Blood flow restriction exercise during microgravity exposure in parabolic flight

Experimental Physiology, EarlyView.
Abstract This case report evaluates whether it is possible to perform blood flow restriction (BFR) exercise during exposure to microgravity. The objectives were three‐fold: (1) to determine if a personalised tourniquet system (PTS) hardware technology performs nominally and enables BFR exercise in microgravity; (2) to determine if BFR augments the ...

Assessing Potential Landing Sites With Favorable Illumination and Accessible, Potentially Volatile‐Rich Permanently Shadowed Regions Within Artemis Candidate Landing Regions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...

Simulated Operational Testing of the Prototype Implementation of the SOFIE Model: The 2025 Space Weather Prediction Testbed Exercise

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The CLEAR Space Weather Center of Excellence's solar energetic particle (SEP) model, SOlar wind with FIeld lines and Energetic particles (SOFIE), was run and evaluated on‐site during the Space Weather Prediction Testbed (SWPT) exercise at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (NOAA/SWPC) in May ...

Human hypoxia models in aerospace medicine: Potential applications for human pharmacological research

British Journal of Clinical Pharmacology, Volume 92, Issue 1, Page 58-72, January 2026.
Aerospace medicine required controlled terrestrial models to investigate influences of altered atmosphere conditions, such as hypoxia, on human health and performance. These models could potentially be expanded to encompass disease conditions or treatment targets regulated through hypoxia or hypercapnia.

Hand Exo-Muscular System for Assisting Astronauts During Extravehicular Activities [PDF]

Soft Robotics, 2019
Human exploration of the Solar System is one of the most challenging objectives included in the space programs of the most important space agencies in the world. Since the Apollo program, and especially with the construction and operation of the International Space Station, extravehicular activities (EVA) have become an important part of space ...

Verification of the NOAA Space Weather Prediction Center Solar Flare Forecast (1998–2024)

Space Weather, Volume 23, Issue 10, October 2025.
Abstract The NOAA Space Weather Prediction Center (SWPC) issues the official U.S. government forecast for M‐class and X‐class solar flares, yet the skill of these forecasts has never been comprehensively verified. In this study, we evaluate the SWPC probabilistic flare forecasts over a 26‐year period (1998–2024), comparing them to several zero‐cost and

Space travel in a high-altitude environment: One more step in human BioSpaceForming

BLDE University Journal of Health Sciences, 2018
BACKGROUND: Currently, space programs use sea-level pressures (760 mmHg) and normoxia (21% oxygen fraction) in space capsules. When astronauts need to go for a spacewalk, the pressure has to be reduced to 1/3 that of sea level (240 mmHg).

Analysis of four Apollo 16 double drive tubes using QEMSCAN® mapping techniques: Implications for sampling the lunar regolith in highland terrains

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2504-2523, October 2025.
Abstract The lunar regolith contains a rich history of Solar System impact events and solar activity. Many future missions will land in the south polar region of the Moon, a heavily impact cratered highland terrain, similar to the Apollo 16 landing site.
