Re: Space Medicine
SpaceNut,
Science has the solution:
Humans could breathe out of their buttholes like pigs, and trials will begin this year
Unfortunately, or maybe fortunately- though still having a hard time believing that it would be, this might be a solution to people who would otherwise drown to death in their own blood and mucus from COVID / Influenza / other respiratory infections that damage the lungs.

Re: Space Medicine
SpaceNut,
Science has the solution:
I don't know if this is true 'Science' because it would seem a lot of Good Science had Common Sense. Maybe this is another Freak-Show experiment or a real life example of anal-retentive I had no idea why that expression came to be, excessively heads stuck in book, too orderly without sense and fussy some said mental conflict over toilet-training in infancy, but now thanks to 'Science' we have a real life example of it happening?

The Fascinating Differences Between Men And Women Astronauts In Space
https://www.gizmodo.com.au/2014/11/how- … rent-ways/
NASA and the National Space Biomedical Research Institute have published a new research paper detailing how space flight affects “cardiovascular, immunological, sensorimotor, musculoskeletal, reproductive and behavioural implications” on men and women. Here are the highlights.
Orthostatic Intolerance, or the inability to stand without fainting for protracted periods, is more prevalent upon landing in female astronauts than in their male counterparts. One possible reason for this observed difference in orthostatic intolerance between the sexes is reduced leg vascular compliance, which was demonstrated in bed-rest studies — which is a ground analogue for spaceflight.
Women have greater loss of blood plasma volume than men during spaceflight, and women’s stress response characteristically includes a heart rate increase while men respond with an increase in vascular resistance. Still, these Earth observations require further study in space.
The VIIP syndrome (visual impairment / intracranial pressure) manifests with anatomical ocular changes, ranging from mild to clinically significant, with a range of corresponding changes in visual function. Currently 82% of male astronauts vs. 62% of women astronauts (who have flown in space) are affected. However, all clinically significant cases so far have occurred in male astronauts.
Changes in function and concentration of key constituents of the immune system related to spaceflight have been reported. However, differences between male and female immune responses have not been observed in space. On the ground, women mount a more potent immune response than men, which makes them more resistant to viral and bacterial infections; once infected, women mount an even more potent response. This response, however, makes women more susceptible to autoimmune diseases. It is not clear if these changes on the ground will occur during longer space missions, or missions that involve planetary exploration (exposure to gravity).
Radiation presents a major hazard for space travel. It has been reported that female subjects are more susceptible to radiation-induced cancer than their male counterparts; hence radiation permissible exposure levels are lower for women than men astronauts.
Upon transition to microgravity after arriving at the International Space Station (ISS), female astronauts reported a slightly higher incidence of space motion sickness (SMS) compared with men. Conversely, more men experience motion-sickness symptoms upon return to Earth. These data were however not statistically significant, due both to the relatively small sample sizes and small differences in the incidence of SMS reported by the men and women astronauts.
Hearing sensitivity, when measured at several frequencies, declines with age much more rapidly in male astronauts than it does in female astronauts. No evidence suggests that the sex-based hearing differences in the astronaut population are related to microgravity exposure.
The human musculoskeletal response to gravity unloading is highly variable among individuals and a sex-based difference was not observed.
Urinary tract infections in space are more common in women and have been successfully treated with antibiotics.
There is no evidence of sex differences in terms of behavioural or psychological responses to spaceflight. Analysis of ISS astronauts’ neurobehavioral performance and sleep measures showed no sex or gender differences using the Psychomotor Vigilance Test (PVT) of alertness and Visual Analogue Scales of workload, stress, and sleep quality. Since all all astronaut candidates undergo a robust process of psychological screening and selection, the likelihood of an adverse behavioural health condition or psychiatric disorder is greatly diminished.

New mineral found by Chinese scientists
https://www.moondaily.com/reports/New_m … s_999.html
Chinese scientists have achieved a remarkable new feat in their research of the moon as they have discovered and identified the sixth new lunar mineral.
The China National Space Administration and the China Atomic Energy Authority jointly announced in Beijing on Friday that the new mineral-Changesite-(Y)-was found by scientists at the Beijing Research Institute of Uranium Geology from surface samples returned by the country's Chang'e 5 robotic mission and has been certified by the International Mineralogical Association and its Commission on New Minerals, Nomenclature and Classification.
Changesite-(Y), which falls in the category of lunar merrillite, has become the first lunar mineral discovered and identified by Chinese scientists, making China the third nation in the world, after the United States and Russia, to have achieved such a feat, officials from the two agencies said at a news conference in Beijing.
The mineral, in the form of a single-crystalline particle with a diameter of 10 microns, was manually separated by researchers from more than 140,000 tiny particles and then analyzed through a series of advanced mineralogical methods, according to the Beijing Research Institute of Uranium Geology, one of the major institutes under China National Nuclear Corp.
Li Ziying, chief scientist of lunar sample research at the institute, explained that the discovery of the new mineral will help researchers in their studies on the history and physical traits of the moon.
He said the history of the place where the Chang'e 5 probe landed and collected the samples is much younger than that of the landing sites of previous US and Soviet missions, therefore the characteristics of soil samples from there might be different from the US' Apollo and Soviet Union's Luna samples.

