1. I'm over the moon
  2. I feel like nothing I'm doing has any real weight
  3. This place makes me feel like an alien
  4. You seem to be missing the gravity of the situation
  5. There was a palpable change in atmosphere
  6. I feel much better -- I just needed a little space
  7. Uranus looks huge from here
  8. He's a real space cadet
  9. You're doing the moonwalk
