The goals and objectives of space experiment Control to study parameters of the induced external atmosphere of the Russian Segment of the International Space Station are presented. The processing and analysis procedure for telemetry data obtained using scientific equipment Indicator - ISS is described. Numerical calculations were performed by direct statistical modeling of the flow around the pressure sensor by incoming flotation the Earth's outer atmosphere in the background measurement conditions, as well as in disturbed conditions with two vernier engines of the Zvezda module being operated. A correction function of the pressure sensor is obtained depending on the orientation, temperature factor and selected model of interaction of incident flow molecules with the internal and external device surfaces. The results of numerical modeling of the jet discharges of the the Zvezda vernier engine were compared with the data obtained in full-scale pressure measurements in experiment Control. Key words: pressure sensor, orbital station, induced external atmosphere, direct statistical modeling method.

The paper discusses the process of integrating scientific equipment into the Russian Segment of the International Space Station (ISS RS) to conduct space experiment using the ISS IS information and control system. The paper addresses the stages in ground processing of scientific equipment that are critical for its successful operation after delivery to the ISS RS: tests on the hardware (vibration and hydraulic tests, electromagnetic compatibility tests, incoming inspection), development of the software for the equipment using ground debugging facility and conducting integrated tests in the checkout facility. It points out the need to update the existing stages of ground preparations for experiments to reduce the hardware ground processing time. Taking as examples the space experiment Terminator and experiments conducted using cargo transportation spacecraft Progress, the paper resents results obtained through the use of the described approach. Key words: information and control system, scientific equipment, space experiment, International Space Station, logistics spacecraft Progress, microgravity.

The study introduces a method for determining the characteristics of long-period oscillations of the International Space Station structure by analyzing the displacement of the sighting axis of scientific equipment relative to the calculated position when observing the Earth’s surface from the Russian segment. The technique makes it possible to identify long-term oscillations through noise caused by high-frequency oscillations and measurement errors, as well as long-term trends associated with a change in the orientation of the station. The work was carried out as part of the first stage of the Pelican space experi-ment to develop the technology of wireless energy transmission in space. After processing the measurement results performed in the experiment sessions, it was possible to determine the maximum values of the amplitudes and angular velocities of the displacement of the sighting axis in order to clarify the requirements for the guidance system of scientific equipment used in the subsequent stages of the experiment.

The scientific equipment «Plasmakrystall–4» («PK–4») is designed to study complex (dusty) plasma under microgravity conditions aboard the International Space Station (ISS) and is a joint project of the European Space Agency (ESA) and Roscosmos. Scientific equipment «PK–4» is integrated into «European physiological modules» (EPM) rack, in the European laboratory module Columbus. Experiment control — automated, software-interactive, or manual from an on-board laptop and/or from a terminal in the ground control center. A low-pressure direct current discharge in noble gases in a glass tube is used to create a plasma at scientific equipment «PK–4». Microparticles of a given size are injected into the discharge to obtain a complex plasma. Two digital video cameras allow to trace individual microparticles inside the tube in phase space, which makes a complex plasma to be a good model for studying classical phenomena in condensed matter at the kinetic level. To monitor the plasma conditions, an integrated spectrometer and another video camera are used allowing to observe the plasma's own emission at different wavelengths. To study the reaction of microparticles to external forces, they can be exposed to radiation from a powerful laser, a gas stream, and also to thermophoretic force, i.e., by producing a given temperature gradient. Key words: complex plasmas, microparticles, soft matter, laser manipulation, microgravity, viscosity measurements, gas discharges, plasma diagnostics.

INTRODUCTION: There are knowledge gaps in spaceflight pharmacology with insufficient in-flight data to inform future planning. This effort directly addressed in-mission medication use and also informed open questions regarding spaceflight-associated changes in pharmacokinetics (PK) and/or pharmacodynamics (PD).METHODS: An iOS application was designed to collect medication use information relevant for research from volunteer astronaut crewmembers: medication name, dose, dosing frequency, indication, perceived efficacy, and side effects. Leveraging the limited medication choices aboard allowed a streamlined questionnaire. There were 24 subjects approved for participation.RESULTS: Six crewmembers completed flight data collection and five completed ground data collection before NASA’s early study discontinuation. There were 5766 medication use entries, averaging 20.6 ± 8.4 entries per subject per flight week. Types of medications and their indications were similar to previous reports, with sleep disturbances and muscle/joint pain as primary drivers. Two subjects treated prolonged skin problems. Subjects also used the application in unanticipated ways: to note drug tolerance testing or medication holiday per research protocols, and to share data with flight surgeons. Subjects also provided usability feedback on application design and implementation.DISCUSSION: The volume of data collected (20.6 ± 8.4 entries per subject per flight week) is much greater than was collected previously (<12 per person per entire mission), despite user criticisms regarding app usability. It seems likely that improvements in a software-based questionnaire application could result in a robust data collection tool that astronauts find more acceptable, while simultaneously providing researchers and clinicians with useful data.Wotring VE, Smith LK.
