ISS Daily Summary Report – 1/25/2023


PK-4: The PK-4 HD was packed for return and two new hard drives were inserted. The chamber gas insert valve was switched from Neon to Argon. 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.


Acoustic Monitor Data Transfer: The crew transferred data from Acoustic Monitor to a ZBook Space Station Computer (SSC) for downlink. Acoustic monitoring is an important part of the noise control process on ISS, providing critical data for trend analysis, noise exposure analysis, validation of acoustic analysis and predictions, and to provide strong evidence for ensuring crew health and safety.
