Neurocognitive Adaptations for Spatial Orientation and Navigation in Astronauts

Brain Science, 2023
Astronauts often face orientation challenges while on orbit, which can lead to operator errors in demanding spatial tasks. In this study, we investigated the impact of long-duration spaceflight on the neural processes supporting astronauts’ spatial ...

Retrospective analysis of somatic mutations and clonal hematopoiesis in astronauts

Communications Biology, 2022
With planned deep space and commercial spaceflights, gaps remain to address health risks in astronauts. Multiple studies have shown associations between clonal expansion of hematopoietic cells with hematopoietic malignancies and cardiometabolic disease ...

Surveillance for jugular venous thrombosis in astronauts

Vascular Medicine, 2022
Background: Thrombosis of the left internal jugular vein in an astronaut aboard the International Space Station was recently described, incidentally discovered during a research study of blood flow in neck veins in microgravity. Given this event, and the

Radiation Risks in Cis-Lunar Space for a Solar Particle Event Similar to the February 1956 Event

Aerospace, 2021
Solar particle events (SPEs) can pose serious threats for future crewed missions to the Moon. Historically, there have been several extreme SPEs that could have been dangerous for astronauts, and thus analyzing their potential risk on humans is an ...

Long-Duration Space Travel Support Must Consider Wider Influences to Conserve Microbiota Composition and Function

Life, 2022
The microbiota is important for immune modulation, nutrient acquisition, vitamin production, and other aspects for long-term human health. Isolated model organisms can lose microbial diversity over time and humans are likely the same.
