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.

The reading passage and the lecture are both about Astroid colonization, based on which people can stablish some colony on near astriods. While the author of reading believes that is would be very profitable to colonize on an astroid, the lecturer casts doubt on the statements made by the author. He is of the opinion that astroid colonization is not practical.

Firstly, the author suggests that because of the low gravity on astroid it is more easy for spaceships to land in the astroid or take off from it. the passage also clarifies that by this, spaceship can bring more equipments needed. Conversly, the lecturer challenges this argument by saying that low gravity also bring a lot of risks and health problem, namely musle mass lost and bone density lost. Moreover, he points out that because of this leath problems the mans on the international space station can not stay there more than a certain time and this would be worsen for long term in a astroid colonization.

Secondly, the reading specifies that it can be profitable by mining some valuable metals which is plentiful in the astroids and send it back to the eath. The lecturer, on the other hand, rejects this idea by describing that you must consider some other factors such as cost. the cost of transporting the materials to the earth woud decrease the profit of mining. Besides, he mentions that if we bring huge amout of this metals to the earth it will lose its value and the price will not remain the same.

Thirdly, it is stated in the article that some astroids can easily reached due to the low distance to the earth. The professor, however, argues that the way that astroids rounds in the space will make is some times near to the earth and then it will go far from the earth. He explains that although we can easily come to the astroid, it does not stay at the same point and it will be very hard to come back from it.
