Astronaut training at Tsukuba Space Center, Japan

ESA astronauts Frank De Winne and André Kuipers were recently at the Tsukuba Space Center in Japan where they followed training for the Japanese Kibo laboratory and the H-II Transfer Vehicle (HTV).

De Winne is currently preparing for a six-month mission to the International Space Station (ISS). In May 2009, De Winne is scheduled fly to the ISS on board a Soyuz spacecraft together with Canadian Space Agency astronaut Robert Thirsk and Russian cosmonaut Roman Romanenko. Kuipers is assigned as back-up to De Winne.

BRIEFING SET WITH MEMBERS OF FIRST SIX-PERSON SPACE STATION CREW

HOUSTON -- NASA will hold a media briefing at 1 p.m. CST on Wednesday,
March 4, with the four future residents of the International Space
Station who will usher in an era of six-person crews living aboard
the orbiting research laboratory. The increase doubles the number of
people who will be living and working in space.

The briefing will originate from NASA's Johnson Space Center in
Houston and will be broadcast live on NASA Television. Questions will
be taken from reporters at participating NASA sites.

The briefing participants are:
- Roman Romanenko, Soyuz commander, Expedition 20 flight engineer and
Russian cosmonaut
- Frank DeWinne, Expedition 20 flight engineer and Expedition 21
commander (the first European Space Agency astronaut to command the
station)
- Robert Thirsk, Expedition 20 and 21 flight engineer and Canadian
Space Agency astronaut
- Nicole Stott, Expedition 20 and 21 flight engineer and NASA
astronaut

After the briefing, the participants will be available for photographs
and individual interviews, in person or by telephone. To participate
in the interviews, media should contact the Johnson newsroom at
281-483-5111 no later than 5 p.m. Friday, Feb. 27.

Romanenko, DeWinne and Thirsk will launch to the station aboard a
Russian Soyuz spacecraft in May. Stott will travel to the station
aboard the space shuttle Discovery in August.

NASA ANNOUNCES CHANGE FOR RETURN OF STATION CREW MEMBERS


HOUSTON -- The International Space Station Program has announced a
change in how two future crew members will return home. NASA
astronaut Nicole Stott and Canadian Space Agency astronaut Robert
Thirsk will swap seats on the space shuttle and Russian Soyuz
spacecraft to help ensure a timely homecoming for Thirsk.

Thirsk will launch to the station on a Soyuz in May and return to
Earth on that same vehicle in November, instead of aboard space
shuttle Atlantis at the end of the STS-129 mission. Stott, who will
launch to the station on shuttle Discovery's STS-128 mission, will
return aboard Atlantis with the STS-129 crew. She had been slated to
come home aboard the Soyuz that Thirsk now will occupy.

The change is in case of delays to future shuttle missions,
specifically STS-129, which currently is scheduled to launch in
November 2009. Such a delay could result in extending Thirsk's
mission beyond the six-month duration preferred for station crew
members.

Regarding the sleeping arrangements on this mission:

I'm assuming that Padalka and Romanenko are going to be sleeping in Zvezda, and I believe Wakata has moved his sleeping bag into Kibo.

Is Barratt sleeping in the "Temporary Sleep Station" in Destiny with De Winne and Thirsk sleeping in the two Harmony sleep stations?

Is STS-128 going to be bringing the final new Sleep station that would go into Kibo, and are there any plans to swap out the TSS for the new model?

TVIS Update: This upcoming week, TVIS engineers will be working on new IFM (Inflight Maintenance) steps to access the treadmill’s electronics box and flip small switches to allow for the stabilizer gain settings to be adjusted via the control panel if this is needed at a later date. This switch will override the software and ensure that the crew does not have to perform the stabilizer deactivation steps at every TVIS exercise session. Steps will also be developed for the crewmembers to open and inspect the anomalous forward right stabilizer. Work is already in progress to manifest spare parts on 2 J/A, and this assessment will help gain further insight into the current failure.

TVIS Update: Audio/video analysis of yesterday’s TVIS exercise tryout showed the same loud thumping and metallic noise at 5 mph that has occurred previously, plus some additional noise, even though all of the stabilizers were disabled at running speeds. Today’s shake test on all stabilizers is now being analyzed for noise and damage. For today, the treadmill is down, and until the TVIS is restored with more intrusive repairs to full service, exercise speeds on the belt will be restricted to ~4-5 mph. Currently CEVIS, ARED and VELO are fully operational.

BCC Checkout: MCC-Houston will perform a BCC (Backup Control Center) checkout today at 4:30pm-5:30pm EDT. The TDRS (Tracking & Data Relay Satellite) forward link will “swing” from MCC-H to the BCC in Huntsville, with a brief voice check on S-band from the BCC Capcom.

Ground Network Loss: Several hours before Soyuz docking on 5/29, all ground network communication services (command, telemetry, voice) between MCC-Houston and TsUP-Moscow dropped out completely for several hours. Thanks to the immediate response by our European partners who allowed voice comm to be routed to the ISS through their resources at COL-CC in Oberpfaffenhofen/Germany, docking activities could proceed. The outage lasted from 12:22am – 4:40am EDT. [The network dropout was later traced to a cut fiber optics cable in Helsinki/Finland.]

Vozdukh Failure: Yesterday (5/31, Sunday), the Russian Vozdukh CO2 scrubber failed due to a faulty AKV valve. The system was restarted and has returned to a nominal condition. [Research has shown that the valve is not engaging fully, due to the failure of a micro-switch. This is an existing problem and workaround procedures have been used successfully.]

Robotics Operations: Without crew involvement, ground engineers today performed Part 1 of a two-day robotics operation, remotely controlling the SSRMS (Space Station Remote Maneuvering System) to grapple the SPDM (Special Purpose Dexterous Manipulator) Dextre, releasing it from the MBS PDGF2 (Mobile Service System Power & Data Grapple Fixture 2) and maneuvering it to an overnight park position. Tomorrow, the SSRMS will stow Dextre on the Lab PDGF, grapple Node-2, complete an inchworm-like “walk-off” and maneuver to 2J/A docking position.

Nice.. but today we have Part2 of this scheduled work, dont we? Dextre is on Lab like You wrote but there is some miscorrection with dates, huh?

June 10:

OGS Status Update: The U.S. OGS (Oxygen Generator System) in the Lab has been exhibiting a rise in delta-pressure across the pump package assembly. The “shutdown” limit set in the software is 25 psi, and the data are trending exponentially upward toward this value within the last week. Engineers are working on procedures to clean the filter in the system in case 2J/A does not launch on 6/13 (a spare pump and filter are manifested on Endeavour). If launched on time, the plan is to replace the filter during the 2J/A mission and return the old filter. If the filter change-out is unsuccessful in reducing the rising delta-P, then the problems could be in the water ORU (Orbit Replaceable Unit). There is a spare ORU onboard but the R&R is much more intrusive than the pump-and-filter change. As of today, the procedure will be to shut down the OGS when delta-P exceeds 23 psi (1190 mmHg). OGS is now being moded to 100% production for a maximum of 48 hrs, to get extra O2 into the ISS interior before OGS shutdown. After 48 hrs, OGS is returned to 30% production, staying there until pump delta-P exceeds 23 psi. Changing to 100% allows maximum production over the final few days that OGS is operational (prior to the R&R).

TVIS Update: FE-2 Wakata completed the TVIS ACO (Activation & Checkout) this morning and recounted that everything felt and sounded nominal. Koichi reported that there were no anomalous sounds during the shake test on all four stabilizers. Additionally, during the exercise session, the TVIS was stable, unlike previous exercise sessions where oscillations were observed. Data and HD (High Definition) video recorded were downlinked for specialists to review prior to giving the crew a Go to exercise.

Let's recapitulate the OGS trends and wonder out loud if this could be the threat that raises STS-127's priority above the moon probe's:

NASA ISS On-Orbit Status 09 June 2009

The cleaning method is actually now not a preferred option.  There were issues with this procedure in ground testing.  Primary option now is to R&R the ORUs.  Since we don't have a pump ORU on-orbit, it's important that we get one.

