Impact of space flight on bacterial virulence and antibiotic susceptibility Peter William Taylor School of Pharmacy, University College London, London, UK Abstract: Manned space flight induces a reduction in immune competence among crew and is likely to cause deleterious changes to the composition of the gastrointestinal, nasal, and respiratory bacterial flora, leading to an increased risk of infection. The space flight environment may also affect the susceptibility of microorganisms within the spacecraft to antibiotics, key components of flown medical kits, and may modify the virulence characteristics of bacteria and other microorganisms that contaminate the fabric of the International Space Station and other flight platforms. This review will consider the impact of true and simulated microgravity and other characteristics of the space flight environment on bacterial cell behavior in relation to the potential for serious infections that may appear during missions to astronomical objects beyond low
In todays A Lab Aloft, guest blogger Fred Kohl, Ph.D., International Space Station Physical Sciences Research project manager at NASAs Glenn Research Center in Cleveland, talks about some of the physical science investigations that take place in microgravity aboard the space station.. Extremes are part of exploration, whether youre talking about space travel or probing new areas of discovery to expand knowledge in a given science. So it is appropriate that the extreme environment of the International Space Station provides an ideal location to study physical sciences, from flames to fluids. Removing gravity from the equation aboard this Earth-orbiting laboratory reveals the fundamental aspects of physics hidden by force-dependent phenomena where a fluid phase (i.e., a liquid or gas) is present. Such experiments, which investigate the disciplines of fluid physics, complex fluids, materials science, combustion science, biophysics and fundamental physics, use the stations specialized experiment ...

Scientific research on the International Space Station is a collection of experiments that require one or more of the unusual conditions present in low Earth orbit. The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology. The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector. Research on the ISS improves knowledge about the effects of long-term space exposure on the human body. Subjects currently under study include muscle atrophy, bone loss, and fluid shift. The data will be used to determine whether space colonisation and lengthy human spaceflight are feasible. As of 2006, data on bone loss and muscular atrophy suggest that there would be a significant risk of fractures and movement problems if astronauts landed on a planet after a lengthy interplanetary ...

Heart rhythm disturbances have been seen among astronauts. Most of these have been related to cardiovascular disease, but it is not clear whether this was due to pre-existing conditions or effects of space flight. It is hoped that advanced screening for coronary disease has greatly mitigated this risk. Other heart rhythm problems, such as atrial fibrillation, can develop over time, necessitating periodic screening of crewmembers heart rhythms. Beyond these terrestrial heart risks, some concern exists that prolonged exposure to microgravity may lead to heart rhythm disturbances. Although this has not been observed to date, further surveillance is warranted. The incidence and clinical significance of cardiac arrhythmias during long-term exposure to microgravity experienced on the International Space Station (ISS) or during a prolonged (that is, up to 3 years) sojourn to Mars or on the Moon are a concern for the National Aeronautics and Space Administration (NASA). At present, there are only ...

As humanity plans to soar out among the stars into the vast distances of space, the health effects of leaving the cradle of Earth continue to show consequences that are yet to be totally understood.. The latest look into the bodies of space travelers shows the levels of fundamental proteins change due to weightlessness, as reported by a Russian and Canadian team of scientists in the latest issue of the journal Scientific Reports. Essentially, its like the human bodys immune system fights the lack of gravity out beyond our world, they conclude.. Weightlessness for humans is completely new in evolutionary terms, being an environmental factor our species has not faced during the course of evolution, the team writes. Our results support the hypothesis that adaptation to the conditions of space flight takes place in all of othe major types of human cells, tissues, and organs.. Eighteen Russian cosmonauts on the International Space Station served as the subjects. The all-male group had a mean ...

