2008.03.31 - ISS On-Orbit Status 03/31/08

Underway: Week 24 of Increment 16.

As suggested on his voluntary 'job jar' task list, after wakeup and before breakfast FE-2 Garrett Reisman completed his fourth 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.)

Preparatory to today's ATV1 'Jules Verne' Demo Day 2, CDR Whitson closed the Lab science window shutters as protection against Russian thruster contamination, configured the designated A31p laptop in the FGB for transmitting analog & digital video of the RS (Russian Segment) activities from the MPEG-2 (Moving Pictures Expert Group 2) encoder, downlinked via U.S. OpsLAN and Ku-band in 'streaming video' packets, and later deactivated the A31p after the rendezvous activities.

FE-1 Malenchenko meanwhile readied the KL-154 'Klest' television equipment from the SM (Service Module)'s ATV TV control console (BRTK-PU).

ISS attitude control authority was handed over to RS MCS (Motion Control System) thrusters at 7:37am EDT for maneuvering the station to ATV1 rendezvous attitude (8:11am). (Rendezvous attitude: LVLH (Local Vertical Local Horizontal) +XVV (+x-axis in velocity vector), YPR (Yaw, Pitch, Roll) = 0,0,0. Later, after returning to TEA (Torque Equilibrium Attitude) at ~1:25pm, control was returned to U.S. momentum management at 1:55pm.)

After preparing for the second ATV1 rendezvous demo, Malenchenko & Whitson activated and tested the MBRL/PCE (Proximity Communications Equipment) Space-to-Space Radio hardware of the ASN-M satellite navigation system in the SM, then monitored the approach, station-keeping and subsequent escape maneuver of the automated ATV1, recording times and performance data. All planned maneuvers were completed entirely nominally. (Demo Day 2 involved Jules Verne closing in on ISS from the S-1/2 waypoint about 40km behind (at 8:26am EDT), arriving via Hohmann transfer at the S2 station-keeping (holding) point at a distance of ~3500m behind ISS (~9:57am) for subsequent testing of HOLD & RETREAT commands through the PCE. Approach continued to the second holdpoint, S3 at ~249 m (~11:10am), then to S4 at ~19m (by 12:13pm), followed by inching closer to S41 (12m) for more HOLD & RETREAT command tests, next retreating to S4 and finally performing the actual ESCAPE maneuver of 4 m/sec delta-V (~12:38pm) to take the vehicle away from the station, closing out Demo Day 2 ops at ~12:45pm. Background: Navigation between S-1/2 and S3 is based on GPS (Global Positioning System) data of the ISS which are received by the ATV and compared with ATV GPS data. From S3 to docking, ATV employs two sophisticated measuring systems for range, line-of-sight angles & relative attitude,- the VDM (Videometer) and Telegoniometer (TGM), which use lasers illuminating RVTs (Rendezvous Targets) on the aft end of the SM, installed previously on Russian spacewalks. The ISS crew is prohibited by Flight Rule to view the ATV through cameras or binoculars when inside a range of 5 m, and also not with the naked eye from SM window 26, until VDM & TGM are powered off, to prevent eye damage from non-visible light.)

Afterwards (~1:30pm), Peggy & Yuri were scheduled for a debriefing teleconference with the ground to review the ground/crew communications and determine if anything needs to be changed before Docking Day next Thursday (4/3).

The FE-1 performed the periodic (generally monthly) service of the ESA/RSC-Energia experiment ALTCRISS (Alteino Long Term monitoring of Cosmic Rays on the ISS), removing the PCMCIA memory card #945 and replacing it with #941 on the AST spectrometer on DC1 panel 402 to continue operations, then testing #945 on the RSK1 laptop for data quantity and total size of files, before stowing it for later return to Earth. Yuri also photographed the future new location of the AST in the FGB (beginning on 4/8).

Malenchenko also started his first session of the Russian MedOps MO-2 protocol which calls for 24-hour recording of his ECG (electrocardiogram). (For the ECG recording, Yuri donned the five-electrode Holter harness that read his dynamic (in motion) heart function from two leads over 24 hours and record data on the Kardioregistrator 90205 unit. CDR Whitson assisted her crewmate in the harness donning (and will also do so in tomorrow's doffing).)