An aside note, OGA was deactivated a couple days ago due to high O2 in the stack and the desire to use RS O2 from the Progress.  The current plan is to do the maintenance on the 19th if 2J/A does not launch.

So they have one pump ORU in the STS-127 manifest. Will they be flying another spare soon (just in case), or will they simply have to wait for repiar of the on-orbit unit back on Earth and send it back up. If the second is the case, how long do you estimate such a repair taking??

This ORU business (for the whole of ISS) scares me. Too many systems with sufficient spares, either tried and true but nearing EOL, or untested (on-orbit) units liek the DA that could have problems creep up. I think the funding levels need to be re-adddressed in this area, if we ever hope to 'maintain' a 6-person capability AND perform science, not alot of repair & troubleshooting.

Sure, the current radiator system set-up can handle the extra load, but we lost the redundancy. Until the spare flies, it's a tight situation. The NAPA auto parts store isn't down the street...

The unit coming up on STS-127 is the only spare we have until the old oncee is refurbished.  There is work to build pre-filters which will hopefully be an easier to maintain item than R&Ring the ORU.  I don't have the data on how long it would take, but it's on the order of several months to a year.

Wow, up to one year! Scary.
Of course the problem with a pre-filter is it creates a continuous delta-p at the inlet which reduces overall life expectancy. The change-out/cleaning rate will have to be quite frequent to avoid potential pump damage (assuming positive displacement pump).

Thanks.

There it is again, the old logistics problem.

Upmass. And bringing failed ORUs down - to learn from failures and to reuse them - seems to be very important. Whenever I read downmass is unneeded, I thinks of components like this, or CMGs, or the failed radiator panel, or SASA, or ...

Heck, how stupid can one be? Building a house in the wilderness and trashing the car to get there,

- hoping for public tranportation (COTS),
- hoping for hitchhiking (Soyuz, HTV, ATV) with massive luggage, which makes hitchhiking really hard and
- saving for a bicycle (Orion), which too can't transport the luggage and which we can't buy for many years because we have to save the money first and have to learn how to make bicycles.

You've got that right!

A couple of things I wonder about:

-How will we be able to replace large ORU's that we haven't predicted will fail and thus haven't stored them at the ISS once the Shuttle is gone?

-How will we be able to validate manned life support equipment that MUST function perfectly for a Mars mission module if we can't bring the failed components back to Earth to analyze the cause for failure?

Seems awful short sighted to me.

Yeah, I think with the radiator situation and with the logistics requirements, extending shuttle is a no brainer and needs to be done.  If NASA flies shuttle till 2015 that's just one year away from when the current planning horizon ends for US involvement in ISS. 

Perhaps NASA can say "okay, we'll keep shuttle and ISS flying till 2016 or 2017 then retire them both at the same time" then concentrate on the lunar/near earth asteroid flight program.  Or if they do decide to fly ISS till 2020 or later, then fly shuttle till 2015 and figure out some type of replacement that can do the same job.

OGS Status Update: The OGS (Oxygen Generator System) in the Lab was shut down early last Friday (6/12 because the cabin ppO2 had reached upper flight rule limits (close to 21 psi). If 2J/A is launched on 6/17 before the “Beta cutout”, the plan is to proceed with the water pump R&R (removal & replacement) during 2J/A. If the launch slips into July, more work on a forward plan for the R&R including risk & hazard analysis is required.

My worry for so long now, 'that old logistics problem' that Analyst uses so well.

Although, you don't even need to retire ISS so early. By having enough pre-positioned spares, you can at least provide a healthy margin to work with.

A bizzare twist: what about a Bigelow (or other) module to develop an on-orbit repair capabilitiy? We can't relay on Earth forever. Have a large internal volume to take apart CMGs, pump modules, NTAs. Those are skills worth expanding on. Granted those are HUGELY complex tasks, but definitely needed one day.

But we need the shuttle for now & the foreseeable future to bring those items up. Of course choice of replacement vehicle can change all that...  :)

STS-127 Launch Delay Update: US & Russian teams are in an intense process of replanning the timeline for the 2J/A mission, 33P undock, 34P dock, 17A mission, HTV mission, Soyuz relocation, and several software transitions, all of which having been impacted by the launch slip due to a hydrogen leak in ground support equipment and the prohibitive thermal Earth/Sun Beta angle “cutout” effect. Options being investigated include 2J/A launch on 7/11, delaying 33P undocking and 34P docking, or 2J/A launch on 7/17, with 33P undock and 34P dock prior to the shuttle mission. Teams are investigating other options including 33P undock prior to 2J/A mission and 34P dock after 2J/A undocking. RSC-E is also looking at a 34P launch on 7/24. 33P undock would be on July 1, and Soyuz relocation would be on 7/2-3, re-rendezvous test for MRM2 antenna functionality would be on 7/13. To set this flight program timeline a reboost using 33P propellant would be required prior to 7/1.

It has not been hard-scheduled yet, but it may be in the next week.  Currently there is enough O2 ullage with using the Progress O2 to get to past the currently-planned 2J/A launch, so ground teams are working to decide on the best repair plan and when is most beneficial to do it.

Per the previous post, OGA was fully deactivated today, which allows us to stay unpowered for a long period of time.

On the Expedition 20/21 mission Frank de Winne is flying for the ESA.  His mission is called OasISS.
Has ESA released what his OasIss Mission patch will be or a deicated ESA mission Press Kit yet?
Can anyone get these for us?
I have some OasISS patches. Let me know if you wish to receive one!

Rough Babelfish translation from TsUP about Progress M-02M undocking and approach to Zvezda on 12 July to test the Kurs system after the antennas were attached during EVA-22 on 5 June:

“PROGRESS M-02M”: SOON THE DISCONNECTING
Press service TsUP, on June 24, 2009
Approaches the completion the flight of cargo ship “progress M-02M” in the composition of the International Space Station. Crew of the ISS plots in the truck the equipment, which it is necessary to remove from the station, household trash.

On Monday June 29, transfer hatches will be closed, and on the following day “progress M-02M"  will leave for the autonomous flight.

The approximate time of disconnecting “progress M-02M” with the station - 22 hours 27 minutes on June 30 (18: 27 GMT). Space truck will free moorage in the docking module “Pirs”, who soon must engage ship “Soyuz TMA-14”. Now this ship is located in the service module of module “Zvezda”.

With the aid of “Progress M-02M” will be checked the fitness for work of new moorages - zenith port in the transition piece of module “Zvezda”. This operation it is intended to conduct on July 12. Test provides for the automatic rapprochement of truck with the station without the jointing.

ARED:
Quote
Bob Thirsk unstowed the IRED (Interim Resistive Exercise Device) and installed it in Node-2 and adjusted (tensioned) its canister spiral pulleys in order to increase canister loading.  IRED now serves as contingency exercise device as long as the ARED (Advanced RED) is out of commission.    [It was discovered yesterday that one of the dashpots (a mechanical device that resists motion via viscous friction) within the ARED VIS (Vibration Isolation System) is cracked and no longer attached.  Ground controllers reviewed the images and gave a No Go for ARED exercise until specialists could review and analyze the anomaly.  Instead, the IRED was put back in use.]

Today, on June 30, cargo ship “progress M-02[m]” was unjointed from the International Space Station. Command for the disconnecting was given out 22 hours 27 minutes Moscow time (18: 27 GMT) and after three minutes ship left moorage in the docking module “Pirs”. Time of the physical department of truck - 22 hours 29 minutes 43 seconds (18: 29: 43 GMT).
In the course of autonomous flight the flight tests of the modernized systems of cargo ship will be continued. But on July 12 is planned the test rapprochement “of progress M-02[m]” with s for the functional test of new moorage in the transition piece of official module “Zvezda”. In this case the mechanical contact of truck with the new attachment point is not provided for. [Osvobozhdennyy] from “the progress M-02[m]” moorage in the docking module “Pirs” must engage the manned ship “Soyuz [TMA]-14”, which at present is located in the service module of module “star”. Rejoining this ship with the crew in the composition of Gennadiy [Padalkya], Michael [Barratt] and To [koiti] [Vakaty] is planned on July 3. The estimated time of separation of ship from station - 01 hour 29 minutes (on July 2, 21: 29 GMT). Duration of the autonomous flight “Soyuz [TMA]-14” - about 25 minutes.

