From ISS On-Orbit Status Report for 04/07/2010:
Yest kasaniye! At 4:17 PM GMT, Progress M-06M/38P docked successfully to the SM (Service Module) Aft port under KURS autopilot control, followed by a final DPO post-contact thrusting burn, docking probe retraction and hook closure ("sborka") after motion damp-out while the ISS was in free drift for ~20 minutes (4:17 PM to 4:37 PM GMT). At "hooks closed" signal, the SM returned to active attitude control, maneuvering the ISS to LVLH (Local Vertical/Local Horizontal) TEA (Torque Equilibrium Attitude) at ~4:37 PM GMT. Control authority returned to US Momentum Management at ~6:10 PM GMT. Russian thrusters were disabled temporarily during clamps install and leak check (6:10 PM to 8:10 PM GMT). [This was the second docking attempt after Friday's aborted docking, now traced to an interruption of the TORU radio signal by the SM's Klest/Simvol television system. The dropout of the TORU teleoperated rendezvous & docking system then generated the command "cancel dynamic operations" which aborted KURS automatic rendezvous mode and switched Progress to a safe, passive flightpath, as designed. For today's docking, TORU, which is usually in "hot standby" mode during KURS-controlled dockings, was not activated.]
Before docking, FE-4 Wheelock shut down the amateur/ham radio equipment (~1:05 PM GMT) to prevent RF (Radio Frequency) interference with the Progress KURS radio control system. [The protective shutters of the Lab, Kibo & Cupola science windows were already closed last night.]
For monitoring 38P rendezvous & docking, CDR Skvortsov & FE-2 Caldwell-Dyson had set up the Ku-band video "scheme" for covering the Progress docking, activating the FGB (Functional Cargo Block) based A31p SSC (Station Support Computer) laptop for the TV conversion to NTSC & Ku-band of the RS (Russian Segment) video signal from the SONY HDV camera via the MPEG-2 encoder from FGB & SM, in order to downlink "streaming video" packets via US OpsLAN and Ku-band.
Approach & docking as seen from the +X (backward facing) SM TV camera was monitored by Skvortsov on the SSC1 laptop using the NVIEWER (NASA Viewer) software application.
Tracy Caldwell-Dyson worked with Skvortsov to tear down and remove the MPEG-2 "schemes" streaming video downlink setup, then deactivated the conversion A31p laptop in the FGB.
From ~6:10 PM to 7:25 PM GMT, the crew conducted the standard one-hour leak checking of the docking vestibule and fuel/oxidizer transfer line interface between Progress and SM Aft.
The Russian crewmembers then:
• Opened the hatches (~7:25 PM GMT) and installed the QD (Quick Disconnect) screw clamps (BZV) of the docking & internal transfer mechanism (SSVP) to rigidize the coupling (Sasha).
• Performed the standard air sampling inside Progress with the Russian AK-1M air sampler (Fyodor).
• Powered down Progress (~8:05 PM) and installed the ventilation/heating air duct (Sasha).
• Dismantled the docking mechanism (StM, Stykovochnovo mekhanizma) between Progress and the SM Aft port (~8:25 PM to 9:25 PM GMT) [the StM being the "classic" probe-and-cone type, consisting of an active docking assembly (ASA) with a probe (SSh), which fits into the cone (SK) on the passive docking assembly (PSA) for initial soft dock and subsequent retraction to hard dock. The ASA is mounted on the Progress' cargo module (GrO), while the PSA sits on the docking ports of the SM, FGB and DC-1].
• Worked in the 38P vehicle to install the electronic LKT local temperature sensor commutator (TA251MB) of the BITS2-12 onboard telemetry measurement system and its PZU-1M ROM (Read Only Memory), using recycled boxes from stowage (Fyodor).