or let it float away into space? Luckily, so far, no astronauts have died while working on the International Space Station (ISS) with all space-related fatalities happening during launch or landing. But as traveling through space becomes commonplace and we head out on three-month trips to colonize Mars, death in space becomes inevitable.. World-famous mortician Caitlin Doughty - who has made a career out of promoting death acceptance - reckons there are three options for dealing with a space corpse which she outlines in her new book, Will My Cat Eat My Eyeballs?. The ISS is pretty small and stowing a dead body would be logistically tricky Bring the body back to Earth. Caitlin pointed out that if an astronauts body is being returned to Earth, it will have to wait for a return shuttle, so the priority is keeping it cool. Unfortunately, the ISS is small and there is definitely no room for a space mortuary.. On the International Space Station, astronauts keep trash and food waste in the coldest ...
David Clement March 24, 2012. Six astronauts at the International Space Station took refuge in escape pods Saturday as a chunk of space debris whizzed by them.. The U.S. space agency NASA said this is the third time in a dozen years of space station operations that a crew has had to seek shelter because of orbiting space junk and prepare -- if necessary -- to rocket back to Earth.. The Russian space agency said a discarded piece of the Russian rocket Cosmos 2251, launched in 1993, passed within 23 kilometers of the space station.. At that distance, NASA said the astronauts were not at risk, but said it evacuated them as a precaution, in case the debris were to hit. The escape capsules are the Soyuz spacecraft the astronauts use to return to Earth, both routinely or in an emergency.. After the debris passed safely, the astronauts returned to their normal duties. Three Russians, two Americans and a Dutchman are aboard the space station.. Meanwhile, an unmanned rocket blasted off from French Guiana ...
ESA and NASA have tested a communications protocol that will allow astronauts to control robots from space stations orbiting planets or asteroids. The test marks the way for a trial-run with an astronaut on the International Space Station next week. Last week a Space Station user centre at the University of Boulder, USA sent a command to a NASA laptop on the International Space Station to start a script that controlled the Mocup robot at ESAs ESOC operations centre in Darmstadt, Germany. The robot was commanded to move forward and take pictures, which it performed as planned. Mocup is one of the robots in ESAs Meteron - Multi-purpose End-To-End Robotic Operations Network - initiative for future missions to the Moon, Mars and other celestial bodies. Space exploration will most likely involve sending robotic explorers to test the waters on uncharted planets before sending humans to land. More.

FreeBookSummary.com ✅. Human Spaceflight: Alterations of the cardiovascular system during parabolic flights and spaceflights The purpose of this research is to identify the changes occurring during parabolic flights and spaceflights, where theres weightlessness. The importance of the cardiovascular system in space, is recognised as well as some of its fundamentals based on past researches. In addition, since parabolic flights are a way of experimenting physiological alterations in the human body, instead of actual spaceflights, the procedure needed for the airbus to reach microgravity conditions is indicated as well.
Major Tom. I agree that the Dkos polls were certainly not scientific or professional.. If you knew that, then why did you use them as evidence that perhaps the American public has already been convinced of something or state that the results are fairly encouraging?. Stop trolling with junk polls and wasting your time or other posters time on arguments supported by flawed statistics. Garbage in, garbage out.. It puzzles me that you slam the space programs of other nations… I didnt. You stated that we should fear any of these countries getting in the front door of space flight as an argument for increased U.S. civil human space flight funding. I pointed out in detail that this is an ignorant argument because those countries that dont have an independent civil human space flight program (Europe, India) are unlikely to have one anytime soon, and those countries that do have independent civil human space flight programs (Russia, China) are making no or very slow progress and are likely ...

The researchers studied sleep architecture in four cosmonauts and one astronaut before, during, and after missions to the Mir space station.. Using the NightCap sleep monitor, they recorded a total of 324 nights of sleep ― 112 pre-flight nights, 83 in-flight nights, and 61 post-flight nights.. Despite having the same sleep opportunity in space as on earth, the astronauts were on average sleeping an hour less each night during the space mission compared to when on earth before or after their mission (5.7 vs 6.7 hours; P , .0001).. In space, the astronauts also spent significantly more time awake in bed, leading to a 17.7% reduction in sleep efficiency.. Sleep architecture was also affected by spaceflight. In space, the time in non-rapid eye movement (non-REM) and REM sleep decreased by 14.1% and 25.8%, respectively. On average, it took about 90 minutes after falling asleep for astronauts to reach their first episode of REM sleep in space ― nearly 1.5 times longer than on earth.. There were ...

