NASASpaceFlight: "ISS partners asked to assess Station extension to 2025 – potentially 2028".

:speakcool: :woohoo:

---------- Post added at 09:04 PM ---------- Previous post was at 06:22 PM ----------

From ISS On-Orbit Status Report for 08/07/2010:

FE-2 Tracy Caldwell-Dyson joined FE-4 Doug Wheelock in Node 3 for Part 2 of CDRA (Carbon Dioxide Removal Assembly) maintenance, establishing redundancy for the system by installing a second desiccant/sorbent Bed (#201). [After yesterday's bed installation & replacement of most component groups in CDRA in front of the new bed, Wheels & Tracy today finished up with component restoration, then installed CDRA in AR-1 (Atmosphere Revitalization rack-1) and mated all utilities of the rack. For access to the worksite, the WHC (Waste & Hygiene Compartment) Kabin had to be removed (later restored) and the AR-1 rotated down temporarily.]

FE-6 Shannon Walker had ~1 hour set aside to continue troubleshooting on the WHC, today (Part 2) going through newly uplinked procedures to try to isolate the source of recent WHC failure to either the Pump Separator or its Control Unit by demating the power connection to these ORUs (Orbital Replacement Units) and running a functionality test. [Yesterday's troubleshooting by reconfiguring the system after the scheduled replacement of the piping was unsuccessful; the control panel turned itself off twice during start-up. The crew is currently continuing to use the Russian ASU toilet facility in the SM.]

FE-5 Fyodor Yurchikhin used pressurized O2 (Oxygen) from Progress M-06M/38P Oxygen stores for another refresh of the ISS cabin for about an hour (see OGA note below).

US EVA Planning Change:
There will be only one US EVA during Increment 24. Specifics to be baselined later this week.

Progress M-06M/38P Rodnik Tank Failure:
Urine transfer from EDV containers to the empty BV1 Rodnik storage tank of 38P on 06/07 was aborted when a pre-transfer tank bladder compression indicated a leak from BV1 (air). Moscow will postpone urine transfer to BV1 until right before 38P undocking.

TORU Testing Update:
Yesterday's two-part TORU testing by Skvortsov & Yurchikhin was not completed due to bad radio/telemetry connection from TsUP-Moscow to the RGS (Russian Ground Site) during Part 1 (without Klest).

OGA Failure:
The US OGA (Oxygen Generator Assembly) continues to be down, having failed on 05/07 due to a high voltage in two cells in the H2 (Hydrogen) dome. A forward plan to determine the root cause is in work as teams work down a fault tree. O2 margins are good until tomorrow provided Elektron remains operational (currently running on 32 Amp). Progress O2 could also be used. There is one spare H2 dome on board and none on the ground.

Roscosmos PAO: "Roscosmos: Chinese Space Vehicles Could Fly to the ISS".

Chinese space vehicles meet all safety requirements to provide redundancy for Soyuzes and Progresses during missions to the International Space Station, Anatoly Perminov, Roscosmos Head told RIA Novosti.

According to him, the Chinese can support the program after shuttle retirement in 2011, when Russia remains the only country to maintain ISS crew rotation.

"This is rather tough, so Russia is interested in backup Chinese vehicles", Perminov said.

Five ISS partners have not received any answer from China for the proposal to join the program.
"Administrator of the Chinese Space Administration has quit, and the new one has not been appointed yet. So, the issue is still open", Perminov concluded.

NASA: "NASA And Partners Assign Crews For Upcoming Space Station Missions".

