Investing in space exploration missions may just be the key to ensuring the future survival of the human race. From mining resources to solving the problem of overpopulation, there are many benefits to space exploration. However, there are also challenges when it comes to just simply putting people up in space. While the environment outside of Earth’s atmosphere is fraught the danger, the lack of gravity itself can have an adverse effect on the human body. We are constantly putting our bone and muscles to work even if we aren’t actively taking the time to exercise. The gravity on Earth plays a key role in the development of our bones and muscles so as such, a weightless environment can be detrimental to our bodies. The lack of gravity means we that we don’t need to use certain parts of our bodies to move around or even to keep ourselves upright. A long term lack of muscle utilization can cause those muscles to decline and eventually weaken. Reduced muscle fitness of crew members can prove dangerous particularly when there are certain situations that may require physical exertion to …show more content…
In much the same fashion as a soldier spending long periods of time on the battlefield and having to face the challenge of returning to a life of normalcy once their combat tour is over, an astronaut may face challenges of having to mentally re-adjust to a normal life after coming home from a long-term space mission. Seeing the Earth from the cosmos and feeling disconnected may still linger even if that person longed for such a return. To them, everyday life might seem so minuscule and irrelevant in the grand scheme of things since that’s how it might have looked from space. Even if they are literally back on Earth, their mind might have been affected so much so from seeing our planet in space that the life they had and the person they were might have been lost in space
The word race is defined at its core as a competition between runners, horses, vehicles, boats, etc. to see which is the fastest in covering a set course. Well, interestingly enough, a race of a different kind occurred between two countries from the years 1957 to 1969. The competition was unclear, and the opponents were on two entirely different continents, not something as simplistic as two horses. The United States and the United Soviet States of Russia both set out as arch rivals in the “Space Race,” a quest for dominance beyond the known Planet Earth. Ironically enough, just as communism was spreading to all parts of the world, the United States always sought to squash this form of government, despite somewhat dire consequences. Now, with
“Space, the final frontier….” These are the words that stirred the imaginations of millions of men, women and children with the debut of “Star Trek” in 1966. The show has arguably one of the most loyal followings of any production, and has inspired scores of people to consider the stars and wonder if we as a people will ever travel outside of our own solar system. The idea of space travel and exploration was not new when “Star Trek” hit the airwaves though. The United States was at odds with the Soviet Union, and both powers were locked in a battle that would come to be known as “The Space Race” during the height of the cold war. It was in 1961 that President John Kennedy made his famous appeal to the American people, challenging us as a nation to put a man on the moon before the decade was out. On July 20, 1969, that challenge was achieved when the astronauts of Apollo 11 made the first manned landing on the moon, and returned safely to earth. This, the highest achievement in the United States space program, will turn 45 years old this year. After 45 years, and a technological explosion over the past 25 years, the greatest achievement in the space program has been a manned lunar landing. Countless billions of American tax payer dollars have been spent on the space program over the decades, and there have been no achievements to match that of the moon landings. Though the budget for NASA (National Aeronautics and Space Administration) is but a tiny fraction of the entire annual budget for the country, many of those billions that are allotted in the NASA budget for space exploration would better serve the country if they were re-directed to other areas. De-funding the space exploration portion of the NASA programs could create a “...
Support A: SECOND POINT: Astronaut’s health are the first priority before travelling to space however, it is proven that space exploration or staying in the space can actually affect a person’s health. Support A: According to a study done by NASA, astronauts that stays in space for six months or even longer are found to have some changes in their eyes and their vision.
To begin with, we will discuss the effects of gravity on the body in the regular or "on garde" stance., and what forces are used during the "thrust" and the "lunge".
NASA has made great advancements, we continue to explore the vast solar system filled with magnificent sights. There is so much more out there, from black holes to some of the biggest stars coming to the end of their life cycle. With all this out there waiting for us why don't we pursue all the possibilities out there, all the knowledge and advancements we’d gain would be significant. We must continue to fund these space exploration projects to see all that there is to see. We would discover there’s more to space than we think maybe more the the life cycle of a star or more to nuclear fusion. It's important that we expand and explore to find a new planet, one day this planet will die and we need somewhere to go and something to do, if our species wish to live on. Its also paying off in many other ways. Technological advancements you see today like your phone was possible through space exploration even though you may not think of it. The space programs have made huge advancements in our world such as more fire resistant clothing and, car interior. We went from having a 70 pound micro computer with just 40 KB of memory (Less than a GB, Less than a MB(Which is 100 times smaller than a GB) so it's 40/1000 of a MB) Today we have 1 TB(1000 GB) flash drive the size of your thumb in just about 40 years. Allowing us to miniaturize
These organs are used to support the body in the constant pressure of Earth’s gravity, but due to the microgravity conditions in space make these structural organs almost useless. The weightless environment also causes poor posture on the part of astronauts, and standing straight takes considerable effort (Mann, 2012). NASA has found out, in an evidence report published in 2015, that this is an atrophic response on the part of the muscles, to adapt to the reduced gravity. Skeletal muscle attrition was also common in the expeditions they studied, and several MRI results even confirmed that the atrophy continues during longer exposures to
The book Packing for Mars by Mary Roach is mainly about the science behind how much a human body can take in space. In the summary, written by Roach it quotes, ”Space exploration is in some ways an exploration of what it means to be a human. How much can a person give up? How much weirdness can they take? What happens to you when you can’t walk for a year?” Roach explains the science behind how zero gravity effects humans, or even monkeys, bodies in space. She explores multiple countries and methods during her quest to find out what space really can do to the human body.
