4B array now fully latched, GO for relocation!
 
Undocking occurred at 3:13 PM EDT, much to the surprise of U.S. flight controllers as Russian controllers initiated separation as soon as the green light was given.

Undocking has occurred - the Russians did it early at 1:13 PM CDT/7:13 PM GMT!
 
From ISS On-Orbit Status Report for 27/06/2010:

Soyuz TMA-19/23S relocation was completed without incident, although delayed by 75 minutes due to a stall of the 4B BGA (Beta Gimbal Assembly) motor as it was moving the 4B solar array to its latched position. After system recovery by ground control, it took the array some time to reach its final position, delaying the undocking from 5:58 PM GMT to ~7:13 PM GMT. The relocation freed up the SM Aft port for the arrival of Progress M-06M/38P on 02/07 (Aft port being more advantageous for using Progress for reboost/debris avoidance maneuvers).

Before hatch closing & leak checking (~1:40 PM GMT), Yurchikhin configured and checked out communications from Soyuz TMA-19, while the ground deactivated the LKT (Local Temperature Sensor) on Soyuz and the SKV-1 air conditioner on ISS.

RS (Russian Segment) thrusters were disabled at ~1:45 AM GMT for the FGB QD (Quick Disconnect, BZV) screw clamps removal.

In TMA-19, after hatch closure Fyodor, Doug & Shannon removed their cabin suits and donned biomedical belts & Sokol pressure suits, then performed Soyuz checkout operations.

For the relocation, ISS attitude control authority was handed over to RS MCS (Motion Control System) at 5:20 PM.

After a brief ride in their crew return vehicle, FE-5 Yurchikhin, FE-4 Wheelock & FE-6 Walker docked at the new MRM-1 at 7:38PM GMT, completing the spacecraft's relocation in about 25 minutes. [After undocking, Soyuz CDR Yurchikhin backed away from the station 25-30 m at ~0.12 m/s, then translated the spacecraft below the station, slewing sidewise through 90° along the ISS toward the aft end before rotating ("indexing") the Soyuz around its longitudinal axis to align its periscope with the docking target on MRM-1, spending a short time in station-keeping mode. Final approach began at ~7:34 PM GMT. The relocation was conducted with ISS entirely in "earth-fixed" LVLH (Local Vertical/Local Horizontal) attitude, without the usual Inertial snap/hold.]

After TMA-19 separation from the SM Aft port, CDR Skvortsov took photographs of the spacecraft's docking assembly for subsequent inspection by ground specialists.

After Soyuz re-docking, Skvortsov closed the Soyuz KVD/PEV (Pressure Equalization Valve) and later switched it to electric mode.

Meanwhile, the Soyuz crew completed the standard leak checking between the Soyuz Descent Module (SA) & Orbital Module (BO), then opened the internal hatch and started drying of two Sokol suits & their gloves.

At ~8:15 PM GMT, the crew started transfer hatch & MRM-1 vestibule leak checks, then opened hatches at ~9:30 PM, installed QD (Quick Disconnect) clamps (~9:50 PM) and started airing out the third Sokol.

RS thrusters were again temporarily inhibited for the leak checking, hatch opening and post-docking clamp installation. TMA-19 deactivation then began, completing LiOH (Lithium Hydroxide) cartridge replacement (for CO2 removal) and transition of the TMA-19 spacecraft back to ISS/combined power.

ISS attitude control later returned to US Momentum Management after the solar arrays had been positioned.

Are there fresh pictures of the MRM-1's interior, free of luggage?

I'm afraid not - NASA haven't released any yet. :(

However, I do have this image of MRM-1's interior during preflight processing.

[Note: Kazakhstan time = GMT + 6 hours; = EST + 11 hours. Moscow DMT = EST + 8 hours.]

