Essay topics:

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.

Both the reading passage and the lecturer discuss the posibility of astroids colonization. While the reading passage brings three reasons make astroids livable, the lecturer finds these reasons impractical and brigs some evidence to refute them.

First, the writer asserts that the low gravity of astroids makes situation proper for landing and taking off the spacecraft. On the other hand, the professor says that the low gravity has some harmful effect. For example, the astroments who live in the low gravity on the oribts surround the Earth, suffer from bone density. So the low gravity can threat health of the human.

Second, the author believes that valuable metals which exist in astroids can bring enourmos profits that can support journy's costs. In contrast, the professor says that its not the whole advanture. When the suppliment of the valuable metals increase, then the market price of them will decreas. Beside, there is no gaurantee in finding metals, and it would be risky.

Finally, the reading declares that reaching to astoids is even easier than reach to some orbits surrounded Earth. Still, the lecturer states that while reaching to astroid is straightforward but returning to Earth would be complicated; Because astroids move and getting away from Earth after a while.