Over the last decade, flight surgeons and scientists at NASA began seeing a pattern of visual impairment in astronauts who flew long-duration space missions. The astronauts had blurry vision, and further testing revealed, among several other structural changes, flattening at the back of their eyeballs and inflammation of the head of their optic nerves. The syndrome, known as visual impairment intracranial pressure (VIIP), was reported in nearly two-thirds of astronauts after long-duration missions aboard the International Space Station (ISS).. People initially didnt know what to make of it, and by 2010 there was growing concern as it became apparent that some of the astronauts had severe structural changes that were not fully reversible upon return to earth, said study lead author Noam Alperin, Ph.D., professor of radiology and biomedical engineering at the University of Miami Miller School of Medicine in Miami, Fla.. Scientists previously believed that the primary source of the problem was a ...
Researchers looked at MRI scans from 27 astronauts. Thirteen had flown on the Space Shuttle for a couple weeks, and 14 had spent about six months on the International Space Station. What they found was that the volume of grey matter in the astronaut brains actually decreased.. We found large regions of gray matter volume decreases, which could be related to redistribution of cerebrospinal fluid in space, Rachael Seidler, a professor of kinesiology and psychology at the University of Michigan, said in a statement. Gravity is not available to pull fluids down in the body, resulting in so-called puffy face in space. This may result in a shift of brain position or compression.. But thats not the full story.. They also detected increases in grey matter in the space travelers brains in the regions that are tied to leg movement and sensation. Astronauts, of course, use their legs differently in microgravity than they do down on Earth.. The results are evidence of the brains plasticity- that it ...
MRIs before and after space missions reveal that astronauts brains compress and expand during spaceflight, according to a University of Michigan study. The findings could have applications for treating other health conditions that affect brain function, says principal investigator Rachael Seidler, U-M professor of kinesiology and psychology. The study, believed to be the first to examine structural changes that take place in astronauts brains during spaceflight, found that the volume of gray matter increased or decreased, and the extent of the alteration depended on the length of time spent in space. Seidler and colleagues examined structural MRIs in 12 astronauts who spent two weeks as shuttle crew members, and 14 who spent six months on the International Space Station. All experienced increases and decreases in gray matter in different parts of the brain, with more pronounced changes the longer the astronauts spent in space. We found large regions of gray matter volume decreases, which ...
NanoRacks-Loomis Chaffee School-Effect of microgravity on protein aggregation (NanoRacks-LCS-Protein Aggregation) is a proof-of-concept experiment determining whether or not Hen Egg White Lysozyme (HEWL) aggregation can be induced in microgravity. This experiment yields data regarding protein aggregation kinetics and aggregation conformation in microgravity. Studying the effects of microgravity on lysozyme aggregation, which is similar to aggregation of other neurodegenerative diseases, may yield new discoveries pertinent to the neurodegenerative disease mechanism. Protein aggregation is involved in various neurodegenerative diseases, such as Alzheimers or Parkinsons. By performing NanoRacks-LCS-Protein Aggregation, it is possible that more protein aggregation studies can be realized in microgravity on the International Space Station (ISS). ^ back to top ...

One of the chemicals definitively identified was ammonia ...
Regarding future space exploration missions and long-term exposure experiments, a detailed investigation of all factors present in the outer space environment and their effects on organisms of all life kingdoms is advantageous. Influenced by the multiple factors of outer space, the extremophilic bacterium Deinococcus radiodurans has been long-termly exposed outside the International Space Station in frames of the Tanpopo orbital mission. The study presented here aims to elucidate molecular key components in D. radiodurans, which are responsible for recognition and adaptation to simulated microgravity. D. radiodurans cultures were grown for two days on plates in a fast-rotating 2-D clinostat to minimize sedimentation, thus simulating reduced gravity conditions. Subsequently, metabolites and proteins were extracted and measured with mass spectrometry-based techniques.

