From ISS On-Orbit Status Report for 10/03/2011.
HTV-2 (H-II Transfer Vehicle-2) relocation from the Node 2 Zenith port (upward) to Nadir port (downward) was successfully accomplished by FE-5 Paolo Nespoli & FE-6 Cady Coleman with the SSRMS (Space Station Remote Manipulator System) in a lengthy operation. Nadir port-to-HTV vestibule outfitting and hatch opening are scheduled for tomorrow.
Early in the day, in preparation for the relocation of HTV-2, CDR Scott Kelly & Cady:
- Disconnected the remaining power jumper in the HTV PLC (Pressurized Logistics Carrier) vestibule & completed HTV thermal cover installation.
- Installed the Node 2 Zenith port CDC (Center Disk Cover), with CDC flap open.
- Checked CBM (Common Berthing Mechanism) latch clearance.
- Closed the Node 2 Zenith hatch.
Coleman then initiated the 2 hour 25 minute depressurization of the Vestibule between HTV and Node 2. [The 5-ft VAJ (Vacuum Access Jumper) with its ISA (Internal Sampling Adapter) was left connected and moved aside for the pressurization of the HTV/Node 2 Nadir vestibule later today.]
During the depress period, Kelly & Coleman cleared remaining stowage items at the Node 2 Nadir location to clear the hatch for the relocation. [The hatch was then set to Unlatch to minimize the probability of hatch mechanism jamming prior to HTV-2 relocate.]
For covering the HTV-2 robotics operations, Paolo activated the VSW (Video Streaming Workstation) and SSC-1 (Station Support Computer-1) laptops for downlinking converted NTSC MPEG-2 (Moving Pictures Expert Group-2) "streaming video" packets via US OpsLAN and Ku-band. [Was not received.]
Paolo also enabled the Cupola RWS (Robotics Workstation) UOP (Utility Outlet Panel) for power-up in Node 3, connected the UOP DCP (Display & Control Panel) power bypass cable at the Cupola RWS, and installed the CCR (Cupola Crew Restraint).
Scott powered up the CBCS (Centerline Berthing Camera System) at the Node 2 Nadir port and checked out the video system.
Scott & Cady then demated the Zenith CBM by removing its bolts and deploying the latches.
Afterwards, Paolo & Cady operated the Canadian SSRMS to unberth HTV-2 and maneuver it from the Zenith port to the RTL (Ready To Latch) stop at the Nadir port of Node 2, an activity taking several hours. [No exercise was allowed during this period.]
During the transfer, Scott used an internal camcorder to perform a careful survey of the HTV's PCBM (Passive CBM) out of the Node 2 Zenith CBM hatch to check for any FOD (Foreign Object Debris) on the mating surfaces.
With Scott monitoring CBM operations through confirmed First Stage & Second Stage Capture plus subsequent ABOLT (Acquire Bolts) driving, Cady & Paolo "limped" the SSRMS between First & Second Stage and finally released the robot arm's LEE (Latching End Effector). [Crew exercise was allowed only after ABOLTs was complete due to loads/dynamics flight rules.]
Afterwards, Cady disabled power to the Cupola RWS UOP in Node 3, while Scott removed & stowed the CBCS and visually verified closure of all four Node 2 Zenith CBM petal covers through the Cupola windows.
Paolo deactivated the VSW along with the additional laptop used for viewing in the Cupola, and then removed the CCR which had steadied and stabilized the weightless SSRMS operator.
Scott meanwhile cycled the Node 2 Nadir hatch latches to Closed and initiated vestibule pressurization and leak checking.
Later tonight, Scott & Cady are scheduled for Part 1 of Node 2 Nadir-to-HTV Vestibule Outfitting – opening the Nadir port hatch, removing the CDC, mating a power jumper (MPLM/HTV W6004) to HTV (already mated to Node) and installing a data jumper (MPLM 1553 LB-B W6002).
