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 the possibility of asteroids colonization. The author of the task feels that three reasons make a living on asteroids possible. The lecture challenges the claims made by the author. He believes that asteroids colonization is not a practical idea and each of the reasons mentioned in the article has a downside.
To begin with, the author argues that the gravity on asteroids is lower than on other planets. The article mentions that this would facilitate living on asteroids by landing safer. The lecturer challenges this argument. He claims that low gravity would cause serious health problems. He explains this by mentioning that low gravity would cause a decrease in muscles mass and bone density.
Secondly, the writer suggests that mining valuable metals on asteroids is a driving force for asteroids colonization. The lecturer, however, refutes this by mentioning that supporting colonies and transporting metals from asteroids to the earth would cost plenty of money. He also notes that the availability of valuable metals would decrease the market price.
Finally, the author posits that asteroids are easier to reach compared to other planets. In contrast, the lecturer's position may seem easier to reach asteroids, but it is not easy to return. He notes that asteroids move away from earth's orbits at some point, making the return journey more challenging.
