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 and lecture are both about as asteroid colonization. While article suggest some of the benefits of establishing colony in asteroid, the lecturer says these points are not practical and thus asteroid is not a good place to colonize.
First of all, the author points out the benefit of low gravity which helps spaceship for safer landing and the better possibility of carrying more things to set up a colony .This point is challenged by the lecturer. She suggest than the low gravity condition can leads to many health condition such as muscle loss and less bone density. She also points out that when scientist spend few months in asteroids they often suffer from these issues, so colonization which means many more days will not be possible.
Secondly, the author posits that since the asteroid has precious metal, mining this metals and sending it back to earth is a good way to manage the expenses of colonization . The lecturer, on the other hand, feels that mining valuable metals have some additional cost of transportation. She also puts forth the idea that there is no guarantee that the price of these valuable metal sustain when there is huge supply in the market.
Thirdly, the author declares that asteroids are a good option for colonization because some of them would be very easy to reach. The lecturer rebuts this argument. He mentions that even though it is easy to get into the asteroid as most of them come close to our planet, it often move very far distance from the earth, which makes it quite difficult to return back to earth.
