=== “When I was a little kid, we only knew about our nine planets. Since then, we’ve downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.” — Buzz Aldrin
The moon is squishy.
Like a Koosh ball toy, or a pan of congealed Jello, or a muffin.
