All ISS systems continue to function nominally, except as noted previously.  Sunday, another rest day for the station residents.  Ahead: Week 12 of Increment 7.  [Today 34 years ago, on July 20, 1969, the “Eagle” of Apollo 11 landed on the moon, carrying Neil Armstrong and Buzz Aldrin, while the “Columbia” CSM mothership with Michael Collins kept circling the moon, awaiting their safe return.]

CDR Yuri Malenchenko collected the weekly data readings of the Service Module (SM)’s toilet flush counter readings (with inspection of the SP urine collection and pretreat assembly) and SVO water supply status counter readings, both for calldown to MCC-M/TsUP.

Malenchenko also conducted the periodic inspection of the Elektron oxygen generator’s VM gas/liquid system for obstructing air bubbles that may linger after IFMs (in-flight maintenances).

Yuri terminated the bake-out cycle on the BMP micropurification system’s channel 2, moding the channel back to Purify.  This restored both filter beds to Purify mode.  [The regeneration of the air purifier filter beds is repeated every 20 days.  Each bakeout to space vacuum takes about 24 hours.]

The CDR then performed the daily routine maintenance on the SOZh life support system which comprises the water supply equipment, food supply subsystem (SOP), and sanitary hygiene equipment (SGO).  [Maintenance generally consists of inspection of fluid lines/connections and filter replacement.]

FE/SO Ed Lu prepared the daily delta file for automatic export/import to update the IMS (inventory management system) database.

Malenchenko attended to his regular daily checkup of his BIO-5 Rasteniya-2 (“Plants-2”) experiment which investigates growth and development of plants under spaceflight conditions in the SM’s Lada-2 greenhouse.

Yuri Malenchenko held a teleconference with fellow cosmonauts at TsUP via VHF/audio..

Both crewmembers worked out in their daily 2.5-h program of physical exercise, on TVIS treadmill and RED expander.

The crew had their the weekly PFCs (private family conferences), via S-band/audio.

Working off his Russian task list, the CDR today had another photography session for the Diatomeya ocean observations program.  [Today’s target was the Falkland-Patagonian fishing region.]

Today’s CEO (crew earth observation) targets, no longer limited in the current LVLH attitude and including the targets of the Lewis & Clark 200-year memorial locations, were Melbourne, Australia (nadir pass), Philadelphia, Pennsylvania (NIGHT PASS.  Nadir view possible between cloud masses), Brasilia, Brazil (nadir pass), Rio de Janeiro, Brazil (nadir pass), Las Vegas, Nevada (NIGHT PASS.  Nadir pass), Phoenix, AZ (NIGHT PASS.  Nadir pass), Tucson, Arizona (NIGHT PASS.  Nadir pass), Patagonian Glaciers (looking on the “dry” eastern slopes for detailed views of glacier tongues at the mountain front.  Winds move clusters of icebergs from point to point in the large glacier-foot lakes [lake depressions were cut by glaciers during several ice advances in the last ice age], Baghdad, Iraq (NIGHT PASS), Gui-shen, China (suggesting a broad, contextual view on this first good pass.  This will assist the ground later in locating more detailed views.  Looking nadir and a touch left along the coast of Bohai Bay), and Ed’s Hill, New Zealand (suggesting contextual view for this first good pass: looking left along the coast of North Island).
