Citate:  Station Managers Allow Crew Back In U.S. Segment

Posted on January 14, 2015 at 2:54 pm by .

The International Space Station mission management team, including all of the station Partners, met this afternoon and directed the station’s residents to return to the U.S. segment of the complex before the end of the day, systems permitting. The decision was made hours after the crew members were isolated in the Russian segment following an alarm that could have been indicative of an ammonia leak. The crew is in good condition, was never in any danger and no ammonia leak has been detected on the orbital laboratory. They were informed of the forward plan during their afternoon daily planning conference with flight controllers in Houston, Moscow and the other Partner flight control centers.

Around 3 a.m. Central time today, Station commander Barry Wilmore and Flight Engineer Terry Virts of NASA and Flight Engineer Samantha Cristoforetti of the European Space Agency were directed to don protective masks and move into the Russian segment, closing hatches behind them to the U.S. segment due to the annunciation of an alarm that is part of the environmental systems software on the station designed to monitor the cabin’s atmosphere.  At the same time, the station’s protection software shut down one of two redundant cooling loops (Thermal Control System Loop B).

Data received from a variety of system sources on board have been studied by flight controllers throughout the day and indicate no leakage of ammonia on the station. The alarms this morning that initiated the movement of the crew out of the U.S. segment are suspected to have been caused by a transient error message in one of the station’s computer relay systems, called a multiplexer-demultiplexer. A subsequent action to turn that relay box off and back on cleared the error message and the relay box is reported by flight controllers to be in good operating condition.

As a result, the crew will re-enter the station’s U.S. segment today wearing the same protective masks they donned earlier today and will conduct measurements of the atmosphere to make sure there are no traces of ammonia present. Assuming there is no indication of ammonia, the crew will doff their masks and will remain in the U.S. segment for nominal operations.

Meanwhile, flight controllers are continuing to analyze data in an effort to determine what triggered the alarm that set today’s actions in motion. Work to reactivate cooling loop B on the station will continue throughout the night and into the day Thursday. The crew members are expected to resume a normal complement of research activities on Thursday as well.

Space Station Update

The Expedition 42 crew members are safe and in good shape inside the Russian segment of the International Space Station following an alarm in the U.S. segment at about 4 a.m. EST.

Flight controllers in Mission Control at NASA’s Johnson Space Center in Houston saw an increase in pressure in the station’s water loop for thermal control system B then later saw a cabin pressure increase that could be indicative of an ammonia leak in the worst case scenario. Acting conservatively to protect for the worst case scenario, the crew was directed to isolate themselves in the Russian segment while the teams are evaluating the situation. Non-essential equipment in the U.S. segment of the station was also powered down per the procedures.

In an exchange at 7:02 a.m. with Expedition 42 Commander Barry Wilmore of NASA, spacecraft communicator James Kelly said flight controllers were analyzing their data but said it is not yet known if the alarm was actually

triggered by a leak

or whether the situation was caused by a faulty sensor

or by a problem in a computer relay box that sends data and commands to various systems on the station.

11 January 2015 – “Each time I speak about Simon Wiesenthal, I am asked, “Did you meet him?” Each time I tell the same story.

I was young, he was my hero, I came with
Shimon Samuels (SWC International Relations Director) and with his unique way, Simon Wiesenthal looked at me and just after I said hello, he said: “Don’t be a schmuck and don’t search for Nazis, your generation will have to fight the new forms of anti-Semitism and racism.” I was choked, but this Yiddish word was the best advice ever heard. Simon Wiesenthal knew that troubles would go on.

At the beginning of the 2000’s I went undercover in radical Islam meetings. It was just after the Gulf war. We discovered Hamas branches in Europe but also youth camps to send kids in Yemen, Libya or Iraq.

Shimon Samuels and I made several reports and warnings to European leaders for the Simon Wiesenthal Center. No one helped us or followed us except in France by the Charlie Hebdo staff. Shimon was sued in court; he won after years of battles.

Fourteen years after the anti-Semitic, World Forum, in Durban, 10 years after this story, I cry and shout.

First because of Toulouse, Sarcelles, Creteil, Bruxelles, Ilan Halimi, but also because my family was held in Vincennes in the kosher supermarket.

We were not heard.

So now, we expect actions from Europe and western countries. But don’t worry our tears are already dry, we turn to life and we will never cease to have hope – Hatikva.
