Half-day rest for CDR Volkov, FE-1 Kononenko and FE-2 Chamitoff.

Crew Sleep Cycle Adjustments: Crew wake/sleep cycle today is back on normal (2:00am-5:30pm) but will shift forward again starting tomorrow morning, by 3.5 hrs, throughout next week for the Orlan EVA on 7/10: wakeup - 5:30am, sleep - 9:00pm EDT.

Oleg Kononenko started his workday by taking the periodic readings of potentially harmful atmospheric contaminants in the SM (Service Module), using the CMS (Countermeasure System), a component of the GANK-4M Real-Time Harmful Contaminant Gas Analyzer suite, which uses preprogrammed microchips to measure H2CO (Formaldehyde, methanal), CO (Carbon Monoxide) and NH3 (Ammonia), taking one measurement per microchip. Today's measurements also looked for O3 (Ozone), C6H6 (Benzene) and NO2 (Nitrogen Dioxide), using special chips. (CMS is a subsystem of the Russian SKDS Pressure Control & Atmosphere Monitoring System.)

Later, the FE-1 used the SOGS GANK-4M system for taking and recording atmospheric readings. (GANK tests for Methane (CH4), NH3, CO, H2CO, Nitrogen Oxides (NO, NO2), Hydrogen Chloride (HCl), Hydrogen Fluoride (HF), and Hydrogen Cyanide (HCN).)

Kononenko also conducted a search for a spare O2 transducer for the IK0501 GA (gas analyzer), and a cap to install on it. (IK0501 is an automated system for measuring CO2, O2, and H2O in the air as well as the flow rate of the gas being analyzed).

Before sleep time tonight, the CDR will take measurements for the regular atmospheric status check for ppCO2 (Carbon Dioxide partial pressure) in the Lab, SM (at panel 449) and COL (Columbus Orbital Laboratory), using the hand-held CDMK (CO2 Monitoring Kit, #1002). (The battery pack is to be replaced with the one from unit #1009 if necessary.)

For Gregory Chamitoff, it was Day 2 of the two-day IFM (Inflight Maintenance) for refilling the two coolant loops of the ITCS (Internal Thermal Control System). (After first backing out of the safety steps put in place last night, the FE-2 then used the FSS (Fluid System Servicer) with its FCPA (Fluid Control Pump Assembly) to charge the LTL & MTL PPA (Low Temperature Loop & Moderate Temperature Loop Pump Package Assembly) accumulators as well as the spare ITCS CSA (Coolant Sampling Adapter). Afterwards, the FSS plus jumpers were drained and purged to vacuum, then stowed away. The coolant refill of the accumulators became necessary due to the recent installation of the Lab AmiA (Antimicrobial Applicator) by Karen Nyberg during 1J and the leak at the LTL supply QD (Quick Disconnect). The PPAs are located in the LAB1P6 & LAB1S6 racks. The refill of the spare CSA anticipates its use in the Kibo JPM: since both JEM ITCS CSAs were deleted from the 1J manifest, the plan is to eventually install the spare onboard CSA in the JPM to take samples until the JEM Adapters are delivered on a later mission.)

Chamitoff also conducted the monthly FDS PEP (Fire Detection & Suppression/Portable Emergency Provisions) safety inspection/audit in the ISS modules. (Today's inspection also covered the QDMA (Quick-Don Mask Assembly) harnesses, including those that had not been unpacked yet. In addition, photo documentation of all PBA (Portable Breathing Apparatus) and PFE (Portable Fire Extinguishers) gauges was required. The IMS (Inventory Management System)-supported inspection involves verification that PFEs, PBAs, QDMAs and EHTKs (Extension Hose/Tee Kits) are free of damage to ensure their functionality, and to track shelf life/life cycles on the hardware.)

Volkov & Chamitoff completed another monthly session (Sergey's third, Gregory's first) of the CHeCS (Crew Health Care Systems) emergency medical operations OBT (On-Board Training) drill, a 30-min. exercise to refresh their CMO (Crew Medical Officer)'s acuity in a number of critical health areas. Sergey's proficiency drill today focused on nosebleed treatment, Greg's on eye treatment. (The HMS (Health Maintenance Systems) hardware, including ACLS (Advanced Cardiac Life Support) equipment, may be used in contingency situations where crew life is at risk. To maintain proficiency, crewmembers spend one hour per month reviewing HMS and ACLS equipment and procedures via the HMS and ACLS CBT (computer-based training). The training drill, each crewmember for him/herself, refreshes their memory of the on-orbit stowage and deployment locations, equipment etc. and procedures.)

CDR Volkov had another 30 min reserved for relocating and stowing common trash into the ATV1 (Automated Transfer Vehicle) 'Jules Verne'.

Continuing the extended leak checking of the spare BZh Liquid Unit (#056) for the Elektron O2 generator, Kononenko charged the unit once again with pressurized N2 from the BPA Nitrogen Purge Unit (#23) to 1 atm (1 kg/cm2). The last test pressurization to monitor for leakage was on 5/22. (During Elektron operation, the inert gas locked up in the BZh has the purpose to prevent dangerous O2/H2 mixing. A leaking BZh cannot be used.)

Continuing Orlan preparations for the spacewalk on 7/10, Oleg installed the battery for powering the US wireless TV camera (ERCA/EMU RF Camera Assembly) in the BRTA-1M telemetry systems unit of Orlan-M suit #26, with cable routing, then covered BRTA-1M & cables with MLI (Multi-Layered Insulation), fastened down with Kapton tape.

On the US REBA (Rechargeable EVA Battery Assembly), also used on the Orlan, the FE-1 worked with Kapton tape, scissors and tape measure to jerry-rig an extension for the pull tab of the REBA which allows activation of the battery once it is installed in the Orlan.

