The Sun's Corona is the Limit

I really wonder how astronauts attempt to instill an attitude of aspiration in their children. They can't say "The Sky's the Limit" because they've actually gone beyond what the sky is generally defined as, which is the atmosphere and outer space of Earth. They probably wouldn't say "Shoot for the Moon and You'll Land Among the Stars" or some garbage like that since they have first hand knowledge that if you shoot for the Moon and miss you're likely headed for the asteroid belt or the vacuum of space.

You know what I think astronauts tell their children? "Pluto's no longer a planet because it's small and no one cares about small stuff."

Astronauts can be snippy.
