Science Essay
Do you think that Space Travel is worth the cost? Space travel can be very useful. Even though we have several vital issues on Earth, I think space travel is a very meaningful matter as well. Space travel can be important for several different reasons. Space travel is very vital because we can find other habitable planets, find cures for diseases such as AIDS, and further improve our technology. In this essay I will be talking about the benefits of space travel, some costs of space travel, and some approaches we could take toward space travel.
First, space exploration has many benefits. Space exploration helps us with many things. It helps us find new life. Life can benefit us through new cures to diseases and discovery of new technology. If we find new bacteria, it may help us to recover from diseases that we have on Earth such as AIDS, Malaria, and Diabetes. We could also use new cures to completely “exterminate” diseases. Space exploration also might become useful if we find a civilization with advanced technology. We can then use this technology for our purposes. Space exploration can also be useful to find new planets. If our planet ever runs out of resources or dies out, we can use another habitable planet to escape too. One other benefit of space exploration that we can use in the present is that when we go out in space we can use special equipment to locate incoming meteors and other hazards. Space travel research also supplies us with telecommunications, such as radio waves, internet and cable. Satellites that we launch into space stay up there and supply us with telecommunications. We can also predict weather from space. When we are up above the earth we can get a “bigger picture” of earth’s weather. One last benefit is that we can get new medical supplies and drugs. From the new technology we experiment and test with to improve space travel, we also discover that some of the materials and technology can also be well used in the medical world.
Even though space travel has many advantages, it also has some disadvantages. Space travel can be very expensive. It costs millions of dollars just to build one space craft. It also costs a lot of money to build the launch station and buy the fuel necessary for the rocket. One other disadvantage is that space travel is time consuming. It takes years to build one spacecraft and it takes weeks just to reach Mars. One last disadvantage is that it harms the environment. When a rocket launches off it releases a lot of smoke on the ground and into the air. Animals inhale and get sick from the smoke. It can also be catastrophic when an accident occurs, to humans and animals. Even though Space travel has several disadvantages, the advantages outweigh the disadvantages.
Last, I will talk about some approaches to research that demonstrate how important space travel is. There are three different approaches we could have to space exploration. We could use our technology to send more humans to the moon or other planets. I think this approach is most important. If we find another planet, we could possibly also find new life. Also if we invest our majority of resources into finding new planets, we could use those planets as a “second earth”. A second approach we could take is only using earth-based research. This is less useful because we know already so much about our own planet. Although if we do follow this approach, we probably could survive longer on our own planet. A third approach is that we could concentrate on learning more about our solar system. This means that we might be able to do experiments on these planets and also it will not take as long to fly there. One disadvantage is that it is less likely we will find other life. If I were a congressman I would list these subjects from most to least important. In my opinion the most important of them all is Public Health. Then comes Education. Third, Military. After that comes Medical research and Public Utilities. Sixth would be Public transportation. Seventh Space exploration. And finally Social Studies. I think Space Exploration is important but not the most important. Things like Public Health and Utilities are more important. Space exploration is still very important though.
Space travel has many advantages and some disadvantages. Overall that the advantages outweigh the disadvantages. Space travel is important because we can find new resources, habitable planets, life, and technology. Space travel will further decrease our risk of extinction. We also can find new cures as well. Sadly, many countries such as U.S.A. and Russia have been starting to put less and less money into space travel. Other countries such as China are now becoming world leaders in space travel. It is very clear, space travel is vital for our future.
