CDR Yuri Malenchenko and FE/SO Ed Lu continued cargo transfer operations from Progress 11P, tracking the movements with the IMS (inventory management system). [Some stowage location entries had to be corrected as per uplinked radiogram from Moscow.]

As part of regular weekly maintenance tasks, Malenchenko inspected the BRPK-1 air/liquid condensate separator of the SM's SRVK water processing system.

Yuri also completed the daily routine maintenance of the SM's SOZh environment control & life support system, and prepared the daily IMS "delta" file.

Ed Lu completed the periodic transfer of accumulated physical exercise data files of the TVIS treadmill, RED resistive exerciser and CEVIS cycle ergometer to the MEC (medical equipment computer), for subsequent downlink to the ground. [The data file transfers involve PCMCIA (portable computer memory card international adapter) cards from TVIS and CEVIS, plus the entries from the RED exercise log book, individually for each crewmember.]

Both crewmembers performed their regular daily exercise regimen on TVIS, CEVIS, RED and VELO bike with load trainer (for the CDR).

At 12:00 noon EDT, Ed Lu and Yuri Malenchenko, in colorful Hawaiian shirts, participated in two interactive televised PAO interviews (Ku-band & S-band) on KCRA-TV, Sacramento, CA, and CNN (Miles O'Brien), each one lasting about ten minutes.

Immediately thereafter, the two crewmembers downlinked a televised message to a graduate class of the Korolev Military Institute of Radio Electronics in Zhitomir, Ukraine, via US assets. The occasion of the congratulatory address was the cadets' graduation from the nearly 100 years old Institute and the conferral of their first commissioned rank. ["I would like to express my sincere gratitude to the head of the Institute, Major General Dmitri Vladimirovich Pyaskovsky, and to the professors and lecturers responsible for the tremendously difficult task of bringing up generations and generations of commissioned officers." The Ukrainian city of Zhitomir is also the birthplace of Sergei Korolev.]

After the installation of the electronic US-21 matching unit in the Progress vehicle yesterday (6/16), which connects the Progress motion control and DPO thrusters systems to the Service Module (SM) so that they can be commanded by the SM computer system (BVS), Moscow today ran the standard firing tests of the Progress approach and attitude control, thrusters. [At 12:00 am EDT, station attitude was handed over from XPOP to the Russian segment MCS (motion control system) for the tests, conducted from the SM MCS via the US-21 matching unit. Thruster manifold #1 (four jets) was tested first, at 1:36am, followed by manifold #2 (four jets) at 3:12am. Afterwards, control authority was returned to the U.S. CMGs for Momentum Management in XPOP.]

MCC-M/TsUP also performed the regular adjustment of onboard time via Regul uplink, followed by onboard clock synchronization and daily state vector uplink.

Starting this morning at 12:30am EDT and ending at about 7:30am, MCC-Houston and its support group in Moscow (HSG) performed a BCC (backup control center) activation test, which did not involve the ISS crew. [BCC utilizes the HSG command server and telemetry server. In test mode, command function was transferred to HSG (as BCC) for sending a single PPCP (preplanned command packet) to MCC-M/TsUP. TsUP activated ACT (American contingency telemetry) via cyclogram for uplinking the PPCP to the ISS with HSG confirming successful receipt. TsUP commanding to the Russian segment (RS) via U.S. S-band as well as MCC-H-to-TsUP flow of status telemetry were not affected, but MCC-H had no real-time telemetry and command capability via Russian ground stations (RGS) during the periodic testing.]

The Science Officer was praised by POC (Payload Operations Center) on his hard work yesterday performing the 30-day functionality test of the HRF GASMAP (Human Research Facility/Gas Analyzer System for Metabolic Analysis Physiology). [Good run time was obtained, and the check will be done again in 30 days.]

SM battery #4 has been disconnected again. This leaves seven good 800A storage units.

A conjunction (close encounter) with the SNOE satellite (Student Nitrous Oxide Explorer, object #25233) occurred this morning at 8:33am EDT. The object had been tracked for the last few days. Since its predicted radial miss distance remained very stable at ~400m since Saturday morning (6/14), no action was required.

The recent tests, on 6/7, to view ISS structure and components (in an assessment of the optical inspection capability of ISS cameras for Shuttle imaging) showed up some problems with camera zooming and focusing which are currently under review and scrutiny by ground specialists.

After the ISS attitude transition on 6/12, the crew noticed a small, shiny, free-floating metallic object about 30 m (100 ft) from the Lab nadir window, moving very slowly away from the ISS. The leading theory was that the object is a cable label. [A photo of a cable label, uplinked from the ground, was later examined by Ed Lu. He confirmed the possibility that the object he saw indeed could have been a cable label. Further identification of the object by ground teams is still underway. Limited tracking data the object on 6/12 showed it below the ISS and 1.7 km in front. Preliminary predictions indicated it was slowly separating, and the specialists did/do not believe it poses a re-contact hazard to the station. Ed Lu's image of the object can be seen at http://spaceflight.nasa.gov/station/images/ISS007E06886.jpg]

On 6/11, during Progress ingress activities, Malenchenko reported that the air duct and fan assembly used to ventilate the cargo ship could not be set up due to a missing connector. With MCC-M agreement, he installed only the air duct, relying on an upstream fan to provide sufficient ventilation. The connector was found later, but the fan could still not be installed due to (temporarily) limited room. It was to be installed after sufficient Progress unloading.

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 Lake Nasser, Toshka Lakes (the crew had a good pass to look right of track for a mapping view of the record high water levels in Lake Nasser and the Nile River), Eastern Mediterranean Smog (on this descending pass in fading light towards the Middle East, the crew was to look right of track over the eastern Med towards the Egyptian coast and the Nile Delta. The ground is interested in views of sunlit aerosol layers enhanced over the darker water), Western Mediterranean Dust and Smog (as a cold front plows into the Iberian Peninsula from the west, strong southerly winds over Algeria are expected to lift dust northward over the western Med. As the ISS crossed northern Spain, the crew was to start looking obliquely right of track for sunlit dust plumes), Wichita River (the ISS approached this target with fair weather and good illumination from the southwest. Looking just right of track to document land use and stream patterns between the city of Wichita Falls and the Red River), and The Dalles (LEWIS & CLARK SITE: As ISS passed over southern Washington, the crew was to try to look right of track and map the lower Columbia River. Of particular interest is the area known as The Dalles, a great southward arch in the river before it cuts through the Cascade Range).
