BBC News: "Beer microbes live 553 days outside ISS".
www.bbc.co.uk/news/science-environment-11039206

This actually made the BBC 6 O'clock & 10 O'clock News tonight. They showed the STS-122 launch, and talked about the experiment installation while showing STS-130's EVAs. ::)

Sorry for the absence of ISS reports lately - I've been away.

From ISS On-Orbit Status Report for 23/08/2010:

In an attempt to regain command capability to access science data of the JAXA MAXI (Monitor of All-sky X-ray Images) payload, MCC-Houston remotely transited the primary C&C (Command & Control) MDM computer to the standby C&C. In support of the transition, FE-4 Doug Wheelock then reconnected all powered PCS (Portable Computer System) laptops to the new prime, C&C-2. [C&C-1 is now backup, and C&C-3 is on standby. The MAXI experiment is attached to the JEF (Japanese Exposed Facility) on the exterior of the station.]

From ISS On-Orbit Status Report for 24/08/2010:

FE-2 Tracy Caldwell-Dyson retrieved the MELFI-1 trays, which had been put out for drying after the recent power-downs, and inserted them into MELFI-3's Dewar 1.

In preparation for the next Progress M-07M/39P on arrival 10/09, CDR Alexander Skvortsov & FE-3 Mikhail Kornienko, with TsUP support, conducted the standard 30 minute intermodular space-to-space (wireless) test of the TORU teleoperated rendezvous & docking system, i.e., between the TORU control station in the SM and Progress M-06M/38P, docked at SM Aft. Progress DPO (Approach & Attitude Control) thrusters were not commanded. [TORU is the manually teleoperated backup approach and docking system for the automated Progress ships. It will be on "hot standby" during the upcoming arrival of 39P.]

With Alexander, Mikhail & Tracy due to depart on Soyuz TMA-18/22S on 24/09, Alexander & Mikhail (of Expedition 24) spent several hours with FE-5 Fyodor Yurchikhin (of Expedition 25) on handover activities, to get Fyodor up to date with RS (Russian Segment) tasks and issues.

TVIS Update:
TVIS (Treadmill with Vibration Isolation System) is currently No-Go due to some off-nominal noise during operation, and one of the slats appears to be partially buckled. A troubleshooting procedure was developed. This activity has some urgency since Alexander & Mikhail are within the thirty day deadline of required return exercise protocol. They are currently approved for using the T2 COLBERT treadmill. (Note: TVIS is located in the SM, and TVIS ops. are currently under RS control, however maintenance remains the responsibility of US specialists.)

From ISS On-Orbit Status Report for 25/08/2010:

With all remaining propellants in Progress M-06M/38P transferred, TsUP/Moscow today performed the standard vacuum purging of the Progress fuel (ZUG) and oxidizer (ZUO) lines, venting propellant residuals in the plumbing between Progress & SM into space, with prior attitude control handover to the Russian MCS (Motion Control System). All events were nominal.
Earlier, FE-4 Doug Wheelock had closed the protective shutters of the Lab, JPM & Cupola science windows. Also, to protect the T2 treadmill during the line purging/venting, the orange-colored snubber alignment guides (4) were installed by Wheels before the US-to-RS handover and removed again by FE-2 Tracy Caldwell-Dyson after the RS-to-US handover.

TVIS Update:
TVIS (Treadmill with Vibration Isolation System) is currently No-Go due to some off-nominal noise during operation, and one of the slats appears to be partially buckled. A troubleshooting procedure was developed and uplinked for comment, to be implemented by CDR Alexander Skvortsov & FE-5 Fyodor Yurchikhin tomorrow. The procedure includes involves removal of the raised belt slat along with the two slats surrounding it and replacement of all three with spares if they are damaged. Afterwards, both a manned and unmanned ACO (Activation & Checkout) run with video/audio capture complete the procedure.

ISS ship-tracker operating alongside Norwegian satellite

26 August 2010
Nearing the end of its third month of continuous operation, the International Space Stations ship-tracking experiment has experienced a marked increase in data quality. Now it operates along with a dedicated satellite carrying the same receiver.

From ISS On-Orbit Status Report for 26/08/2010:

CDR Alexander Skvortsov & FE-5 Fyodor Yurchikhin spent several hours on a major IFM (Inflight Maintenance) on the TVIS (Treadmill with Vibration Isolation System) treadmill in the SM, trying to repair the running belt which had created off-nominal noise due to a buckled belt slat. TVIS troubleshooting is expected to continue tomorrow (see note at bottom).

FE-3 Mikhail Kornienko meanwhile replaced the TVIS Control Panel in the SM, first powering it off with the circuit breaker, waiting for about an hour (to cool down), then uninstalling the current control panel (#1001), taping & stowing it, and installing the new control panel (#1002) instead. Both panels were photo documented.