MEDIA ADVISORY: M09-119

NASA TV TO BROADCAST SPACE STATION CREW'S MOVE OF RETURN CRAFT

HOUSTON -- Three members of the International Space Station crew will
board a Soyuz spacecraft attached to the station and move it to a
different docking port on Thursday, July 2. The journey will be
broadcast live on NASA Television.

Expedition 20 Commander Gennady Padalka and Flight Engineers Mike
Barratt of NASA and Koichi Wakata of the Japan Aerospace Exploration
Agency will undock the Soyuz TMA-14 return spacecraft, from the
Zvezda service module and fly a short distance to the Pirs docking
compartment. The flight is expected to take about 30 minutes.

NASA TV coverage will begin at 4 p.m. CDT with undocking planned for
4:26 p.m.

While Padalka, Barratt and Wakata are aboard the Soyuz, Expedition 20
Flight Engineers Roman Romanenko of Russia, Bob Thirsk of the
Canadian Space Agency and Frank De Winne of the European Space Agency
will monitor the move from inside the station. Their Soyuz return
craft, the TMA-15, is docked to the Earth-facing port of the
station's Zarya module.

The relocation of Soyuz TMA-14 opens the Zvezda docking port for the
arrival of a new Russian Progress cargo vehicle in late July.

So the Progress will perform a re-rendezvous and approach exercise on July 12 (Sunday). Will NASA TV cover that live? I wonder what NASA's role in the hazard assessment analysis was, considering the 1997 experience with a redocking exercise that very nearly proved fatal for some or all of the Mir crew.

First off, I would presume that this second approach would use the new Kurs antennas on Zvezda zenith, whereas the Mir experiment turned off Kurs. Secondly, ISS has already had a Progress make a second approach and docking (Progress M1-4), so this is not a new experience for NASA.

Progress undocking
Quote
Progress M-02M/33P successfully undocked from the ISS DC1 nadir port at 2:29pm EDT after hook opening command at 2:27pm. [Lab and JPM (JEM Pressurized Module) science window shutters were closed for protection, and data for structural & dynamic analysis was obtained from the IWIS (Internal Wireless Instrumentation System) and SDMS (Structural Dynamic Measurement System). During departure, FE-3 Romanenko used the Nikon D2X camera with F80-400 mm zoom lens for taking photographs of the 33P docking assembly to verify that no rubber seals are missing on the interface and to assess seal integrity. 33P will free-fly for approximately 12 days and then perform a re-rendezvous test to the SM PkhO (Transfer Compartment) zenith port on 7/12 (Sunday).]

SSRMS ops
Quote
Wakata, Thirsk & DeWinne took the SSRMS (Space Station Remote Manipulator System) through the planned operations steps as FMA (Force Moment Accommodation) checkout. [Today’s activities were OCRs (On-orbit Checkout Requirements) in preparation for HTV (H-2 Transfer Vehicle) capture. The SSRMS will later be returned to Node-2 by ground control for Flight 2J/A.]

Updates on science troubleshootings (AgCam and EXPRESS Rack 4)
Quote
Mike Barratt performed troubleshooting of the AgCam (Agricultural Camera) software, transferring science data files for downlink and running diagnostics on the AgCam hardware.
Quote
Barratt & Wakata worked on the ER4 (EXPRESS Rack 4) M1 drawer, troubleshooting it to free it and return it to a nominal state, using their own devices. [The ER4 M1 drawer is stuck. It is believed that something is keeping the drawer lid from closing completely and it is catching on the rack, preventing the drawer from sliding out. Previous crews have unsuccessfully attempted to open the drawer using a number of tools.]

July 1:

Lots of stuff about the Soyuz relocation.
Quote
For tomorrow’s Soyuz TMA-14/18S relocation (PRST) from the SM aft port to the DC1 Docking Compartment nadir port, Padalka, Barratt and Wakata conducted a review of flight procedures and completed the standard 3-hr. PRST training drill for the mission using the onboard laptop-based simulator and supported by ground specialists via tagup on S-band/VHF-audio.
Quote
Also in preparation for the spacecraft relocation, Gennady Padalka spent an hour in the 18S Descent Module (SA) supporting a ground-commanded checkout of the Soyuz motion control system (SUD, Mode 2/“Docked”) which included pressurization of the Combined Propulsion System (KDU) Section 1 and Tank 1, a test of the pilot’s translational hand controller (RUD), and a hot firing of the DPO braking thrusters (1:12pm-1:28pm EDT). KDU maneuver thrusters and DPO lateral thrusters were not fired. [For the test, station attitude was handed over to Russian thruster control at 1:07pm, commanded to free drift at 1:12pm, then back to LVLH XVV (Local Vertical Local Horizontal/x-axis in velocity vector) attitude. The one-minute firing started on Daily Orbit 14 at ~1:15pm during an RGS (Russian Groundsite) pass. Attitude control was returned to the USOS (U.S. Segment) at 2:13pm.]
Quote
In preparation for tomorrow’s Soyuz relocation flight, Mike Barratt worked with Romanenko to configure & test the TV downlink from the Soyuz spacecraft and the SM over the MPEG-2 (Moving Pictures Expert Group 2) encoder via U.S. OpsLAN and Ku-/band in “streaming video” packets.
Quote
Heads-up on Soyuz TMA-14/18S Relocation (all times EDT):

Soyuz will be activated tomorrow (7/2) at 12:10pm EDT. Crew: Padalka, Barratt, Wakata.
- Remove BZV clamps – 1:10pm.
- Soyuz/SM hatch closing -- 1:30pm, followed by one-hour leak check.
- ISS maneuvers to LVLH undocking attitude at 4:42pm, goes Free Drift at 5:25pm.
- Orbital sunrise – 4:44pm
- TMA-14 undock command -- 5:26pm; physical separation -- ~5:29pm.
- Spacecraft (S/C) backs off SM aft end by about 25-30 m, performs stationkeeping.
- At ~5:35pm, S/C translates toward the USOS, rotating its heading by 90 deg angle in yaw and flying sideways “under” the ISS until stopping at second stationkeep point 25-30 m in front of the DC-1 nadir hatch (~5:43pm).
- Local sunset -- 5:47pm.
- During stationkeep, S/C rolls (“indexes”) to align angularly with DC-1 docking mechanism; crew adapts visually to darkness (with floodlight), then starts Final Approach.
- Final Approach begins ~5.50pm, ends with docking at ~5:54pm.
- Soyuz/DC-1 docking hooks & latches close ~6:10pm (after possible structural dynamics have damped out). After docking, there will again be a 1-hr. leak check.
- Hatch opening to DC-1 ~8:45pm, followed by QD (quick disconnect) clamps installation (to rigidize the interface) and “Pirs” ingress

COL ppO2 Sensor: Due to increased differences to MCA (Major Constituents Analyzer) measurements, the ppO2 (oxygen partial pressure) sensor in the Columbus laboratory is no longer considered reliable and is not being used anymore. The backup ppO2 sensor is still in range with the reference and gives good readings of the oxygen situation in COL.

GIVUS Failure: The GIVUS (Guidance Navigation & Control, GN&C) in the RS has failed. GIVUS is used for rate and attitude determination. TsUP-Moscow Motion Control System (MCS) specialists are still reviewing data but suspect that GIVUS is now hard failed. A spare GIVUS will be brought up on Progress 34P, scheduled for launch on 7/24. Meanwhile, the ORT backup up rate sensor has been powered up for determining station attitude, with the U.S. RGA-1 (Rate Gyro Assembly 1) used for attitude determination data as prime, and MCC-Houston has enabled the degraded RGA-2 as a backup to RGA 1. (Note: RGA-2 has a limited life due to one of its three laser gyros being degraded. The RGA 2 condition has been assessed and determined that it may not respond when attempted to be operated at cold condition in certain beta regimes.)

