say that space exploration should be abolished because it is a waste of money‚ but think of how much we have advanced in our knowledge of space. This has to be known because some of the planets and moons we have discovered are suitable for us to live on when we move from Earth‚ so it is essential that man knows about space and we constantly have to keep updating and developing our knowledge. "I don’t think the human race will survive the next thousand years‚ unless we spread into space. There are
