Articular cartilage loss is an unmitigated risk of human spaceflight [PDF]
npj MicrogravityMicrogravity and space radiation are hazards of spaceflight that have deleterious effects on articular cartilage. Since it is not widely monitored or protected through dedicated countermeasures, articular cartilage loss is an unmitigated risk of human ...

Impacts of spaceflight experience on human brain structure [PDF]
Scientific Reports, 2023 Spaceflight induces widespread changes in human brain morphology. It is unclear if these brain changes differ with varying mission duration or spaceflight experience history (i.e., novice or experienced, number of prior missions, time between missions ...

Estimating medical risk in human spaceflight. [PDF]
NPJ Microgravity, 2022 AbstractNASA and commercial spaceflight companies will soon be retuning humans to the Moon and then eventually sending them on to Mars. These distant planetary destinations will pose new risks—in particular for the health of the astronaut crews. The bulk of the evidence characterizing human health and performance in spaceflight has come from missions ...
