 1. The concept of a spacecraft factory in the video is very impressive in many ways. The idea is now in the realm of science fiction, but it has the potential to become a reality in the future. Here are some noteworthy points about the spacecraft factory. Spacecraft factories are useful for resource utilization. Using resources mined from asteroids, the moon, Mars, and more, we can manufacture structures and parts. This can save money and energy to transport resources from Earth. For example, materials are extracted from asteroids rich in resources such as metals, water, and carbon and used in their manufacturing. They are also very useful economically. They can reduce the enormous energy and money needed to escape from Earth's gravity. Manufacturing spacecraft directly from space can reduce the cost of launching a spacecraft from Earth and devote more resources to space exploration.

2. This video talks about the feasibility of a spacecraft factory. Building a spacecraft requires a lot of budget and money from a country. Therefore, I think that if a spacecraft factory is built, it can be effective by utilizing the strengths of each country because mechanized systems and countries all come together to build it. In addition, as a new industry is created, new jobs will be created and it will be of great help to revitalize the economy. I also think that spacecraft exploration will be expanded and more information about space will be learned.

3. In class, I talked about "Why do people cooperate?" Likewise, countries cooperate in pursuit of economic profit. I think that if we fill in each other's shortcomings, learn, and cooperate, we can bring good results in new ways.