Additionally, Mikhail used pressurized O2 from Progress M-06M/38P O2 stores for another refresh of the ISS cabin for about an hour. [The Elektron O2 generator is currently off.]

TVIS Update:
After the Russian crewmembers this morning obtained video of the original anomaly and also removed the raised belt slat, they found a small bolt under the slat – the cause of the buckling and noise. The original troubleshooting plan was to remove 3 slats and weld nuts and then to conduct an overall inspection of the tread belt, chassis, and chassis components. Now that the root cause of the noise is known, ground teams are meeting to optimize the remaining work that must be performed. TVIS troubleshooting is expected to continue tomorrow.

Thanks for posting the latest. Been slacking off on keeping up with these...

(Thinking out loud...) Something in the back of my mind is recalling an issue with TVIS a few months back, and they noted that something was missing and never found. Perhaps it was this missing bolt? Time will tell, as they need to know where the bolt came from. If I have time tomorrow I might browse back and see if I can find it.

From ISS On-Orbit Status Report for 27/08/2010:

CDR Alexander Skvortsov, with FE-3 Mikhail Kornienko assisting for the checkout, spent several more hours on Part 2 of the IFM (Inflight Maintenance) on the TVIS (Treadmill with Vibration Isolation System) in the SM, repairing the running belt which had a buckled belt slat due to a loose screw found under it, stemming probably from a TVIS drum. [The new situation required the crew to (1) inspect both drums, (2) check the tread belt fabric for damage, (3) verify weld nut alignment, (4) re-torque the belt slat screws & apply new witness marks to them (which would indicate, over time, slight rotational displacements of the screws), and (5) inspect the roller bearings for possible damage by the screw. An unmanned & manned ACO (Activation & Checkout) run was to wrap up the troubleshooting.]

Activities conducted by FE-6 Shannon Walker today included:
Equipping the Node 2 Port stowage hatch handle with the label
  "Use Manual Override".
Performing a data collection session on the CubeLab and transferring
  the data to laptop.
Looking for missing Node 2 CQ (Crew Quarters) rack brackets.

Japan to stay in ISS project past 2016.

The Strategic Headquarters for Space Policy, headed by Prime Minister Naoto Kan, has decided Japan will continue to participate in the International Space Station (ISS) project through 2016 and beyond.

The government will officially communicate its decision, made Aug. 27, to other participating countries in the near future.

The United States has proposed that the ISS -- whose future from 2016 and beyond had been undecided -- remain in operation until at least 2020. However, Japan's continued participation in the project was attacked in last autumn's cost-cutting committee deliberations, with critics pointing out that the ISS was costing Japanese tax payers some 110 million yen a day.

From ISS On-Orbit Status Report for 29/08/2010:

Today at 8:09 AM EDT/12:09 PM GMT, the ISS (specifically the FGB) completed 67,500 orbits of the Earth, having covered a distance of 2.91 billion km (1.82 billion st.miles) in 4300 days, or about 5 times the Hohmann travel distance to Mars. [The 19,300 kg/42,600 lbs FGB was launched on a Russian/Khrunichev Proton from Baikonur almost 12 years ago, on 20/11/1998, as the first element of the multi-national space station.]

Upon TsUP GO FE-3 Mikhail Kornienko was to use pressurized O2 from Progress M-06M/38P O2 stores for another refresh of the ISS cabin for about an hour. [The Elektron O2 generator is currently off.]

From ISS On-Orbit Status Report for 30/08/2010:

Underway: Week 13 of Increment 24. Big Science this week!

FE-3 Mikhail Kornienko spent several hours on preparing Progress M-06M/38P for its departure tomorrow morning (~11:22 AM GMT). Specifically, the usual close-out steps included:
• Installing the docking mechanism (StM, Stykovochnovo mekhanizma)
  between Progress and the SM Aft port.
• Uninstalling & removing the LKT local temperature sensor commutator
  (TA251MB) of the BITS2-12 onboard measurement telemetry, along
  with its ROM (Read Only Memory) unit (TA765B) for re-use.
• Scavenging (removing) an SD1-7 double-light fixture from the
  Progress, stowing it with spares & updating the IMS.
• Activating the spacecraft's electronics and taking out the
  ventilation/heating air duct.
• Closing the hatches on TsUP Go (~3:30 PM GMT).
• Removing the QD screw clamps (BZV) of the docking & internal transfer mechanism
  (SSVP) which rigidized the joint [during clamp removal and leak checking, Russian
  thrusters were inhibited from 3:00 PM to 7:40 PM GMT due to load constraints].
• Starting the standard one-hour leak checking of the SU docking
  vestibule and fuel/oxidizer transfer line interface between Progress and the SM.
• Downlinking Mikhail's formal report on loading completion and the video
  depicting the close-out activities, for review by ground specialists.
