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.
Scientists are looking for alternative options such as Moon or Mars to establish colonization of human beings. The text refers that inhabitation in Asteroids would be the right choice because of some key features and benefits. However, the speaker is not convinced with these points since they seemed impractical to him.
The first point of dispute revolves around the low gravity and its' impact on the placement. The speaker opposes the idea since it involves some risks. More specifically, he mentions that the astronauts will be subjected to severe muscle and bone diseases because of low gravity. On the top of that, long exposure in the spaceship will degrade their muscle and bone system. Therefore, it will not be a benevolent strategy to execute. On the other hand, the reading cites the benefits of the low gravity of asteroids. It mentions that low gravity will ensure safe landing as well as taking off the spacecraft and also preserve fuel consumptions.
Moreover, the debate extends to the context of obtaining valuable elements in the asteroids. The professor is highly skeptical about the net worth of the whole process for two specific reasons. First of all, the speaker mentions that the costs for the whole process will be high enough to justify the actions. Secondly, the price of the items will be fluctuated when the parent source is discovered. To be more specific, whenever the buyers will learn about the supply source, demand of those expensive goods will be reduced, so the price will be fallen too. On the contrary, the article believes that that asteroids are good sources to make profits by selling the high-priced metals.
Last but not the least, the final argument is connected to the ease of travel to the asteroids. Although the professor acknowledges that reaching the asteroids will be easy, the return will be rigorous for the travelers. It is because most of the asteroids are changing their positions according to the rotation of the orbitals. Therefore, the settlers might reach the asteroids safely, however, the asteroids might move a furthest distance from the earth that they cannot return easily. Conversely, the passage finds it handy in terms of settlement since asteroids are located very closed to earth unlike Mars or Moon which are located far away from our planet.