Re: Space Medicine
This is Your Brain on Spaceflight
https://www.universetoday.com/160171/th … aceflight/
When you go to space, it’s going to change your brain. Count on it. That’s because space travelers enter microgravity, and that challenges everything the brain knows about gravity. The experience alters their brain functions and “connectivity” between different regions. It’s all part of the ability of our brains and nervous systems to change in response to changes in the environment, or because of traumatic brain stress or injuries.

Re: Space Medicine
This topic has been quiet for a while.
This post is about a technique that appears to assist in preparation for low pressure atmosphere. The technique involves training with xenon.
The entire subject appears to be causing controversy on Earth, but I thought immediately of it's possible efficacy for helping Earth oriented persons to prepare for an excursion on Mars. The 1/2 Bar agreed upon by most members of this forum would appear to have the capability of meeting the needs of humans and perhaps of animals as well. Whether persons used to 1 Bar would require assistance transitioning to 1/2 Bar seems to be to worth asking.
In any case, here is a link to the report, and a bit of the article:

Innovation or dangerous: Xenon gas use to scale Mount Everest faster stirs debate
Climbers using xenon gas reached the summit of Everest in under five days but critics say the shortcut could lead to dangerous overcrowding and undermine the spirit of mountaineering.By Monica Danielle, AccuWeather Managing Editor
Published May 29, 2025 11:24 AM EDT | Updated May 29, 2025 11:48 AM EDT

A new high-altitude climbing strategy is making headlines and stirring serious controversy in the mountaineering world.
Last week, four British climbers reached the summit of Mount Everest less than five days after leaving London. The group’s organizer, mountain guide Lukas Furtenbach, told The Associated Press that they had inhaled xenon gas during a pre-expedition treatment in Germany.
The gas, along with training in hypoxic tents and use of supplemental oxygen, allowed them to bypass the usual multi-week acclimatization process required for most climbers attempting the 29,000-foot peak.
“This showed that it can work,” Furtenbach told The NY Times, adding that his company plans to offer two-week Everest expeditions beginning next year. “This can be the future of commercially guided mountaineering.”
But others say it could put lives at risk and damage the mountain's future.

Chris Dare, a Canadian climber who summited Everest in 2019, told CBC News that this kind of shortcut could worsen already dangerous overcrowding conditions. “Making the mountain easier to summit will likely attract more climbers,” he said, “exacerbating the already serious overcrowding problem.” That year, 11 people died during the spring climbing season.
Dare also raised concerns about safety and scientific uncertainty around xenon, saying “it just seems very, very risky at this onset, right at the beginning.” He warned that climbers using gas-assisted techniques might overestimate their preparedness and suffer from altitude sickness or worse. “You're not training the traditional way of being on the mountain for a month and a half, two months to acclimatize in the natural environment,” he explained.

Xenon is a rare, odorless gas with medical applications, including use as an anesthetic and to diagnose lung conditions. Some researchers believe it can boost red blood cell production and oxygen-carrying capacity, mimicking high-altitude acclimatization. But experts remain skeptical of its use for mountaineering.
“There’s no science to say that this works at high altitudes for climbers, and there’s no science to say that it doesn’t,” Dr. Peter Hackett, a high-altitude researcher at the University of Colorado, told CBC News. “It’s worth studying, but not because it could help people bag a summit faster.”
Hackett emphasized that Furtenbach’s team also used hypoxic tents and supplemental oxygen, both well-known acclimatization aids, making it misleading to credit xenon alone for the team’s rapid ascent.
Drones can now deliver much-needed supplies on Mt. Everest
This year, drones from Airlift Technology, a drone-mapping start-up, can now deliver supplies including ladders, ropes and medical equipment to climbers on Mt. Everest, the world’s tallest mountain.
Dr. Rob Casserley, a British climber and physician who has summited Everest eight times, said he worries about the psychological risks of skipping the usual adaptation period. “You start putting in people who’ve just come cold turkey out of their normal environment,” he told CBC News. “It will put them at great psychological risk of having some kind of meltdown.”
The Nepalese government is now investigating the climb, Himal Gautam, director of Nepal’s tourism department, told The New York Times. “Using xenon is against climbing ethics.”
The followup discussion I hope will occur in the context of NewMars is whether any acclimatization at all is needed for transition to the Mats Standard Habitat atmosphere of 1/2 Bar. The oxygen level will be the same as on Earth at STP, so perhaps there is no need for acclimatization.
If any studies have been done to test this have been done, this topic would be a good place to post links.

