Successful Recovery

Improving safety of space station operations at the time when the near-Earth space is getting increasingly littered with space junk is one of the principal problems in space station design. Along with the measures to reduce the risk of the station pressure shell penetration resulting from a collision with a meteoroid or a piece of space debris that involve protection of the module pressure shells with shields, there is also a need for developing measures and equipment aimed at mitigating catastrophic consequences of the penetration. One of the key factors allowing successful recovery from an emergency situation caused by station depressurization in case of a puncture is the time needed to locate the puncture, which determines possible scenarios for crew actions during recovery operations and their result. The Immediate Puncture Localization System (IPLS) presented in this paper provides reliable and virtually immediate detection of the time and location of the penetration. The proposed concept for the IPLS architecture is based on the use of piezoelectric sensors of acoustic emissions distributed over the inner surface of the pressurized shell of the module that are connected to an electronic unit for processing signals from the sensors. The paper presents the results of studies of the scientific and engineering feasibility of the IPLS operating principles conducted at RSC Energia and TsNIIMash, as well as results of developmental tests on a prototype of such a system in the Service Module of the International Space Station (ISS) in the space experiment Otklik conducted under the Applied Research Program of the ISS Russian Segment. Key words: International space station, ISS Russian Segment, meteoroid, space debris, pressure shell, immediate puncture localization system, piezoelectric sensor, space experiment, high-velocity impact, penetration.

Usability Feedback

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.