---------- Post added 9th Jul 2010 at 10:08 PM ---------- Previous post was 8th Jul 2010 at 10:18 PM ----------

From ISS On-Orbit Status Report for 09/07/2010:

Working in the Lab, FE-6 Shannon Walker prepared location Starboard 1 (LAB1S1) for the temporary installation of the Node 3 ARS Rack by installing a K-BAR (Knee-Brace Assembly Replacement) Capture Fitting & Pivot Fitting. [The ARS "musical chairs" relocation is scheduled to start early next week. Sabatier installation/activation will eventually require an active ARS rack in Node 3, but the Lab ARS Rack, currently installed in Node 3 without umbilicals mated, cannot be activated in Node 3. So the Node 3 & Lab ARS racks must be swapped back to their original locations. Next week's task moves the Node 3 ARS from Lab Deck 6 (LAB1D6) to Lab Starboard 1 as a temporary location, for which Shannon prepared the K-BAR today. The second rack, i.e. the Lab ARS rack, will then be moved from Node 3 Aft 4 (NOD3A4) to Lab Deck 6, and the Node 3 ARS rack will lastly be transferred from Lab Starboard 1 to its final location at Node 3 Aft 4.]

After Shannon first connected the UOP (Utility Outlet Panel) DCP (Display & Control Panel) power bypass cable at the Cupola RWS (Robotic Workstation) and video cameras were configured, Shannon & FE-2 Tracy Caldwell-Dyson "walked off" the SSRMS (Space Station Remote Manipulator System) from the Lab PDGF (Power & Data Grapple Fixture) to the MBS (Mobile Base System) PDGF-3. [The MBS MT (Mobile Transporter) was translated yesterday by ground controllers from WS-4 (Worksite 4) to WS-6 in preparation for the upcoming RPCM (Remote Power Controller Module) swap with the SPDM (Special Purpose Dexterous Manipulator). The translation was delayed by about 1 hour due to a communication problem during SPDM powerdown, but functionality was restored by cycling RWS power. Otherwise, system performance was nominal.]

TORU Testing Update:
The repeat of the two-part TORU testing by CDR Alexander Skvortsov & FE-5 Fyodor Yurchikhin originally scheduled for today was cancelled.

WHC Update:
After the failure of the WHC (Waste & Hygiene Compartment) toilet facility was traced to the MNR-NS pump/separator, the crew replaced the unit with a Russian spare from FGB stowage which recovered the system. The WHC is now working nominally and GO for use. According to the near-term plan, the WHC remains configured for internal EDV-U use for waste collection. Its re-integration with the UPA (Urine Processor Assembly) will require additional investigation. [The only US spare unit on board is currently "lost" and cannot be found.]

CDRA Update:
The crew completed the reinstallation of the CDRA (Carbon Dioxide Removal Assembly) component groups and re-mounted CDRA in the AR1 (Atmosphere Revitalization 1) rack. Due to limited time, CDRA utilities were not connected up to make it operational. That procedure will be completed next week. The rack relocations that will result in two operational CDRAs have been deferred to later in the month.

From ISS On-Orbit Status Report for 11/07/2010:

Conjunction Advisory:
Flight controllers had a late notification of a new conjunction (Object 33977/COSMOS 2251 debris, from the Feb. 2009 collision with IRIDIUM 33). TCA (Time of Closest Approach) is tomorrow (12/07) at 7:12 AM GMT. This conjunction is currently a low risk. No action required at this time.

Solar Eclipse:
A total solar eclipse will occur today over the South Pacific Ocean. The ISS will pass through the penumbral shadow on two orbits resulting in a partial solar eclipse for the crew from 6:19 PM to 6:41 PM GMT and again from 8:06 PM to 8:15 PM GMT.

Today is the 10th anniversary of the launch of the Service Module "Zvezda" (launched on 12/07/2000)!
Here's to another 10 years! :cheers:

Roscosmos PAO: "The ISS Service Module Flew to the Station 10 Years Ago".

---------- Post added at 11:51 PM ---------- Previous post was at 07:21 PM ----------

From ISS On-Orbit Status Report for 12/07/2010:

FE-2 Tracy Caldwell-Dyson & FE-4 Doug Wheelock continued the IFM (Inflight Maintenance) on the CDRA (Carbon Dioxide Removal Assembly), finishing up CDRA back bed (#201) installation by mating the fluid, power, and data connections. [Remaining work includes installation of the hydraflow connectors (when the AR (Air Revitalisation) racks are swapped) and to clean the Node 3 AR rack AAA (Avionics Air Assembly), not required for Node 3 CDRA activation. All beds are installed and the rack swap will be scheduled in the next few weeks. The rack that is in Node 3 does not work in Node 3 so it has to move to the lab. This is due to 1553 comm. connection issues.]

