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 about the colonization of people in the asteroids. The author of the reading passage feels that there were several benefits of people sending to the asteroids, and provides the three reasons to support. However, the lecturer explains this is an impractical phenomenon and refutes each of the authors' reasons.
To begin with, the reading says that due to the low gravity, it would be easy to reach the asteroid by the less pulling force. As a result, there would be easy to set up or colonize in asteroids, and finally to back to the earth. The speaker challenged on it by saying that although it would be easy for to and fro from the asteroid to the earth, there would be a high risk on it. Moreover, he claimsFins evidence of losing muscles and bone density loss due to this kind of activity.
Secondly, the article posits that due to the high amount of valuable metals in the asteroids like Gold and Aluminium, which were rare on earth, the colonization would be highly innocuous to the people. The professor challenged on it by suggesting that the real case was different in the case of cost. Sometimes, there would be flexibility in the cost. Additionally, the cost of mining would be too high in asteroids, and moreover, when there would be high mining, there would more production, which finally reduces the cost of the materials.
Finally, the reading argues that it would be easy to reach on the asteroids. It elaborates on this point by saying that many asteroids were close to earth's orbit. On the contrary, the professor opposes by saying that these asteroids were closer and farther at different instants. According to the professor, when the asteroids were closer, it would be easier to colonize for different people, but when it would be farther, it leads difficult to return back to the earth