There are two competing requirements:
1. Progress at SM aft port for reboosts;
2. Progress at DC nadir port for Russian EVA's. If you have a Soyuz there, one cosmonaut has to be sitting inside the Soyuz while the EVA is going on (a Russian EVA cuts off the spacecraft docked at the DC from the rest of the station)

Anyways, there are currently only 3 available docking ports with 2 soyuz'es to be docked permanently for the 6 crew, making the equation quite complicated, with needs for relocation from time to time. The arrival of MRM-2 later this fall should make it easier, adding a fourth docking port to the complex.

It's that time of the year... We've heard about it from the shuttle side - here's what it does to ISS!

Tutorial on BETA ANGLE: Solar Beta angle is the angle between the orbital plane and the line-of-sight to the sun. Beta increases and decreases over time. A high positive or negative peak occurs approximately every 4 weeks. Generally, Solar Beta must not exceed 60 degrees which represents about ~72% sunlight per orbit. A few times per year, Beta magnitude (either + or -, i.e., above or below the plane) increases above 70 deg, which is called a high-beta pass. ISS is currently in a high-beta pass (see above value), and the vehicle is in constant solar insolation. This may seem good for the solar powered EPS (Electrical Power System), but continuous sunlight can cause batteries to overcharge. Overcharging results in temperatures and pressures above the nominal operational range, nearing maximum limits. Vehicle geometry may cause shadowing on some arrays which is sufficient to prevent battery overcharging. If not, ground controllers must shunt (turn off) solar array power to the batteries to simulate an eclipse (night time) and discharge the batteries. This may be required every 4-12 hours. A charge rate PPL (Pre-Positioned Load) may also be loaded to the EPS MDMs (Multiplexer/Demultiplexer, computers) to reduce the current into the batteries during charging. Each power channel has a slightly different shadowing profile and battery chemistry, so the type and frequency of action is not uniform for all channels. Nonetheless, all action is performed per standard ground procedures.

Mike Barratt & Frank DeWinne conducted a 2-hr high-level OBT (Onboard Training) review of the latest HTV (H-2 Transfer Vehicle) approach monitoring & robotics/capture procedures and cue card. An HTV crew conference is planned tomorrow to discuss details, followed by more preparatory training events in the future.

All six crewmembers performed the mandatory two-hour OBT (onboard training) emergency egress drill for the case of rapid cabin depressurization, with Russian & US specialists standing by at both control centers for crew questions or comments, followed by a 20-min debrief with ground specialists. [Background: Purpose of the drill is to (a) familiarize the station residents with the location of hardware and the positions of valves used in emergency situations, (b) work through the Russian Segment (RS) hardware deactivation procedures, (c) practice crew emergency joint activities, and (d) identify crew comments and suggestions that arise during training regarding crew procedures and equipment. In the RS, the crew translated along the emergency egress paths to the nadir-facing ports of the DC1 and FGB (where Soyuz 18S & 19S, resp. are currently docked), checking hardware such as the Sokol suits, cable cutters, fire extinguisher (OKR), gas masks (IPK), emergency procedures books, valve settings, hatch rubber seal & restraint integrity, etc. In the US Segment (USOS) the inspection focused on fireports being unblocked in the Lab {21}, with other US modules to be checked by future crews), readiness of CSA-CP (Compound Specific Analyzer-Combustion Products), ISS leak kit, PBA (portable breathing assembly) and PFE (portable fire extinguisher), emergency procedures books, valve settings, integrity of hatch rubber seals, presence of hatch handrails, etc. The checks also included Node-2, COL (Columbus Orbital Laboratory), JLP (Japanese Experiment Module Experiment Logistics Module Pressurized Section) and Kibo JPM (JEM Pressurized Module). The exercise was topped off by a thorough debrief with the ground via S-band. During the session, the crew simulated executing the planned emergency procedures while moving about the station. For the case of an onboard fire and for emergency descent, there are other mandatory emergency drill OBTs.]

Padalka & Romanenko spent two hours on an in-depth refresher review of procedures and recommendations for the Progress 33P repeat rendezvous on 7/12, rehearsing steps for monitoring the test approach of the spacecraft, reviewing docking data and tagging up with a training instructor at TsUP/Moscow.    [The re-rendezvous  is planned with the following stages:

    * KURS activation on 33P – 11:28am EDT,
    * SM Final Approach enable – ~12:33pm,
    * Begin Flyaround at 400-m ~12:37pm,
    * Final Approach initiation – 12:58pm,
    * Start “breakout” maneuver (two burns) – 1:10pm & ~1:15pm.

The 33P test is conducted to verify that the KURS-P antennas are installed correctly on the SM PkhO (Service Module Transfer Compartment) zenith docking port.  It is planned to abort (stop) the approach at a range of ~11.5 m, followed by the “breakout” maneuver.]

For monitoring the 33P re-rendezvous test, Roman & Mike installed & tested the RS (Russian Segment) video system, which uses the SONY HDV camera for transmitting over the MPEG-2 (Moving Pictures Expert Group 2) encoder from FGB & SM to downlink “streaming video” packets via U.S. OpsLAN and Ku-band, involving the FGB-based A31p SSC (Station Support Computer) laptop for the TV conversion to NTSC and Ku-band.   [The A31p was later deactivated again.]

Barratt conducted troubleshooting on the ENose (Electronic Noise) instrument in the ER-2 (EXPRESS Rack 2), restarting the unit, checking its TCP-IP address and performing re-initialization tests.  [ENose monitors the station’s interior for harmful chemicals such as ammonia, mercury, methanol and formaldehyde, running continuously and autonomously. It is the first instrument aboard ISS which can detect and quantify chemical leaks or spills as they happen. If successful, ENose might be used in future space missions as part of an automated system to monitor and control astronauts' in-space environments. The shoebox-sized ENose contains an array of 32 sensors that can identify and quantify several organic and inorganic chemicals, including organic solvents and marker chemicals that signal the start of electrical fires. The sensors are polymer films that change their electrical conductivity in response to different chemicals, where the pattern of the sensor array's response depends on the particular chemical types present in the air. The instrument can analyze volatile aerosols and vapors, help monitor cleanup of chemical spills or leaks, and enable more intensive chemical analysis by collecting raw data and streaming it to a computer at JPL's ENose laboratory. The instrument, weighing less than nine pounds and requiring only 20 watts of power, has a wide range of chemical sensitivity, from fractional parts per million to 10,000 parts per million. Its data-analysis software can identify and quantify the release of chemicals within 40 minutes of detection. While ENose will look for 10 chemical types in this six-month experiment, it can be “trained” to detect many others.]

BGA 2B Issue:    Yesterday, BGA 2B (Beta Gimbal Assembly 2B) on the port solar array began to exhibit an increased number and frequency of high current events (motor current >0.75A) while in autotrack mode with the BGA Autobiasing function enabled.  Ground controllers took over manual control which “unstalled” the drive motor, but after more efforts the BGA is currently stuck at 163.9 deg.  Power generation is sufficient, but the decreasing solar Beta angle is bringing the current position into a hazardous longeron  shadowing condition.  The autobiasing of the associated Port SARJ (Solar Alpha Rotary Joint) has been inhibited and manual biasing started to account for the current position of BGA 2B. No options for un-sticking BGA 2B have been identified yet.

A minor occurrence of smoke in the Russian segment is being discussed on the live Station audio feed.  Houston does not sound concerned but reminded the crew to be prepared for any further indications. Moscow is discussing the situation with the Russian crew and recommending activation of a filter and additional air sampling.  The crew describes the "CCP" as being normal and that the smoke came from panel 431 which they powered down.
BTW, Houston also reported some success in getting the balky BGA 2B to move--~3 degrees. The crew is not yet asleep and Houston gave an update on trouble shooting efforts which should not trigger any audible warnings on-board.

