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.
Based on the given materials, the article as well as the reading discusses colonization on asteroids. The author states that asteroids have several options which makes them agood place to do so. The lecturer provides several ideas to repudiate this claim.
Initially, it is alleged in the reading landing on and taking off from an asteroid is easier due to their low weight and gravity so it will be safer for people and inreases the possibility of carrying more supply. However, the lecturer asserts that the lower gravity can cause serious health issues for people in the colony. He alludes to astronauts who suffer from muscle mass loses and bone density reduction. Staying long in low gravity environment can cause svere damage to people. Consequently Low gravity has its own doen sides.
Second, the author proclaims that asteroids contain some rare materials and mining them can yield good profit. Yet again, the lecturer underscores that not only the cost to support the colony on an asteroid is high but also transporting the mined materials is expensive. Also there is no certainity in the price of this material as if their production expand their price will decline. Mined material is not a good source to support the colony.
The last point of contention between the reading and the listening passages is the asteroids accessability. The writer states that reaching an asteroid is easy since some times they orbit close to earth. On the other hand, The speaker mentions that albeit reaching them is easier but returning from them can be highly challenging since their route is not a circle. When an asteroid passes close to the earth, it moves away even further than moon or mars which makes it relatively far away to earth. So commuting to an asteroid is not possible.