What the Soyuz TMA-19 crew will experience during their reentry/descent this morning:
  • For the reentry, Doug, Shannon & Fyodor will wear the Russian Kentavr anti-G suit under their Sokol suits. [The Kentavr garment is a protective anti-G suit ensemble to facilitate the return of a long-duration crewmember into Earth's gravity. Consisting of shorts, gaiters, underpants, jersey and socks, it acts as countermeasure for circulatory disturbance, prevents crewmember from overloading during descent and increases orthostatic tolerance during post-flight adaptation. Russian crewmembers are also advised to ingest fluid electrolyte additives, viz., three sodium chloride tablets during breakfast and after the midday meal, each time with 300 ml of fluid, and two pills during the meal aboard Soyuz before deorbit.]
  • Before descent:
    Special attention will be paid to the need for careful donning of the medical belt with sensors and securing tight contact between sensors and body.
    During preparation for descent, before atmosphere reentry, crewmembers settle down comfortably in the Kazbek couches, fasten the belts, securing tight contact between body and the seat liner in the couch.
  • During de-orbit:
    o Dust particles starting to sink in the Descent Module (SA) cabin is the first indication of atmosphere reentry and beginning of G-load effect. From that time on, special attention is required as the loads increase rapidly.
    o Under G-load effects during atmosphere reentry the crew expects the following experience:
    Sensation of G-load pressure on the body, burden in the body, labored breathing and speech. These are normal sensations, and the advice is to "take them coolly". In case of the feeling of a lump in the throat, this is no cause to "be nervous". This is frequent and should not be fought. Best is to "try not to swallow and talk at this moment". Crew should check vision and, if any disturbances occur, create additional tension of abdominal pressure and leg muscles (strain + abdomen by pulling in), in addition to the Kentavr anti-G suit.
    o During deployment of pilot parachute (0.62 & 4.5 square meters), drogue chute (16 sq.m.) and main (518 sq.m.) chutes the impact accelerations will be perceived as a "strong snatch". No reason to become concerned about this but one should be prepared that during the parachutes deployment and change ("rehook") of prime parachute to symmetrical suspension, swinging and spinning motion of the SA occurs, which involves vestibular (middle ear) irritations.
  • It is important to tighten restrain system to fasten pelvis and pectoral arch.
    Vestibular irritation can occur in the form of different referred sensations such as vertigo, hyperhidrosis, postural illusions, general discomfort and nausea. To prevent vestibular irritation the crew should "limit head movement and eyes movement", as well as fix their sight on motionless objects.
  • Just before the landing (softened by six small rocket engines behind the heat shield):
    Crew will be prepared for the vehicle impact with the ground, with their bodies fixed along the surface of the seat liner in advance. "Special attention should be paid to arm fixation to avoid the elbow and hand squat" (instruction). Landing speed: ~9.9 m/sec.
  • After landing:
    Crew should not get up quickly from their seats to leave the SA. They were advised to stay in the couch for several minutes and only then stand up. In doing that, they should limit head and eyes movement and avoid excessive motions, proceeding slowly. Their body should not take up earth gravity in the upright position too quickly.

Fiodor Yurchikhin, Shannon Walker and Douglas Wheelock Returned to the Earth

:: 26.11.2010

Soyuz TMA-19 descent capsule with the crew – commander Fiodor Yurchikhin and NASA astronauts Shannon Walker and Douglas Wheelock - this morning landed successfully to the North away from Kazakh’s Arkalyk at 7:46 (04:46 GMT).

The Soyuz departed from the International Space Station at 4.23 MSK.
Health status of the crew is fine. All descent operations were nominal.
Yurchikhin, Walker and Wheelock spent about 5.5 months aboard the ISS carrying out station’s maintenance and science.
Fiodor Yurchikhin made two space walks.

After the departure of Soyuz TMA-19, three-person crew – Alexander Kaleri, Oleg Skripochka and ISS-26 commander Scott Kelly – with continue operations in the ISS, until mid-December, when Catherine Coleman, Paolo Nespoli and Dmitri Kondratyev arrive to round out the outpost's Expedition 26 crew.

NASA: "Soyuz Landing Caps Space Station's First Decade of Expeditions".

Expedition 25 Commander Doug Wheelock and Flight Engineers Shannon Walker and Fyodor Yurchikhin safely landed their Soyuz spacecraft on the Kazakhstan steppe Thursday, wrapping up a five-month stay aboard the International Space Station.

Russian cosmonaut Yurchikhin, the Soyuz commander, was at the controls of the spacecraft as it undocked at 8:23 p.m. EST from the station's Rassvet module. The trio landed at 11:46 p.m. (10:46 a.m. on Nov. 26 local time) at a site northeast of the town of Arkalyk.

Working in frigid temperatures, Russian recovery teams were on hand to help the crew exit the Soyuz vehicle and re-adjust to gravity. Yurchikhin will return to the Gagarin Cosmonaut Training Center in Star City, outside of Moscow, while Wheelock and Walker will fly directly home to Houston.

The trio launched aboard the Soyuz TMA-19 spacecraft from the Baikonur Cosmodrome in Kazakhstan on June 15. As members of the Expedition 24 and 25 crews, they spent 163 days in space, 161 of them aboard the station, and celebrated the 10th anniversary of continuous human life, work and research by international crews aboard the station on Nov. 2.

During their mission, the Expedition 24 and 25 crew members worked on more than 120 microgravity experiments in human research; biology and biotechnology; physical and materials sciences; technology development; and Earth and space sciences.

The astronauts also responded to an emergency shutdown of half of the station's external cooling system and supported three unplanned spacewalks by Wheelock and Expedition 24 Flight Engineer Tracy Caldwell Dyson to replace the faulty pump module that caused the shutdown. Their efforts restored the station's critical cooling system to full function.

Yurchikhin has logged 371 total days in space, Wheelock 178 days and Walker 163 days.

The station is occupied by Expedition 26 Commander Scott Kelly and Flight Engineers Alexander Kaleri and Oleg Skripochka of the Russian Federal Space Agency. A new trio of Expedition 26 flight engineers, NASA astronaut Catherine Coleman, Russian cosmonaut Dmitry Kondratyev and Paolo Nespoli of the European Space Agency, will launch from the Baikonur Cosmodrome on Dec. 15. They will dock with the station and join its crew on Dec. 17.
