ISS Daily Summary Report – 1/23/2023


PK-4: A crewmember caught clouds of particles inside the PK-4 chamber using the PK-4 software on the Columbus Module Laptop 1 as part of campaign 15 experiment operations. PK-4 is a scientific collaboration between ESA and the Russian Federal Space Agency (Roscosmos), performing research in the field of Complex Plasmas: low temperature gaseous mixtures composed of ionized gas, neutral gas, and micron-sized particles. The micro-particles become highly charged in the plasma and interact strongly with each other, which can lead to a self-organized structure of the micro-particles: so-called plasma crystals. Experiments in the facility aim to study transport properties, thermodynamics, kinetics and statistical physics, and non-linear waves and instabilities in the plasmas.

Veg-05: The plants growing in the two Veggie facilities were inspected, watered if necessary, and photographed. The Pick-and-Eat Salad-Crop Productivity, Nutritional Value, and Acceptability to Supplement the ISS Food System (Veg-05) investigation is the next step in efforts to address the need for a continuous fresh-food production system in space.


Urine Transfer System (UTS) Offload EDV Swap: Today, the crew swapped the EDV in the offload EDV spot of the UTS. The main objective of the UTS is to provide automated control of urine flow from Toilet System and Waste Hygiene Compartment (WHC) or from external storage containers into the UPA Wastewater Storage Tank Assembly (WSTA).
