ISS On-Orbit Status 03/30/08

Sunday -- off-duty day for CDR Whitson, FE-1 Malenchenko and FE-2 Reisman except for housekeeping and voluntary work.

Ahead: Week 24 of Increment 16. Flight Control to Crew: 'Everyone at the ATV-CC (as well as MCC-M and MCC-H) could not be more pleased with how Demo Day 1 went!'

From his voluntary 'job jar' task list, after wakeup and before breakfast FE-2 Garrett Reisman completed his third session with the SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) experiment software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop. (To monitor the crewmember's sleep/wake patterns and light exposure, Garrett wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days.)

Also before breakfast, having reached the FD15 (Flight Day 15) mark in his flight, Reisman performed the last sampling of his first session with the NASA/JSC experiment NUTRITION w/Repository, collecting a final urine sample upon wakeup for storage in the MELFI (Minus-Eighty Laboratory Freezer for ISS). The sampling kit was then stowed away. (The current NUTRITION project is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight. It includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes, expanding the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

The crew conducted the regular weekly three-hour task of thorough house cleaning. ("Uborka", normally done on Saturdays, includes removal of food waste products, cleaning of compartments with vacuum cleaner, damp cleaning of the Service Module (SM) dining table, other frequently touched surfaces and surfaces where trash is collected, as well as the FE's sleep station with a standard cleaning solution; also, fan screens and grilles are cleaned to avoid temperature rises. Special cleaning is also done every 90 days on the HEPA (high-efficiency particulate air) bacteria filters in the Lab. Additionally, as part of the weekly cleaning, Malenchenko performs an inspection of structural elements, cables and instruments behind SM panels for moisture.)

Later, the FE-1 completed the routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables plus the weekly collection of the toilet flush counter (SPK-U) and water supply (SVO) readings for calldown to TsUP/Moscow. (Regular daily SOZh maintenance consists of replacement of the KTO & KBO solid waste containers, replacement of an EDV-SV waste water and EDV-U urine container, replacement of the KOV EDV at the SKV-2 air conditioner for the Elektron-intended water, and processing U.S. condensate water as it becomes available in a filled CWC from the Lab humidifier.)

Yuri also gathered weekly data on total operating time & 'On' durations of the Russian POTOK-150MK (150 micron) air filter unit of the SM's SOGS air revitalization subsystem for reporting to TsUP.

Whitson & Malenchenko conducted another OBT (Onboard Training) session, Part 2, for ATV1 Approach & Docking Demo Day 2 tomorrow (3/31), reviewing RODF (Russian Operations Data File) material and running a number of scenarios, including malfunctions, on the ATV simulator application, supported by S-band tagup with ground engineers.

In preparation for the upcoming Japanese CW/RW (Cell Wall/Resist Wall) experiment, FE-2 Garrett Reisman
replaced eight ECs Experiment Containers) on the centrifuges of the EMCS (European Modular Cultivation System) facility with different ECs. (The EMCS rack contains two rotating centrifuges that can support a wide range of small plant & animal experiments under partial gravity conditions. On Rotor A, the new ECs for CW/RW are EC92 in position A1, EC95 at A2, EC94 at A3, EC96 at A4, on Rotor B - EC97 in position B1, EC99 at B2, EC98 at B3, and EC100 at B4. The removed ECs were stowed.)

With the U.S. CDRA (Carbon Dioxide Removal Assembly) deactivated by the ground early this morning (~3:15am-8:15am EDT) and its cooling no longer required, Whitson demated and took down the ITCS LTL (Internal Thermal Control System/Low Temperature Loop) jumper at the CDRA-supporting LAB1D6 rack. (After Peggy's troubleshooting on 3/28, CDRA was operated for a day, but ground engineers could not resolve the elevated Precooler differential pressure (dP) offset between half-cycle 1 & half-cycle 2 operations. The anomalous dP signature has not been explained yet, despite several days of troubleshooting. Ground teams are now discussing further troubleshooting options.)

