ISS Daily Summary Report – 5/23/2023

Private Astronaut Mission (PAM) Axiom-2 (Ax-2):

ISS Familiarization, Emergency Overview, and On-Orbit Adaptation: The Ax-2 crew completed all their on-orbit handover/ISS familiarization activities with the ISS PAM facilitator. Additionally, the Ax-2 crew completed the Emergency Roles and Responsibility review with the full ISS crew and completed the Emergency On-Board Training (OBT). Emergency response hardware was installed in the Ax-2 Crew Dragon. The Ax-2 crew also had adaptation time today to adjust to life in orbit.


Confocal Space Microscopy (COSMIC): Checkout Samples were removed from the Thermal Container on the COSMIC Microscope and the protection cover was installed in preparation for future Cell Gravisensing-2 operations. COSMIC is a JAXA facility that provides fluorescence images of biological samples aboard the ISS. Confocal microscopy uses spatial filtering techniques to eliminate out-of-focus light or glare in specimens with thicknesses exceeding the immediate plane of focus. With the Confocal Microscope, data can be obtained on the fundamental nature of cellular and tissue structure and functions in real-time.

Electro-static Levitation Furnace (ELF): The ELF furnace cables were reconfigured to allow the ground to perform a software update. The ELF is an experimental facility designed to levitate/melt/solidify materials by containerless processing techniques using the Electrostatic Levitation method. With this facility, thermophysical properties of high temperature melts can be measured, and solidification from deeply undercooled melts can be achieved. The ELF is located in the Japanese Experiment Module (JEM) Multipurpose Small Payload Rack (MSPR) in the Kibo Module.

Hicari-II: The Hicari-II Sample Cartridge for Run #3 was assembled and installed into the Gradient Heating Furnace (GHF) Sample Cartridge Automatic Exchange Mechanism (SCAM) holder #4. Study of Silicon-Germanium Crystal Growth in Microgravity (Hicari-II) continues work from the Hicari investigation examining the physical properties of Silicon-Germanium (SiGe) crystals. These crystals show promise as a material for making infrared optical lenses and electrical devices, but present challenges including slow growth rate and difficulty controlling impurities. This investigation could help solve those challenges and support development of techniques for growing and using SiGe crystals.

Ring-Sheared Drop-Interfacial Bioprocessing of Pharmaceuticals (RSD-IBP): The RSD set screws within the flexible syringe dispensing motor coupler were tightened in order ensure proper connection. The ground verified a good configuration, and Sample 24 was successfully extruded. The ISS RSD module is a containerless liquid system that makes it possible to study protein solutions without the effects of interactions with solid walls. RSD-IBP studies the behavior of high-concentration protein fluids and tests computer models for predicting that behavior. More accurate models could enable production of next-generation medicines for treating cancers and other diseases.


Regenerative Environmental Control and Life Support System (ECLSS) Recycle Tank Drain/Fill: The crew set up the drain of the installed Recycle Tank to the Brine ЕДВ using the Brine Processor Transfer Hose. After setup, the ground team initiated the drain using the Urine Transfer System (UTS). Following that, the crew terminated the drain of the installed Recycle Tank to the Brine ЕДВ, then repositioned the fill/drain valve to fill. In the next step of the process, the crew swapped the ЕДВ in the offload ЕДВ spot of the UTS. Finally, the crew configured the Urine Processor Assembly (UPA) Fill Drain Valve for UPA processing. The UPA, part of the Regenerative ECLSS System, produces distillate from a mixture of pretreated urine, urine flush water, and Crew Health Care System (CHeCS) wastewater.
