Acoustic Diagnostics: The crew reviewed the big picture words for the upcoming Acoustics Diagnostics investigation. The Acoustic Upgraded Diagnostics In-Orbit (Acoustic Diagnostics) investigation tests the hearing of ISS crew members before, during, and after flight. This study assesses the possible adverse effects of noise and the microgravity environment aboard the ISS on human hearing. The investigation compares the relationship between the detection of otoacoustic emissions, sounds naturally generated from within the inner ear, and hearing loss levels when exposed to noisy environments.
Biofabrication Facility (BFF): Following the successful execution of the corrective procedure earlier this week, the crew performed the cassette installation/removal and the syringe swaps in support of the first science print with cells. If successful, the printed tissue will remain in the BFF for a period of time, then be transferred to the thermally-controlled ADSEP (ADvanced Space Experiment Processor). Using 3D biological printers to produce usable human organs has long been a dream of scientists and doctors around the globe. However, printing the tiny, complex structures found inside human organs, such as capillary structures, has proven difficult to accomplish in Earth’s gravity environment. To overcome this challenge, Techshot designed their BFF to print organ-like tissues in microgravity, acting as a stepping stone in a long-term plan to manufacture whole human organs in space using refined biological 3D printing techniques.
Fluid Science Laboratory/Reference mUltiscale Boiling Investigation (FSL/RUBI) Reconfiguration: In preparation for the upcoming investigation, the crew performed the RUBI harness configuration and installation. Some difficulties were encountered installing the cables and the ground team is discussing if the current configuration is suitable. Nucleate boiling is a process that is used in many technical applications of heat transfer. Examples are power plants and reactor technology, air conditioning technology as well as chemical and process engineering. The design of new processes and evaporators is significantly hindered by the fact that general methods of calculation are not available yet. The development of such methods requires a better understanding of highly complex and dynamic transport phenomena.
Multi-purpose Small Payload Rack (MSPR) Reconfiguration: The crew performed a test sample removal and reconfiguration of the Fluorescence Microscope. The MSPR is a multipurpose payload rack system used in the JEM. It has two workspaces and a worktable that can be used for wide fields of space environment utilization including science and educational missions.
SPHERES Zero Robotics Dry Run and Competition: The crew supported the dry run and student competition for the 2019 middle School Summer Program. The completion went very well and numerous tests were successfully performed. The middle school teams could be heard cheering several times in the background. The premise of this ZR session is for one SPHERES satellite to retrieve a damaged SPHERES satellite from a virtual debris field in low Earth orbit. ZR allows middle school and high school students develop code to achieve the goals of the competition. The algorithms are tested by the SPHERES team and the best designs are selected for the competition to operate the SPHERES satellites on board the ISS.
Extravehicular Activity (EVA) Preparations: The crew performed the following preparations for the International Docking Adapter (IDA)3 EVA currently planned no earlier than August 21:
- Completed maintenance cycle on all helmet lights, Pistol Grip Tool (PGT) batteries and Rechargeable EVA Battery Assemblies (REBAs).
- Verified Simplified Aid for EVA Rescue (SAFER) functionality.
- Tool configuration
Compound Specific Analyzer-Combustion Products (CSA-CP) Maintenance: The crew performed this regularly scheduled maintenance to replace battery packs in all CSA-CPs and zero calibrate the units.
