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 t

The reading holds the point of view that asteroids are identical colonization and gives out three reasons. However, the listening holds the contrary view that asteroids also have downsides and argues against three reasons one by one.

Firstly, the reading points out that asteroids have low gravity, which can bring a safer landing. We can carry more equipment and less fuel to return. But the listening refutes against it by saying that low gravity may result in health risks such as losing muscle and bone density. The listening gives out an example saying that astronauts who stay on a spaceship for a few months may suffer from losing muscle and bone density, so living on an asteroid for a long time will surely bring great health risk. Because of this, Asteroids are not identical colonization.

Secondly, the reading thinks that some asteroids are rich in rare materials on earth, which will make it profitable to mine minerals and send them back to sell. However, the listening says that transportation and keeping the mining equipment working properly might be a great cost. What's more, selling the minerals in large quantities may lower the market price. In a nutshell, mining on asteroids is not profitable.

Thirdly, the reading says that some asteroids are easy to reach, which makes them much easier and more affordable to get to and get back. But the listening argues against it by saying that asteroids have an unusual orbit. They may move away from earth for a great distance rather than stay close to earth. In that point of view, asteroids are not identical colonization.
