steroids 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.
Summarize the points made in the lecture, being sure to explain how they challenge the specific points made in the reading passage.
The professor in the lecture does not agree about the three reasons that provided by the reading that sending people to asteroid would actually be the best colonization option. Therefore, he tries to persuade his class that these reasons are not either convincing or practical.
To begin with, according to gravity, The professor avers that low gravity has many risques. He says that low gravity can cause loosing muscle mas and bone density. Therefore, people can suffer from health problem on the long run. This point refutes the point from the reading which states that low gravity will be helpful.
In addition, Regarding valuable metals, The speaker asserts that it is not the whole picture as, the cost to support and transport these metals will be high. Therefore, no guaranty that the price will be the same. Again This point contradict the point from the reading which claims that mining valuable metals next some asteroids are rich in value.
Last but not least, according to easy to reach reason, The lecture argues that orbits can move away from earth. Moreover, orbits can be close to Earth then move away from earth like Mars. So, getting back from orbit that far away from earth could be challenging. This point casts doubt the point from the reading because the reading says that there are a number of asteroids that periodically come within or near Earth's orbit.