Working off his suggested 'time permitting' task list, Yuri Malenchenko completed a series of regular maintenance tasks for today, by -

Conducting his tenth and final Increment 16 run of the Russian DZZ-2 "Diatomeya" ocean observations program (using the NIKON F-5 digital still camera with 80-200 mm lens and the SONY PD-150P camcorder at medium zoom, Yuri focused on color bloom patterns, swirls, wakes of subsurface waves, ocean water level drop, smoothing lanes in wave fields, and sudden cloud pattern anomalies in the Atlantic and Indian oceans);
Performing another session of the Russian GFI-8 "Uragan" (hurricane) earth-imaging program (using the NIKON D2X still camera and the Japanese HDV (High Definition) video camera provided by SFP Charles Simonyi to shoot imagery of icebergs in the southern portion of the Atlantic ocean, Patagonian glaciers, coastal & mountain areas of Columbia, and the cities of Palmira, Bogotá and coastal cities on the Atlantic);
Supporting the BIO-5 Rasteniya-2 ("Plants-2") experiment, which researches growth and development of plants (peas) under spaceflight conditions in the Lada-12 greenhouse from IBMP (Institute of Bio-Medical Problems {Russian: IMBP}), by monitoring the greenhouse, taking pictures and downloading them to the ground;
Performing the regular daily checkup on the Japanese experiment GCF-JAXA (Granada Crystallization Facility) in the Russian TBU incubator, maintained at +20 degC, including a temperature check on its ART (automatic temperature recorder), and
Completing the periodic collection & deletion of readings on the MOSFET (metal oxide semiconductor field-effect transistor) radiation sensor reader/display of the RBO-3-2 Matryoshka-R antroph-amorphous (human torso) "phantoms" located inside the station for sophisticated radiation studies, collecting radiation measurements every 15 minutes around the clock.
The crewmembers performed their regular 2.5-hr. physical workout program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (CDR), TVIS treadmill (FE-1/full time, FE-2), and RED resistive exercise device (CDR, FE-2).

ATV Update (Flight Day 21): After a highly successful Demo Day 1 rendezvous & approach program yesterday, the ATV1 last night was 120 km in front of and 6.5 km below the ISS. Jules Verne continued to phase in front of ISS at a rate of ~60 km per rev until 8:21pm EDT, when it began coming back for Demo Day 2 tomorrow.
The rendezvous consisted of the following ten maneuvers, all of which were reported to be nominal:

TV1: 2:36:30am EDT; delta-V: 2.74 m/s
TV2: 5:13:36am; delta-V: 2.34 m/s
TV3: 6:10:08am; delta-V: 1.53 m/s
IF1: 8:39:20am; delta-V: 0.58 m/s
IF2: 9:25:23am; delta-V: 0.12 m/s
IF3: 10:10:31am; delta-V: 0.55 m/s
HM1: 11:10:15am; delta-V: 1.53 m/s
HM2: 11:25:44am; delta-V: 0.17 m/s
HM3: 11:41:14am; delta-V: 0.27 m/s
HM4: 11:46:44am; delta-V: 2.05 m/s.
At Hold point S2 (~3500 m behind ISS), the ATV performed stationkeeping from 11:56:45am to 1:30:11pm. During this time, the crew successfully performed the HOLD and RETREAT command path test. In addition, the Kurs system was activated and used to collect data for comparison with the ATV's RGPS system. The rendezvous completed with a successful ESCAPE maneuver that began at 1:30:11pm, with a delta-V of 4.03 m/s. (Between maneuvers TV1 & TV2, PDE-1 (Propulsion Drive Electronics #1) was disabled by the FDIR (Fault Detection, Isolation & Recovery) system due to a thermal delta temperature threshold violation. ATV-CC/Toulouse attempted to reintegrate the PDE, but during the reintegration the FDIR deactivated the PDE a second time for the same temperature threshold violation. Due to an unrelated concern regarding the procedure for reintegrating PDE-1, ATV-CC decided to wait until after the completion of TV2 & TV3 before reintegrating PDE-1. As a result, TV2 & TV3 were performed in a three-PDE configuration. Following TV3, PDE-1 was successfully reintegrated.)
