Why Explore Space (Extract)
文献摘要：
1
Spaceflight without any doubt is playing exactly this role. The voyage to Mars will certainly not be a direct source of food for the hungry. However, it will lead to so many new technologies and capabilities1 that the spin-offs2 from this project alone will be worth many times the cost of its implementation.
