Some more info on the RODK test from ISS On-Orbit Status Report for 21/11/2011:

When hooks have opened and 27S has been pushed out by spring force (delta-V ~0.12 m/s), Soyuz CDR Sergey Volkov will activate the RODK for its test, perform the first manual separation burn at ~15-20m (10 s, ~0.35 m/s) and begin stationkeeping at ~50 m for the RODK test (start 6:05pm). The 2nd manual sep burn follows at ~6:10pm (20 s; ~0.70 m/s), with two DPO-B1 thrusters. Later, ISS will return to duty attitude (LVLH/ Local Vertical Local Horizontal) at 9:05pm. [The RODK test will check out the Manual Attitude Control in Digital Mode of TMA-02M, the second Soyuz with digital controls. RODK provides automated LVLH (Local Vertical-Local Horizontal) attitude control. For the Descent Timeline, see below. Back in March, the post-undocking testing of the first digital Soyuz, TMA-01M/24S, also included the ROAK (Manual Attitude Control in Analog Mode).]

Really impressive and emotional handover speech from Mike Fossum - taped yesterday.

Special praise for ISS FD Royce Renfrew (@tungsten_flight), who led the ship that saw all science objectives completed despite the fallout from the Progress failure.

freezing cold conditions expected, no medical tents at the site if not required (if the crew is feeling fine).

edit: Thanks Pete for copying that over.
