Biological Research In Canisters (BRIC) 23: Over the weekend, the crew transferred all four of the BRIC-23 canisters that were actuated last week to the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). Two of the four canisters were transferred to MELFI following a 24-hour growth period and the remaining two canisters were transferred following a 48-hour growth period. The BRIC-23 investigation studies Bacillus subtilis spores and Staphylococcus aureus cells to understand how they respond to the stressful environment of space. Results from this investigation improve the understanding of how microbes adapt to spaceflight, including whether their adaptations change antibiotic effectiveness, which benefits efforts to maintain crew member health. NanoRacks Module 9: Over the weekend the crew completed the second session of the NanoRacks Module-9 experiment by activating, shaking, and deactivating the mixture tubes. The NanoRacks Module-9 experiment is a collection of student research projects utilizing the NanoRacks Mixsticks. Student teams from across the United States design their own experiments using flight approved fluids and materials. The investigation consists of several science experiments flown in a NanoRacks Module on board the ISS. Biological Rhythms 48 Holter Start: Earlier this morning the crew continued the operations phase of the Biological Rhythms experiment by attaching the Digital Walk Holter Electrocardiogram (ECG) and electrodes. The objective of the Japan Aerospace Exploration Agency (JAXA) Biological Rhythms 48 is to study the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. Mouse Epigenetics Maintenance Operations: The crew refilled water in the Mouse Habitat Cage Unit located in the Cell Biology Experiment Facility (CBEF). The Mouse Epigenetics investigation studies altered gene expression patterns in the organs of male mice that spend one month in space, and also examines changes in the deoxyribonucleic acid (DNA) of their offspring. Results from the investigation identify genetic alterations that happen after exposure to the microgravity environment of space. Fluid Shifts: The crew conducted the first Fluid Shifts operation of this session by configuring the Refrigerated Centrifuge for sample load operations, performing body sample collections and stowing the samples in a MELFI. The crew also collected a galley water sample and stowed in the MELFI prior to ingestion of a Tracer solution from the Tracer Syringe. Fluid Shifts is a joint USOS Russian experiment that measures how much fluid shifts from the lower body to the upper body, in or out of cells and blood vessels, and determines the impact these shifts have on fluid pressure in the head, changes in vision and eye structures. Meteor Hard Drive Change-out: The crew removed and replaced the hard drive in the Meteor Laptop located in the Window Observational Research Facility (WORF). The investigation provides the first space-based measurement of meteor flux as well as monitoring of carbon-based compounds. Continuous measurement of meteor interactions with the Earth’s atmosphere could also spot previously unforeseen meteor showers. Habitability Human Factors Directed Observations: The crew recorded and submitted a walk-through video documenting observations of life onboard ISS, providing insight related to human factors and habitability. The Habitability investigation collects observations about the relationship between crew members and their environment on the ISS. Observations can help spacecraft designers understand how much habitable volume is required, and whether a mission’s duration impacts how much space crew members need. “Road To” Extravehicular Activity (EVA): This week begins preparation tasks for the IDA2 EVA currently scheduled for August 18. Today the crew was scheduled to complete the following EVA Mobility Unit (EMU) tasks, but only completed the first three due to scheduling constraints: Remove EMU 3008 from the Fwd EMU Don/Doff Assembly (EDDA) and stow in the Crew Lock (CL). Remove EMU 3006, which was delivered on SpX-9, from the SEMU Launch Enclosure (SLE), install on the Fwd EDDA and configure for on-orbit operations. Configure and install EMU 3005 in the SLE for return on SpX-9. Retrieve EMU 3003 from the CL and install on Aft EDDA. [Deferred] Remove EMU 3006 from Fwd EDDA and install EMU 3008. [Deferred] Potable Water Dispenser Filter Maintenance: The crew R&Rd the PWD filter and cleaned the fan filter areas behind the PWD. This preventive maintenance is required every 18 months. Transition to the Power Management Control Application (PMCA) and Photovoltaic Control Application (PVCA) R5 (PMPV R5) software suite – The X2 PMPV R5 software transition began over the weekend and will continue into Tuesday. PMCA and PVCA R5 contains new software to manage the Li-Ion batteries that will arrive on HTV-6. In addition to the PMCA and PVCA updates, there also are updates to the Command and Control (C&C) and Portable Computer System (PCS) software. All software has good health signatures to date.
