They should try growing tomatoes (if they haven't already)!

Looks like they will be.

Continuing OGS (Oxygen Generator System) troubleshooting, FE-5 Williams & Nicole Stott temporarily deactivated and removed the ALTEA (Anomalous Long Term Effects on Astronauts) dosimeter unit to allow OGS rack access, then removed the failed water ORU (Orbit Replaceable Unit) and replaced it with a refurbished unit. [Additional activities included purging with the HOPA (Hydrogen Sensor ORU Purge Adapter), reconnecting the OGS H2 sensor, activating OGS, rotating the rack down for a first visual leak check, then temporarily closing out the track for a 3-hr dwell, rotating it down for a second leak check and finally replacing the rack rear panel, rotating the rack up and reinstalling the ALTEA.]

IWS Thruster Test: This morning at 1:23am EST, a ground-controlled SM thruster firing test (4 tests with 2 pulses each) was conducted for IWIS (Internal Wireless Instrumentation System) structural dynamics data taking, with ISS attitude moded to free drift at 1:20am-1:23am. Control authority was returned from RS Motion Control to US Momentum Management at 2:15am.

To be prepared for an emergency evacuation and return to Earth in winter time, Romanenko & Suraev relocated six standard Russian TZK-14 Thermal Protection Jackets from FGB, SM & Progress stowage to the two Soyuz spacecraft TMA-15/19S & TMA-16/20S, three jackets for each. [These warm coats, always ready for an emergency return in winter, would be required for the landing in Russia or Kazakhstan this time of year.]

SSRMS Operations: Starting at ~10:00am EST, the Space Station Remote Manipulator was maneuvered remotely from the ground inchworm-like through a double walk-off, first from the Node-2 PDGF (Power & Data Grapple Fixture) to the MBS (Mobile Base System) PDGF-2, then, at ~12:50pm-7:00pm, to MBS PDGF-1. Some diagnostic tests were also performed, in order to satisfy ULF3 pre-launch checkout requirements.

Node 1's port CBM hatch leading into PMA-3 has been opened!

From ISS Daily Report 3 Nov 2009:

Quote
FE-4 Thirsk began the day by terminating the overnight leak check of the PMA-3 (Pressurized Mating Adapter 3), in preparation for PMA ingress. [The VAJ/ISA (Vacuum Access Jumper/Internal Sampling Adapter) hose assembly was left in place in preparation for PMA-3 depress.]

Afterwards, in preparation for Node-3 “Tranquility” arrival on STS-130 in February, Thirsk & FE-5 Williams –

    * Opened the Node-1 port hatch to PMA-3 and removed the hatch center disk cover, two CPAs (Controller Panel Assemblies) and the PMA target assembly,
    * Removed several closeout panels to gain access to the bulkhead feedthroughs, then
    * Spent several hours replacing five electrical feedthrough cables with five fluid feedthrough umbilicals.


Also in Node-1, Nicole Stott subsequently spent ~1h15m removing the existing NPRV (Negative Pressure Relieve Valve) at the Port and installing an IMV (Intermodule Ventilation) valve in its place, preparatory to Node-3 midbay modifications. [The valve was installed already now while access to the extravehicular side of the bulkhead is available to ensure that the NPRV could be successfully removed from the bulkhead. Power, data and RMO (Remote Manual Override) connections to the valve will be made later, during/after ULF3.]

Afterwards, Jeff Williams closed the Node-1 port hatch to help minimize the humidity levels in the PMA. [Will be opened again tomorrow to continue work. To prevent condensation in PMA-3, PMA activities can only be performed during certain Beta angles since the module’s heaters were not connected on Flight 17A. The acceptable Beta window opened on 10/29 and closes on 11/9.]

SSRMS Operations: From ~3:15pm-5:15pm EST, ground operators will translate the MT (Mobile Transporter) railcart on the truss from WS5 (Workstation 5) to WS3, to satisfy another ULF3 pre-launch checkout requirements as well as put the Robotics systems into a good configuration to allow JAXA to perform their upcoming ICS (Inter-Satellite Communication System) checkout.

ISS Power Outage Event: Yesterday morning at 12:54am EST, MBSU1 (Main Bus Switching Unit 1) experienced an unexpected power loss due to a POR (Power On Reset), the first on-orbit POR on any MBSU hardware. MBSU1 was recovered almost immediately, but it took time to assess deactivated systems and start them up again. Systems were down for about 3 hrs. Engineering teams are reviewing the anomaly but currently believe the POR was a random event and that MBSU1 is healthy and not susceptible to further PORs. MBSU1 controls half of station systems, and there were some impacts to yesterday operations, mostly science activities. ISS is completely recovered.

UPA Anomaly: Should the Urine Processor Assembly remain down for longer than expected, the unprocessed urine will accumulate, requiring special provisions for collecting, containing & stowing, including during ULF3-docked period. Replanning is underway at MCC-Houston and TsUP-Moscow for using Russian EDV containers (58 total, 9 US, 49 RS), Rodnik tanks and CWCs. Current efforts include discussions with Moscow to extend the normal EDV lifetime of 90 days to 120 days.

Thanks rdale for the post.

I wonder if any science/experiments were lost as a result? I'm sure most could be re-done, but I'm wondering about the ones that can't.

This is sounding alot liek the latest sci-fi episodes: contigencies for power outage on long-duration missions. Redundant battery back-ups on a separate grid would seem obvious in those cases.

UPA Status Update: This morning, the DA (Distillation Assembly) was successfully drained completely into the WSTA (Waste Storage Tank Assembly), and drydown is proceeding as planned. This is a very good sign since it shows that the blockage is clear, did not re-clog and the pump is operational. For follow-up troubleshooting & planning work in case of UPA unavailability, five specialist teams have been formed at MCC-H.

MBSU1 POR Status Update: The POR (Power-On Reset) of the Main Bus Switching Unit 1 on 11/3, which caused a brief power outage, continues to be investigated for its root cause. All station system are fully re-configured back to normal, and nothing in the data shows that there are any residual effects of POR. It looks like a random event, and the incidence showed that critical Bus Loss Procedures worked as expected.

CO2 Update: The Russian Vozdukh continues to be off as planned for U.S. CDRA (Carbon Dioxide Removal Assembly) testing. ppCO2 (CO2 partial pressure) this morning was low, at 3.14 mmHg.

ICS Testing: Yesterday, JAXA started the planned checkout of the Inter-Satellite Communication System. A test command was sent successfully, established forward and return links plus file transfer with ICS. “Everything is operating nominally for ICS.”

Rumors of a RED Late Conjunction. Checking.
Being noted by PAO in today's commentary...not a lot of confidence in data...closest approach in 11 hours, 45 minutes...called up on A/G an hour ago...

(A/G replayed; estimate in the call was for the conjunction at about 03:48 GMT tomorrow.)

The callup is right at the beginning of http://issaudio.project10.net/iss_20091106-100000-003.wav

One more datapoint coming on this conjunction, which occurs tonight at 0348Z. They'll have more info in the evening DPC at 1905Z (2:05pm EST)

Good work guys! So it's not like the previous incident - yet? They need to work it some more to see if it's going to be a RED and thus the need to safe haven the crew?

Certainly too late for a reboost if required?

From what I'm hearing, correct. Since it's in the middle of their sleep cycle, I imagine they'll want to be pretty certain before putting them in the Soyuz. There was no mention of the specific time for the next pass, but the DPC is just 3 hours away so they'll probably keep quiet until that point.

Noted in commentary during today's ISS hour that there's a possible conjunction at approx. 03:48 GMT tomorrow (about 11 1/2 hours from now).
