Space Mission Design Lecture 19
What's happening in space:
Elektron Status: The Elektron repair continued today with the installation of the gas analyzer base plate, gas analyzers, H2 lines, filters, purifiers, and valves. The entire complement of hardware was launched on 9 Soyuz. The triol fluid remains in the valve and the valve is still capped. The Elektron remains connected. Following a 1 hour start up to allow the gas analyzer to warm up, the Elektron was successfully activated and configured for 50 amp mode. It was temporarily downgraded to 32 amp mode to allow power consumption for TVIS exercise and then moded back to 50 amp mode. All logic is enabled, so the gas analyzers will shut down Elektron following any off nominal signatures. The crew was instructed to check the temperature of the secondary purification unit every orbit. The unit was powered down just prior to crew sleep.
Extravehicular Activity Mobility Unit (EMU) Pump Removal: Expedition 9 Flight Engineer and Expedition 10 Commander completed removal of EMU 3005 pump rotor on October 19th. The crew took over 80 photos to send to the ground for analysis. The crew reported that the impeller was difficult to turn without excessive pressure, and there was a considerable amount of orange residue present. Ground teams analyzed the pictures sent down and determined that the residue is not out of family to what has been seen on other EMU units on the ground. Tomorrow's activities will consist of the crew cleaning the cup and rotor, taking the residue and particulate samples and stowing the approved items for return. The new pump rotor launched on 15P will be installed following the joint mission in 9S Stage.
Carbon Dioxide Removal Assembly (CDRA): The CDRA remains in single bed operation.
FGB Surface Sampling: Due to crew time to complete the FGB Surface Samples, the crew only sampled Plane 1. If it is determined that the Plane 2 samples are required then additional time will need to be scheduled.
