CAPCOM did report that a power cycle of the suspect Node 2 MDM cleared the indications of concern this morning but the cause of the indications is still unknown.

CAPCOM is passing a big picture update

The P1 MDM errors were a data exception. Plan is still to re-enter the USOS tonight with all crew members wearing the masks and filters they did this morning. Two members will enter the USOS with measurement devices and redirect ducting to prevent airflow from the USOS.

Dreger samples will be taken in US nodes 1 and 2 and the US Lab. Any readings over 5 will result in retreat into the Russian segment. Terry and Samantha are the ground suggestions to go forward because they are requesting the Soyuz 40 crew to enter their Soyuz and close but not lock a hatch--I can't make out the Russian designations.

The P1 MDM errors and a RPC trip were both believed unrelated to this mornings issues.

Terry and Butch are the members going forward to take the measurements. Houston is ready for the crew to proceed.

Moscow is re-explaining the plan to the Russian crew who sound very confused

Hatch opening coming up. MCC-H warns the crew that USOS is slightly higher pressure, so equalizing could take a bit longer than normal. Houston should have internal KU video.

Crew is getting ready to open the hatch into the US segment. Houston cautioned that the US segment is at a higher pressure than the Russian segment and for the crew to be prepared for that. All available camera views have been routed to the ground so the Butch and Terry will have full coverage

Targeteer, thanks for the running commentary. Much appreciated.

Comm should be interesting with the crew wearing masks. Brings back bad memories of trying to talk on the phone during "chem" exercises in the Air Force...

Targeteer · « **Reply #91 on:** 01/14/2015 07:07 pm »

Crew is in the lab and no indications yet in Node 2, checking the lab. Crew audio is muffled but readable. Again bad memories...

Views on US Stream are unfortunately exterior only...

Targeteer · « **Reply #93 on:** 01/14/2015 07:11 pm »

no indications after two measurements in Node 2. Crew is go to doff the masks. Yeah.

Ground sounds like they were unprepared for the good news. Discussing what to do next. Sam checked in from the Russian segment that they are not hearing the ground.

Russian crew cleared to doff masks and open the hatches.

Targeteer · « **Reply #96 on:** 01/14/2015 07:16 pm »

Sam asking about cleaning the masks before re-stow. Again flashbacks about signing the inspection log after an all-clear sounded...

Are there any live continuous air sampling devices on the ISS that look for things like ammonia and smoke? You know, like the smoke detectors and CO2 detectors we have in our houses? If they do, what all do they look for?

Finally, assuming that there are such devices, in today's scenario, the one thing that they were missing was an alarm indicating that the actual air had been contaminated, true?

All sounds like things are returning to normal! They'll need to go feed the Dragon.
