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
From the reading passage, it proposes that asteroids are a planet that better than Mars or Moon to set up a colony for human to live or work. How ever the lecturer proposes counterpoint to revert the outcome that the reading passage provided.
To begin with, the reading mentioned about the low gravity that unique to asteroid due to the size of the it, thus the spacecraft would be easy to take on and take off and the cost of fuel would be less for the trip back to earth. however, the lecturer make the point of many risks that could happened such as health issues. Losing bone density and muscle mass as a long-term condition would not benefit human. living in the low gravity environment could cause the significant health issues that we could not miss it.
Moving on, the reading passage propose that human can set up a mining company and get profit from the gold and platinum. however, the lecturer brings about the cost of supporting the mining group could be a huge problem. Also the transporting method to taking the precious minerals back to earth, thus the profit would be less than thought.
Finally, the reading passage proposed that the asteroid are closer to earth, so it would be easy to get back to earth. The lecturer mentioned about that the orbit path is unpredictable, probably the distance between asteroid and earth are much far away.
