the spaceship was used to explore outer space
I think that a 'Spaceship' needs to be defined before anyone answers your question. A Spaceship is a fanciful science fiction object . A Spaceship is not another name for a Satellite or Space Station. Spaceships are the things of novelists whom write make believe stories about people traveling off into outer space beyond the earth's atmosphere. Because there never was and have not yet been any spaceships available for people to travel into outer space, then they are certainly not an invention. They are simply a fictional idea.
it takes 3 years to travel to mars and 3 days to travel to the moon.
In 1987, a group of people launched into the air in a spaceship, but the spaceship exploded in the air leaving millions of people in shock.
