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 article and the lecture are both about the asteroids as the best feasible option for the colonization. The author presents three theories about the feasibility. The lecturer disputes that the claims made in the article. His position is that they are all incorrect.
According to the reading there is a low gravity in the asteroids. As a result the pull experience by the space crafts is low, which will make the landing more safer and smoother. The article mentions that low pull allows space craft to store more fuel which will be beneficial during long distance travel. This argument is challenged by the lecturer. He claims that low gravity leads astronauts to loosing muscle mass and decrease in the bone density. Additionally he pointed out that such health problem may be deleterious to the long term colonist.
Secondly author suggests asteroids consists of huge sum of minerals which are yet to be mined. In the article it is said that such minerals are valuable source of raw materials. Therefore is it profitable. However, lecturer assets that the article didn’t took the cost factor into account. Due to the large sum of cost associated with the transport of such materials and supply of colony for the mining, the profit margin drastically decreases.
Finally, the author posits that since the asteroids comes near the earth periodically, it is easy to travel and set colonies in asteroids as compared to the mars. He contends that due to the distance factor it requires only one trip to reach asteroids. In contrast, the lecturer stance is that, it is easy to reach the asteroids however returning from the asteroid is whole different story. He notes that the asteroids does not stay close to the earth for too long on top of that the orbits pads moves far off from the earth.
