TPO-52Asteroids 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 lecturer refutes all three arguments presented in the reading passage, which is about the asteroids- a good option for colonization by humans. The reading suggests the asteroids can accommodate humans and entice them with their benefits like Mars or the moon. However, the professor challenges all and claims that this idea is not practical and each of the assumptions had a serious downside.
To begin with, the reading posits that the low gravity of an asteroid provides easy landing and takeoff by a spaceship. The professor, on the other hand, says that humans in low gravity environment present certain health risks. Loss of muscle mass and bone density are the detrimental health problems faced by most of the astronauts. Therefore, long term colonization in asteroids is not imaginable.
Second, the passage points out that asteroids are a treasure house of raw metals like gold and platinum that seems profitable to the colonizers. The professor, in contrast, tells that additional factors like the cost to support the colony and the transport of metals to the Earth may be much high that it overweight the profit. Furthermore, there is no guarantee that the price of the precious metal in the markets will remain the same, as there is a surplus from the asteroids.
Finally, the professor added that the orbital path of asteroids is unpredictable. In fact, asteroids may come closer to the Earth in a particular place but they cannot stay close longer. As a result, the astronauts can't trust the orbital path for their colonization. This is a great disadvantage of the asteroid trip.
