Why would humans consider establishing colonies on Mars?
Katie Answer: Hi Katie, Colonies on Mars would allow us to do more sophisticated studies of that planet which would help us to better understand our solar system, the Earth and possibilities of life. There are other results as well, such as advancement of technologies (which can lead to “spin-off” products like cell phones and CD players)and such as exciting our spirit of exploration, of learning new things and of finding new questions to ask. Thanks for your question.
