A recent NASA study on 25 astronauts who spent six months on the International Space Station found that while space travel can temporarily affect cognitive functions like processing speed and decision-making, there is no evidence of lasting cognitive impairment or neurodegenerative decline. The study, published in Frontiers in Physiology, provides valuable insights for future deep-space missions, although its small sample size limits definitive conclusions.

NASA has refuted tabloid rumors about the health of astronauts Suni Williams and Butch Wilmore aboard the International Space Station, confirming they are in good health. Speculation arose from photos suggesting Williams appeared gaunt, but she clarified her weight remains unchanged, attributing any physical changes to exercise in microgravity. NASA's chief health officer emphasized that astronaut health is closely monitored, and there are sufficient supplies on the ISS until their scheduled return in February 2025.

Three NASA astronauts, who recently returned from an extended mission on the International Space Station, declined to reveal which one of them was hospitalized for a medical issue after their SpaceX capsule landed. The astronauts, including Michael Barratt, Matthew Dominick, and Jeanette Epps, emphasized the unpredictable nature of spaceflight and its effects on the human body. NASA cited medical privacy for not disclosing details about the health issue.

Three NASA astronauts, who returned to Earth after 235 days in space, were taken to a Florida hospital as a precaution but are reportedly in good health. The astronauts, including Michael Barrett, cited medical privacy laws for not disclosing details about the hospital visit, stating that space flight still presents unexpected challenges. Their return was delayed due to technical issues with Boeing's Starliner capsule and weather conditions. The astronauts shared experiences of readjusting to Earth's gravity, highlighting the physical discomforts of returning to normal life.

A recent scientific report highlights that long-duration space travel causes mitochondrial damage in astronauts, akin to accelerated aging. This damage is attributed to increased radiation and zero gravity, which affect cellular health. The lack of Earth's magnetic field in space further complicates the issue, posing challenges for future space settlements. As private space missions increase, more data on long-term health effects will be crucial to address these challenges.

Concerns have been raised about the health of NASA astronaut Sunita Williams, who appears 'gaunt' after being stranded on the International Space Station (ISS) for 152 days due to a faulty spacecraft. Dr. Vinay Gupta, a pulmonologist, suggests that Williams may be experiencing weight loss and stress due to the high-calorie demands of space living, which can lead to muscle and bone loss. Women, in particular, face greater challenges in space, including higher muscle loss and metabolic rate changes. Despite these challenges, Williams' life is not considered in danger.

A study involving 24 astronauts from various space agencies has revealed that headaches are more common in space travel than previously known, with 22 of the 24 astronauts experiencing headaches during their time aboard the International Space Station. The headaches varied in type and timing, with some resembling migraines and others tension headaches. The study suggests that the lack of gravity during space travel may lead to an increase in intracranial pressure, causing the headaches. This adds to the growing body of research on the effects of space travel on the human body, raising concerns for long-duration space missions.

A new study involving 24 astronauts from the U.S., European and Japanese space agencies who traveled aboard the International Space Station for up to 26 weeks has revealed that astronauts are more likely to experience headaches in space than previously known. The headaches, some resembling migraines and others resembling tension headaches, occurred not only during the first couple of weeks in space but also later, possibly due to different mechanisms. The study suggests that the lack of gravity during space travel can cause nausea, vomiting, dizziness, and headaches, while later headaches could result from an increase in intracranial pressure due to fluid accumulation in the upper part of the body and head. This adds to the growing body of research on the effects of space travel on the human body, with implications for future long-duration space missions.

A recent study by an international team of scientists has highlighted the potential impact of prolonged space travel on the human gut microbiome, emphasizing the increased stress from microgravity and space radiation, including Galactic Cosmic Rays (GCR). The researchers recommend further research to understand the risks associated with the space environment and suggest using the International Space Station (ISS) as an ideal environment for testing the human microbiome response to space radiation and microgravity. They stress the need for additional research to estimate the magnitude of adaptation in microorganisms before crewed deep-space exploration can be realized, as it has the potential to identify potential pathogens and develop strategies to prevent their spread during missions.
