The exact quote from Houston was "...the UPA has lost capability to process urine..." The ability to rewind a Quicktime playback of the station audio is very handy sometimes. 

On a somewhat related note, I really wish the station video feed would include the internal camera feeds as well when available. The outside views are awesome but it would be nice to see what's going on all day--not just during the 1 hour, 5 day a week, PAO commentaries.  Apparently PAO doesn't trust the viewer to figure out what's going on without their "expert" descriptions. Does anyone have an official reason why the internal views aren't available full-time?

Love the site and the incredible insight it gives to the world's space programs...

The internal views were discussed on the original thread here, it's because of privacy and proprietary concerns.

UPA Failure:   On Thursday (4/23) evening, the Urine Processing Assembly experienced a check valve fault for each of four consecutive runs, which appears to be a re-occurrence of the sticky check valve issues previously seen on the UPA.  It had been determined before that the check valve is not required and will be removed.  Since the UPA had lost the capability to process urine and the WSTA (Wastewater Storage Tank Assembly was 70% full, the crew has been directed to use the SM ASU toilet facility through this weekend.  Specialists will convene to determine a forward plan which includes using the WHC (Waste & Hygiene Compartment) in manual mode, and developing IFM (In-Flight Maintenance) procedures to remove the valve.

TVM Update:  Yesterday, TsUP/Moscow ground controllers performed a restart with context of the subset 1 of the Russian TVM (Terminal Computer System) in the SM.  No changes were made to the hardware, software or firmware prior to restart, and the data were recorded.  The TVM-1 failed out of set approximately 1h 20min later.  Further restarts will be attempted in the future after specialists review the data and determine a forward plan.  Meanwhile, TVM is running nominally on two subsets.

Solar Array Characterization Test:   Overnight on 4/22-23, the DTF (Dedicated Thruster Firing) test for structural dynamics characterization of the S4 (Starboard-4) solar array truss was completed successfully by ground controllers.  A similar DTF for the S6 truss is scheduled for next week.

It is my understanding that these units need to be fully operational before the ISS is go for a six man crew. Does anyone know what the go/no go cutoff date is?

Special Maneuver Strategy Proposed:   Refueling the FGB tanks from Progress 32P is completed.  Cabin air repress from 32P is on schedule for 4/29.  Progress 32P will remain active through 5/4 for roll control (around ISS longitudinal axis).  That results in a special strategy for DAM (Debris Avoidance Maneuvers):  32P would be used for any DAMs between now and 5/4.  From then until 5/14, Soyuz thrusters will be available for a required DAM.  Recommendations for Flight Rules and OIP procedures will be provided by Moscow for joint IP (International Partner) review and approval on 4/28 & 4/29.

Potable Water Consumption Status:   Based on extensive sample analyses, ground experts have declared the processed water from the PWD (Potable Water Dispenser) to be fit for crew consumption.  Before the crew can drink the water, one larger flushing remains, in order to wash out the iodine remaining in the PWD filter from the “shock” iodination treatment during 15A.  The activity will be scheduled in the next few days, after which the formal Go will be given for PWD consumption.  The daily use of the PWD will preclude the need for the daily microbial 50mL flushes.

The FE-2 changed out the urine receptacle and insert filter in the WHC (Waste & Hygiene Compartment), followed by an activation and functionality test.    [The US WHC is currently not to be used by the crew due to the UPA (Urine Processor Assembly)’s malfunction (stuck check valve between the DA/Distillation Assembly and the WPA/Water Processor Assembly’s waste water tank).  The crew is using the SM ASU toilet facility as before the arrival of the WHC.  The failed valve is obsolete due to a design change, and intrusive maintenance of the UPA will be necessary to remove it.  However, since the valve was not designed for on-orbit removal, engineers have to come up with a way to fabricate a tool on orbit that can be used to accomplish the IFM.]

Official approval for 6 crew came today.  We have enough resources to get through October.

The Apr 30 status report was skipped -- this is the one dated May 1 (and the orbit count indicates it is correct, not a mistaken date).


   Potable Water Usage Update: During the 90-day checkout, a significant number of PWD (Potable Water Dispenser) samples were taken for ground and in-flight analysis. The hot water had consistently zero microbial readings. Product water from WRS (Water Recovery System) showed consistently very low or zero indications. The ambient-temperature line was consistently above the medical requirement of 50 cfu. A 40 ppm iodine shock was implemented to reduce level of colony count. Three strains of microbes were found in the ambient leg that are usually found in municipal water systems, none of which are pathogenic. The medical limit number is an “alert limit” to trigger analysis to consider total bacterial count, negative coliforms, and pathogenic status. With the results obtained, specialists are recommending oral consumption even though the results exceed the med limit. At this point, CSA, ESA, JAXA, and NASA are go for PWD potable use, but the Russian medical specialists are not ready yet for making a decision. The waiver issue will be revisited early next week, as will the waiver of iodine monitoring.

I have a bootleg copy of the still unposted apr 30 status report if anyone needs it -- nothing special in it, just some bookkeeping oversight in the URL change, probably.

MEDIA ADVISORY: M09-075

NASA CONNECTS ATLANTA STUDENTS TO ASTRONAUTS ON SPACE STATION

WASHINGTON -- Students from the Ronald E. McNair Discovery Learning
Academy in Atlanta will participate in an out-of-this-world learning
experience on Wednesday, May 5, when they receive a call from
astronauts aboard the International Space Station. The downlink will
air live worldwide on NASA Television and also be available on NASA's
Web site. This is the second event of its kind to be held in the
state of Georgia.

A live in-flight education downlink with the crew will take place
between 11:15 a.m. and 11:35 a.m. EDT at the Fernbank Science Center
in Dekalb County. The 20-minute question-and-answer event will
feature astronauts Mike Barratt and Koichi Wakata, who are flight
engineers aboard the Expedition 19 mission to the station.

Students and teachers are preparing for the downlink by visiting the
NASA Web site to learn about the station, crew members, mission
objectives and science experiments. Following the event, students
will engage in hands-on activities, such as a robotic space mission
challenge and rocket building.

NASA's education downlinks support the agency's efforts to encourage
students to study and pursue careers in science, technology,
engineering and math, or STEM. These events, which NASA's Teaching
from Space Office facilitate, use the unique experience of human
spaceflight to promote and enhance STEM education.

Fernbank Science Center is part of NASA's Science, Engineering,
Mathematics and Aerospace Academy program known as SEMAA. SEMAA is a
national, innovative project designed to increase participation and
retention of historically underserved and underrepresented
kindergarten through 12th grade youth in the areas of science,
technology, engineering and mathematics.

"We're excited about this extraordinary learning experience to inspire
SEMAA students' interest in STEM careers," said Jo Ann Charleston,
chief of the Educational Programs Office at NASA's Glenn Research
Center in Cleveland. "Stimulating interest in these disciplines helps
NASA develop the next generation of scientists and engineers who will
take us back to the moon, on to Mars and beyond."
