185 DAY IN THE LIFE: PREPARING FOR THE UNEXPECTED CHAPTER 10 is required. As part of the normal process of using the powerful Russian thrusters, the US Solar Alpha Rotary Joints (SARJs) need to be locked into a specific position to prevent structural damage to the large arrays.] SPARTAN: FLIGHT, SPARTAN I’ll need to park my SARJs. FLIGHT: You’re go to park SARJs. ETHOS: FLIGHT, ETHOS. [Looking for a status.] ETHOS: FLIGHT, ETHOS my Lab ITCS is currently trying to transition to dual, I would have expected it to come back up already in Dual by now but that didn’t work. I’m still assessing why that is, but for the crew, it is the ammonia response in 3.3, they’ll be taking readings in the [Russian Segment] and they’ll be reporting that in step 8. If concentrations are high… and FLIGHT I see that warning [an additional red warning alarm appeared on the screen], that’s from the Lab ITCS, that transition didn’t work. I’ll troubleshoot that in a second, but for the crew, they should be calling, like I said, in step 8, their readings. If it’s high basically they’re going to go to step 9 and they’re going to go to the Soyuz and try to establish a clean zone in the Soyuz. If it is low, they’re going to go to step 18, and they’re basically going to try to wait, about 2 and a half hours, until they can scrub all that, and they’ll take continual readings… FLIGHT: Copy. SPARTAN: FLIGHT, SPARTAN, SARJs locked. FLIGHT: Copy, SARJs locked. ADCO: And FLIGHT, ADCO, auto handover to the Russians is enabled. [This means that if the USOS loses the Control Moment Gyro attitude control of the station, the Russian thrusters will automatically take over controlling the vehicle orientation.] FLIGHT: Copy. [FLIGHT confirmed this configuration with the Russian shift flight director on the MCC-M to MCC-H coordination loop. The Russian flight control takes part in the training as well.] CAPCOM [on the S/G-1 loop]: Station, Houston, Space to Ground 1, for a status. FLIGHT: CRONUS, FLIGHT. CRONUS: FLIGHT, CRONUS. FLIGHT: Are public calls good for the crew to call down? CRONUS: Good on the Russian Segment, yes. FLIGHT: Ok. CAPCOM [on the S/G-1 loop]: Station, Houston, Space to Ground 1, for a status. SPARTAN: FLIGHT, SPARTAN, for interface heat exchangers. FLIGHT: Go ahead. SPARTAN: FLIGHT since we cannot determine which side the leak is on I can close both sets of interface heat exchangers. This would remove heat rejection from all modules. [By shutting down the pumps, there will be less pressure potentially pushing ammonia into the cabin since the team is not sure where the leak is located however, this means the thermal loops will not be able to remove heat from the systems.] FLIGHT: Ok. ETHOS: FLIGHT, ETHOS. FLIGHT: ETHOS, FLIGHT. ETHOS: That’s going to remove cooling, like he said, so let me try one more command to go to Single MT, to see if I can pick this back up and determine which side the leak is on. FLIGHT: Alright, so… ETHOS: And if not I think that would be the forward action to bypass those. FLIGHT: Alright, you probably have a minute or so. I don’t want to spend time. CAPCOM [on the SG-1 loop]: Station, Houston, Space to Ground 1, for a status. ETHOS: FLIGHT, ETHOS, I successfully went over to single MT, and I’m taking a look at my data to assess to see where this leak might be. CAPCOM [on the S/G-1 loop]: Station, Houston, Space to Ground 1, status. ETHOS: FLIGHT, ETHOS. FLIGHT: Status? ETHOS: Yes FLIGHT, I swapped over to Single MT, now I have insight into the entire Lab system, its one loop… FLIGHT: Can you confirm by pressures that they’ve closed the hatch between the two segments? ETHOS: Yes FLIGHT let me confirm that. ETHOS: FLIGHT, ETHOS, I cannot confirm that hatch closure between Russian Segment and US Segment right now, the pressures on the Russian Segment are very close to an in-family with the US Segment. FLIGHT: Ok. FLIGHT: All right so ETHOS you see the quantities in the accumulator increasing…
