today’s full functional health check by Whitson, whic
h included a routine check of the AM’s internal vacuum as well as a calibrat
ion check, is conducted every 90 days. The procedure was broken into two par
ts, separated by a minimum of 5 hrs to allow for adequate hardware warm-up.]

Korzun and Treschev replaced a remote control unit for the DC-1 airlock sys

Later, the two cosmonauts also removed the failed 800A battery #6 in the FG
B and replaced it with a new unit.  The old battery was stowed for subs
equent deorbit, and the change was recorded in the IMS.

CDR Korzun installed the PUMA optical collimator sighting device at a Servi
ce Module (SM) window in preparation for upcoming tasks.

In the Lab, Peggy Whitson reconfigured the valves to allow for activation o
f the second CCAA (common cabin air assembly) set and dry-out of the first s
et..  This “swap-over” between the two CCAAs is done by the crew once a
month to dry out the heat exchanger of the deactivated side..

FE-2 Treschev completed the daily routine tasks of SOSh life support system
maintenance and IMS delta file preparation, while Whitson conducted the dai
ly Lab payload status checks.

Whitson also performed the weekly/monthly maintenance of the TVIS treadmill
and the weekly maintenance of the CEVIS (cycle ergometer with vibration iso
lation system).

All crewmember completed their daily physical exercise regimen.

The crew received grateful kudos from MCC-H/PAO for the educational "T
oys in Space" program, conducted with great success on 7/16 (Tuesday).
 "Both clients (Houston and New York City) were tremendously pl
eased with the outcome of the interviews, and all the students were amazed a
t what you were able to display for them up there.  Jump ropes will nev
er be the same for them after they’ve seen what you can do from up in space!
 CNN videographers were at the American Museum of Natural Hi
story in New York and videotaped the kids’ questions and reactions to the cr
ew’s toy demonstrations. Their museum footage, along with the event, was use
d by CNN in a feature that ran repeatedly the entire day of July 18.

Coming up for the crew week are four PAO events, two within one comm. windo
w on 7/24, and the remaining two within one comm. window on 7/25.  All
of this week’s events will involve Peggy Whitson only.  The first event
on 7/24 will be a downlink to Marshall Space Flight Center (MSFC) in Huntsv
ille to announce a spectacular ISS sighting opportunity during an overflight
over Huntsville, Alabama on 7/26. The event on 7/26 is hosted by the Nation
al Space Science and Technology Center (NSSTC) with a "Space Station Bl
ock Party" (from 9:00 – 10:30 pm EDT) for families, students, and commu
nity leaders.  The other events are audio/video Q&A interchanges wi
th the Orange County Register, KCRG-TV in Cedar Rapids, IA and the Creston,
Iowa Daily News.