Knowing the impermanence of the Earth, do humans have a moral obligation to find and
Space, a vast and cold vacuum that much is yet to be explored. It all started in 1957, when the Soviet Union launched the first satellite, Sputnik into space. This launch caught the attention of people all around the world. As a result, it sparked the space race between the U.S and U.S.S.R. Since then, there have been many missions to space, but all these missions come with a cost. In 1981, NASA launched the first reusable space shuttle which was subsequently used for thirty years, however this cost about $209 billion over the years to keep maintaining it. The launch of a single space shuttle costs approximately $450 million and over the years there have been 135 launches. So why should governments and taxpayers spend billions of dollars on organizations like NASA, when so many problems already exists here on Earth? Although space exploration and research may cost a lot of money, I believe it is worth the cost as it has benefited humankind.
Problems included the effects of zero gravity, how to make a sustainable food source in space with a limited supply of water, how to stay fit, & how to keep food from spoiling in space for the long-term trip from Earth to Mars and back.
Space Exploration promises to improve the quality of life on Earth. The enhancements include improved economic prosperity, health, environmental quality, safety, and security. Space exploration leads to advances in science and technology which then yields many benefits. Scientific knowledge acquired from space expands humankind's understanding of nature.
Many people alive today will fully say that space exploration is something best kicked to the curb. Jeffrey Kluger’s article “The perfectly Sane Case for Life in Space” shows some very extreme and pretty subtle ideas about space. Kluger goes into his article about living in space and shows that many astronauts have actually done it for over a year or a little under a year but he does say that after prolonged living in space the people that come back are usually fatigued or heavily plagued with sickness or sore muscles and bones. This is one of the major factors making people not want to take prolonged trips in space as well as it is holding back the use of space hotels and military installations in space. While in space these individuals are perfectly fine and in good health making most people that are for life in space think that if you go up there, then you stay up there as its a permanent choice otherwise you are possibly plagued with sickness and despair for the rest of your life if you come back down to earth.
THE MOST PROFITABLE BLANK , SPACE “The spacecraft carries along our secret hope that there is something better out there, a better place, a better way to live, a world where we may someday go and leave the errors of the past behind”( Easterbrook, 1986, para. 1) emphasized the importance of the space research well. Because space is the limitless blank and it is full of chance, chance of new lives, new resources, chance of a new page for humanity and meeting new species. Then, what is space research and how is it done? Logsdon(n.d.
Humans can expect to face some major challenges on an expedition to Mars. It has been proven that humanity can travel in space for over two years. Cumulatively, Sergei Constantinovich Krikalev, a Russian cosmonaut, has spent over eight-hundred and three days in Earth orbit (Lyndon B. Johnson Space Center, 2005). The expedition to Mars would require the crew to endure a six month journey to the planet, a year of living on the planet, and a six months journey back to Earth. Russian cosmonaut, Valery V. Polyakoz, clocking in at four-hundred and thirty-eight days for just one stay in Earth orbit, shows humanity is capable of a twelve month round trip to Mars (Schwirtz, 2009). Earth's orbit has provided some benefits to space exploration, like the magnetic field from cosmic radiation, and the proximity to Earth if an emergency were to arise (Jones, 2009). The further humans travel away from Earth the greater the risks become. The major risks to human health on a flight to Mars, living on Mars, and returning to Earth are: radiation exposure, biological problems induced by weightlessness, spacecraft malfunctions, and psychological problems brought on by isolation.
Imagine if space tourism existed today. If they had the technology and other necessities they need to take people to space. Many people today have dreamed about going to space, and traveling throughout space. Many different things attract people to want to travel space. Aside from those who have already been to space, some say it’s an enjoyable life occurrence. It may be very engrossing experience to have a view of earth, stars, and other planets. It could be a very overwhelming event. They’d have to build very powerful reusable spacecrafts to make space tourism happen.
