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 article states that asteroids would actually be the best for the colonization option for the human beings and provides the three reasons in order to bolster the claim. However, the professor explains that, colonization of the human beings in the asteroids is not very practical idea and refutes each of the authors reasons.
To begin with, the article claims that, the asteroids have low gravity because they are small in size as compared to other planet, so, during the landing of a spaceship, the craft would not pulled towards asteroids centre strongly and make the landing more safer as compare to other. The professor refutes this point by saying that the low gravity in the asteroids results the health problem in human mainly causing the losing of muscle mass and decreasing the bones density. So, there is a high risks of the health problem in the asteroids.
Secondly, the article states that, some of the asteroids are rich in the various elements and metals that are more valuable, precious and are relatively rare on Earth. So, asteroids colony would be the good source of these raw materials resulting in more profit.In contrary, the professor states that the mining of these valuable metals and elements would result in the higher cost, and, the excess supply of these kind of the material would result in lower price. So, there is no gaurrantee of the profit from the mining of these elements and metals.
Thirdly, the passage claims that asteroids are good option for colonization as they are easy to reach as compared to other planets because they periodically come near or within the earth orbit. But, the professor refute this claims by stating that it will difficult to return in the earth as once reach to the asteroids because the asteroids orbits seems to be close to earth but it moves away from the earth that cause the difficulty.
