Summarize the points made in the lecture, being sure to explain how they respond to the specific points made in the reading passage.
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.

According to the reading, they author believe that sending people to an asteroid would have 3 benefits, however, the lecture cast a serious doubt on what was written in the reading.
Firstly the reading thinks that asteroids have less gravity because they are much smaller than planets. The aircraft's wouldn't be pulled as strong and it would be easier for them to take off and land. On the other hand, the lecture consists that people in low gravity environments would lose control of their muscles and lead to low bone density. Astronauts who are only in the outer space for several months suffer from all kinds of illnesses. You can't expect a normal person to do any better if they stay there for a long time.
Secondly, the article insists that some asteroids are rich in valuable elements and precious metals, so it would become a good source of these materials. however, the lecture believes there are 2 points wrong. First, the cost to support and transport those elements and metals would rise rapidly, in consider of the long distance. Second, you cannot guarantee that the price of these materials would remain the same all the time. The more amount you mine and collect, the lower the price will be. So it would not be such a good source for mining.
Finally, the reading material maintains that asteroids are often easier to reach than the moon or Mars. Many asteroids periodically come near earth’s orbit, so it would be efficient and affordable to get to and get back. However, the speaker of the lecture believes that it would indeed be easy to reach, but it would not necessarily be easy to return back to earth. The asteroids’ orbits would sometimes come near to the earth, but it would then quickly move away from earth. It would be easy for the spacecraft to get to the asteroid if you calculate the time correctly, but the asteroid doesn't just stay there close to the earth. So getting back from the asteroid would become a challenge.
