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.

Epic intro music again.

is there a detailed timeline? undocking/deorbit/landing.

27S Descent Timeline Overview:
If everything proceeds nominally, the return to Earth of the “digital” TMA-02M spacecraft tonight will proceed along the following approximate event sequence (all times EST):
. ISS Control Handover to RS --- 5:05pm;
. Orbital (local) Sunset --- 5:27pm;
. Orbital (local) Sunrise --- 5:59:50pm;
. Undock --- 6:00pm;
. RODK Test --- 6:05pm; (RODK = Manual Attitude Control in Digital Mode)
. Deorbit Burn start (delta-V 115.2 m/sec) --- 8:32:21pm;
. Deorbit Burn complete --- 8:36:37pm (delta-V 115.2 m/s);
. Trimodule Separation (~140 km alt) --- 8:59:13pm;
. Atmospheric entry (101.6.1 km alt, with ~170 m/sec) --- 9:02:05pm;
. Entry Guidance start (81.1 km alt) --- 9:03:50pm;
. Maximum G-load (33.3 km alt) --- 9:08:50pm
. Parachute deploy command (10.8 km alt) --- 9:10:43pm;
. 27S Landing (DO1) --- 9:25pm EST; 06:25am Moscow (11/22); 8:25am local Kazakhstan; (loc. 51deg N, 67deg 10min E; northeast of the Arkalyk).

Note: Kazakhstan time = GMT+6h; = EST+11h. Moscow time = EST+9h.]

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.
