All of the energy used to make these things and then launch them into Low Earth Orbit is probably contributing to Global Warming.
However even if it is it the amount would be minute compared to all of the commercial aircraft in use today and the returns in knowledge would greatly offset any contribution. If anything it will most likely help to monitor the Global Warming which was responsible for Mitt not being elected recently.
Kind of Poetic Justice if you ask me a person claiming that Global Warming doesn't exist looses because Global Warming dissuades people from voting for him.
