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 lecture are both about the possibility of colonization of asteroids as the large space objects. The author of the reading passage states due to low gravity in asteroids, mining valuable metals, and some conveniences to reach to the asteroids, colonization can be applied effectively; however, the lecturer repudiates the idea. The lecturer casts doubts on the three main points of the reading by providing three indefeasible reasons.
To begin with, even though the author mentions that asteroids’ low gravity is advantageous because of a safe landing, carrying more equipment, and easier taking off, the lecture rejects the opinion. He discusses that low gravity causes several severe problems for astronauts. For example, long-winded time can reduce not only bones and muscles density but also their masses. Thus, the reading’s idea is problematic.
Secondly, the author claims that asteroids can be implied as a valuable resource for metals, especially precious and rare ones. On the other hand, the lecturer says that expenditures of supporting and returning spaceships are enormous. As well as, this process will result in disturbing the market prices. Indeed, it will be perpetuated to a state in which many metals prices take a nosedive. Furthermore, there is a weak possibility that asteroids have the rare, priceless metals. Therefore, it seems that this idea is not feasible.
Last but not least, the reading passage shows that asteroids are an appropriate option for colonization because some of them have a predictable and periodically orbiting period. Hence, these asteroids would be much convenient and more affordable to send and return spaceships. However, the lecturer illustrates that this opinion is not feasible because some asteroids are coming near the earth and come back to the vast space. In fact, they go beyond some planets such as Mars, so there is not any guarantee to return.
In conclusion, the reading and the lecture are both about scrutinizing the possibility of colonization in asteroids. Whereas the author buttresses his/her position, the three main points of reading are challenged by the lecturer effectively.
