And if any of you were alert and coherent during the 1960s -- and we'd forgive you, if you weren't, OK -- you would remember this very famous picture taken by the Apollo 8 astronauts in 1968.
Se estiveram atentos e coerentes  durante os anos 60 — nós perdoamos-vos  se não estiveram — lembrar-se-ão desta foto famosa tirada pelos astronautas  da Apollo VIII em 1968.
