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.
According to reading passage it is safe to create colonization in the asteroid rather than moon. The author illustrates three reasons to support his opinion. Based on the passage, people will be more benefited since landing on asteroid is more safe than moon, the colonization will be more profitable due to some valuable resource and finally it is easy to reach in asteroid. But, the lecturer clearly opposes this idea and provides specific reasons to describe the problems associated to landing on asteroid.
First, the writer claims that, due to lower gravity on asteroid it is safe to land on asteroid than moon. However, the professor disagrees with that by saying this, although landing is safe but there is risk factor like health problems. Since lower gravity reduces bone and muscle density.
Second, the reading states that, asteroid are rich in precious metal that make the colonization more profitable. On the contrary, the speaker suggests that it does not seem such profitable because, the transportation cost reduces the profit. Again, he put forward his idea by adding that plenty of transportation of valuable metals in the market reduces the price and this case it will not so profitable.
Third, the passage mentions that reaching to the asteroid is easy than moon. On the other hand, the lecture cast doubt on this idea, he says that in spite of easy reaching, it is more difficult to return from the asteroid. Additionally he claims that, asteroid become close to the earth at a certain point and being in a continuous movement it is not so easy to reach to the asteroid
