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 lecture and the reading article are discussing about the colonization of human on asteroids. The lecturer in the lecture is not convincened by the points mentioned in the text and explain in detail each and every point. However, the reading text provides three crucial reasons in support.
To begin with, the first issue we encounter is with the effects of lower gravity of asteroids on astrounauts. The professor highlights that it is not a valid reason and has some flaws in it. He said that it is not a practical and have seroius downside. ALso, it comes with some risks like astraunuts loose muscle mass and have decrease bone density due to low gravity. Moreover, long term colonist may have to face health problems. On the hand, the reading covers that because of low gravity landing will be easy, less fuel will be used and more equipments will be taken in spaceship.
Secondly, the another topic for debate is the mining of valuable metals. The speaker points out that this is not the whole picture. When we mine metals in space, it will be more expensive. Furthermore, the target market will not be same as when supply increases demand decreases. While, the reading states that as asteroids are rich in gold and platinum, they will be of graet benefit to bussinesses related to them.
Finally, to wrap the things up the final point of discussion is feasibility to reach the asteroids. The lecturer suggest that it is no doubt correct that asteroids are easy to reach but may be they are not easy to to returun from. To add on, they have unusal patterns. Sometimes some of the orbital paths come close to earth but may travel further away and will be a great challenge to get back to earth. Nevertheless, the writer believes that they periodically come closer and so will be much feasible and and a chaeaper way to get and come back as compare to other planets.
