Earlier this month, NASA announced that it had to cancel a scheduled spacewalk, citing a \u201cmedical situation<\/a>\u201d affecting a \u201csingle crew member who is stable\u201d on board the International Space Station.<\/p>\n The mystery illness eventually led to the space agency staging the first medical evacuation<\/a> in 25 years of continuous operation on board the aging orbital outpost, rushing four astronauts back to Earth in a move that brought the station\u2019s number of occupants from seven to a skeleton crew of just three<\/a>.<\/p>\n While the medical incident only affected a single astronaut, who has yet to be identified for privacy reasons, all four members of the Crew-11 mission cut their time on board the ISS short by weeks, safely splashing down<\/a>\u00a0off the coast of San Diego early Thursday morning. <\/p>\n The four astronauts were airlifted to the Scripps Memorial Hospital<\/a> in San Diego via helicopter for a \u201cplanned overnight stay at a local medical facility for additional evaluation,\u201d according to a January 16 statement<\/a>. After being \u201creleased as expected,\u201d they continued their journey to NASA\u2019s Johnson Space Center in Houston, where they will \u201ccontinue standard postflight reconditioning and evaluations.\u201d<\/p>\n Do you know anything about what caused the evacuation from the ISS? Drop us a line at tips@futurism.com<\/a>. We can keep you anonymous.<\/p>\n \u201cAll crew members remain stable,\u201d the space agency reassured. \u201cTo protect the crew\u2019s medical privacy, no specific details regarding the condition or individual will be shared.\u201d<\/p>\n It\u2019s an exceedingly rare event, highlighting the challenges inherent to providing healthcare in space. While hundreds of miles above the surface, specialized care is hard, if not impossible, to execute. While astronauts undergo rigorous EMT-level training so they can respond to emergencies on board the station, they aren\u2019t full-blown medical professionals, and can only do so much under the direction of doctors back on Earth.<\/p>\n There\u2019s a lot to still learn about providing care during medical emergencies, particularly when it comes to long-duration space exploration missions into deep space. According to a 2022 study<\/a>, there still are plenty of \u201cgaps in knowledge regarding the potential for unanticipated in-flight medical events to affect crew health and capacity, and potentially compromise mission success.\u201d<\/p>\n As researchers from Northumbria University in Newcastle point out in a recent essay for The Conversation<\/a>, medical emergencies are remarkably rare on the ISS, despite being expected to occur on average every three years. Studies have shown that the most common health issues astronauts experience are skin irritation, congestion, disruptions to sleep, and in-flight injuries \u2014 most of which are ironically caused by exercise, which is designed to protect astronauts\u2019 long-term health.<\/p>\n Spending prolonged periods in a microgravity environment has also been shown to affect astronauts\u2019 vision<\/a> and blood pressure<\/a>.<\/p>\n Now that there\u2019s finally been a medical emergency on the station, though, it\u2019s unclear whether the public \u2014 or even the broader medical community \u2014 will ever find out any details. <\/p>\n
