^the sun wont be going away for a VEERY long time, and nasa is already talking about putting bases on the moon around NOW like in the present-2015 range, they'll eventually get to mars, it wont take a billion years to get there technology improved so much in only 40 years imagine another 100 or 200, so yea eventually this entire solar system will die off but atleast we'll be on mars for like 900 million years before something starts happening lol
