Aerosol Samplers: Today the crew deployed Active Aerosol Samplers (AASs) in Nodes 1 and 3. The battery-powered AASs actively pull in air and collect particles using the principal of thermophoresis. This is accomplished by flowing the sampled air through a large thermal gradient in a narrow channel. During this process, particles are driven to the …
Micro-12: On Sunday, the crew activated all eighteen Micro-12 Group Activation Packs (GAPs) by mixing microbial media and inoculum. Then crew terminated one GAP by adding a microbial fixative to preserve the organism for subsequent ground-based characterization. Today the crew terminated additional GAPs. Micro-12 examines the effects of spaceflight on the physiology of an exoelectrogenic …
Micro-11: Today the crew performed the final two sessions for the Micro-11 investigation. They checked out, configured and calibrated the Micro-11 microscope, thawed samples removed from a General Laboratory Active Cryogenic ISS Experiment Refrigerator (GLACIER), fixed those samples and loaded them into the microscope for imaging. Afterwards, they inserted the samples into a Minus Eighty …
Progress 69P ISS Reboost: This morning at 11:10 AM CT, the ISS completed a 3m 19s reboost using 69P thrusters. The purpose of the reboost was to start phasing for 54S landing and 55S launch in October and increased the ISS velocity by 0.40 meters per second (m/s). External High Definition Camera (EHDC) Preparation for …
Rodent Research-7 (RR-7): Today the crew completed the second of two days of rodent operations for the RR-7 investigation today. Crewmembers performed bone densitometer scans, blood draws, fecal pellet collections, and sampling operations. Following these operations, the crew performed clean-up activities in the Microgravity Science Glovebox (MSG) to prepare the facility for upcoming science. RR-7 …
Rodent Research-7 (RR-7): The crew completed the first of two days of rodent operations for the RR-7 investigation today. Crewmembers performed bone densitometer scans, blood draws, fecal pellet collections, and sampling operations. RR-7 examines how the space environment affects the community of microorganisms in the gastrointestinal tract of mice (also known as the microbiota). It …
Direct Current Switching Unit (DCSU) 3A Power on Reset (POR): Early Saturday, morning DCSU 3A experienced a POR which, due to power balancing during the current high beta period, resulted in a loss of power to some downstream loads. The crew and ground teams worked together to recover from the failure and teams continue to …
Micro-11: Today the crew performed two sessions for the Micro-11 investigation. They checked out, configured and calibrated the Micro-11 microscope, thawed samples removed from a General Laboratory Active Cryogenic ISS Experiment Refrigerator (GLACIER), fixed those samples and loaded them into the microscope for imaging. Afterwards, they inserted the samples into a Minus Eighty Degree Celsius …
Aerosol Samplers: Today the crew retrieved and stowed the sample cartridges from each deployed Active Aerosol Sampler (AAS) and connected the AASs to the battery charger. After the battery charge, the crew installed a sample cartridge and re-deployed one of the AASs in the US Laboratory. The second AAS had not taken a full charge …
AngieX Cancer Therapy: Today the crew performed microscope operations for the AngieX Cancer Therapy investigation. The AngieX Cancer Therapy investigation examines whether endothelial cells cultured in microgravity represent a valid in vitro model to test effects of vascular-targeted agents on normal blood vessels. AngieX has developed a treatment that targets both tumor cells and vasculature, …
