Houston called up the news to the crew that threat is gone and they can go back to sleep.  The crew also spoke with Moscow; all the contingency procedures are canceled.
In case anyone is interested in the space-to-ground for that, it's in this sound file:

I think that's a high-five all around...

Excellent that all is OK and excellent coverage of what can now be called a non-event.

After last night’s station configuration changes for a possible decrewing due to the threat of an overnight collision with Object 80908, which included USOS (US Segment) hatch closures, FE-5 Williams reconfigured the ITCS (Internal Thermal Control) rack jumpers in the US Lab to nominal. [The contingency preparations were essentially those normally used for Soyuz relocation during three-crewmember station occupancy. Jeff today jumpered the racks in the forward endcone and at the LAB1P3 location from LTL (Low Temperature Loop) back to the Lab MTL (Medium Temperature Loop), i.e., single loop configuration. During yesterday’s ITCS preparation for the decrewing, the LAB1D1 MTL return QD (quick disconnect) leaked when Jeff tried to demate it (less than 1% was lost from the accumulator.). This happened again during several subsequent attempts. The LAB1D1 rack was left unconnected to LTL, the usual uncrewed precaution. The Lab endcone and P3 racks were properly connected to LTL. Engineers are planning forward action for the QD.]

After several days of (successful) performance testing of the U.S. CDRA (Carbon Dioxide Removal Assembly), FE-1 Suraev re-activated the Vozdukh CO2 scrubber of the Russian SOA Atmosphere Revitalization Subsystem, checking BVK1,2 valve group operation.

Conjunction Update: Preparations for a possible collision with Object 80980 proved unnecessary (and ran into a snag with an ITCS coolant connector, see above). By ~7:00pm EST last night, NASA FCT (Flight Control Team) had received two updates, from two different sensor sources, which were consistent with each other and with previous tracking such that the PC (Probability of Collision) had dropped below the actionable threshold. FTC stood down from planning to put the crew in the Soyuz vehicles.

I checked in with Dr Kelso (CelesTrak) and he said that designations > 80000 are for an "analyst satellite" which is used when the origin of the object is unknown or uncertain.

COLBERT update:

The crew was given the Go for nominal use of the new T2/COLBERT treadmill. [Belt speed during runs should be kept between 3 & 10mph, and target load should not exceed 75% of the runner’s body weight. The handrail must be installed during exercise and removed when T2 is not in use.]  (ISS On-Orbit Status 11/09/09)

UPA Failure Update: The Urine Processor Assembly failed to spin up on the last two consecutive tries yesterday due to high current events on the DA (Distillation Assembly) drive motor. The DA is considered failed; however, ground teams are still assessing the data from yesterday’s startup attempt. Failure Investigation and Forward Plan will be scheduled later this week to discuss the plans for the DA.

Damn...sounds like a bearing failure, or something 'gummed up'.

UPA Update: The U.S. Urine Processor Assembly is now officially inoperable. Teams are working the issues of water management, urine management and stowage in order to accommodate for UPA inoperability. With UPA being down, the problem can be handled through ULF3 and with help from the Russian partners an alternate way is being developed through 20A. This is going to create an additional stowage problem on the ISS, and all partners will pitch in in order to find a way to accommodate the urine stowage requirements aboard the station. As per today’s IMMT (ISS Mission Management Team) meeting the ISS is Go for STS-129/ULF3 launch on Monday.

How to decide how many empty containers should be sent to orbit? For dry stuff it can be reasonably simple since it's just bags, and in extremis stuff doesn't need a container.
But for fluids you always need containers, and the amount is much more difficult to pin down. You got the strict separations of various kinds of fluids for which containers are not interchangeable. And the ratio between which cannot be determinded beforehand.
You got some variable amount of water from Shuttle, depending on how the mission goes.
You got varying levels of consumption for individual crew.
and you got equipment failure like in the present case that suddenly change container requirements for waste.

I wonder if they're planning on sending spare parts for the UPA (IIRC, those can be delivered as middeck cargo, right?), and if so, in which flight. Probably it's already too late for 129?

At today's L-2 press conference it was stated that the failed UPA parts would be brought down  on STS-129 and replacement parts would go up no later than STS-130 in February.

The DA will go up on STS-130 in February (there is a chance this could move up to January - being thought about), it would not be ready for this week's launch.

As far as how many containers for fluids goes up, there is only so many in the inventory.  So we try to maximize as many as we can fit pretty much.

Thanks for that, and to rdale for his initial update post.