The joint operated with better performance than was seen in previous days before it stalled. BGA 2B has been parked at 225 degrees which is a good config for both 33P Re-approach and 2J/A Docking.

BGA 2B Update: Today ground controllers commanded the BGA 2B (Beta Gimbal Assembly 2B) on the port solar back to nominal autotracking of the sun. The recent anomaly (jamming) experienced by the 2B BGA was believed to be due to the high Beta angles which caused thermal expansion of the BGA components. Now that Beta angles have decreased, no additional issues are anticipated with the 2B BGA.

Rapid Depress Manual Response Issue: Late last week it was discovered via testing that a manual crew response in the RS to a rapid depressurization event does not trigger automated safing for the USOS, although proper responses via automated alarms in the RS and USOS do occur. The issue is that coding in RS software was changed for an update, but was not picked up by USOS software. Procedures are in work by the FCT (Flight Control Team) to uplink for crew cognizance and action in the event the situation occurs. It has been determined the likelihood of this situation occurring is very low.

RED Update: RED (Resistive Exercise Device) canister cords have reached cycle life based on estimation of use by six crewmembers since ARED (Advanced RED) has been down. RED engineers have approved a life extension, but even so the canister cords will still reach the new life limit likely by tomorrow (7/15). A plan is in place to have each crew member inspect the canister cords after each exercise session and to use safety straps. Discussions are underway to schedule a canister cord replacement.

[edit]

I did find:

Mike Barratt & Bob Thirsk had 3h 45min set aside for troubleshooting the heater problem of the CDRA (Carbon Dioxide Removal Assembly) in consonance with the ground in an attempt to recover nominal CDRA operations. [The crew took resistance measurements of several connectors to determine specifically which internal CDRA components were potentially shorted and to verify the associated cabling was wired in accordance with expectations. An overnight review of the resistance measurements taken yesterday along with photographs of the connectors downlinked to the ground revealed the harness was not built to print. Once the cabling assessment was completed the crew was given the go-ahead to cut the wires to the shorted heater string. CDRA was subsequently re-installed and re-started. At this writing the available heaters are working nominally and CDRA is in warmup with an expectation of nominal operation around 6:30pm EDT. During the CDRA outage onboard exercise was deleted and LiOH canisters were activated as required in order to manage CO2 levels.]

I don't know how the harness could have been wired improperly.  It likely happened many years ago, so I don't think we'll ever know.

Most of the issues we've had with CDRA relate to particles from the Desiccant beds clogging valves.  This happens because as air moves through the beds, the Desiccant rubs together and forms small particles that go downstream.  It gets stuck in the valves and in a check valve that prevents dumping cabin air overboard.

This was mitigated several years ago by re-designing the beds and installing sock filters upstream of each of the valves.  These filters are inspected and cleaned as needed on a regular basis.  We still have an issue with this as one of the current beds has been showing a large delta pressure across the bed recently and will need to be changed out soon.

The only other "failures" we've had with CDRA relate to software thinking there was an issue when there was not.  Also, the software sometimes gets out of sync with the hardware.  We've seen this in the fan not turning off when it's supposed to, but resolves itself when re-commanded.  Interestingly enough, it also happened during the manual operations during 2J/A.

If anybody else is interested in ECLSS hardware issues or design, ask me questions and I'll answer them to the best of my ability.  Probably need a separate thread, since it's beyond this increment.

New Software Load (On-Orbit X2-R8, PCS R12 & MSS R6.2). Today, the Backup and Standby CCS (Command & Control System) computers were successfully loaded with CCS R8. The Cupola and A/L PCS (Airlock Portable Computer System) hard drives were swapped out, upgrading to the R12 version (see above). Tomorrow, the Backup CCS will be transitioned to prime, enabling the CCS R8 load and the final CCS computer will be loaded with CCS R8. All activities associated with the transition continue to proceed nominally.

New Software Load (On-Orbit X2-R8, PCS R12 & MSS R6.2). The first two days of the X2-R8 software transition have gone very smoothly. Today, after a recovery of the JCP computer in the Kibo module, the ground performed a Primary C&C Transition to bring CCS R8 into Primary. After the transition, the crew was given the GO from MCC-H to connect the R12 PCSs at the Cupola RWS and then in the AL. Following this they then swapped the prepositioned R12 HDs into the remaining PCS laptops (see above) and powered them all on so they can be patched overnight from the ground.

ATA Isolation Test: Yesterday, the ground completed a P1 ATA (Ammonia Tank Assembly) Isolation test yesterday which kept the ETCS (External Thermal Control System) Loop B isolated from its ammonia tanks for over 4 days (111 hrs). All parameters remained within expected ranges while isolated from its tanks. This information, which will be used to validate engineering models, has increased confidence that the ETCS can operate nominally in support of the ATA R&Rs during 17A(P1) and 19A(S1).

Has anyone here heard anything about the MPC (video system) on ISS having problems, and perhaps recently getting fixed?  We didn't get any HD feeds down from ISS during STS-127, but we may have gotten the Tim Kopra / Finland event down in HD on Monday, so I was wondering if the MPC problem is fixed now.

Maybe they just didn't have enough bandwidth to send HD. I guess there are tons of video/pictures/data that needs to be sent down during a shuttlemission.

No, that's unrelated. Your theory wouldn't explain why we got HD on the other shuttle to ISS missions. (Plus in the HD thread, it was mentioned that NASA had problems with the MPC :) )

False Onboard Fire Alarm Events: Several FGB fire & smoke C&W (caution & warning) false alarms were annunciated yesterday. FGB signatures led to multiple systems shutdowns in the RS (Russian Segment) for approximately 30 minutes. This morning, systems were back to nominal; teams are analyzing the data. It is believed this was not related specifically to the new CCS (Command & Control System) R8 software upgrade but was indirectly caused due to the period of time with loss of sync between the RS and USOS MDMs I(Multiplexer/Demultiplexer computers). The FGB smoke detector capability currently has the auto response disabled for approximately the next 24 hours to allow specialists to evaluate the telemetry data and ensure that there are no additional anomalies. FGB smoke detectors are currently working in the telemetry mode and either the ground or crew can initiate the auto response. In addition, smoke detector capability is available in the SM and Node-1.

It was a sync issue caused by the C&C MDM swap during the R8 step up.  The FGB went out of sync for a short bit with the C&C MDM.  It was fixed when the computers sycned up again.

SKV1 Issue & Khladon-218 Spillage: Yesterday’s IFM (Inflight Maintenance) on the Russian SKV1 air conditioner failed. After installing the new BTA heat exchanger, the crew at first reported that one of the Khladon-218 (Freon) line connectors between the BTA and the compressor was leaking (Khladon pipeline 2). After lengthy troubleshooting of this connector involving demating, remating, and tightening, TsUP-Moscow had the crew remove & replace the metal gasket in the line 2 connector. This proved unsuccessful as well, and the Khladon pipeline 2 adapter was swapped with the Khladon pipeline 1 adapter. Once the swap was completed, the crew reported that both connectors were in fact leaking. According to TsUP specialists, approximately 5 grams of Khladon were released into the cabin. SKV1 is still not functional, whereas SKV2 is performing nominally.

listen to the first ten seconds of the Kopra event.

Uses the ISS crew always two microphones by media events?? 

Only by HD events uses the crew a normal microphone (gives a better audio signal )

Not all ISS HD video material used NASA for broadcast on the NASA TV HD channel

WHC Pretreat Tank Troubleshooting: Yesterday, after an automatic refilling of the flush water tank of the Waste & Hygiene Compartment (the US toilet), the “Bad Pretreat” LED (Light Emitting Diode) indicator was illuminated. Mike Barratt performed troubleshooting steps to recover the WHC including verifying valve position and performing a functionality test. Later, after performing multiple flushes, the error was cleared and the crew was Go for nominal WHC use. Specialists believe the problem was air bubbles in the line that can happen after the automatic fill of the flush water tank.

