Error of preposition 

I have changed the following: travel from the Earth to its Moon in July, 1969.

To the following: travel from the Earth to the Moon in July, 1969.

The Moon is not "Earth's Moon", it is the "Moon". It is Earth's "natural satellite", that happens to be named "Moon". Using the term "Moon" as a catch-all for natural satellites promotes ignorance and scientific inaccuracy. No one would call other planets "Earths", so why should other natural satellites be referred to "Moons"?
