Well since your hashtags don't lead me to believe you're trying to be funny, even though the amount of stupidity makes me suspect your goal was humor, I have a few facts to send your way: First of all please edit your post because I'm sure you didn't mean to repeatedly, idiotically refer to Europa and Titan as 'planets' in the title and post. They are moons, or celestial bodies, or natural satellites, or locations... but definitely NOT planets. Second of all they are gas giants. Any 'surface' that you could actually walk... or drive a sparrow on, is entirely hypothetical. The atmospheric pressure would crush to oblivion anything near any such surface that managed to survive the equally daunting gravitational pressure. The moons around these planets, however, are much more likely locations for the terra-forming and/or human settlement seen elsewhere in the Destiny universe. Third of all the moons you mention are actually quite scientifically interesting. I'd go into specifics but the bottom line is they're key destinations on our quest to learn more about life beyond Earth and the formation of planets and galaxies. What do I think? I think you're trolling. :-P
