Humanity Has Always Looked Up At The Stars And Distant

NASA will soon be sending astronauts to Mars, where the gravity is ⅓  of earth's, and this has major implications on the human body. In the 6 months that it takes to travel between planets, the astronauts would be weightless.

Muscle atrophy is the loss of skeletal muscle mass and function that occurs when there is a long period of inactivity of the muscles or defects in motor neuron's (Reilly, Beau 2015). Defects in the motor neurons that stimulate the muscle cause the muscle mass to decrease as proteins that initiate contractions of muscle dissipate. Stimulus is not transferred to the weakened muscle fibers effectively, reducing the contractile force possible for generation from the stimulus. Muscle mass increases upon recovery, as restimulation of the muscle enlarges fiber size, thus a greater contractile force can be generated from the stimulus.

Francesca Araco Have you ever wanted to live on a zero gravity plant such as Mars? According to the Article in the scope article “Would You Move To Mars?” by Lauren Tarshis gives us a whole bunch of reasons why we should/shouldn’t move to mars and how NASA is finding life on other planets. I definitely would not move to mars!There are many reasons why I do not want to move to Mars. Therefore, Mars is a dangerous place,it doesn’t have enough air nor water, and if you were to go outside of your bubble (your house on Mars) you would have to wear a spacesuit.(page 6)

NASA has always had the best equipment available to them when training their astronauts to live in a reduced gravity environment. Now their equipment is being used to help treat and prevent many different sports injuries. The Alter-G anti-gravity treadmill is being implemented in many rehabilitation centers for use as sports injury therapy.

This book has proven to be an enlightening read. It both teaches and inspires. Howard Zinn has offered us a perspective of the real story of American history heretofore unavailable to us – history from the perspective of real people – immigrant laborers, American women, the working poor, factory workers, African and Native Americans.

In the late 1800s the United States in the western hemisphere as a pursuit to contend with European economic, political, and military strategies. Another possibility for imperialism would also have trade between other Countries. The United States was becoming a nation that was yarning for wealth, and seeking the need for advancing their own economy. They United States has corrupted many less fortunate countries for The outset to improve their own lavish.

Ed Regis, in the article "let's Not Move to Mars" states: "crews members are in microgravity for the entire trip, with consequent health problems: your bone mass wastes away" (Regis). Additionally crew members will face mental illnesses. Ed Regis also in "Let's Not Move to Mars" states, " Persistent mechanical noises and vibrations, sleep disturbances, unbearable tedium, trance states, depression, monotonous repetition of meals, clothing, routines, conversations and so on" (Regis). Sending people to Mars would turn them mad before they even got there and would be useless.

The human body contains three kinds of muscle tissue: cardiac muscle, smooth muscle and skeletal muscle; each performs specific tasks to maintain homeostasis – the tendency to maintain a stable equilibrium between interdependent elements, mainly that which is maintained by physiological processes. The primary function of muscle, regardless of kind, is to convert chemical energy to mechanical work, which in turn allows the muscle to shorten or contracts. The muscle tissues observed in this experiment is the skeletal muscle which are usually attached to the skeleton. As a result, contraction of the skeletal muscle moves one part of the body with respect to another.

Will The joy of having less gravity on mars effect the rest of her life? Not only the lack of gravity will be a downside the air there and the weather are hugely important to keep tract of. Jennifer L. Holm Uses Scientific information in her fictional story “Follow The Water”.

twitch muscles. Fast twitch muscles have a fast form of myosin ATP and are very

It can also jeopardize the functional performance when adapting to a novel gravitational environment in an acute phase. Some researches have indicated the changes in manual control, visual performance, spatial orientation and gait control after space flight missions, and the greatest changes usually happen immediately after the astronaut experience gravity transition. Also, it is shown that the longer the time of the flight is, the larger possibility of post flight disturbances

Mars, one of Earth's neighboring planets, has been studied since the beginning of mankind. More recently, however, the United States of America has been considering the human colonization of Mars. A manned mission to Mars is something humans need to pursue, regardless the price. A human colonization on Mars could provide the research to create another civilization outside of Earth, could show us what might happen to Earth in the future, and could provide itself as a space station/planet-to-planet trading port to launch rockets off of. A manned mission to Mars is a controversial subject; however, it should be pursued due to the evidence from past missions, the current evidence being found, and the pros outnumbering the cons.

Some of the astronauts experienced visual impairment as well. Overall, Strickland (2017) indicates in the article that the overall findings suggest long-term space flights cause an increase in cerebrospinal fluid, narrowing of the central sulcus, and an upward shift of the brain. However, further research must be done to determine the duration and significance of these changes. This research on the brains of astronauts is crucial because as humans grow more and more technologically advanced and plan for further space exploration and possible colonization of other planets, it is important to understand the possible effects space flight can have on our brains and bodies.

The calcium and phosphorous is excreted through human waste, causing kidney stones in many cases [3]. The most affected bones consist of the heel, femoral neck, lumbar spine and pelvis. Astronauts spend between 2-5 hours a day exercising to try to decrease this atrophy, but will still experience varying levels of bone and muscle loss [3]. The use of artificial gravity could mitigate this problem, and is currently being researched and designed. Along with bone loss, Astronauts will also experience growth in height, by about 3% [3]. Without gravity, the human spine isn’t weighed down and has room to expand. This causes severe back and muscle aches, and makes exercising harder and more painful. Once astronauts return to Earth, they will return to their normal height [3].

Orwell uses the struggles of animals to overcome a neglectful farmer as an allegorical warning of how a tyrant such as stalin rose out of the russian revolution. Feeding animals was so much of a bother for farmer Jones. Lenin, Trotsky and Stalin by his side, enlightened the Russian peasants of the Marxist dream of communism. While pigs Snowball and Napoleon started a revolution after listening to Old Major’s dream of Animalism. With each dictator on the rise, they worked to validate their new government by, waving flags, singing songs, repeating chants, creating holidays, commemorating events, and erecting statues. The animals used the “Battle of the Shed” and “Beasts of england.” Russia used the October Revolution and “Anthem for the
