NASA Space Station On-Orbit Status 15 July 2005
SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by SpaceRef.com (copyright © 2005) to enhance access to related status reports and NASA activities.
All ISS systems continue to function nominally, except those noted previously or below. As investigation of the STS-114 ET/ECO sensor anomaly is continuing, with no new launch date set yet, the crew today had a rest day.

As a checkout toward the proposed Soyuz-216/10S relocation on 7/19, the CDR supported the standard ground-commanded hot firing test of the spacecraft’s SUD motion control system, first pressurizing the String 1 section of the combined propulsion system propellant tanks & pressurization tanks (KDU), then conducting, at 6:50-7:10am EDT, the standard 1-minute hot fire test with the thrusters. [KDU comprises both maneuver and attitude control engines of the Soyuz. For the test, station attitude was handed over to Russian thruster control at 6:40am, commanded to free drift, and after the test back to LVLH XVV. Attitude control returned to USOS momentum management at 7:25am. During the test firing, Krikalev remained in the Soyuz Descent Module (SA), with its gas analyzer activated for safety. Preliminary results of the test indicate a nominal thruster firing; however, communication problems developed on VHF2 during the test. On a later orbit, an additional communications test was completed and all was nominal.]
Overnight MCC-H powered up the SSRMS (Space Station Remote Manipulator System) and pointed the tip and base elbow cameras away from the Soyuz. [Engineering analysis had indicated that the contamination from the hot fire test and the relocation were above the “budget” allocated for the cameras. As a result, the cameras were pointed towards the SSRMS booms to protect them.]
The FE/SO completed the regular weekly maintenance reboot on the operational PCS (Portable Computer System) laptops and the bi-monthly restart of the OCA comm router SSC (Station Support Computer) laptop.

John Phillips also filled out the regular weekly FFQ (food frequency questionnaire), his eleventh, which keeps a log of his nutritional intake over time on special MEC (medical equipment computer) software. [On the MEC, John is using his personalized file that reflects the food flown for his Increment. The FFQ records amounts consumed during the past week of such food items as beverages, cereals, grains, eggs, breads, snacks, sweets, fruit, beans, soup, vegetables, dairy, fish, meat, chicken, sauces & spreads, and vitamins. IBMP (Institute of Biomedical Problems)-recommended average daily caloric value of the crew’s food intake is 2200-2300 cal. If larger quantities of juices and fruits are taken into account, the value can go to 2400-2500 cal.]
Sergei Krikalev did the daily routine maintenance of the SM’s environment control & life support system (SOZh), including its toilet system (ASU).
John collected the periodic reading of the cabin air’s current CO2 partial pressure in the SM and Lab, using the U.S. CDMK (carbon dioxide monitoring kit, #1013), for calldown, along with the battery status, for use in trending analyses.
The FE had another 45 min. for hardware/cargo prepacking for return on the Shuttle. [The ground uplinked some last-minute manifest changes on LF-1 that modified John’s Prepack List.]
Both crewmembers conducted their regular 2.5-hr. physical exercise program on the TVIS treadmill, RED resistive machine and VELO bike with bungee cord load trainer. [Sergei’s daily protocol prescribes a strict four-day microcycle exercise with 1.5 hr on the treadmill and one hour on VELO plus load trainer (today: Day 2 of a new set).]
Afterwards, John transferred the exercise data files to the MEC (Medical Equipment Computer) for downlink, as well as the daily wristband HRM (heart rate monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).
Working off his voluntary “time available” task list, Sergei conducted the regular daily inspection of the BIO-5 Rasteniya-2 (“Plants-2”) experiment, including filling its water canister for the Lada-7 greenhouse as required.
At ~2:10pm EDT, the crew was scheduled for their eighth regular (nominally weekly) teleconference with the Lead Flight Director at MCC-H and TsUP/Moscow via S-band/audio, with phone patch between Houston and Moscow.
Last Wednesday (7/13) at 4:39am EDT, subset 3 (“lane 3”) of the SM’s Central Computer (TsVM) was voted out of the redundant triple set. The computer continues nominally in two-lane configuration. Cause of the drop-out is being assessed. TsVM restart is required to re-integrate all three lanes into the redundant set.
The results from John’s UOP-4 (utility outlet panel #4) load troubleshooting yesterday allowed the ground to clear all three remaining hardware pieces which the FE tested for use as needed. This activity ends the UOP-4 loads troubleshooting activities in general. The cause of the RPC (remote power controller) trip to UOP-4 in November 2004 is still unexplained.
