Subject: Do the space ships and sattelites which leave earth, affect the earth....?

When space ships and satellites leave earth, they take a certain amount of 
matter with them i.e., they weigh a certain amount. When that is gone from the 
earth, the earth could be said to be "lighter" even though in a very very minute 
way. Also when they leave earth's atmosphere, and also when they re-enter they 
are creating friction with the earth's ozone aren't they? 
So taking these two factors into account, isn't it possible that the earth's 
spin and movement around the sun and universe could be ever so slightly warped 
over time, creating a new orbit for earth, and maybe even chaging the climate of 
the whole world?
Thanks in advance
