All ISS systems continue to function nominally, except those noted previously or below. Day 9 of joint E16/E17 operations by CDR-16 Peggy Whitson, FE-1-16 Yuri Malenchenko, FE-2-17 Garrett Reisman, CDR-17 Sergei Volkov, FE-1-17 Oleg Kononenko and SFP/VC14 So-Yeon Yi. Day 191 in space for Peggy & Yuri.
Last day before Soyuz 15S undocking, with the ISS crew on an irregular wake/sleep cycle:
The E16/E17 crew rotation/handover period is running down. Whitson, Volkov, Malenchenko and Kononenko are completing their joined crewtime for dedicated (“functional”) CDR/CDR & FE/FE handover activities plus “generic” handovers where crewmembers are scheduled together to complete various designated standard tasks.
From the US voluntary “job jar” task list, after wakeup and before breakfast, FE-2 Reisman & SFP (Space Flight Participant) So-Yeon Yi again downloaded the SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) experiment data from their Actiwatches to the HRF-1 (Human Research Facility 1) laptop. Yi has been participating in SLEEP for NASA under a Space Act agreement with South Korea. Later tonight, CDR Whitson will work with her own, Garrett's and So-Yeon's Actiwatch, downloading their accumulated data to the HRF-1 laptop, initializing her unit for FE-2 Reisman, then stowing the SLEEP hardware and powering down the HRF1 laptop. [To monitor the crewmember's sleep/wake patterns and light exposure, crewmembers wear a special Actiwatch device which measures the light levels encountered by them as well as their patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days.]
For Peggy & Garrett, the second session with the biomed experiment INTEGRATED IMMUNE (Validating Procedures for Monitoring Crew member Immune Function) ended today with the CDR & FE-2 performing their final INTEGRATED IMMUNE blood and liquid saliva collection, assisting each other with the blood draw, photo-documented by Kononenko. The subjects' saliva return pouches and blood sleeves as well as the saliva collection kit were then stowed in the MELFI (Minus-Eighty Laboratory Freezer for ISS), which Reisman had prepared with ICEPACs before. [IMMUNE assessment, integrated with the Russian IMMUNO, is a 24-hr. test of human immune system changes, with the objective to investigate immune neuro-endocrine reactions in the space environment by studying samples of saliva, blood and urine before, during and after flight for changes related to functions like bone metabolism, oxidative damage and immune function, using collection kits and the biomedical (MBI) protection kit, to develop and validate an immune monitoring strategy consistent with operational flight requirements and constraints. The strategy uses both long and short duration crewmembers as study subjects. The saliva is collected in two forms, dry and liquid. The dry samples are collected at intervals during the collection day using a specialized book that contains filter paper. The liquid saliva collections require that the crewmember soak a piece of cotton inside their mouth and place it in a salivette bag; there are four of the liquid collections during docked operations. For cold storage, samples are secured in the MELFI. Also included are entries in a fluid/medications intact log, and a stress-test questionnaire to be filled out by the subject at begin and end. Urine is collected during a 24-hour period, conventionally divided into two twelve-hour phases: morning-evening and evening-morning.]
FE-1 Malenchenko, with assistance by CDR-17 Volkov, prepared for his return to Earth by spending about two hours in the Soyuz with packing and stowing of equipment, after transferring BTKh-1,-2, & -4 (Glycoproteid, MIMETIK-K & VAKTsINA-K) sample hardware in the “Luch-2” kit, the "Konyugatsiya" (BTKh-10, Conjugation) experiment in the Recomb-T kit from CRYOGEM-03M, and INTERLEUKIN-K (BTKh-20) to TMA-11.
Also transferred for return were the Russian payload TkhN-9 SVS (Self-Propagating High-Temperature Synthesis) equipment, the Japanese GCF-JAXA Crystallization Facility, the Russian SAMPLE experiment, and other payload items, with transfers logged in the IMS (Inventory Management System).
SFP So-Yeon Yi meanwhile closed out and transferred her experiments KAP01 (Growth & mutation of plant seeds) and KAP03 (Development of Bioreactor for use on the ISS).
FE-2 Reisman set up, programmed and verified the IWIS (Internal Wireless Instrumentation System) with its RSUs (Remote Sensor Units) and NCU (Network Control Unit) to record structural dynamics/vibrational data during the ISS free drift and Soyuz undocking periods. The departure will also be recorded by the external SDMS (Structural Dynamics Measurement System).
Garrett conducted the routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables.
Oleg Kononenko completed the daily IMS (Inventory Management System) 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).
The remaining crewmembers completed 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-17, FE-17), and RED resistive exercise device (FE-2).
Afterwards, Garrett & Oleg 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).
As Whitson, Malenchenko and Yi prepare to ingress Soyuz TMA-11, CDR Volkov is scheduled (at ~8:55pm) to configure the onboard communications system (STTS) for the undocking, both working to set up, check and maintain the VHF comm link from the TMA-11 SA to TsUP/Moscow via RGS (Russian Ground Site) and the comm system for Soyuz undocking and descent.
Work hours for the crew continued into the next day (4/19) in support of the Soyuz undocking and post-undocking activities, with sleep time beginning at 4:45am EDT.
If everything is nominal, the return to Earth of the TMA-11 spacecraft tomorrow morning will proceed along the following approximate event sequence (all times EDT):
