From the earliest times, people have looked up at the stars, the
moon and the planets - now, we know more about them than we ever
have. Today, people can train to be astronauts, work in space, or
join a future mission to Mars. Did you know that the first
astronauts were animals? That for astronauts working in space, the
sun rises 15 times in 24 hours? Do you know how you might train to
become an astronaut? Or where astronauts might explore next?
