Essay topics:

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.

Both the lecture and the article are talking about considering an asteroid as a colonization option. While the author argues that an asteroid is the best option for colonization for three reasons, the lecturer disputes the claim presented in the article. His position is that these three reasons all have downsides.

According to the article, asteroids have lower gravity due to their smaller size. The author asserts that the lower gravity can make the landing safer, carry more equipment, and take off easier. The lecturer challenges the argument. He argues that lower gravity means more risk. It could let people lose muscle mass and do harm to the bone, which can cause health problems.

Secondly, the author contends that asteroids have many valuable elements and precious metals, which is profitable. The article mentions that mining valuable metals can pay for the cost. The lecturer, however, put forth the idea that the transportation cost can be much high, which will reduce the profit. He goes on to say that there is no guarantee that the metals mined in asteroids have the same price as do on the Earth, which means the profit can be small.

Finally, the author suggests that asteroids are very easy to reach, because many asteroids periodically come within or near Earth. He mentions that these asteroids can get closer than Moon. In contrast, the lecturer says that it may be not easy to return from asteroids to the Earth, due to the fact that asteroids can move away from the Earth, and people have to travel a great distance home. Asteroids will not stay in the same position and move away.
