The moon or mars??? i have an essay and dont know what to pick furst i thought of the moon and than switched..?

Well, thank you little miss mary, I am going to really read that later on tonight. The subject that I think that you could stick with is Mars and the reason why is because you could mention the NASA has now ended the shuttle program and replaced it with the constellation program. Mention little facts about the moon that might have things to do with Mars and maybe add some extra knowledge to the paper. I hope that this comes to help you on your paper and many more to come.
