All ISS systems continue to function nominally, except those noted previously or below. Sunday – Progress 33P Re-rendezvous day. Ahead: Week 7 of Increment 20.
CDR Padalka began his workday by attending to the current experiment session with the Russian/German TEKh-20 Plasma Crystal-3+ (Plazmennyi-Kristall/PK-3+) payload, activating the turbopump in the Service Module (SM)’s Transfer Compartment (PkhO) for keeping the vacuum chamber (ZB) in the SM Work Compartment (RO) evacuated. The turbopump will be deactivated again shortly before sleeptime. [Main objective of PK-3 is to study wave propagation and dispersion ratio in a dust plasma, i.e., fine particles charged and excited by HF (high frequency) radio power inside the evacuated work chamber, at a specified power of HF discharge, pressure, and a varied number of particles.]
The crew prepared for and then monitored the re-rendezvous & approach of Progress 33P at ~11:45am 1:15pm EDT (closest approach: 1:07pm), with –
FE-4 Thirsk closing the protective science window shutters in the Lab and Kibo JPM (JEM Pressurized Module),
FE-1 Barratt configuring & activating the A31p SSC (Station Support Computer) laptop in the FGB for the TV conversion to NTSC and Ku-band,
CDR Padalka checking out the RS (Russian Segment) video system, which uses the SONY HDV camera for transmitting over the MPEG-2 (Moving Pictures Expert Group 2) encoder from FGB & SM to downlink via U.S. OpsLAN and Ku-band in “streaming video” packets,
CDR configuring the STTS communications system for the rendezvous (and later restoring it to nominal mode),
FE-2 Wakata setting up the BRTK TVS video equipment for covering the Progress re-rendezvous and later deactivating it, and
Padalka & Romanenko preparing for the rendezvous and then closely monitoring the event from the SM.
[Purpose of the 33P re-rendezvous & approach was to verify the new passive KURS-P system antennas and TORU target installation accuracy at the SM PkhO (Service Module Transfer Compartment) zenith port. 33P, which undocked from the DC1 nadir port on 6/30, was to approach from ~200 km distance similar to the standard Soyuz approach, i.e., station keeping at ~130-200 m, then performing final approach to ~10-12 m (~1:07pm), before further approach is cancelled and the spacecraft backed out.]
After the event, FE-1 Barratt will dismantle the TV equipment and stow it away.
FE-3 Romanenko performed the routine daily servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the SM (Service Module), including the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP-Moscow.
Roman also checked up on the Russian POTOK-150MK (150 micron) air filter unit of the SM’s SOGS air revitalization subsystem, gathering weekly data on total operating time & “On” durations for reporting to TsUP-Moscow. [Regular daily SOZh maintenance consists, among else, of checking the ASU toilet facilities, replacement of the KTO & KBO solid waste containers and replacement of EDV-SV waste water and EDV-U urine containers.]
In the Kibo JPM (JEM Pressurized Module), FE-2 Wakata supported ground ops by starting the Ar (argon) gas from the CGSE (Common Gas Support Equipment) supply’s upper Ar GBU (Gas Bottle Unit).
FE-1, FE-4 & FE-5 have their weekly PFCs (Private Family Conferences) scheduled, via S-band/audio and Ku-band/MS-NetMeeting application (which displays the uplinked ground video on an SSC laptop), Frank at ~7:10am, Mike at ~2:40pm, Bob at ~6:00pm EDT.
FE-5 DeWinne connected the ITCS MTL (Internal Thermal Control System Moderate Temperature Loop) return umbilical with QD (Quick Disconnect) at the Lab CHeCS (Crew Health Care System) rack UIP (Utility Interface Panel) to provide cooling to the rack.
At ~10:05am, Frank powered up the SM's amateur radio equipment (Kenwood VHF transceiver with manual frequency selection, headset, & power supply) and at ~10:10pm conducted a ham radio session with students at the Euro Space Center (ESC) at Transinne, Belgium. [ESC is a residential (100 beds) US-licensed Space Camp for kids of ages 8-18. Transinne is near Bastogne in Belgium (of Battle of the Bulge fame, Christmas 1944). ESC also hosts a permanent Space Expo and a restaurant open to visitors as well as amateur radio club station. As in previous years, on Sunday, 7/12, the Euro Space Center organizes the Air Space Day, during which over 1000 people come and visit the center. The purpose of the event is to promote space and make the general public more aware of the different space related aspects.]
The crew completed their regular daily 2.5-hr. physical workout program on the CEVIS cycle ergometer (FE-1, FE-4, FE-5), TVIS treadmill with vibration isolation (CDR, FE-2, FE-3), RED resistive exercise device (CDR, FE-1, FE-2, FE-4, FE-5) and VELO cycle ergometer with bungee cord load trainer (FE-2). [The interim RED is being used in lieu of the ARED (Advanced RED) until the latter has had its damaged VIS (Vibration Isolation System) dashpot replaced and can be put back in service.]
BGA 2B Update: Yesterday, BGA 2B (Beta Gimbal Assembly 2B) on the port solar array was taken to Autotrack to test the rotational capabilities of the joint. The joint operated with better performance than was seen in previous days before it stalled. BGA 2B has been parked at 225 degrees which is a good config for both 33P Re-approach and 2J/A Docking. The MCC-H team is currently assessing the forward plan for BGA 2B operations.