Volkov performed 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).

Kononenko completed the routine maintenance of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM, including ASU toilet facilities systems/replaceables.

The crew worked out according to their regular 2.5-hr. physical exercise protocol (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS (FE-2), TVIS treadmill (CDR, FE-1), RED resistive exerciser (CDR, FE-1, FE-2) and VELO bike with bungee cord load trainer (CDR, FE-1). Afterwards, Oleg transferred the exercise data file to the MEC (Medical Equipment Computer) laptop for downlink, including 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).

This morning at ~4:15am EDT the CDR & FE-1 linked up with TsUP-Moscow stowage specialists via S-band to conduct the weekly IMS tagup, discussing stowage issues, equipment locations, Progress cargo transfers and ATV trash stowage.

At ~4:25am, the crew held the regular (nominally weekly) tagup with the Russian Flight Control Team (GOGU/Glavnaya operativnaya gruppa upravleniya = 'Main Operative Control Group'), including Shift Flight Director (SRP), at TsUP-Moscow via S-band/audio, phone-patched from Houston and Moscow.

At ~9:00am, Sergey & Oleg downlinked a PAO TV message of greetings and congratulations to an International Conference on Mental Recovery, to be held on July 2-4 in Moscow, organized by Academician N. N. Burdenko of the Scientific & Research Institute of Neurosurgery at M. V. Lomonosov Moscow State University, and the World Federation of Neurosurgical Societies. (' €¦Space and the human brain are the two vast, hardly fully researched universes, requiring more studies to discover the essence of all their processes. To reach their goals, space researchers and brain scientists-neurosurgeons, are taking advantage of cutting-edge technology and procedures. Some are looking into the depths of the Universe, trying to resolve the mysteries of planets and interstellar matter. The others are trying to learn about higher mental functions and dynamics on the cellular and molecular levels. We, the cosmonauts, are always aware of the doctors' attention to our health, well-being, and mental state. It is a well-known fact that medical doctors participated in numerous flights aboard space vehicles and orbital stations. We always assist our colleagues in conducting medical space experiments, in human bio-medical research in space flight €¦ We wish you new scientific discoveries and tangible achievements, every success in your noble activities, good health, well-being, happiness and prosperity to you and your loved ones.')

At ~4:00pm, the ISS crew is scheduled for their regular weekly tagup with the Lead Flight Director at JSC/MCC-H via S-band/audio. (S/G-2 (Space-to-Ground 2) phone patch via SSC (Station Support Computer)).

At ~5:20pm, getting ready for sleep time, Sergey will again set up the Russian MBI-12 SONOKARD (Sonocard) payload and start his 5th experiment session, using a sports shirt from the SONOKARD kit with a special device in the pocket for testing a new method for acquiring physiological data without using direct contact on the skin. Measurements are recorded on a data card for return to Earth. (SONOKARD objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.)

WRM Update: An updated Water Recovery Management 'cue card' was uplinked overnight for the crew's reference. (The new card (17-0002O) lists 36 CWCs (~1365.2 L total) for the four types of water identified on board: technical water (650.6 L, for Elektron, flushing, hygiene, incl. 509.4 L non-usable water because of Wautersia bacteria), potable water (706.7 L, incl. 260.6 L currently on hold), condensate water (0 L), waste/EMU dump and other (7.9 L). Wautersia bacteria are typical water-borne microorganisms that have been seen previously in ISS water sources. These isolates pose no threat to human health.)

ATV Hygiene Use: Due to some health concern about microbial/fungal growth in the FGB, an agreement has been reached with ESA to allow crewmembers to perform their hair and body washing in the ATV (away from sensitive equipment) as long as it is available. Other hygiene activities (shaving, hair cutting, fingernail clipping, etc.) will continue to be done near air filter intakes elsewhere on the station, not in the ATV.

EVA-20a Timeline Preview: The Orlan EVA-20a by Volkov/EV1 & Kononenko/EV2 on 7/10 is scheduled to begin at ~2:18pm EDT (DC1 EV hatch open), to last an estimated 6 hrs. During the spacewalk, EV2 will be riding on the DC1-based Strela 1 crane, operated via hand crank by EV1. Main objective is the inspection of the Soyuz TMA-12 spacecraft at its first separation plane (Plane I) followed by removal of one pyrobolt for return to Earth. Before removing the separation bolt, Oleg will install temporary protective covers on the spacecraft's DPO attitude control thrusters, open up the MLI (Multi-Layer Insulation), demate the pyrobolt's electrical connector and cut the wiretie between the pyrobolts. MLI will then be reattached and the covers removed again. If enough time remains after the Soyuz activity, the spacewalkers will also install a docking target (for the new MEM module) on the SM PkhO (Transfer Compartment) exterior.
(Background: Before their separation, Descent Module (SA) & Instrumentation Compartment (AO) are connected by five locks, each 'zamok' containing two pyrobolts (explosive bolts) with individual electrical connection, of which only one needs to fire to release the lock. The locks are equally spaced around the 360-degree circumference of the separation plane, i.e., 72 deg apart. After the five locks have released, five spring-loaded pushers, also equally spaced, separate the two modules by spring force. Each lock and pusher is located at the apex of two triangularly arranged aluminum pipes, i.e., altogether 20 inclined pipes, which make up the open truss structure between the modules.)

CEO (Crew Earth Observations) photo target uplinked for today was St. Louis, Mississippi floods (Dynamic event. Sun and cloud with isolated thunderstorms are forecast for the Mississippi valley in the vicinity of St Louis. Looking left for the Mississippi River floodplain where many counties are under flood warnings north of St. Louis, and now increasingly south of St. Louis.)
