With people now living on the Moon, Mars and associated spacestations, it is clear the spaceship industry has become an extremely important part of human society. In short, had spaceships not been developed to allow humans to travel in outer space to and from various celestial objects, then living on them would not be possible. The major breakthrough was to develop spaceships that were not only reliable and safe, but also relatively affordable. Today, a pre-owned spaceship that could feasibly take a person from Earth to Mars in comfort can be obtained for as little as Cr 15,000, or about the same as a reasonable yearly wage.
