Long-Term Space Flights

We don’t know if there is a disease out in pace that could well be fatal. Being on a long trip to Mars could cause degeneration in muscles, bones, and your heart. Astronauts also need a bunch of exercise as well. Without it, he/she is likely to experience heart problems because it would be too weak to return to Earth’s gravity. Lastly, there is a LOT of radiation exposure in space. Gary Marin, director for advanced programs at the U.S. National Aeronautics and Space Administration said, “Being away from the Earth for three years would mean every cell of your body would be transversed by a galactic ray, and we just don't know what that would do to people." All these health risks add up to an astronomical danger. We need to test how our body reacts to long trips in space before we take take the big leap for

The brain is often exposed to various disturbance during the perioperative period in all age groups. Neurobehavioral disturbances during the perioperative period may manifest as:

MRI uses the body’s natural magnetic properties to formulate an image of the soft tissues. It does this by using the hydrogen atom nucleus which has a single proton and is a spinning charged particle. The human body is made up of 70% water, which is hydrogen and oxygen. Those hydrogen nuclei (protons) spin inside the body, creating their own magnetic field. They are orientated randomly and cancel each other out when no field is applied.

Over the years, brain surgery has evolved substantially. Looking into multiple types of surgery, surgery is able to be quite unusual. Humans will cut into each other a lot of times in order to get rid of deadly disease and even just to remove excess body fat. The reality that we do not marvel about these on a daily basis shows how advanced surgery has grown over the years. Surgery is a safer and more reliable tool including a necessary component of health care. Previously, the surgeries themselves were brutal from lack of understandings toward anesthesia and none of the tools accessible today with operations forced and traumatic. With the present tools through surgery, brain surgery has changed greatly. This article chosen was aligning with

The thought of traveling to another planet has always been so intriguing. Imagine, being light years away from this rather small planet in comparison to others in our same solar system. Living in space would be a completely different experience than living here on

Even if an individual does not experience any obvious structural changes, alterations in cerebral blood flow, neuronal activity, and neurotransmitters can still be apparent.1

Examining the long-term effects of Traumatic Brain Injuries (TBI) are one of the many areas of brain behavior relationships neuropsychologists focus on. Consequently, studies review the effects obstacles have when attempting to remediate coping following TBI (Krpan, K. M., Anderson, N. D., & Stuss, D. T., 2013) while other studies have looked at the relationships between development in children who have suffered from TBI (Ganesalingam, K., Yeates, K. O., Sanson, A. and Anderson, V., 2007). In a highly specialized study, researchers discussed the sex differences in orbitofrontal connectivity in male and female veterans with TBI (McGlade, E., Rogowska, J. & Yurgelun-Todd, D., 2015). Nevertheless, while these studies are examining different ways TBI are influencing different behavioral changes in all ranges of people, they all focus on specific brain behavior relationships. The further purpose of these studies is to determine the best rehabilitation methods to achieve the highest possibility of cognitive functioning. Through the examination of how TBI effect certain areas of the brain, this will allow neuropsychologists to focus rehabilitation efforts specifically on the areas with the most concentrated brain damage.

What happens when you go into space? You lose muscle and bone mass. I found that the astronauts set apart two and a half hours each day are devoted to fitness. If astronauts are not exercising they start losing the bone and muscle that they need. Bone and muscle loss mean decreased size and strength, and can reduce the ability to do the work that they have due the weakness. Once they land on Earth walking difficult by the lose of muscle. Muscle can be built back up with exercise, but when you lose bone is not easy to get back. In the Apollo mission there wasn't room for the exercise equipment that the space station has.

Do you really think that Neil Armstrong can just wake up and go take the first steps on the Moon. Well, the answer is “No”. The training for the Space Race is more important than the actual moon landing. Other people think that the moon land revolutionized space and how we think about it. Although the moon landing was a “Leap for mankind”, I believe that it isn’t even the most important aspect of the Space Race. To begin with, the astronauts need to go through specific training, physically and mentally. They even take classes for medical emergencies. Consequently, they needed to be in peak shape to be on a spaceship so they all went to bed early and ate strict meals. Furthermore, going into space causes sickness and disease. People who go

Not just does space travel affect the body, but it also affects the mind. Sometimes when astronauts come back from space they have space madness. Even though astronauts will face serious health dangers, some people think humans can make better explorations than

Introduction: Long duration human space flight missions are next big thing in space that have capture our imagination for years. Highly sustainable habitats are necessary to support long duration human space flight missions as it impractical to re-supply logistics (Shaw and Weck, 2014). At the time when national space policies have given top priority to human space flight missions, study of closed loop habitats are essential. Thus, it is essential to review development in this area and discuss various issues related to political, technical, engineering, economic aspects of closed loop life support systems.

This is a term describing the damaged brain after being exposed to the space radiation. The text of “Mars-Bound Astronauts Might Fall Victim to ‘Space Brain’” states “...they found brain swelling and permanent damage to communication networks between brain cells. The rats and mice lost their ability to master easy tasks pointing toward deficits in learning and memory.” This was the result of placing rats and mice under the same condition as a human in space. The results of the experiment would be same for the humans. If humans colonized Mars and settled in there, then their brain would be damaged badly permanently. They can lose their memory, have difficulty processing information, can’t do tasks easily as well as expressing thoughts and understanding others. This could affect their ability to work and the relationships between friends and family. Basically, if everyone was settling there, they would lose their healthy strong minds in return of a broken brain, which is causing themselves at risk. Colonization in space for this result is not worth it because of getting “space

There is also a huge risk of the spread of sickness because astronauts live in such close quarters. “During space travel, exposure to microgravity, radiation, and stress alter human immunoregulatory responses, which can in turn impact an astronaut’s ability to prevent acquisition of infectious agents or reactivation of latent infection. In addition, microgravity affects virulence, growth kinetics, and biofilm formation of potential microbial pathogens.” (Mermel, 2013) This just shows some of the possible risks astronauts may encounter during a prolonged space flight such as one to the moon or another planet. Because of all these risks NASA has created an extensive screening process and materials to help counter the spread of disease and infection in a space craft. These advances not only help astronauts but they also have applications for us on earth. We have already seen many of these “spin off” technologies like the implantable pacemaker, Lasik eye surgery and the MRI and CAT scan.

This career requires extremely specific health standards each trainee must meet to become eligible to go on a mission. The space physical is extremely similar to the military flight physical except for a few differences. The vision of the trainee must have a visual acuity of 20/200, or must be correctable to 20/20 in each eye. For every crewmember, extensive amounts of medical test are run before take off due to the high-risk situations encountered in this career. A blood pressure of 140/90 is considered impeccable for anyone aspiring to achieve the status of an astronaut. However, any slight variation in this number is considered a medical
