Asteroids are large space objects made of rock and ice. There are hundreds of thousands of asteroids in our solar system. Though we often hear ideas about establishing colonies of humans to live and work on our Moon or our neighboring planet, Mars, some think that sending people to an asteroid would actually be the best colonization option for a number of reasons.
Low Gravity
To begin with, asteroids are often much smaller than planets, so they have lower gravity. When landing a spaceship, the craft would not be pulled as strongly or as forcefully toward the asteroid's surface, making the landing safer than landing on the Moon or Mars; it would also allow a spacecraft to carry much more equipment needed to set up the colony. It would also be easier for the spacecraft to take off again, so the spaceship would need to carry considerably less fuel for the trip back to Earth.
Mining Valuable Metals
Next some asteroids are rich in valuable elements and precious metals that are relatively rare on Earth, such as gold and platinum. An asteroid colony would be extremely profitable and a good source of these raw materials. The colonists or businesses sponsoring them could more than pay for the cost of their support by mining minerals and sending them back to Earth.
Easy to Reach
Finally, asteroids are a good option for colonization because some of them would be very easy to reach. There are a number of asteroids that periodically come within or near Earth's orbit Some of them actually get closer to Earth than our Moon. So these asteroids would be much easier and more affordable to get to and get back from than a planet like Mars, which would require a two-year trip in each direction.
The reading and the lecture are both about advantages and disadvantages of asteroids.The author of the reading feels that asteroids are large space objects made of rock and ice, so in our solar system located hundred or more.The lecturer challenges the claims made by the author.he is of the opinion that to ssend people to an asteroid is not very practical idea.
To begin with, the author argues that in the asteroid low gravity. The article mentions that it would be easier for the spacecraft to take off again, because the spaceship would need less fuel to come back to earth. this specific argument is challenged by the lecturer. he claims that low gravity can give certain risks.Additionally, he says that people may lose weight and boom density can involve,so humans suffer from health problems.
Secondly, the writer suggests that mining valuable metals, especially gold and platinum, is good idea and profitable business. .In the article, it is said that asteroid has a good source of raw materials. However, the lecturer rebuts this by mentioning that punch valuable metals may seem profitable, but it is not a whole picture. he elaborates on this bringing up the point that there will be also cost,which contains transport and minutiae,there is no guarantee that all these costs would not be profitable for sponsors.
Finally, the author posits that colonies can easily reach. Moreover, in the article it is stated that some asteroids periodically come within earth's orbit and was one trip which got actually closer than Moon. In contrast, the lecturer's position is there is easy to reach but difficult to return. he notes there is great distance to the asteroid.