Tracy unstowed, configured and installed the US EK (EarthKAM) hardware, for the first time in the unpowered WORF (Window Observational Research Facility) for a new session, powered by a Ku-band power supply unit. Unfortunately, errors were encountered on the laptop and the setup could not be completed. Over 50 schools have already signed up to participate.

FE-6 Shannon Walker unstowed the new NASA CubeLab-1 hardware and installed it for operation, then recorded documentary video of the setup and ensuing operations. [CubeLab is a low cost 1kg platform for educational projects. It is a multipurpose research facility that interfaces small standard modules into the ERs (ExPrESS Racks). The modules can be used within the pressurised space station environment on orbit, with a nominal length, width, and height of 100mm and a mass of no more than 1g. Up to 16 CubeLab modules can be inserted into a CubeLab insert inside an ER.]

FE-3 Mikhail Kornienko & FE-5 Fyodor Yurchikhin had ~3 hours set aside for an in-depth review of their upcoming EVA-25 (26/07).

Meanwhile, Shannon spent about an hour on gathering US EVA tools which will be supporting the Mikhail & Fyodor on their EVA.

Doug worked in the US A/L (Airlock) on his and Tracy's EMUs (Extravehicular Mobility Units), setting up EMUs #3010 & #3011 with their SCUs (Service & Cooling Umbilicals) and initiated the standard one-hour scrubbing process on the spacesuits’ cooling water loops, filtering ionic and particulate matter (via a 3 micron filter), then reconfigured the cooling loops and started the ~2 hour biocide filtering. [Loop scrubbing, including iodination of the LCVGs (Liquid Cooling & Ventilation Garments) for biocidal maintenance, is done to eliminate any biomass and particulate matter that may have accumulated in the loops.]

OGA Update:
The OGA (Oxygen Generator Assembly) H2 (Hydrogen) Dome ORU (Orbital Replacement Unit) is considered failed. The path forward is to finalize procedures to flush the acidic water from the current OGA recirculation loop and then replace the H2 Dome with the onboard unit. Currently, O2 (Oxygen) is at 158mmHg; Russian Elektron is on in 31 Amp mode.

From ISS On-Orbit Status Report for 13/07/2010:

Today Sasha, Misha & Tracy have their 100th day on orbit. Congrats!

Wheels performed the first steps of the scheduled X2R9 software transition, installing the first two R13 HDDs (Hard Disk Drives) with the upgrade in two PCS (Portable Computer System) laptops, followed by power-up and network connection. Four remaining R13 HDDs were installed later in the day. The old R12 drives and one spare R13 drive stowed. [MCC-H continued the transition of the C&C (Command & Control) MDM (Multiplexer/Demultiplexer) software to CCS (Command & Control System) R9, the Node 1 MDMs to NCS R4, the Payload MDMs to R9, and the PCS software step-up to PCS R13. The current C&C MDM configuration is as follows: C&C3 is prime, loaded with R9, C&C2 is backup, loaded with R8, C&C1 is standby with the new load but will be transitioned to backup this evening by ground controllers. Transitions activities will continue tomorrow.]

Roscosmos PAO: "ISS USOS Oxygen Generation System is Still Off".
The OGS (Oxygen Generation System) in the US section of the station is currently down. The leading cause of the system's failure is believed to be contamination of the membranes in the H2 (Hydrogen) dome. The pH of the water in the loop is around 4.0, which is causing a breakdown of some of the materials used in the construction of the dome leading to the contamination of the membranes. Teams in Houston are working on a plan to scrub the recirculation water loop before replacing the H2 dome with a spare kept aboard the station. The water scrub procedure also will be used to bring the pH up to a more neutral level. The oxygen level on the station will be maintained via Elektron and Progress tanks. Procedures to restore the OGS are expected to begin by the end of the week.

