50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

open access: yesExperimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

open access: yesExperimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.
