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 ...

(Reuters) - A soyuz capsule bringing back three astronauts from the International Space Station, including the first to represent the British government, made a safe parachute landing on the steppe near the Kazakh city of Zhezkazgan on Saturday.
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 ...
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 ...

NASA astronaut Sandy Magnus works out on the Advanced Resistive Exercise Device aboard the International Space Station. Image Credit: NASA. A new study of 13 International Space Station astronauts suggests a combination of strenuous weightlifting-like exercise and careful attention to diet and nutrition can stave off the bone loss long thought by experts to be an obstacle to long missions by astronauts to deep space destinations.. The study of nine men and four women assigned to the orbiting science laboratory between 2006 and 2009 was focused on the addition of the Advanced Resistive Exercise Device in late 2008.. The ARED joined a treadmill, bicycle ergometer and the less physically taxing Interim Resistive Exercise Device as the primary workout equipment used by station astronauts for more than two hours each day to maintain muscle and bone strength in the absence of gravity.. The ARED doubled the resistive force of the IRAD -- up to 600 pounds -- available to astronauts and increased from ...

This is a first step toward preparing for future, beyond low earth orbit flights, study researcher Lakshmi Putcha, of the NASA Johnson Space Center in Houston.. Astronauts may require medications in space to treat minor illnesses, such as aches and pains, motion sickness and sleeping problems. Drugs sent into space are packed into special containers certified for flight and stored in flight kits.. Drugs in space. Astronauts do undergo a period of quarantine before space travel to prevent catching any infectious illnesses prior to their flight, but that doesnt stop them from experiencing some of Earths everyday ailments during a mission.. Currently, medications aboard the International Space Station are replaced every six months to make sure they stay effective, Putcha said.. But scientists wont always have this option as missions travel farther from Earth, for instance, on a years-long trip to Mars, Putcha added. [6 Everyday Things That Happen Strangely in Space].

To evaluate the effects of microgravity on the production of aroma constituents, the OVERNIGHT SCENTSATION™ rose plant with both an unopened bud and a half bloom was sent into the space aboard NASA space shuttle STS-95 for 9 days, from October 29 through November 6, 1998. While the flower was blooming in space, it was analyzed over four consecutive days using IFF’s proprietary Solid Phase Micro Extraction (SPME) method. After returning to Earth on November 6, the information collected in space was analyzed and compared with the data collected from the same type of rose plant on the ground. The comparative results of the space rose and the Earth rose showed a drastic difference in their fragrance molecules. © 2000 American Institute of Physics ...
CAPE CANAVERAL, Fla. †A navigation error forced SpaceX to delay its shipment to the International Space Station on Wednesday, following an otherwise flawless flight from NASAs historic moon pad.. SpaceXs supply ship, the Dragon, was less than a mile from the orbiting outpost when a problem cropped up in the GPS system. The approach was aborted, and the Dragon backed away. NASA said neither the station nor its six-person crew was in any danger.. Just a few hours earlier, Russia successfully launched a cargo ship from Kazakhstan, its first since a failed launch in December.. SpaceX launched the Dragon capsule Sunday from Kennedy Space Centers Launch Complex 39A, out of action since NASAs space shuttle program ended in 2011. Its the same spot where astronauts flew to the moon in the late 1960s and early 1970s. SpaceX has a 20-year lease with NASA for 39A; besides launching station cargo from there, the company hopes to send up astronauts as early as next year.. Everything was going well ...
NASAs Space Shuttle program is officially over. The final flight of the US National Aeronautics and Space Administrations program - a 13-day jaunt by the Shuttle Atlantis to the International Space Station (ISS) and back - touched down today, marking the end of an era for space exploration.. It also marks the end of an era for the small group of life sciences researchers whose mice, bacteria and plants have flown on the orbital spacecrafts. Without any US government-run manned spaceflights planned for the foreseeable future, those in the field of space biomedicine have fewer options for getting their research samples into orbit and back home again. But some scientists are optimistic that the recent completion of the ISS will mark the beginning of a new golden age for biology ex terra.. I dont think space biomedicine is going to go away, says Jeffrey Sutton, director of the National Space Biomedical Research Institute, a Houston-based consortium of NASAs extramural biomedical research ...
As the Expedition Two crew gets settled aboard the International Space Station, American crew members for future space station missions have begun formal training to meet launch dates, beginning in 2002.. The 14 astronauts, six assigned to primary crews and eight assigned to backup crews, will join a corps of expedition astronauts and cosmonauts previously named to the first four International Space Station expeditions. Russian members of these new expedition crews will be formally announced in the near future.. These assignments signal that the space station is ready for long-term operations, said Charlie Precourt, the chief of the Astronaut Office at NASAs Johnson Space Center in Houston, TX. We have an outstanding corps of highly qualified astronauts who will complete assembly and take the station into a new era of scientific research in space.. The Expedition Five crew will consist of astronaut Peggy Whitson (Ph.D.) and two Russian cosmonauts, one of whom will be the mission commander. ...
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 ...
Data collected during two close flybys of Saturns moon Enceladus by NASAs Cassini spacecraft add more fuel to the fire about the Saturnian ice world containing sub-surface liquid water. The data collected by Cassinis Ion and Neutral Mass Spectrometer during Enceladus flybys in July and Oct. 2008, were released in the July 23 issue of the journal Nature. When Cassini flew through the plume erupting from Enceladus on October 8 of last year, our spectrometer was able to sniff out many complex chemicals, including organic ones, in the vapor and icy particles, said Hunter Waite, the Cassini Ion and Neutral Mass Spectrometer Lead Scientist from the Southwest Research Institute in San Antonio, Texas. 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. Our results emphasize the importance of certain signal transducer proteins, which showed higher abundances in cells grown under reduced
The next day was an accomplishment in its own kind when the hatches between Dragon and the $100 billion orbiting lab were opened.. 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 ...

[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 ...

On December 26th, SpaceXs second-to-last Cargo Dragon spacecraft was photobombed in orbit by the shadow cast on Earth by a solar eclipse, likely a little over a week before the vehicle is set to reenter the atmosphere and splash down in the Pacific Ocean.. Cargo Dragon lifted off atop a rare new Falcon 9 booster - B1059 - on December 5th, carrying around 2600 kg (5800 lb) of cargo inside on the flight-proven capsules third launch into Earth orbit. After a quick three-day journey from its parking orbit to the International Space Station (ISS), Dragon was successfully captured by the stations astronauts with a robotic arm and berthed to the orbital outpost, where the crew quickly unloaded its cargo of food, consumables, science, and equipment.. Shortly after liftoff, Falcon 9 B1059 completed its first successful landing - a bit of a surprise ordeal aboard drone ship Of Course I Still Love You (OCISLY) - and the relatively gentle reentry and trajectory should mean that the booster can be turned ...