From ISS On-Orbit Status Report for 14/07/2010:

FE-2 Tracy Caldwell-Dyson performed troubleshooting activities on the EK (EarthKAM) system in the Lab which has a communication disconnect between its A31p laptop and the camera in the WORF (Window Observational Research Facility). Repair attempts were unsuccessful. Suspects are the EarthKAM software or the SSC (Station Support Computer). [EarthKAM was to be activated on 12/07 for a new session. This would be the 33rd time for EarthKAM aboard the ISS and the first time on Increment 24. The payload runs without crew intervention. EK is using a Kodak ESC 460C electronic still camera with 50mm and 180mm lenses, powered by 16 VDC from a 28 VDC adapter, taking pictures by remote operation from the ground, without crew interaction. It is available for students who submit image requests and conduct geographic research. The requests are uplinked in a camera control file to the ThinkPad A31p laptop which then activates the camera at specified times and receives the digital images from the camera’s storage card on its hard drive, for subsequent downlink via OpsLAN. ]

Propellant Transfers:
HSG (Houston Support Group)/Moscow reports completion of 116 kg of fuel transferred from Progress M-04M/38P to the SM. 188kg of oxidizer is being transferred today, followed by more prop transfer to the FGB tanks.

OGA Maintenance Status:
Ground teams are working on OGA (Oxygen Generation Assembly) repair procedures. Preparatory work is planned for tomorrow (15/07), followed by flushing and H2 (Hydrogen) dome replacement on Friday (16/07). If all goes well, we would expect to receive O2 (Oxygen) from OGA next Tuesday (20/07) at the earliest.

Roscosmos PAO: "ISS Reboost is to Take Place on July 16".
In accordance with the program of the International Space Station mission ballistics support, ISS reboost is scheduled for July 16.
The maneuver is to be assisted by 8 attitude thrusters of cargo vehicle Progress M-06M attached to Russian module Zvezda. The engines are to be started at 11:42:30 Moscow time, following the commands from the ISS RS central computer. As a result of the maneuver, the altitude of the ISS will become 3.7 km higher (355,2km) in order to provide favorable conditions for Soyuz TMA-18 landing and Progress M-07M docking.

Roscosmos PAO: "Hamster Pat May Create Additional Psychological Relief for the ISS Crew".
A hamster on-board the International Space Station may serve not only for science, but as a way to have psychological relief taking care about the pat, ISS Commander Alexander Skvortosov told through ISS Mail Box which works in Memorial Space Museum of Moscow with support of Roscosmos PAO and Moscow’s Department of Culture.
"Having a small rodent onboard the ISS would be not only useful for science, but also pleasant for the crew", Alexander noted. "But there are no small animals in the ISS Russian segment currently", RIA Novosti informs.

From ISS On-Orbit Status Report for 15/07/2010:

CDR Alexander Skvortsov performed an O2 (Oxygen) repress from Progress M-06M/38P section 2 tank. TsUP-Moscow informed the crew to open the valve and leave it open until all contents of the tank was emptied, resulting in a 9.5mmHg (12.8kg) repress.

FE-3 Mikhail Kornienko removed all remaining US CTBs (Cargo Transfer Bags) from MRM-1 for transfer to the USOS.

Software Transition Update:
X2R9 transition was completed yesterday (with some lessons learned).

Reboost:
A reboost of the ISS will be conducted tomorrow morning at 7:42:30 AM GMT, using Progress M-06M/38P Rendezvous & Docking thrusters. The purpose of the reboost is to set up phasing for the upcoming Progress M-07M/39P and Soyuz TMA-18/22S & Soyuz TMA-01M/24S flight operations. Burn duration: 17 minutes 45 seconds; delta-V: 2.1m/s / 6.9ft/s. Mean altitude increase expected: 3.6km / 2.0nmi.

