NASA Space Station On-Orbit Status 17 Jun 2003

All ISS systems continue to function nominally, except as noted previously
or below.

CDR Yuri Malenchenko and FE/SO Ed Lu continued cargo transfer operations
from Progress 11P, tracking the movements with the IMS (inventory
management system). [Some stowage location entries had to be corrected as
per uplinked radiogram from Moscow.]

As part of regular weekly maintenance tasks, Malenchenko inspected the
BRPK-1 air/liquid condensate separator of the SM’s SRVK water processing

Yuri also completed the daily routine maintenance of the SM’s SOZh
environment control & life support system, and prepared the daily IMS
“delta” file.

Ed Lu completed the periodic transfer of accumulated physical exercise
data files of the TVIS treadmill, RED resistive exerciser and CEVIS cycle
ergometer to the MEC (medical equipment computer), for subsequent downlink
to the ground. [The data file transfers involve PCMCIA (portable computer
memory card international adapter) cards from TVIS and CEVIS, plus the
entries from the RED exercise log book, individually for each crewmember.]

Both crewmembers performed their regular daily exercise regimen on TVIS,
CEVIS, RED and VELO bike with load trainer (for the CDR).

At 12:00 noon EDT, Ed Lu and Yuri Malenchenko, in colorful Hawaiian
shirts, participated in two interactive televised PAO interviews (Ku-band
& S-band) on KCRA-TV, Sacramento, CA, and CNN (Miles O’Brien), each one
lasting about ten minutes.

Immediately thereafter, the two crewmembers downlinked a televised message
to a graduate class of the Korolev Military Institute of Radio Electronics
in Zhitomir, Ukraine, via US assets. The occasion of the congratulatory
address was the cadets’ graduation from the nearly 100 years old Institute
and the conferral of their first commissioned rank. [“I would like to
express my sincere gratitude to the head of the Institute, Major General
Dmitri Vladimirovich Pyaskovsky, and to the professors and lecturers
responsible for the tremendously difficult task of bringing up generations
and generations of commissioned officers.” The Ukrainian city of Zhitomir
is also the birthplace of Sergei Korolev.]

After the installation of the electronic US-21 matching unit in the
Progress vehicle yesterday (6/16), which connects the Progress motion
control and DPO thrusters systems to the Service Module (SM) so that they
can be commanded by the SM computer system (BVS), Moscow today ran the
standard firing tests of the Progress approach and attitude control,
thrusters. [At 12:00 am EDT, station attitude was handed over from XPOP
to the Russian segment MCS (motion control system) for the tests,
conducted from the SM MCS via the US-21 matching unit. Thruster manifold
#1 (four jets) was tested first, at 1:36am, followed by manifold #2 (four
jets) at 3:12am. Afterwards, control authority was returned to the U.S.
CMGs for Momentum Management in XPOP.]

MCC-M/TsUP also performed the regular adjustment of onboard time via Regul
uplink, followed by onboard clock synchronization and daily state vector

Starting this morning at 12:30am EDT and ending at about 7:30am,
MCC-Houston and its support group in Moscow (HSG) performed a BCC (backup
control center) activation test, which did not involve the ISS crew. [BCC
utilizes the HSG command server and telemetry server. In test mode,
command function was transferred to HSG (as BCC) for sending a single PPCP
(preplanned command packet) to MCC-M/TsUP. TsUP activated ACT (American
contingency telemetry) via cyclogram for uplinking the PPCP to the ISS
with HSG confirming successful receipt. TsUP commanding to the Russian
segment (RS) via U.S. S-band as well as MCC-H-to-TsUP flow of status
telemetry were not affected, but MCC-H had no real-time telemetry and
command capability via Russian ground stations (RGS) during the periodic

The Science Officer was praised by POC (Payload Operations Center) on his
hard work yesterday performing the 30-day functionality test of the HRF
GASMAP (Human Research Facility/Gas Analyzer System for Metabolic Analysis
Physiology). [Good run time was obtained, and the check will be done
again in 30 days.]

SM battery #4 has been disconnected again. This leaves seven good 800A
storage units.

A conjunction (close encounter) with the SNOE satellite (Student Nitrous
Oxide Explorer, object #25233) occurred this morning at 8:33am EDT. The
object had been tracked for the last few days. Since its predicted radial
miss distance remained very stable at ~400m since Saturday morning (6/14),
no action was required.

The recent tests, on 6/7, to view ISS structure and components (in an
assessment of the optical inspection capability of ISS cameras for Shuttle
imaging) showed up some problems with camera zooming and focusing which
are currently under review and scrutiny by ground specialists.

After the ISS attitude transition on 6/12, the crew noticed a small,
shiny, free-floating metallic object about 30 m (100 ft) from the Lab
nadir window, moving very slowly away from the ISS. The leading theory was
that the object is a cable label. [A photo of a cable label, uplinked
from the ground, was later examined by Ed Lu. He confirmed the
possibility that the object he saw indeed could have been a cable
label. Further identification of the object by ground teams is still
underway. Limited tracking data the object on 6/12 showed it below the
ISS and 1.7 km in front. Preliminary predictions indicated it was slowly
separating, and the specialists did/do not believe it poses a re-contact
hazard to the station. Ed Lu’s image of the object can be seen

On 6/11, during Progress ingress activities, Malenchenko reported that the
air duct and fan assembly used to ventilate the cargo ship could not be
set up due to a missing connector. With MCC-M agreement, he installed
only the air duct, relying on an upstream fan to provide sufficient
ventilation. The connector was found later, but the fan could still not
be installed due to (temporarily) limited room. It was to be installed
after sufficient Progress unloading.

Today’s CEO (crew earth observation) targets, no longer limited in the
current LVLH attitude and including the targets of the Lewis & Clark
200-year memorial locations, were Lake Nasser, Toshka Lakes (the crew had
a good pass to look right of track for a mapping view of the record high
water levels in Lake Nasser and the Nile River), Eastern Mediterranean
Smog (on this descending pass in fading light towards the Middle East, the
crew was to look right of track over the eastern Med towards the Egyptian
coast and the Nile Delta. The ground is interested in views of sunlit
aerosol layers enhanced over the darker water), Western Mediterranean Dust
and Smog (as a cold front plows into the Iberian Peninsula from the west,
strong southerly winds over Algeria are expected to lift dust northward
over the western Med. As the ISS crossed northern Spain, the crew was to
start looking obliquely right of track for sunlit dust plumes), Wichita
River (the ISS approached this target with fair weather and good
illumination from the southwest. Looking just right of track to document
land use and stream patterns between the city of Wichita Falls and the Red
River), and The Dalles (LEWIS & CLARK SITE: As ISS passed over southern
Washington, the crew was to try to look right of track and map the lower
Columbia River. Of particular interest is the area known as The Dalles, a
great southward arch in the river before it cuts through the Cascade Range).