FE-2 Reisman worked in the JLP (Japanese Experiment Module Experiment Logistics Module Pressurized Section), first performing the periodic status and shell temperature check from the MKAM (Minimum Keep-Alive Monitor), then briefly activating the MKAM fan and relocating the module's PBA (Portable Breathing Apparatus) from its location COL1PF in the COL (Columbus Orbital Laboratory) to the JLP endcone. After troubleshooting the wiring and fixture of the failed JLP GLA (General Luminaire Assembly) P2A, Garrett conducted the periodic inspection of the PEP PFE (Portable Emergency Provisions/Portable Fire Extinguisher), then deactivated the JLP fan again and returned the PBA to the COL1PF location.

Reisman also undertook the monthly FDS (Fire Detection & Suppression) PEP safety inspection/audit in the other ISS modules besides JLP. (The IMS (Inventory Management System)-supported inspection involves verification that PFEs (portable fire extinguishers), PBAs (portable breathing apparatus), QDMAs (quick-don mask assemblies) and EHTKs (extension hose/tee kits) are free of damage to ensure their functionality, and to track shelf life/life cycles on the hardware (QDMA harness inspection was not required this time).)

Malenchenko had another hour reserved for transferring more discarded cargo to the Progress 28P and stowing it according to detailed plan in the logistics spacecraft-turned-trash can, to be jettisoned next week (4/7).

FE-2 Reisman was scheduled to initiate, later terminate, a total-pressure adjustment of the cabin atmosphere with air from 28P storage.

Garrett also unstowed and set up the PFE-OUM (PFE-Oxygen Uptake Measurement) equipment on the HRF-2 (Human Research Facility 2) rack, including the HRF PFM/PAM (Pulmonary Function Module/Photoacoustic Analyzer Module), Mixing Bag System and GDS (Gas Delivery System), for his first PFE-OUM protocol session tomorrow. (The Periodic Fitness Evaluation with Oxygen Uptake Measurement experiment, using the CEVIS ergometer for workout, demonstrates the capability of crewmembers to perform periodic fitness evaluations with continuous oxygen consumption measurements within 14 days after arrival on ISS, and once monthly during routine PFEs. Once the capability of the pulmonary function system (PFS) to perform PFEs is verified, crewmembers will be able to integrate their monthly PFE with oxygen consumption measurements to fulfill the requirement for cardiovascular fitness evaluations during long-duration space flight.)

The FE-1 performed 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.)

In the Lab, Peggy Whitson worked on the MELFI (Minus-Eighty Laboratory Freezer for ISS) rack, preparing box modules in Dewar 1, Tray C, for easier Double Coldbag packing, by removing obstructing Velcro straps.

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 (FE-2), TVIS treadmill (CDR, FE-1/full time), and RED resistive exercise device (CDR, FE-2).

Afterwards, Garrett downloaded the crew's exercise data file 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).

Reisman had another 60 minutes for himself for general orientation (station familiarization & acclimatization), as is standard daily rule for the first two weeks after starting station residency.

Peggy Whitson spent about an hour on end-of-increment cleanup and departure preparations. (Instructions on packing of return items and a keep vs. trash list were uplinked for assisting Yuri and Peggy in their preparing for their return in the severely downmass-limited Soyuz Descent Module. Trashed items will be stowed in the Orbital Module, to be separated along with the Instrumentation/Propulsion Module prior to atmospheric entry.)

Working off his suggested 'time permitting' task list, Yuri Malenchenko completed a series of regular servicing tasks, viz.: -

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
Conducting the daily IMS maintenance, updating/editing its standard 'delta file' including stowage locations, for the regular weekly automated export/import to its three databases on the ground (Houston, Moscow, Baikonur).
ATV Update (Flight Day 22): In preparation for today's successful Demo Day 2 rendezvous & approach program, the ATV1 yesterday began phasing back to the rendezvous initiation point S1/2 at ~30km behind the ISS, performing the following six maneuvers, all of which were reported to be nominal:

TA1: 8:22:06pm on 3/29; delta-V: 1.70 m/s
TA2: 9:08:06pm; delta-V: 7.32 m/s
TA3: 9:53:54pm; delta-V: 1.23 m/s
TB1: 4:34:28pm on 3/30; delta-V: 5.18 m/s
TB2: 5:18:27pm; delta-V: 8.16 m/s
TB3: 6:08:59pm; delta-V: 2.50 m/s.
The IMMT (ISS Mission Management Team) afterwards gave the GO for Demo Day 2.
