Recommended: The long term physical effects of space flight
The controversial question being debated right now is “Should the U.S Federal government increase space exploration beyond the earth’s mesosphere?” The mesosphere is the middle layer of the earth’s atmosphere. Increasing space exploration would be a terrible idea. Space exploration takes a major toll on astronauts’ physical health, takes away the precious time they would have on earth and on a larger scale it takes away much needed money from problems on earth. Astronauts physical health is highly affected when in space for long periods of time. Based on the data from the video “5 Ways Space Travel Affects the Human Body”, space travel increases risks for a person’s health. In space there is no gravity causing loss of muscle mass and density. The amount of pressure on the head causes permanent eye damage. When in space the heart is under less stress making it lose muscle mass causing it to form a more spherical shape leading to …show more content…
Although it might answer many questions, space exploration comes at a high price. Based on data from the video “5 Ways Space Travel Affects the Human Body”, the NASA budget in 2007 was $16.3 billion. Some valid points were made in the article “The Space Race is a Pointless Waste of Money” by Jerry DeGroot. He stated “...seems like lunacy when terrestrial frontiers such as disease, starvation and drought cry out for cash.” We must solve these problems before we start to explore for fun. DeGroot quotes President Eisenhower, who could not have said it better, “‘every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed’.” Before spending money on space exploration the U.S Federal government must put money into taking care of the U.S
Such as poverty and health-care, but in fact NASA 's funding is only a half a cent on the dollar, and the U.S. spends most of its deficit on war and other barbaric acts. About 2.9 trillion dollars are used on health-care alone (Millman). The U.S. government spends a mere $17.7 billion on NASA and spends more than 36 times that on defense $647 billion, with nearly $20 billion alone in 2011 spent on air conditioning tents. Since NASA’s Cold War glory days, the budget has gone from 4.41% of the total budget in 1966, to less than 0.45% today, its lowest ever. NASA helped to usher in a promising new future in the 1960s and it was rewarded with a rapidly-eroding budget. The U.S. should invest more money in NASA and less on unnecessary health care and military. The budget cuts are affecting our technology development. Evidently, Increasing NASA 's to 1 percent of the federal budget will not hurt the economy. But instead it would benefit it by creating jobs here on earth, especially for the next generation of American scientists and engineers. By increasing funds it would support cutting edge aeronautics and space technology innovations, education, and development that will help fuel the nation 's economy for years to
Space has lots of radiation. Exposure to space radiation can have a bad effect on a person’s health. Support C: Travelling and exploring space can actually endanger the life of an astronaut. THIRD POINT:
Have you ever wondered what Earth was like without space exploration? In the story Leaving Main Street the author states, “The United States has more important things to spend money on.” On the other hand some people believe that successful space programs adds to our economy,national prestige,create jobs,and improves national security. We shouldn't spend valuable resources on space exploration, because we could end hunger and poverty.
Also, if they are going to even consider sending people into space they need to double check and triple check everything on that spacecraft. They should, also, test the spacecraft, spaces suits, hab, etc. before they go and send LIVE people into outer space. It is not fair that families have to worry if their loved ones will even come home after traveling into space. It is not fair that the space crew has to worry if they will even make it back to the ship alive because they are traveling to a place that is not even relevant to anyone or anything that we do on
“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 “...
As a country we need to start investing more money and research into space technology. Programs currently exist for this effort, but the potential for research and progress is limited by a lack of funding; compared to other government funded programs, aerospace funding is pitiful. Continued research in space technology is a necessary step in our growth and development not just as a country but also as entire human race. If we are to achieve this goal, it is necessary to increase funding for space research and technology and consider the possibility of colonizing outer space. If we limit our existence to the planet Earth, and continue to drain the resources on this planet, we will destroy the only home we have.
However, while space exploration- essentially research- is thought to cater to the Americans as a whole, the goal for companies like SpaceX or Blue origin-private space ventures- is meant to cater to the desires and CEO’s or leaders. NASA, funded by American tax dollars, is meant to procure knowledge for the American public. However, ironically, the majority of the country seeks no interest in pursuing space exploration and more specifically doesn't want to see their tax dollars going to a program they seek no interest in. In fact, in an Msnbc, meet the press edition, with Michael Griffin, NASA Administrator and MODERATOR Tim Russert describes that 60% of Americans demonstrated no interest or appeal for space exploration, and more importantly, public space funding(Russert).
The relatively large investment that the space program invokes has not gone without criticism. Some argue that funding the space program is too costly and there are other outlets for the space program’s funding that could give more immediate and tangible benefits. In a Forbes article entitled, “The Cost of Space Exploration”, Dr. Michio Kaku, a renowned theoretical physicist, states, “…to put a pound of anything on the moon costs about 10 times as much. We are 50 years into the space age and yet space travel is just as expensive as it always was”. He claims that certain facets of the space program are still relatively high cost, and asserts that more resources should be diverted to research and development that lower the substantial costs of space
Carl Sagan once said “every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds.” The National Aeronautics and Space Administration or NASA, is executing Sagan’s words every day. President Dwight D. Eisenhower created NASA in 1958 with the purpose of peaceful rather than military space exploration and research to contribute to society. Just 11 years after the creation, NASA put Neil Armstrong and Buzz Aldrin on the moon, the first humans to accomplish this feat. NASA’s research and innovation looked promising but it came at a cost. Money, resources, and spacecraft accidents most famously Apollo 13 all hindered NASA’s research. In the 21st century the debate between funding for NASA is at its peak since the birth of the organization in 1958 especially when there are numerous problems throughout the world. Is the money spent on space exploration worth the advantages and advances it contributes to society?
As such, this essay will argue that space exploration is a necessity of our kind and that NASA should be progressively more financed. To begin with, space research has helped bring several developments to modern science, affecting the quality of our everyday lives. With issues like climate change, and population overgrowth, our species faces the risks of major extinction (4). Climate change has been a man-made problem in recent years that threatens our planet. It will take huge mitigations from current and future societies to even come close to reversing climate change.
In America, space travel is a controversial issue that many discuss. Although exciting, some people find it unnecessary and a waste of money. There are also many risks associated with space travel and many issues are more important than space travel that should be focused on. There are ethical, diplomatic, and economic issues that need to be considered before making decisions about space exploration.
Mankind has always been fascinated with exploring the unknown. From sailing to distant lands to someday setting foot on other planets, the spirit of exploration is the same. Bur now with the current economic situation and the high cost of sending people to space, NASA is being looked at as a way to free up some much needed funds. Although, there is many problems here on planet Earth that need addressing, the benefits of space exploration far out weight the disadvantages. Space exploration has given us more advanced technology, advances in the medical field, and a boost to the economy and these facts cannot be disputed.
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.
Most people think that the costly downside to funding space exploration is a reason to avoid spending money on sciences and instead spend it on problems here on earth, but such funding for space exploration actually promotes economical as well as scientific benefits. Space exploration is an important expenditure for the high cost because of the potential for numerous benefits such as the possibility to find useful resources to cultivate, space exploration and satellites produce many thousands of jobs in our economy, and it creates and discovers newer and better technologies through research and development.
Space exploration is very beneficial to humankind because it creates new technologies, it brings different countries together, and gives people a better understanding of our Earth.
