    I watch a lot of these sorts of talks (SVA of course, SETI institute, Cfa colloquium, etc.), and this was a really, really well done talk.

      They are literally building missions to Europa and Titan.
      Of course you can't find life because there are kilometers of ice above the oceans of Europa and Titan. Enceladus would maybe be easier by landing at the plumes. But it's also much further out and would still be insanely complicated, risky and expensive.
      We have not the faintest idea how to do this. And getting through this ice is only the most obvious problem there. Wereas Mars you can touch. And maybe learn how to do things.
      The same way they want to learn on the moon, how work on Mars later. You'd also need 2 or 3 consecutive gouvernments, sticking to any plan. It's not Nasa's idea to mess everything up every 4 years. You can maybe build and launch a mission to Mars in that time. You can NOT do that with Jupiter and even much less Saturn missions.

      @Trepang 412 FTL (faster than light) is largely a fantasy, if possible at all to create and survive in a "warp bubble" it's a long way off. Living anywhere but Earth is going to be indoor survival, not really living IMO.
      I fully embrace the push to become multiplanetary as an insurance policy for consciousness and Elon Musk will get ppl to Mars this decade I believe, but it's going to be rough going there for a long time. I don't see folks attempting to live off the land on Antarctica or zero rainfall Peruvian deserts which are 1 million X more habitable than Mars. I love forests, rivers, oceans, and LIFE in general, I wouldn't want to spend yrs one that desolate frozen hell hole Mars with nearly no atmosphere, a far off DIM Sun....on and on.

    His contention that in the ocean depths of Ganymeade that the pressure makes the water SOLID is false and does not hold water! At the bottom of the Mariana Trench, 11,000 KM, the water is close to the freezing point and LIQUID at 8 TONS per square inch! Yet, small fish and other marine life was observed! So how can Ganymeade, with its salty ocean and smaller than mars have more pressure than the Mariana Trench? He is obsessed with his Europa project, but Ganymeade with its Magnetic field and Oxygen offers better chance of finding life forms.

    "That, of course, was heresy and it got him in trouble with the Inquisition."
    Galileo was NOT tried for saying Jupiter had moons, or for saying anything else about space. He was tried for insulting the Pope. In a book length treatise, he made an utter ass of a character named "Simplicio" ("Simpleton") which everybody knew (and was intended to know) was a caricature of the then current Pope. Now what he was ridiculing Simplicio ABOUT was his view of the the nature of what we would now call the Solar System. But the Inquisition didn't care a whit about that.
    Nowadays, or at least when I was growing up, insulting important people was considered a civil right. Back then, it was an actionable crime.