Re: Space Medicine
This post is about NASA's handling of a medical emergency at the ISS, and the related discussions.
A member of the ISS crew suffered a brief episode of loss of the ability to speak. The decision was made to bring the bulk of the crew home. This was the first time such an evacuation was needed over the lifetime of ISS.

An astronaut suddenly couldn’t speak in space. What does that mean for future missions?
By
Jacopo Prisco
19 hr ago
NASA astronaut Mike Fincke, a member of the SpaceX Crew-11 mission, suffered a medical episode in space. Miguel J. Rodriguez Carrillo/AFP/Getty ImagesFive months into his fourth International Space Station mission, veteran NASA astronaut Mike Fincke was having dinner the day before a routine spacewalk. Suddenly, he found himself unable to speak. The episode in January lasted just 20 minutes and while Fincke felt no pain, he became agitated.
“It was completely out of the blue. It was just amazingly quick,” Fincke recently told the Associated Press.
“My crewmates definitely saw that I was in distress. It was all hands on deck within just a matter of seconds,” he said.
Fincke’s fellow astronauts and a series of emergency protocols kept him safe, but NASA still made an unprecedented move: The agency cut short the SpaceX Crew-11 mission, returning Fincke and three of his fellow astronauts to Earth a month early and leaving the station staffed by only three people. Now, this event might play a role in how future missions are designed.
Jared Isaacman, NASA’s administrator, said in a post-splashdown news conference that the early return was due to a “serious medical condition.” He added that while astronauts receive extensive medical training, there are circumstances in which the option to come home is the best one, and that’s why that possibility is built into the agency’s flight plans.
“This is what we trained for. It’s built in our planning. It was executed very well,” Isaacman added. “We will capture any relevant lessons learned to inform preparations for subsequent missions.”
But as NASA pursues long duration missions farther into space, what if it’s no longer as simple to just come back?
Health issues in space
SpaceX Crew-11 returned to Earth safely on January 15, eight days after the episode — meaning this wasn’t an emergency evacuation, which would have unfolded in a matter of hours. Still, Fincke was the first in over 290 visitors to the ISS to return home early due to a health concern.

NASA hasn’t revealed many details about the incident, which tracks with its usual approach of protecting astronaut privacy and keeping all medical matters confidential. Even when studies analyze specific aspects of astronauts’ health, the research typically doesn’t disclose identities. Fincke later revealed the early exit was due to concern for his health, without disclosing any formal diagnosis, though he told the Associated Press the symptoms were likely space-related.
And while the response to his situation was unique, Fincke is far from the first person to experience a medical issue in space.
The strong forces and the weightlessness experienced during space travel have a variety of effects on the human body. NASA has been studying these effects for over 50 years and groups them into five key hazard areas: radiation, isolation, distance, microgravity and hostile environments. These forces can cause ailments including bone and muscle loss, cardiovascular issues, immune dysfunction and vision impairment.
One key process that weightlessness affects is blood flow. Away from Earth’s gravity, blood and other body fluids are pushed up toward the head from the legs and torso, causing swelling in the upper body. In 2019, a study conducted on 11 healthy astronauts — nine unidentified men and two women with an average age of 46 — revealed that six of them suffered from stagnant or reverse blood flow, one experienced a blood clot and another a partial blood clot.
“The environment of space can be disabling, and the strains of space can impact virtually every aspect of your body,” said Dr. Farhan Asrar, an associate professor at the Faculty of Medicine of the University of Toronto. “Space affects your muscle mass, your bone health. We know that fluid shifts have been causing a lot of issues as well.”
He added that certain blood flow issues could also potentially lead to a temporary lapse of speech. “There is something known as a TIA, or Transient ischaemic attack, which is basically a brief episode of a neurological dysfunction, usually due to the blood flow to the brain being interrupted,” Asrar said. “It tends to resolve by itself and not leave any kind of permanent damage.” TIA symptoms can also include dizziness, confusion and loss of balance.

