From ISS On-Orbit Status Report for 25/09/2010:

Yest posadka! (We have Landing!) Welcome back home, Tracy, Alex and Mikhail! After 177 days 1 hour 19 minutes in space

It's a mistake, it should be 176 days, not 177.

One more mistake ;)
I think 173 days 20 hours 37 minutes, not 175 days 23 hours 58 minutes docked to ISS.

"All descent operations were nominal. "

That's not what I'm being told. DM cabin pressure issues have been raised. Let's all rattle our contacts about this.

Any more info about the DM cabin pressure issue that JimO has mentioned? Was this just a rumour or a misunderstanding/mistranslation, or is there more substance to it? If so, is this about cabin pressure issues during the actual descent, or during leak checks before undocking, or something else? (I think, I have read somewhere that they had different readings from instruments in MRM-2 and Soyuz during leak check of the vestibule when they should all have been the same, but I can't find the article anymore.)

Fruit Flies Return Home from the ISS.

Soyuz TMA-18 space vehicle successfully landed this weekend returned not only 3 crew members of the International Space Station, but also two containers with fruit flies. The flies born in zero-gravity are to help the scientists to study space impact risk mitigation for the genomes.
The flies studied under Polygen experiment were chosen due to their reparation system which is similar to the human’s one. In addition, the flies propagate quickly, giving the scientists the opportunity to have much material for their work.
Fruit flies were delivered to the station by Progress in mid September, 10 maggots in each of the two containers. Then, after oviposition of the flies hatched from the maggots, the second generation of the flies appeared. Several dozens of insects returned to the Earth last Saturday, in order to let scientists verifying their capabilities in zero-g, with the further on purpose to use the results for similar evaluations of the human body.

ISS science needs continued downmass capability, plain and simple. Otherwise, certain science is delayed if not excluded.
Remembering those who made the ultimate sacrifice for our rights & freedoms, and for those injured, visible or otherwise, in that fight.

MEDIA ADVISORY: M10-141

NASA ASTRONAUT TRACY CALDWELL DYSON AVAILABLE FOR INTERVIEWS

HOUSTON -- Recently returned from a six-month stay aboard the
International Space Station, astronaut Tracy Caldwell Dyson will be
available for live satellite interviews from NASA's Johnson Space
Center in Houston between 8:15 a.m. and 10 a.m. CDT on Friday, Oct.
15.

To arrange an interview, reporters should contact producer Jeremiah
Maddix at 281-483-8631, 281-414-6995 or jeremiah.m.maddix@nasa.gov by
2 p.m., Thursday, Oct. 14. Video b-roll of Dyson's flight will air
Oct 15 from 7:45 a.m. to 8:15 a.m. on NASA Television.

Dyson and her crewmates launched aboard the Soyuz TMA-18 crew capsule
from the Baikonur Cosmodrome in Kazakhstan in April. During the
174-day mission, Dyson served as a flight engineer for Expeditions 23
and 24 and conducted three spacewalks, logging 22 hours and 49
minutes outside the station. The crew replaced a faulty cooling pump
module on the station's backbone, known as the truss. The Expedition
24 crew landed safely in central Kazakhstan on Sept. 25.

Dyson was born and raised in Arcadia, Calif. She earned a bachelor's
degree in chemistry from California State University at Fullerton and
a doctorate in chemistry from the University of California at Davis.
Dyson flew as a mission specialist on the STS-118 space shuttle
mission. On the flight, she operated Endeavor's robotic arm and
directed four spacewalks as the intravehicular crew member.

NASA TV's Live Interview Media Outlet channel will be used for the
interviews. The channel is a digital satellite C-band downlink by
uplink provider Americom. It is on satellite AMC 3, transponder 9C,
located at 87 degrees west, downlink frequency 3865.5 Mhz based on a
standard C-band, horizontal downlink polarity. FEC is 3/4, data rate
is 6.0 Mbps, symbol rate is 4.3404 Msps, transmission DVB-S, 4:2:0.

The interviews also will be broadcast live on NASA TV. For streaming
video, downlink and scheduling information, visit:

Thread temporarily unlocked to allow discussion of this fantastic, 17 minute HD Expedition 24 highlights video released today via NASA TV!

I remember we had a video like this for Expedition 23. Hopefully they're going to become a common feature for all future Expeditions! :)

NASA Tweet-Up with Doug Wheelock
http://www.space-multimedia.nl.eu.org/index.php?option=com_content&view=article&id=6561

Been watching these through the live stream.
There's a great section of images in there for the tweet-up with Doug. Highly recommended, just for that!

Also saved a ton of images from the tweet-up feed in HD.

NASA astronaut Doug Wheelock has been honoured for his contribution to the Twitterverse with a Shorty Award for the "best Real-Time Photo of the Year".

Any word yet on what actually caused it to fail?
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

Any word yet on what actually caused it to fail?

I haven't heard anything as of yet.

This is NASA's best guess so far:

Quote
The S1 Truss PM unexpectedly failed on July 31st 2010, sparking an intense period of ISS reconfiguration, and development of procedures for what ultimately turned out to be three epic EVAs to R&R the failed Pump Module.

According to the SSPCB notes, the failure investigation team are looking at “whether ammonia could have leaked into the pump motor stator area (sealed and filled with N2 normally)”, and will be determining “whether the ammonia flow was interrupted in the ‘secondary’ flow areas in the pump (used to lubricate and cool the bearings and friction surfaces)”.

The notes also state that in late 2008, it was observed that the overall pump pressure was reduced, and that delta pressure (PSI-D) across the pump was showing a variance from nominal values. Current spikes were also noted during this period.

The SSPCB were informed that the delta pressure and current draw data were not part of standard analysis in the past, but that they will be reviewed regularly in future as they may be useful for identifying possible pump degradation. It was also stated that 370mS (milliseconds) prior to the 54A current spike that occurred during the July 31st failure, the current draw from the pump went to zero Amps.

Being that the pump has only been on the ground for a couple of months, I would guess that it is still in the process of failure investigation.  That's not the area that I am in, but I'm sure that when they have finished their testing, the information will be disseminated to the correct panels and everybody will find out in due time.  Just takes a while  :)
