Dragon SpaceX (SpX)-10 Unberth: The crew packed critical items and egressed the vehicle in preparation for Dragon departure. Dragon was unberthed from the ISS via ground commanding at approximately 4:45 PM CST today. Ground teams have started maneuvering the Dragon into a IDA viewing position followed by another maneuver about an hour and a half …
Tracking and Data Relay Satellite (TDRS) 275 Failure: On Wednesday evening, White Sands Facility reported a timeout of the 275 satellite. This resulted in a loss of both S-band and Ku-band communications. The ISS team worked to fill comm gaps where possible. As of Friday, Network Specialists are still troubleshooting the issue with TDRS 275. …
Rodent Research (RR) Habitat Stow: Following Tuesday’s completion of operations, today the crew stowed the RR habitats. The habitats were cleaned and sealed prior to their next use, planned for RR-5 scheduled for SpX-11. Advanced Plant Experiments (APEX)-04 Harvest: The crew removed the APEX-04 petri plate from the Light Microscopy Module (LMM) facility and harvested …
Mobile Servicing System (MSS) Operations: Overnight, the Robotics Ground Controllers unstowed the Robotic Refueling Mission (RRM) Payload from the Special Purpose Dexterous Manipulator (SPDM) Enhanced Orbit Replaceable Unit (ORU) Temporary Platform (EOTP). They then stowed the RRM on the Dragon Trunk Site 1 Passive Flight Releasable Attachment Mechanism (PFRAM). Next they released the RRM and …
2A Direct Current to Direct Current Converter Unit (DDCU) Trips: Today, all of the DDCUs on the 2A power bus tripped off simultaneously due to a bus undervoltage. This included DDCU 2A, DDCU LA2A, DDCU N2P2A, and DDCU N32A. The trip of DDCU 2A removed power from the 2A Pump Flow Control Subassembly (PFCS). Loads …
Rodent Research-4: Over the weekend and continuing today, the crew performed Rodent Research operations, in coordination with ground specialists, collecting samples and stowing them in Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) for return on SpX-10. The Tissue Regeneration-Bone Defect (RR-4) investigation studies what prevents vertebrates such as rodents and humans from regrowing …
Advanced Plant Experiments (APEX)-04: The crew configured the Veggie facility for the next APEX-04 Petri Plate sample for a four-day growing cycle. After the four days of growth, the petri plate will be inserted into the Fluids Integrated Rack (FIR) Light Microscopy Module (LMM) facility for detailed imaging. The APEX-04 (Epigenetic change in Arabidopsis thaliana in response to …
Fluid Shifts Chibis Measurements, Day 1: The 48S crew member performed the first of two days of operations in the Russian Segment conducting the Return minus 45 day (R-45) Fluid Shifts operations. The subject donned the Lower Body Negative Pressure (LBNP/Chibis) device while the operator, with ground support in Moscow, assisted in the medical monitoring. …
Mobile Servicing System (MSS) Operations: Overnight, Robotics Ground Controllers unstowed the Stratospheric Aerosol and Gas Experiment (SAGE) Instrument Panel from the SPDM Enhanced Orbital Replacement Unit (ORU) Temporary Platform (EOTP) and installed it on the SAGE Nadir Viewing Platform (NVP). They then maneuvered the SSRMS to support surveys of the SAGE IP, the EXpedite the …