More WHC (Waste & Hygiene Compartment) Troubleshooting: Yesterday, after troubleshooting cleared up Friday’s “Bad Pretreat” LED (Light Emitting Diode) indicator, this morning another problem prevented WHC usage by the crew: Annunciation of the red “Check Separator” light. While the crew continued to use the SM ASU toilet, more troubleshooting and a functionality test were being developed for the WHC.

===

WHC (Waste & Hygiene Compartment): Yesterday, more troubleshooting to investigate the “WHC Check Separator” indicator light annunciation, which included providing additional flow through the unit, cleared the indication and the unit was returned to nominal operation. It appears there is an intermittent sensor in the system which will be monitored for analysis. A review of the two incidents is underway to determine whether they are related.

The International Space Station Russian Segment (ISS RS) Onboard Computer System (OCS) housed a new software (S/W) version [08.03 - anik] required to operate a new Russian Research Module MRM-2, whose integration into the ISS RS is scheduled for this autumn.

RSC Energia's specialists developed this software.

S/W installation was conducted by RSC Energia's specialists, specialists from Lead Operations Control Group and Mission Control Center (MCC-M) using the MCC-M - ISS RS communication channels. Russian cosmonauts G. Padalka and R. Romanenko working as the members of ISS Prime Crew 20 (ISS-20) took an active part in preparatory works on S/W installation and monitored the installation process.

By telemetry data, the Onboard Computer System with the new software version installed operates in a design mode.

Airlock RPC Trip: Late last Friday (8/14), RPC-7 (Remote Power Controller 7) in the RPCM (RPC Module) AL1A4A_B, a kind of fuse, tripped open. This RPC powers the A/L (Airlock) Zone 1 primary shell heater that covers the circumference of the CL (Crewlock). The trip was due to over-current, and the RPC was declared No-Go for re-closure. A/L secondary heaters are capable of maintaining temperatures in this zone as required for the near term but at the current solar Beta angle heaters are not required to be powered on for temperature control, and the Zone 1 secondary heaters were temporarily disabled following the RPC trip. Specialists are working on a forward plan.

With the US OGS (Oxygen Generator System) currently down (see below), CDR Padalka & FE-3 Romanenko in the course of the day ignited three more end-of-certified-life SFOG (Solid Fuel Oxygen Generator) “candles” in the RS (Russian Segment).  [The SFOGs, used as oxygen source backup to the Elektron and OGS, generate O2 by decomposing cartridges of solid potassium perchlorate (KClO4) into potassium chloride (KCl) and O2 when heated at 450-500 degC. Each candle releases ~600 liters (1.74 lbs.) of O2, enough for one person per day.]

After getting ready for the OGS IFM (Inflight Maintenance) yesterday and setting up the video equipment for ground monitoring, FE-4 Thirsk & FE-5 DeWinne accessed the OGS Rack to perform the troubleshooting of the failed OGA (Oxygen Generator Assembly), removing & replacing the OGS pump ORU (Orbit Replaceable Unit) filter, located behind the water inlet QD (Quick Disconnect), then re-connecting the H2 sensor, followed by leak checking some time afterwards.    [The IFM was not successful.  After the OGA pump filter replacement, the pump delta pressure did not decrease.  The pressure was high at 21.8 psid, too close to the operational limit of 23 psid to be worth starting up.  More analyses are underway to determine a new plan.]

Continuing the elusive troubleshooting of the failed U.S. OGS (high delta-pressure), Bob Thirsk & Tim Kopra –
•   Deactivated and temporarily removed the ALTEA (Anomalous Long Term Effects on Astronauts) dosimeter unit (without disconnecting its cables) to allow OGS rack access,
•   Performed HOPA (Hydrogen Sensor ORU Purge Adapter) disconnect & purge,
•   Removed & replaced the OGS water ORU (Orbit Replaceable Unit), a 1h:15m task for one crewperson,
•   Reconnected the H2 sensor and
•   Closed out the worksite.
[If today’s R&R proves unsuccessful, the failure of the OGS could impact the 17A mission. The CSCS (Contingency Shuttle Crew Support, i.e., “Safe Haven”) supply of O2 would allow 63 days (vs. 79 days required). Engineers are looking at options to make up the days if necessary, including reducing crew size, manifesting extra O2 on Progress or HTV1, etc. To be discussed at the L-2 on 8/23.]

Houston just reported to ISS that the Oxygen Generation Assembly repair was successful and that the OGA is producing oxygen with a lower partial pressure than when it was originally turned on.  The crew joked that were just starting to discuss around the dinner table who was going to have to go home early if the repair didn't work

To add a little more detail, the delta pressure (not partial pressure) across the pump was approximately 6.5 psi, which is less than what was seen during the very first OGS activation and much much less than what was seen on Tuesday (22 psi).  Teams will be looking at the best course of action to try and get to root cause without bringing the ORU home (no space on 128).

Emergency Lighting Power Supplies (ELPS): The onboard ELPS units are coming up on their ten-year life certification expiration in September. This led to an on-orbit ELPS capacity test last night. The light stayed on bright for 2.5 hours and another 1.5 hours at reduced intensity, indicating the units are still fully operational.

It is acronym time - NASA speach - again: We are talking about flashlights, battery powered

Are you sure these are just generic flashlights? That last 10+ years?

No, these are not flashlights.  They are strips of lights that run off batteries.

OGS Status Update:  On 8/21 (Friday) the crew successfully replaced the suspect Water ORU (Orbital Replacement Unit) with a new unit.  The OGS (Oxygen Generator System) was started successfully on the same day, and the delta pressure across the pump ORU came up with a nominal value and has remained so over the weekend (currently running at ~7.8 psid).  The OGS is now considered to be operating nominally.(ISS On-Orbit Status 08/24/09)

COL CMU R&R Update:  Frank De Winne’s R&R of the CMU1 (Command & Monitoring Unit 1) of the COL DMS (Columbus Orbital Laboratory Data Management System) on 8/21 was successful. ESA is reporting that the unit is working nominally. [CMU1 is one of four units in the DMS. The failed CMU1 was prepacked for return on 17A.]

ATA Replacement Planning: In preparation for the ATA (Ammonia Tank Assembly) swap on EVA-2 & -3 during the 17A docked period, the tubing (not the already isolated tank) in the P1 truss will be vented by ground control starting on FD2 (Flight Day 2) to reduced pressure in the tank QD (Quick Disconnect) lines. A very small amount of ammonia (NH3) will be dumped overboard (approx. 2.5 lbs). Contamination will be minimized with off-flight-direction pointing. The vent valve will be kept open for 4 days, until shortly before EVA-1, as a safeguard against a leak in an isolation valve. If such a leak should occur and is large enough to produce NH3 ice crystals, they would be expected to be seen prior to Orbiter arrival (FD3), and action would be taken to stop the leak. A slow leak would only produce NH3 vapor and should not be a concern. [If the vent fails, one tank isolation valve will be opened to reduce the over pressurization risk. Nitrogen (N2) will be vented from ATA on FD4, the day before EVA-1. Established decontamination procedures will be in place in case of accidental ammonia contamination of the EV crew.]

More Kudos from POIC (Payload Operations Integration Center) to Crew: “Mike and Tim: Thanks to you both for completing the final two of 15 LOCAD surface sampling sessions for this Increment. You have collected a wealth of excellent and interesting data. Thanks so much for the fantastic job!”

MAXI Troubleshooting: JAXA SSIPC (Space Station Integration & Promotion Center/Tsukuba) is currently in the process of troubleshooting the MAXI (Monitor of All-sky X-Ray Image) payload, mounted external to the Kibo module on the EFU (Exposed Facility Unit). The problem is with the MAXI MRDL (Medium Rate Data Line) data transfer which has stopped. LRDL/Low Rate Data Line traffic is nominal.

