The EMU is an independent anthropomorphic system that provides environmental protection, mobility, life support, and communications for the crewmember to perform an EVA in Earth orbit.Īll activities are complete unless otherwise noted. EMU loop scrubs are required preventative maintenance needed to remove any chemical and biological contaminants from the EMU cooling loop. Finally, crew terminated, deconfigured, and checked out the EMUs. Conductivity readings and a water sample were taken from the cooling loop following the 70-minute scrub. The COTS air sensors are standalone sensors that will measure H 20, CO 2, and O 2 levels on station.Įxtravehicular Mobility Unit (EMU) Cooling Loop Maintenance Scrub: The crew performed ionic and particulate filtration (scrubbing) and biocidal maintenance (iodination) of EMUs 3004, 3003, Hard Upper Torso (HUT) ORU 2036, and A/L cooling water loops. The Node 3 Adlink CO 2 Sensor was already present and was connected to the Urine Transfer System (UTS) Adlink Mini PC. Node 3 Commercial Off-the-Shelf (COTS) Air Sensors Install: The crew installed the COTS air sensors (O 2 Trending Sensor, Adlink CO 2 Sensor, RH Trending Sensor) in the Node 3 module. Any areas of interest were photographed for analysis on the ground. This was performed on the Forward, Nadir, and Starboard Node 3 hatches, the PMM, the Port and Starboard Airlock (A/L) hatches, the Zen Japanese Experiment Module (JEM) Pressurized Module (JPM) hatch, and the JEM Experiment Logistics Module – Pressurized (JLP) hatch. Hatch Seal Inspection: Today, the crew cleaned and inspected the hatch seals, hatch plate sealing surface, crank handle mechanism, hatch seal interlocking joints, and Permanent Multipurpose Module (PMM) hatch kicker pins for damage or foreign object debris (FOD). Frequency of MCA ORBICRAFT-ZORKIY 437.850 MHz GMSK 2k4 USP FEC, GMSK 4k8 USP FEC, GMSK 9k6 USP FEC, SSTV Telemetry of the MSC ORBICRAFT-ZORKIY Conditions: within 6 days, the satellite will broadcast 6 (six) different images in Robot 72 mode.

The PPSA is a UPA upgrade that combines the Pressure Control and Pump Assembly (PCPA), Separator Plumbing Assembly (SPA), and Purge Gas 20 Micron Filter into a single Orbital Replacement Unit (ORU).
IFM Ku-Band Power Supply Install: Today, the crew installed a Ku-band power supply at NOD3A3 with two power cables as a get-ahead task for the future installation of the Purge Pump and Separator Assembly (PPSA) in the Urine Processing Assembly (UPA). The Z1 dome is largely used for cargo operations. The crew was able to push the crank handle and open the hatch.

As part of the troubleshooting, the crew removed the hatch Manual Pressure Equalization Valve (MPEV) and set up an endoscope that was fed through the removed MPEV hole to survey the EV side of the hatch. In-Flight Maintenance (IFM) Node 1 Zenith Hatch Troubleshooting: Today, the crew performed troubleshooting on the Node 1 Zenith Hatch, which the crew had been unable to open earlier this year to access the Z1 Dome.