From ISS On-Orbit Status Report for 16/07/2010:

FE-4 Wheelock had several hours reserved for continuing the OGA (Oxygen Generation Assembly) IFM (Inflight Maintenance), preparing for dome replacement on the weekend. [Activities included purging the OGS (Oxygen Generation System) H2 (Hydrogen) sensor and replacing it with a new spare, then mating all QDs (Quick Disconnects) to support subsequent ground-commanded pressurization of the dome ORU (Orbital Replacement Unit) with N2 (Nitrogen), finally unpowering the rack to prepare for next week's maintenance after the newly installed H2 sensor was purged with O2 (Oxygen) for safe powerdown. Wheels also scavenged an ITCS (Internal Thermal Control System) CSA (Coolant Sample Adapter) from Node 3 and used it with another ITCS CSA and a CWC-I (Contingency Water Container-Iodine) to set up for Flush operations. Additionally, Doug was to prepare a Pump ORU for next week's operations.]

ISS Reboost Update:
The reboost of the ISS this morning at 7:42:30 AM GMT was nominal. Using Progress M-06M/38P Rendezvous & Docking thrusters, the purpose of the reboost was to set up phasing for the upcoming Progress M-07M/39P and Soyuz TMA-18/22S & Soyuz TMA-01M/24S flight operations. Burn duration: 17 minutes 45 seconds; delta-V: 2.14m/s / 7.0ft/s. Mean altitude increase: 3.72km / 2.01nmi.

Roscosmos PAO: "Mice, Rats and Hamsters will Settle in the ISS".
Mice, hamsters and rats will settle in the International Space Station after 2012. IBMP official told Interfax-AVN. The rodents will live in new Russian Multipurpose Laboratory Module to be launched in two years from now.
MLM will host special support systems for the rodents. So, the experiments with small animals started in Mir will be continued in the ISS.
The rodent support systems are rather complicated as they are aimed to protect the crew against scent, harmful impurities and substances of the animals.
IBMP confirms that small animals will also maintain psychological comfort for the crew.
Multipurpose Laboratory Module will be a component of the International Space Station funded by the Russian Federal Space Agency and will be the last piece of the Space Station. Currently the MLM is scheduled to dock at the Zvezda nadir location. The MLM will be used for experiments, docking and cargo. It will also serve as a crew work and rest area. MLM will also be equipped with an attitude control system that can be used as a backup by the ISS.

From ISS On-Orbit Status Report for 20/07/2010:

FE-2 Tracy Caldwell-Dyson had several hours to perform the Day 1 activities of repairing the US OGS (Oxygen Generation System) which performed an unexpected "Fast Shutdown" on 05/07, probably due to blockage in several cells within the H2 (Hydrogen) ORU (Orbit Replacement Unit). [Since a sample in the OGS Recirculation Loop, brought home on STS-130/20A, showed a low pH (~4.1) and high counts of particulate, Tracy today performed the first of two separate planned flushes of components of the Recirculation Loop, connecting the potable water bus via QDs (Quick Disconnects) on the Water ORU for the flushing and then routing that water to the zone to be flushed. This required Tracy to mate/demate QDs throughout the flush program.]

The SPDM (Special Purpose Dextrous Manipulator) "Dextre" will be used to swap out a failed RPCM (Remote Power Control Module) on the P1 Truss this week. This will be the SPDM's first ever operational use.
Operations began on Monday when the SSRMS grappled the SPDM and maneuvered it to the P1 Truss worksite. On Tuesday flight controllers at MCC-H began conducting a "dress rehearsal" of the actual replacement as they commanded the SPDM to partially remove and reinstall a RPCM on the P1 Truss. After the SPDM successfully completes the test, MCC-H plans to swap the failed RPCM with a spare from the P3 Truss on Wednesday.

Here's an animation of the procedure.