SKV-1/SKV-2 Update: The Russian SKV-1 air conditioner is now fully functional, after ~2 years of inactivity. Russian teams are troubleshooting SKV-2 and believe its problem could be a false low temperature indicator. Analysis continues.

SSRMS Readiness: Yesterday’s MSS/SSRMS (Mobile Service System/Space Station Remote Manipulator System) activities to complete final OCRs (On-orbit Checkout Requirements) for HB (Hot Backup) capability for HTV were all successful. SSRMS is ready for 17A and HTV.

Specialists of RSC Energia, Lead Operations Control Team and Mission Control Center (MCC-M) with active participation of the Russian cosmonauts Gennady Padalka and Roman Romanenko who are working on-board the International Space Station as part of Expedition ISS-20/21 have carried out in August a series of unique activities to install new high-precision instrumentation and equipment in the Russian segment of ISS.

For the first time in history, a set of instruments for high-precision angular rate measurements has been replaced, as scheduled, on-board a space station in flight. A new set of these instruments with improved performance has been installed and tested.

Also, new and improved on-board measurement system instruments have been installed.

The tests that have been run on the newly installed instruments and equipment have shown that they operate normally.

Conjunction Update:   Further tracking of the debris object (Ariane V debris, SYLDA, #29274) showed a Collision Probability of zero.  A DAM (Debris Avoidance Maneuver) was not required.

CBM Bolt Failure:   The Node-2 Nadir CBM (Common Berthing Mechanism) bolt 4-1 was commanded to retract early today, to troubleshoot high torque indications seen on 17A MPLM berthing.  During the retraction, the bolt reached its torque limit and stopped turning.  A second attempt to retract the bolt was made, but resulted in no additional turns.  The current bolt configuration does not allow MPLM unberthing. The bolt and nut will be replaced with on-orbit spares in an intravehicular R&R currently in planning.

ROBoT Simulation Issue:  Yesterday De Winne & Stott were unable to complete HTV Track & Capture training due to an excessive delay between hand controller input and simulation response. This onboard training, required in preparation for HTV1 capture, could potentially return to the previously used configuration for some objectives.  A forward plan is under review.

PMA-3 Heater Cable Installation:    After the EVA-2 [STS-128] crew discovered that the PMA-3 (Pressurized Mating Adapter 3) is rotated (“clocked”) 90 degrees off (“tail nadir”) from the expected orientation (”tail aft”), further evaluation by ground teams confirmed that the on-board jumper harness is not long enough in this orientation.  Therefore, this task will not be performed during EVA-3.  It was also confirmed that the actual PMA-3 orientation is the same as in 2007 (Expedition 15) before it was relocated to Node-1 nadir, and that this is the correct orientation expected for HTV rendezvous/berthing.   There are currently no plans to rectify the situation which requires that entrances to PMA-3 need to be restricted to certain (solar-heated) Beta angle periods to prevent condensation within the module.  The root cause for this discrepancy is under investigation.

Conjunction Alert: NASA FCT (Flight Control Team) is alerted to two conjunctions of the ISS with Object 30535 (Chinese Fengyun 1C debris). The first TCA (Time of Closest Approach) of concern is on 9/9 (Wednesday) at 4:37am EDT, or approximately 13 hrs after undocking. The second TCA is at 9/9 at 6:08am. The ISS FCT is working options for performing a possible stand-alone posigrade DAM (Debris Avoidance Maneuver) after Shuttle undocking. The debris avoidance timeline currently being considered assumes ISS would maneuver to avoid the earlier TCA (4:37am). This maneuver would utilize the Progress 34P R&D translational thrusters. A mated DAM, with Shuttle, is not being considered at this time.

Russian thrusters will be disabled during the period 2:10pm-5:50pm due to loads constraints, and the MT (Mobile Transporter) will then be rolled from WS-4 (Workstation 4) to WS5 in preparation for HTV arrival.

TDRSS Update: Ground engineers continue to work on risk mitigation plans arising from the failure of a timing unit in the STGT (Second Tracking & Data Relay Satellite System Ground Terminal) at WSC (White Sands Complex), which could affect users of the TDW (TDRSS West) and TDE (TDRSS East) satellites, i.e., Shuttle, ISS & HTV.

Russian BVS Computer System: The TVM Terminal Computer System on the SM (Service Module) lost one of its redundant subunits. Two (of three) lanes continue to work normally on both the TVM and the TsVM (Central Computer System).

Space Mice OK: The MDS (Mice Drawer System) is nominal, with its six occupants reportedly feeling great (food bars are now again being fed automatically through the repaired mechanism). MDS is a new type of housing unit for mice in space that was built by ASI (Italian Space Agency) to investigate the genetic mechanisms underlying bone mass loss in micro-G, particularly testing the hypothesis that mice with an increased bone density are likely to be more protected from osteoporosis, when the increased bone mass is a direct effect of OSF-1 (Osteoblast Stimulating Factor-1), a protein involved in skeletogenesis (skeleton formation). Research conducted with the MDS, implemented under an agreement with NASA, serves as a model for the effects of living in space on the human body, and will help solve medical problems experienced by space travelers. The increased knowledge of physiology may also benefit medical approaches to disease on Earth.

Not to be totally negative but NASA/ESA/RSA hailing a 6 member crew seems kind of hollow shortly after it occurred. Down to five then to TWO for a short time means nothing but on-board maintenance till back up to five. Six will not come back until 22S in almost six months when 20S gets swapped out--if the Russians don't send another tourist.

Soyuz 20S Launch Preview: Pre-launch activities for Soyuz 20S are continuing without issues at Baikonur, Kazakhstan. The launch is scheduled on 9/30; final launch decision will be made on 9/25 (Friday).

MRM-2 Altitude Strategy: For the docking of the Russian 5R/MRM-2 (Mini Research Module 2) on Soyuz-U on 11/12, ISS altitude needs to be lowered. The attempt will be made to achieve the reduction by removing the SA (Solar Array) biases originally implemented to reduce orbital drag. An additional drag component could be added by positioning the Starboard SARJ (Solar Alpha Rotary Joint) suitably. Later, a reboost will be required to recover the lost altitude but this can be accomplished by the Shuttle during mated operations with STS-129/Atlantis/ULF3 in November. The SA positioning would save about 75-150 kg of propellant. [“Night Glider” drag reduction biasing of the solar arrays with BGAs (Beta Gimbal Assemblies) has been in use since the early days of ISS ops.]

Might this mean more margin or upmass possible for STS-129?
Also might this change the launch time (or not, since drag/lower altitude doesn't change the orbital plane)?

From NASA.gov today:

Amid its continuing science and maintenance duties, the International Space Station’s Expedition 20 crew saw the departure of the ISS Progress 34 (P34) cargo craft, transferred cargo from the Japanese H-II Transfer Vehicle (HTV) and practiced robotics procedures Monday.

Early Monday morning, the P34 undocked from the aft port of the Zvezda service module. The resupply ship, which arrived at the station July 29, is moving to a parking orbit to conduct several thruster firings associated with a science experiment for Russian researchers. The Progress is slated to deorbit Sept. 27.

The crew members spent time transferring cargo from the HTV and brushing up on robotics procedures. Flight Engineers Michael Barratt, Nicole Stott, Frank De Winne and Robert Thirsk will employ these procedures Wednesday when they use the space station’s robotic arm, Canadarm2, to grapple and remove the Exposed Pallet of science experiments from inside the hull of the Japanese cargo craft. Canadarm2 will then hand the pallet off to the Japanese Kibo laboratory’s robotic arm, and it will be mated to the Exposed Facility science platform at the back end of Kibo. Thursday, the experiments will be grappled and released individually for installation on the Exposed Facility. The Exposed Pallet will be returned to the HTV Friday.

Included on the Exposed Pallet is the Hyperspectral Imager for the Coastal Ocean and Remote Atmospheric and Ionospheric Detection System Experiment Payload, which consists of two instruments. The experiment is designed to perform a comprehensive study of upper atmospheric airglow emissions. Its observations will be used to develop and test techniques for remote sensing of the neutral atmosphere and ionosphere on a global scale.

