50 Soyuz (50S) Undock: 50S, with Peggy Whitson, Jack Fischer, and Fyodor Yurchikin onboard, undocked Saturday at 4:58 PM CDT and landed in Kazakhstan at 8:22 PM CDT. The ISS will be in 3-crew operations until the arrival of 52S on September 13. Electro-static Levitation Furnace (ELF) Inspection: On Friday, the crew inspected the ELF chamber and removed Foreign Object Debris (FOD) located in the ELF chamber. The FOD will be returned to the ground for additional analysis. ELF activities will resume after SpX-12 unberthing. Miniature Exercise Device (MED-2) Operation Session: Yesterday the crew was scheduled to exercise while using MED-2 body markers and multiple camcorders for ground evaluation. Because the loading strap was fully extended and could not be retracted, the crew completed only the ARED exercise portion of the experiment and ground teams are working on a forward plan to conduct the evaluation portion of the investigation. The ISS’s exercise equipment is large and bulky, while the MED-2 aims to demonstrate small robotic actuators can provide motion and resistance for crew workout sessions, reducing the size and weight of exercise equipment for long-duration space missions. The MED-2 investigation is a system to test key technologies needed to develop space based exercise equipment that may provide appropriate countermeasures to the adverse effects of microgravity. This technology is critical for the initial design and development of second and third generation Counter Measure Systems (CMS) hardware that is an order of magnitude lighter and smaller than existing ISS class of CMS hardware and that has significantly greater reliability. Multi-Omics-Mouse: On Friday, the crew collected blood samples from the mice. Saturday the crew refilled the mice water supply. Today the crew exchanged the waste collecting equipment and odor filter of the Mouse Habitat Cage Unit in glove box, and then transferred the Mouse Cage Units with mice from glove box to Cell Biology Experiment Facility (CBEF). Several studies have reported space flight effects on the human immune system, but the relationship between microbiota and immune dysfunction during flight remains unclear. In the Multi-Omics-Mouse investigation, food with and without fructooligosaccharides (FOS) will be used as prebiotics, to determine if they improve the gut environment and immune function. After the flight, researchers will analyze the gut environment (microbiota and metabolites) and immune system of the mice by multi-omics analysis. Fine Motor Skills (FMS): The crew performed their FMS sessions this morning. The FMS experiment is executed on a touchscreen tablet, where the crew performs a series of interactive tasks. The investigation studies how fine motor skills are effected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity. The goal of FMS is to answer how fine motor performance in microgravity trend/vary over the duration of a six-month and year-long space mission; how fine motor performance on orbit compare with that of a closely matched participant on Earth; and how performance trend/vary before and after gravitational transitions, including the periods of early flight adaptation, and very early/near immediate post-flight periods. Materials Science Laboratory (MSL) Sample Cartridge Assembly (SCA) Removal: This morning the crew was scheduled to remove the SCA from MSL for return and analysis on the ground. However, during yesterday’s Material Science Research Rack (MSRR) activation, the rack came up in an off-nominal configuration. Today’s scheduled activity to remove the SCA was aborted until the issue is better understood. Main Bus Switching Unit (MBSU) Circuit Card R&R Prep: This morning the crew reviewed an overview and procedures associated with the MBSU I-level maintenance planned for later this week to replacing a Common Controller Assembly circuit card. This afternoon the crew will have a conference with ground specialist to address any of the crew’s questions. SpX-12 Dragon Cargo Operations: As of yesterday cargo transfer specialist estimated the crew will require 23 hours to complete packing the Dragon vehicle for return. The crew reported they performed approximately 2.5 hours of cargo operations off the task list today. Today’s Planned Activities All activities were completed unless otherwise noted.