It’s not clear, however, whether Fincke experienced any additional symptoms or if his condition had anything to do with blood flow. The crew used the space station’s ultrasound machine to assess Fincke, likely with guidance from mission control.
“I think they probably looked to assess the overall function of the heart and perhaps some of the other structures,” said Scott Parazynski, a veteran of four Space Shuttle missions who’s also a physician. “You can assess whether or not there are any blockages or partial obstructions to the carotid arteries. That’s what I would have done, had I been on board.”
Fluid shifts are the cause of other types of conditions that astronauts often experience. One is SANS, or spaceflight associated neuro-ocular syndrome. It manifests as swelling in the back of the eye and loss of visual acuity, and NASA estimates that about 70% of International Space Station astronauts have suffered from it. SANS was one of the subjects of study during the Polaris Dawn mission, a five-day private human spaceflight launched by SpaceX. Isaacman partially funded and served as commander of the mission before taking his NASA role.
Spending more than six months in space comes with other potential health risks, including the weakening and loss of bone and atrophying muscles. Astronauts also experience blood volume loss, weakened immune systems and cardiovascular deconditioning, since floating takes little effort and the heart doesn’t have to work as hard to pump blood.
“Deep space, it has its own set of challenges,” Asrar said. “We’re relatively new to exploring further distances in deep space, we’re learning from Artemis II and kind of taking that further. But we know that the exposure to radiation is an issue — not just duration of exposure, but also the type of radiation which tends to be more penetrating in deep space.”
Astronauts exposed to radiation — high energy particles and atoms traveling at the close to the speed of light — suffer an increased lifetime risk for cancer, central nervous system effects and degenerative diseases, according to NASA.
The early return of Crew-11 for medical reasons was the first in the history of the International Space Station. NASA
Planning for deep space emergencies
NASA handled Fincke’s medical emergency very professionally and in a measured way, according to Parazynski, who added that one of the advantages of the space station’s close proximity to Earth is that a patient can be stabilized prior to committing them to a rather stressful return to Earth.
“Sometimes it’s better to evaluate the patient there, provide them whatever supportive care that they need, and then make your decision whether or not to bring the astronaut home.”
However, future deep space missions would carry an increased number of health challenges. “The ISS has the ability to be in almost 24-hour connection with Earth,” Asrar said. “So if whatever training the astronauts have doesn’t suffice, they can also get expertise from Earth. However, in deep space, we know communication delays can be an issue.”
The Artemis II crew experienced a communications blackout of about 40 minutes as it transited behind the moon. Astronauts on potential future missions to Mars, once at their destination, would need to wait 20 minutes for any transmission to reach Earth, plus another 20 to receive an answer, due to the amount of time it takes for the signal to travel to Earth and back.

One way to manage the problem would be to include a doctor as a crew member, which wouldn’t be too difficult since many astronauts are also physicians. The first American medical doctor to become an astronaut was Joseph Kerwin in 1973, and since then about three dozen NASA physicians have become astronauts. It’s common in other countries, too: Four of the nine Canadians who have flown in space are physicians.
There wasn’t a medical doctor on board the ISS during Fincke’s medical episode, but NASA administrator Isaacman said he doesn’t believe things would have played out differently had that been the case. He did note, however, that when NASA embarks on missions to Mars, having medical professionals on board would be “additive.”
Crews may eventually be able to anticipate and plan for in-space health care, too. For example, NASA stowed “organ chips” on board Artemis II — bone marrow samples from the astronauts to assess the effects of deep-space conditions, including radiation, on human health. The insights gained from the experiment could lead to individualized treatments, such as personalized medical kits, that ease the way for the astronauts to embark on longer missions — perhaps deeper into the cosmos.
The goal is to one day be able to send up organ chips for astronauts selected for deep space missions ahead of time, so crews can prepare for potential health concerns before they become an issue far from home, according to Lisa Carnell, director of NASA’s Biological and Physical Sciences division.

“We like to say, ‘Know before we go.’ It’s that simple,” Carnell told CNN in a prior interview. “Like, how do we know before we send them to ensure that we bring them back healthy and that they’re as safe as can be? And this is such a simple … eloquent way to do that.”According to Parazynski, even after 60 years of space missions there are still mysteries to be unpacked in terms of how the human body reacts to weightlessness and how to bring people back to their full health after a long duration spaceflight.
“Going to space is a sort of accelerated aging process,” he added. “When we start to think about sending astronauts to the moon and Mars for long periods of time, how do we support them when they arrive there? And how do we bring them back safely to Earth’s gravity after a year or more away from home? It’s an exciting time in space medicine to start answering some of these questions.”
