NASA Space Station On-Orbit Status 11 June 2003

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

Progress 11P linked up with the station smoothly and two minutes ahead of schedule (7:15am EDT).  The cargo ship, carrying about 5300 lbs (2400 kg) of consumables, clothing, spare parts and propellants, is now docked at the DC-1 “Pirs” docking module, radially to the ISS longitudinal axis.

Progress Background: The unmanned Progress is similar to the manned Soyuz spacecraft, but has a cargo module (GrO) instead of the Soyuz Orbital Module and a refueling module containing propellant tanks instead of the Descent Module.  The Progress can transfer propellants into the ISS (SM & FGB) through fluid connectors in the docking ring, and the propellants in the refueling module can also be used by the Progress thrusters for controlling and reboosting the ISS.  Propellants can also be transferred back into the Progress.  The older Progress M’s refueling module has four propellant tanks (two each for fuel & oxidizer, totaling 845 kg of props), and two water tanks (420 kg).  The newer Progress M1 “tanker” has eight prop tanks (1695 kg) and no water tanks in the refueling module, but separate water containers in the cargo module.  Total payload capacity for both Progress versions is 2500-2600 kg.  The current 11P ship is the newer M1 version (M1-10, or #259); it differs from previous M1’s in that it has been fitted with a Rodnik water tank in its cargo module.

CDR Yuri Malenchenko, having stood by on the “hot” TORU control station in the Service Module (SM) in case of failure of the automated Kurs system, returned the station to nominal stage operations communications configuration and deactivated the video connection to the Ku-band assets in the U.S. segment (USOS).

At about 7:40am, Malenchenko and FE/SO Ed Lu performed the mandatory 1-hr leak check of the Progress-DC1 interface.  The two hatches between the DC-1 and Progress were then opened at about 8:40am and the quick-release threaded clamps installed by Yuri and Ed.

Malenchenko performed the scheduled Progress air sampling with the Russian AK-1M sampler, then deactivated the Progress systems and installed the air vent ducting from the SM and DC-1 for ventilation of the M1-10’s cargo compartment.
In the cargo module, the CDR then installed the LKT local temperature sensor commutator (TA251M1B) of the BITS onboard telemetry system and its ROM (read-only memory) unit (TA765B).

Ed Lu meanwhile disconnected the UOP-DCP (utility outlet panel to display & control panel) power cable for the RWS (robotic workstation) which had covered the docking with its video system.

Before the docking, a radio-equipped accelerometer (RSU/remote sensing unit) of the IWIS (internal wireless instrumentation system) was installed in the SM for structural dynamics measurements.  After the docking, Yuri removed the RSU again, while Ed transferred the recorded structural dynamics (vibratory) data to computer storage.

First priority of the Progress arrival was changeout/update of onboard crew procedures books with new pages delivered by 11P.  [ISS crew procedures deal with generic Progress transfer ops (RPR), EVA cue cards, technical experiments, SOZh life support, IFMs (in-flight maintenances), etc.  Soyuz crew procedures include ops for ascent and descent, backup modes, orbital flight, off-nominal situations, etc.]

The Science Officer completed the daily routine maintenance of the SM’s SOZh environment control & life support system, did the regular status checkup of autonomous Lab payloads, and prepared the daily IMS inventory “delta” file.  [MCC-M wanted to make sure that before downlinking today’s delta file, the crew included an update on used EDB water containers, KTO solid waste containers, KBO-M soft waste bags, and KPL food ration containers,- all information needed to account for resources and develop resupply manifests.]

MCC-H asked Ed Lu for further description of the damaged TVIS treadmill harness shoulder straps and his work-around fix of the broken buckle.

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 Amman, Jordan (the Jordanian capital was located just left of track NE of the Dead Sea), Athens, Greece (the historic Greek capital lies on the coast, just to the right of track), Istanbul, Turkey (the Turkish capital lied just right of track and straddles the narrow Bosporus channel between the Sea of Marmara and the Black Sea), Brasilia, Brazil (nadir pass over this master-planned capital city in the Brazilian Highlands), Casablanca, Morocco (there may have been some coastal clouds, but otherwise the crew had a nadir pass over this port city of motion picture fame), Barcelona, Spain (this large city on the Spanish Riviera lied just left of track), High Central Andean Glaciers (with a break in the clouds the crew may just have been able to spot and document these small, illusive targets. Using the long lenses for detail), Karachi, Pakistan (CITY AT NIGHT: Looking for the lights of this coastal city, just left of track), Bombay, India (CITY AT NIGHT: This mega city crowds a small peninsula to the left of track), Tel Aviv, Israel (CITY AT NIGHT: The Israeli capital is on the coast, at nadir and should have been the brightest feature), and Amman, Jordan (CITY AT NIGHT, on this second pass: The lights of the Jordanian capital should have looked isolated in the desert and near nadir).