Now, the astronauts aboard the International Space Station would be unloading cargo from the first private spacecraft ever to visit the orbiting lab.. There are over 1,014 pounds (460 kilograms) of cargo on the Dragon spacecraft and the unpacking would only begin on May 28. According to NASA flight director Holly Ridings, Monday and Tuesday are very big cargo days on the space station with regard to Dragon. At least one of the crewmembers will be doing cargo operations almost all of their work days those days.. There are currently six astronauts living aboard the station. They include NASA astronauts Don Pettit and Joe Acaba, European astronaut Andre Kuipers, and Russian cosmonauts Oleg Kononenko, Gennady Padalka and Sergei Revin. The unloading would be handled by Acaba and Kuipers which would take a total of about 25 hours.. ...
INTRODUCTION: Astronauts experience alterations in gaze control as a result of adaptive changes in eye-head coordination produced by microgravity exposure. This may lead to potential changes in postflight visual acuity during head and body motion. METHODS: We gathered dynamic visual acuity (DVA) data from 14 astronauts and cosmonauts after long-duration (approximately 6 mo) stays in space. Walking was used to induce self-motion and visual acuity was determined by sequentially presenting Landolt ring optotypes on a computer display placed 4 m in front of subjects. Acuity assessments were made while seated (static condition) and walking (dynamic condition) at 6.4 km x h(-1) on a motorized treadmill. In each condition, a psychophysical threshold detection algorithm minimized the required number of optotype presentations by maximizing the amount displayed around the subject's acuity threshold. The difference between static and dynamic acuity measures provided a metric of change in the ...
The molecular mechanisms underlying muscle atrophy during spaceflight are not well understood. We have analyzed the effects of a 10-day spaceflight on Caenorhabditis elegans muscle development. DNA microarray, real-time quantitative PCR, and quantitative western blot analyses revealed that the amount of MHC in both body-wall and pharyngeal muscle decrease in response to spaceflight. Decreased transcription of the body-wall myogenic transcription factor HLH-1 (CeMyoD) and of the three pharyngeal myogenic transcription factors, PEB-1, CEH-22 and PHA-4 were also observed. Upon return to Earth animals displayed reduced rates of movement, indicating a functional defect. These results demonstrate that C. elegans muscle development is altered in response to spaceflight. This altered development occurs at the level of gene transcription and was observed in the presence of innervation, not simply in isolated cells. This important finding coupled with past observations of decreased levels of the same ...

PHILADELPHIA - Space is one of the most demanding and unforgiving environments. Human exploration of space requires astronauts to maintain consistently high levels of cognitive performance to ensure mission safety and success, and prevent potential errors and accidents. Despite the importance of cognitive performance for mission success, little is known about how cognition is affected by prolonged spaceflight, and what aspects of cognition are primarily affected.. Now, Penn Medicine researchers are poised to help the National Aeronautics and Space Administration (NASA) close this knowledge gap. They have developed a cognitive test battery, known as Cognition, for the National Space Biomedical Research Institute (NSBRI) to measure the impact of typical spaceflight stressors (like microgravity, radiation, confinement and isolation, exposure to elevated levels of CO2, and sleep loss) on cognitive performance. This computer-based test has already been tested by astronauts on Earth. It will be ...

Spaceflight and ground-based microgravity analog experiments have suggested that microgravity can affect microbial growth and metabolism. Although the effects of microgravity and its analogs on microorganisms have been studied for more than 50 years, plausible conflicting and diverse results have frequently been reported in different experiments, especially regarding microbial growth and secondary metabolism. Until now, only the responses of a few typical microbes to microgravity have been investigated; systematic studies of the genetic and phenotypic responses of these microorganisms to microgravity in space are still insufficient due to technological and logistical hurdles. The use of different test strains and secondary metabolites in these studies appears to have caused diverse and conflicting results. Moreover, subtle changes in the extracellular microenvironments around microbial cells play a key role in the diverse responses of microbial growth and secondary metabolisms. Therefore,

by Tachim on September 16, 2017 - 6:08pm On September 14th 2017, Melissa Gaskill who is working at the International Space Station Program Office, wrote an article about how transparent fish called Medaka could help researchers find a solution to the bone density loss of astronauts. This phenomenon is due to the fact that in microgravity, the body does not work as much as when he is on earth. This causes the bone mass to decrease due to insufficient work. To prevent too much bone mass loss, the astronauts need to exercises at least two hours per day and have weeks of rehabilitation.. Now, why use Medaka fish for this experiments? Simply because their transparency helps the researchers target what they are looking for. Secondly the osteoclasts molecular structures are shown to have no major differences between the mamal and the fish, which made these little fishes even more suitable for this experiment.. In order to understand the mechanism behind osteoclasts, a cell that breaks the bone cells in ...