The Superconduction Submillimeter-wave Limb-emission Sounder (SMILES) experiment is also among those on the pallet. SMILES is aimed at global mappings of stratospheric trace gases that are related to ozone depletion.

Not including the space shuttle, three cargo vehicles from around the world have now supplied the International Space Station with cargo. Russia’s Progress vehicles have continuously supplied the station since 2000, Europe’s Automated Transfer Vehicle first arrived in April 2008, and Japan’s HTV completed its maiden voyage Thursday, Sept. 17.

Stott also participated in the Integrated Cardiovascular experiment, which studies the effects of long-term spaceflight on the size of the heart and the flow of blood in a crew member’s body.

FE-1 Barratt, FE-2 Stott, FE-4 Thirsk & FE-5 De Winne continued the extensive task of putting together & installing the new COLBERT treadmill (T2) in Node-2. Today’s installation steps, spanning several hours, included –

    * Removing the bumpout & temporarily stowing the T2 rack at the Node-2 forward end cone,
    * Continuing routing, begun yesterday, of supply, return, power & data jumpers throughout Node-2 into the D5 location,
    * Installing new FDS (Fire Detection & Suppression) Panel & jumper P-clamps,
    * Preparing the T2 rack hardware, including central rack brackets, in Node-2 for installation, and
    * Accessing the D5 location and replacing port & starboard deck central rack brackets.


SPDM Commissioning: After yesterday’s start, Canadian robotics specialists are continuing SPDM (Special Purpose Dexterous Manipulator) commissioning activities. These include maneuvering to grasp an RMCT (Robo Micro Conical Tool) with each of its Arms, performing a checkout of the tools using both the primary & backup OTCM (ORU Tool Changeout Mechanism) electronics, and finally remove both RMCTs from the THA (Tool Holster Assembly). The activities will run through tomorrow (9/30). At the end, “Dextre” will be parked with RMCTs in hand, ready to proceed with the planned RPCM (Remote Power Controller Module) removal & replacement planned several months in the future.

Soyuz TMA-16 Update: Preparations continue at the Baikonur/Kazakhstan launch site for the launch of Soyuz TMA-16/20S. The State Commission held its meeting this morning, approving the primary and backup crews for TMA-16 and confirming the readiness of the space launcher system for tomorrow’s takeoff.

(Thursday was posted late)

VTR Installation: After the installation of the new VTR1 (Video Tape Recorder 1) in the MSS (Mobile Service System)/Avionics Rack 2 in the Lab (loc. P5) by Frank De Winne, the machine did not work as expected. Troubleshooting is underway.

T2/COLBERT Treadmill: Yesterday, the crew completed all planned T2 installation steps in Node-2. The remainder of the work was originally scheduled after the docked period, but the crew elected to use their free time to complete the job today. Everything has been going smoothly. ACO (Activation & Checkout) is planned after 18S departure.

Emergency Procedures: Emergency procedures for the special case of nine station occupants, with three Soyuz spacecraft docked, are being finalized in discussions between NASA and Moscow. Written procedures books are already on board, and a final check is required on which of the books pertains to which of the three Soyuz groups, taking into account the specific training received by each in Star City.

Nicole Stott was calling up an update on packing and mentioned several packages of "Huggies" being stored.  I've assumed that items like these were used during EVAs (they're worn by U-2 pilots as well according to their life support) but would appreciate confirmation from those more familiar.  No attempt at potty humor, just trying to understand how things are done in space...

Used in EVAs on ISS, as they last several hours obviously.

Officially titled "Maximum Absorbency Garment" (MAG), they are used during both Russian and US EVAs as well as by both Shuttle and Soyuz crew during launch and re-entry. (The crew are in the ACES and Sokol suits for many hours.)

They also have "Huggies" brand wet-wipes.

In the case of ISS, these are actually the "wet wipes" definition of Huggies.

Red Nose in Orbit Update: Guy and Cirque du Soleil are planning a 2-hour live broadcast on Friday, 10/9, while he is on ISS. It will string together live broadcasts from sites around the world. NASA and Cirque du Soleil have signed a unique MOU for this Soyuz visiting crew. NASA will participate in this broadcast event, supporting video recording on orbit, and helping get the NASA messages about ISS and Exploration integrated into the event and the attendant publicity. It may possibly be picked up by broadcast TV. Information about the webcast is available through this link:

Thanks to all for the responses.  While the wet wipe answer make sense it can not approach the classic NASA-ism designation "maximum absorbency garment."   ;D

I would really like to see why NASA insists on giving incoherent designations to benign objects and activities.  All it does is make the complicated and technical process of spaceflight that much more incomprehensible to the average citizen and reporter--not a good thing in a very tough budget environment when NASA desperately needs all the support it can get.

It is functional, descriptive and doesn't change as brands or designs change or is culturally dependant.  While it might be nice for the general public, it is not optimal for those who use it day in and day out.  It is like the names of modules - pure PR; no one at NASA uses them because they are meaningless and confusing.  Sorry, but that is the way it is.

Science Activity Milestone:  For the first time, there are seven simultaneously active NASA payload racks aboard ISS, growing to 11, possibly 12 racks this week. As part of early utilization, over 400 experiments have been conducted on the ISS (all partners), i.e., over 9 years of continuous research.

Soyuz TMA-14/18S Descent Training: Padalka, Barratt & SFP Laliberté spent three hours in the TMA-14 Descent Module (SA) to conduct the Soyuz descent drill, a standard training exercise for every crew returning on a Soyuz. The exercise, which strictly forbids any command activation (except for switching the InPU display), was supported by a tagup and discussions with ground instructor at TsUP/Moscow via S-band. [The session includes a review of the pertinent ODFs (operational data files), specifically the books on Soyuz Ascent & Descent Procedures, Emergency Descents, and Off-Nominal Situations, crew responsibilities when executing the flight program, visual crew recognition of SUS (Entry Control System) failures, spacesuit procedures, etc., with special emphasis on operations with the Neptune-ME cockpit console. The training uses a Descent Simulator application on the RSK1 laptop. During the actual descent, Padalka, as Soyuz CDR, will occupy the middle couch, with Laliberté in the right seat and Barratt in the Descent Module’s left Kazbek couch. Pending the final State Commission decision at about 3.5h before undocking, 18S return is now expected for 10/11 (next Sunday) at 12:32am EDT (10:32am local) in Kazakhstan.]

Soyuz TMA-14/18S MCS Test: Early in the morning, CDR Padalka & FE-1 Barratt worked in the Soyuz TMA-14/18S for the scheduled testing of the spacecraft’s SUDN MCS (Motion Control System) procedures at 4:49am -5:15am EDT, but they ran into an anomaly when posigrade (forward-pushing) KDU thrusters did not fire when commanded. Normally these thrusters are not used for the retrograde burns required for the undocking, but Moscow has scheduled a second MCS test tomorrow. [The anomaly is not seen as a major problem and is not expected to affect the Soyuz undocking on 10/10 since it does not interfere with the spacecraft’s ability to undock and reenter the atmosphere. If tomorrow’s test results are the same, TsUP-Moscow will make procedural changes.]

Soyuz TMA-14/18S ppCO2 Analyzer: Moscow also reported the failure of the ppCO2 (Carbon Dioxide Partial Pressure) analyzer in 18S, requiring Padalka to install an unused LiOH absorber cartridge in the Descent Module and staying an additional hour in the spacecraft to verify its correct operation. [If successful, this will certify this cartridge for use in nominal Soyuz descents.]

Soyuz TMA-14/18S MCS Update: Early in the morning, CDR Padalka supported a re-test of the 18S SUDN MCS (Motion Control System) with a thruster firing. Again telemetry was not received from one thruster. However, all indications are that the posigrade thruster is completely functional and fired nominally. Preliminary investigation points to a sensor problem – that sensor will be masked. No impact to nominal Soyuz 18S undocking, reentry, or landing operations.
