Space Flight: The Dangers of Weightlessness
In the awe-inspiring event of man experiencing interstellar travel many detrimental problems arise. Before 1970, the majority of biomedical studies on space flight were conducted immediately before and after flight. They examined the changes and readaptation processes for astronauts from a weightless to a gravitational environ-ment. After the successful Skylab space station projects from 1973-1974 and the Soviet Salyut missions from 1977-1982, biomedical research and experiments commenced in space. These experiments in space have shown that the physiological aspects can be deadly if not prepared for correctly and adequate medical support is not available. Although problems due to weightlessness and lack of exercise have been thoroughly researched and new machines and procedures have been developed to overcome these difficulties, there is still the opportunity to further understand weightlessness.
The majority of difficulties that arise can be traced back to the zero gravity environment in which humans experience physiological changes which can be detrimental to their health. When humans enter weightless space they become dis-oriented due to the neurovestibular interactions, those that are processed in the brain cavity (DeHart 840). These cause side effects, such as space motion sickness or Space Adaptation Syndrome (SAS) (Shipman, Humans 99). As astronauts enter zero gravity they experience a nauseous sensation which returns with fast actions or movement from a small to a large space in the space vehicle. Those who are more susceptible to this illusory sensation develop space motion sickness and have personalities that are introversive, neurotic, or fearful (DeHart 840-841). Thi...

Space is a world that many have never and will never experience. Those who’ve never explored the galaxies are left with just their imagination as they try to dream what life is like in the endless void. Questions are left unanswered and unexplained as people wonder: How much of this endlessly expanding universe can humans handle when left out there? Mary Roach, who is determined to find the answer, unearths systems that give the opportunity to encounter different incidents in space without leaving Earth. Roach explains the methods space enthusiasts use to realistically simulate events in space as much as possible in her book “Packing For Mars”. The concerns about potential problems when left in a place without gravity and life are addressed

Dell believes in getting feedback from customers and suppliers so as to bring information from the outside world of Dell. By doing this, Dell could stay competitive with other alternative brands. Michael Dell once said he would roam around, outside Dell to observe, analyse and hear how the people in the outside world thinks about their brand as well as the others. He would crash the chatrroms and listen to their conversation about their deliberation on their purchasing behavior. Therefore, he believes by doing this it gives Dell a great opportunity to improve the company.

Weather from population, density, and housing, to other transit, congestion, traffic, and appropriate land use issues, the city of Tempe has a good General Plan that exhibits concern for its citizens, proactive assertiveness, great ambition, and a realistic sense of practicality to help maintain a strong and economically successful community, just as it always has, for years to come.
5. The similarities between detraining and spaceflight are to say the least comparable. The reasons for the effects of spaceflight are even more complex than that of detraining. During flight astronauts go through changes in the muscular strength and mass, similar to that of injured athletes, yet at an even fast rate. The muscles that keep the body upright on earth decline in strength and mass inevitably to allow the body to respond appropriately to microgravity. The rate at which strength and mass are loss again depends on the physical condition of the astronauts and the length of continued exposure to microgravity. The body makes these adjustments in order to meet the demands of microgravity.

The cost of college tuition continues to increase each year. If this keeps increasing the way it has been, students will be indebted the rest of their life. Author of “The Looming Student Loan Crisis”, Jackson Toby states that student loans have increased along with the increase of tuition costs. In 2004, the average unpaid student debt was approximately $18,650...

One of lesser-known benefits of exploring outer space is the medical breakthroughs scientists discover. It is true that space in a gold mine for much of the modern day health discoveries, yet many people don’t seem to have knowledge of this. A few major medical devices are, a laser angioplasty, an ultrasound skin damage assessment, a human tissue stimulator, and a cool suit. These are only some of the prominent discoveries made a group of intellectuals aboard the Internation Space Station (ISS). This band of people uses the unique aspects of outer space such as zero gravity to perform and uncover new information about medicine (Ferrell).
