Nuclear power stations work in fossil fuel-burning stations‚ except that a "chain reaction" inside a nuclear reactor makes the heat instead.The reactor uses Uranium rods as fuel‚ and the heat is generated by nuclear fission: neutrons smash into the nucleus of the uranium atoms‚ which split roughly in half and release energy in the form of heat.Carbon dioxide gas or water is pumped through the reactor to take the heat away‚ this then heats water to make steam.The steam drives which drivegenerators

Through time‚ humans have dreamed of travelling across the stars to the exoplanets we’ve spotted far away‚ but such a trip would be very long. Even to travel at the current space speed record to the nearest known exoplanet would take 43‚000 years (4). All that aside; the main issue is sustaining a human population for that long‚ if it were based generation to generation it would take roughly 600 generations of humans before they arrived based on today’s current life expectancy (3). This issue isn’t

decades‚ the exploration of the universe has not been stopped. It has always been an unkonwn world which humans are curious about.With the developement of the technology‚ the outer-space is not a strange term to humans any more.

Space exploration is a highly debated topic on whether or not it should be funded by the government. Currently‚ the United States spends $19.3 billion on space exploration out of its $3.95 trillion budget. Many people argue that the money needs to be spent on other issues like health care and help for the impoverished. Space exploration is an important field that the US government needs to focus on and fund because these endeavors can provide a national space defense‚ push us towards the future of

Thompson Ashford University English Composition II ENG 122 Rosalinda Ortiz October 15‚ 2014 Why do people support space exploration Why do people support space exploration. Man has to look to the stars‚ to find new resources that he needs to build new society’s on other Worlds. The expansion of the human race is paramount for man’s survival. Why do people support the exploration of space. First‚ we need to go over a little bit of history of space exploration. After

------------------------------------------------- Space exploration is a waste of money Against space exploration Science may well give us good things. We all know Velcro came from NASA. But why bother spending all this money exploring space and finding out there was water on Mars at some point in the last few thousand years (we have water in Earth) when these same great minds could be applied to finding better ways to power humanity’s insatiable desire for energy‚ to feeding the starving millions

Pros and Cons of Space Exploration We plan vacations to tourist spots nearby; we plan to spend holidays to faraway lands. But how would it feel if we could plan a vacation to Mars? How would it be to plan a holiday to some ’tourist destination’ in space? Won’t it be exciting? Definitely‚ yes! Although it sounds unbelievable‚ it has the potential of becoming a reality. The dream once dreaded is seen with thrill today. It is on its way of turning true if we succeed in exploring space. Astronomers and

complications such as "back contamination"‚ bringing diseases back from space‚ and "forward contamination"‚ bringing Earth’s diseases into space‚ should be taken into account (Source F). However‚ these sorts of problems are not unsolvable. They are simply an issue of ethics. In "To Boldly Go: Ethical Considerations for Space Exploration" (Source E)‚ Margaret McLean takes a similar stance. She isn’t against space exploration altogether‚ but instead advises explorers to "account for [their] urges and

I think space exploration is good thing for this world because we might find pterodactyl next big thing in space. I’m just saying that maybe we find the cure for cancer in a faraway planet or find a way to go into the past like time travel space is too big to look at thru a microscope but if we spend money we could be saving lives by the thousands instead of 7.6 million dying each year. I think president Kennedy was right for having such a liking to the space exploration and for thinking about
