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.
In this set of materials, both the reading and the lecture discuss whether or not Asteroids is a good place to establish colonies of human. The reading states that sending people to Asteroid is would be the best idea than sending them to Moon or Mars while the lecture argues this by saying that colonies on Asteroid is not a practical solution and there is a down side for it.
First, the reading claims that Asteroid has a low gravity which make landing much safer than landing on Moon also carry equipment will be easier to set up the colonies and less fuel to back to earth. However the lecture refutes this by states that even low gravity is risky. People lose muscle and bone density and even few month trips in space have this affects so what about colonies? will lead to health problem.
Second, the reading states that Asteroid is rich with precious elements such as gold and platinum so the colony businesses will pay for the cost to sending them back to earth. The lecture conflicts this by mention that this is not the whole picture, the cost to support and transport the metal is less profit and there is no guaranty to sale these metal as the same .Furthermore, as the supply of these metal will increase the price will go lower.
Third, the reading argues that Asteroid is a good colonization because some of them are easy to reach as they actually get closer to earth than Moon so will be easier to get to and get back to earth. The lecture argues that . It states that Asteroid is not easy to reach and return as its orbit is an unusual become closer to earth in one point and faraway a distance than mars itself in other point which will be challenging trip.
