Coping in the final frontier: An intervention to reduce spaceflight-induced stress
Psychologica, 2019 Research in human spaceflight has extensively documented how microgravity environments, such as spaceflight across Low Earth Orbit (LEO), affects astronauts’ and Spaceflight Participants’ emotions. However, a more refined understanding of this topic will

Gene expression profiling in slow-Type calf soleus muscle of 30 days space-flown mice [PDF]
, 2017 Microgravity exposure as well as chronic disuse are two main causes of skeletal muscle atrophy in animals and humans. The antigravity calf soleus is a reference postural muscle to investigate the mechanism of disuse-induced maladaptation and plasticity ...

Potential Perturbation of the Ionosphere by Megaconstellations and Corresponding Artificial Re-entry Plasma Dust [PDF]
arXiv, 2023 500,000 to 1 million satellites are expected in the next decades, primarily to build internet constellations called megaconstellations. These megaconstellations are disposable and will constantly re-enter and be replaced, hence creating a layer of conductive particulate.

Histone deacetylase HDA-4-mediated epigenetic regulation in space-flown C. elegans
npj Microgravity, 2021 Epigenetic changes during long-term spaceflight are beginning to be studied by NASA’s twin astronauts and other model organisms. Here, we evaluate the epigenetic regulation of gene expression in space-flown C.

Development of a bedrest muscle stress apparatus [PDF]
, 1979 In attempting further to define the deleterious effects of spaceflight on the human body, measurement systems and techniques were devised to determine the loss of skeletal muscle strength and tone as a result of spaceflight exposure.

Persistent deterioration of visuospatial performance in spaceflight
Scientific Reports, 2021 Although human adaptation to spaceflight has been studied for decades, little is known about its long-term effects on brain and behavior. The present study investigated visuospatial performance and associated electrophysiological responses in astronauts ...