Another book of interest from Penn is Spacetug Copenhagen, book one of the Steps to Space series. I dont know about anyone else, but as a child, I always imagined we would be living on other planets by now (I have an overactive imagination).. This book uses present day engineering and science to show just how close we are to that vision. Its set just fifteen years in the future, has a luxurious hotel in orbit, and judging by the series title, will feature the birth of a space colony.. As with The Dark Colony, its a fascinating (and addictive) read, especially when the source of inspiration is cited as an amateur space program.. The Copenhagen Suborbitals are a non-profit, amateur based space endeavor, funded entirely by private sponsors and donors. They build suborbital space vehicles - designed to pave the way for manned space flight on a micro size spacecraft, and on a micro size budget (Copenhagen Suborbitals). ...

[UPDATE (May 11 at 15:45 UTC): Two astronauts performed an EVA this morning to swap out the ammonia pump suspected of causing the leak. After a successful swap with a spare unit, no more leaking of ammonia snowflakes has been seen, so for now it looks like the problem has been fixed! As I write this they are cleaning up and preparing to go back inside the space station, where they will keep a close eye on the pump and the coolant system to make sure eveything is working as it should.
NASA just appointed a new leader for its human spaceflight program, and hes dead set on making sure the agency puts astronauts on the moon in 2024.
The Spinal Elongation Task completed all its aims, contributing to closure of the HAB gap on microgravity effects on spinal elongation. Study findings were provided to the Constellation Programs Crew Exploration Vehicle (CEV) to aid with the seat design and evaluations, and account for in-space growth adjustments to accommodate crew in terms of clearance, fit, access/reach and seat ingress/egress. Results from this study were also delivered and can be added to the Human Integration Design Handbook (HIDH) in the form of recommendations and guidelines. This inflight activity provided microgravity data on crew anthropometry that could also be used in suit sizing adjustments in space. Further data will need to be collected to determine effect of the personal factors on anthropometric measurements and its trend over time.. ...
The new suit is designed with interchangeable parts that can be configured for spacewalks in microgravity or on a planetary surface. The same core system could be used for the International Space Station, the Gateway in lunar orbit, the Moon, or Mars. The suit could be upgraded for the differences in the Martian environment, including additional technology for life support functionality in the carbon dioxide-rich atmosphere and modified outer garments to keep crew warm in the Mars winter and prevent over heating in the summer season.. A new feature on the improved suit design is the rear-entry hatch. Astronauts will be able to climb into a spacesuit from the back of the suit, which allows the shoulder elements of the hard upper torso to be closer together than the suits currently in use. The improved shoulder placement increases mobility and enables a better fi-t while also reducing the risk of shoulder injuries.. The lower torso, which includes the pants and boots, will be modified from the ...

San Francisco: Even as an investigation into the Crew Dragon engine failure in a test last week has started, finding out the root cause of the problem may take time, a top NASA official has said. The SpaceX Crew Dragon is designed to carry humans to the International Space Station (ISS). The spacecraft completed a successful uncrewed journey to the ISS in March. SpaceX is leading the investigation with active NASA participation, Patricia Sanders, Sanders, Head of NASAs Aerospace Safety Advisory Panel (ASAP), was quoted as saying by CNET.. The investigation will take time before the root cause analysis is completed, Sanders added. The test that saw the engine failure was carried out on April 20. The Crew Dragon capsule suffered an anomaly during ground testing, according to a SpaceX spokesperson. The NASA and SpaceX teams are assessing the anomaly that occurred during a part of the Dragon Super Draco Static Fire Test at SpaceX Landing Zone 1 in Florida.. This is why we test, NASA ...
