Resist Tubule (Mechanisms of Gravity Resistance in Plants From Signal Transformation and Transduction to Response): Today Flight Engineer (FE)-6 Nyberg attached a Plant Experiment Unit (PEU) with plant samples and the Dehumidifier inside the Cell Biology Experiment Unit (CBEF) and then activated the PEU program. After 32 days of growth in the PEU an ISS …
Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions (InSPACE)-3 Experiment Runs: Flight Engineer (FE)-6 Nyberg completed runs 23 through 26 out of a total of 42 runs planned as part of this experiment series. InSPACE-3 studies the behavior of magnetic colloidal fluids which transition to a solid-like state by the formation and cross-linking of …
In Flight Maintenance (IFM) Crew Quarters (CQ) Cleaning – Flight Engineer (FE)-6 Nyberg cleaned the overhead CQ intake and exhaust ducts, fan and flow sensors. This routine maintenance was performed in preparation for the arrival of new ISS crewmembers later this month. Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions (InSPACE)-3 Experiment Runs: FE-5 …
34S Soyuz Undock & Landing: Soyuz 34S undocked from the ISS Mini-Research Module (MRM)-2 bringing Commander (CDR) Viogradov, Flight Engineer (FE-2) Misurkin, and FE-3 Cassidy back to earth. Prior to undocking, the crew performed leak checks on the vestibule, suits, and hatch between the descent module and the habitation module. The undock command, which initiated …
Monday, Sept 9 at 8:18 PM Central Time, a baseball size fragment of a comet entered Earth’s atmosphere above Alabama, moving southwest at a speed of 76,000 miles per hour. At such speeds, fragile cometary material will not last long. Just 3 seconds after hitting the atmosphere, the meteor disintegrated 25 miles above the town …
LAB Robotics Work Station (RWS) Loss of Communication (LOC): Shortly after midnight Friday night the C&C Multiplexer/Demultiplexer (MDM) lost comm with the (primary) LAB RWS. Ground teams performed troubleshooting over the weekend which resulted in 5 failed power cycles, however that was followed by 4 successful power cycles. Preliminary analysis indicates a possible intermittent hardware …
Spinal Ultrasound Scan Operations: Flight Engineer (FE)-6 Nyberg with FE-5 Parmitano’s assistance, performed her second of three Spinal Ultrasound Scan sessions for her stay onboard the ISS. This investigation aims to characterize microgravity-associated spinal alterations during and after spaceflight using in-flight ultrasound. Results from this research will provide data to enhance crew health for long duration …
Node 3 Carbon Dioxide Removal Assembly (CDRA) Air Selector Valve (ASV) 103 Remove and Replace (R&R): Flight Engineer (FE)-3 Cassidy performed an R&R of the Node 3 CDRA ASV. The valve had failed to reach its commanded position (position B) on GMT 214 and 228. Telemetry indicated that the valve had stalled in an intermediate …
H-II Transfer Vehicle (HTV)-4 Departure: This morning FE-5 Parmitano and FE-6 Nyberg finished closing out the Node 2 vestibule by demating all umbilicals to HTV-4. Meanwhile, FE-3 Cassidy depressurized the vestibule between HTV-4 and Node 2 in preparation for the unberth. Commands were then sent to the Common Berthing Mechanism (CBM) bolts to unlatch prior …
Extravehicular Mobility Unit (EMU) Troubleshooting: On Saturday, Flight Engineer (FE)-3 Cassidy and FE-6 Nyberg performed a removal and replacement (R&R) of EMU 3011 condensate water relief valve (item 134) and associated filter. Crew then performed an EMU screening test and discovered that the water crossover anomaly was still present. They then proceeded with the gas …
