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.
@@markmitchell450 Yes we need to get crack'n, get our priorities straight damnit. NASA has NO BIZ building rockets anymore, nough of the jobs program and start building probes like crazy.
@Trepang 412 Right. Probably be a private program at this rate. Best to shut NASA down permanently with in the decade. They've outlived usefulness, just a waste of money now.
@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.

Did life originate on Earth only once? Could there have been more than one LUCA? More than one tree of life? If life could have originated more than once, must it necessarily have been DNA/RNA based? Could there have been another means of heredity and evolution?

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.

Hi Mark. I wrote an entire book on the topic and challenged 3,000 of the highest ranking educators from across the country to challenge or debate me on any level. 3,000 educators refused to challenge me, as the evidence I render is very simplistic and overbearing. Drop your email address and I will be happy to send you a free copy. It will teach you more about cosmological science than any book you've ever read by the mere application of common observations and commonsense.
Zzz zzz,zzzzzz. What gets me is these guys know what the core is made of, how much salt ECT. They know everything about these moons but can't figure out if there is life. Bull stuff.
Is this guy an Alex Filipenko clone? Or is it a case of having the same JPL-speak elocution teacher? As for the irritating slurping on a [PLASTIC} bottle of water...something Freudian about that. Get weaned!
I think he mentioned this, but Europa life would be a different sort of discovery than Mars life since Mars life might be related to Earth life. Bacteria could have been passed back and forth between Earth and Mars via meteors while both planets had surface oceans.
@@Kalumbatsch That's certainly not impossible. But it seems-given Jupiter's gravity and radiation, and the thickness of ice-that life transfer between Mars and Earth was much more likely than between Europa and Earth.
So the possibilities in this solar system so far are Venus, Mars, Europa, Enceladus, Titan. Possibly Ceres maybe even Pluto. How arrogant we are to not see the writing on the wall that there are all these worlds with the chemistry of life all over and believe they are all dead worlds
"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.
Damn it, send more probes to Europa then! If Nasa has no budget, we can make a world-wide donation, all developed nations‘ citizens can donate 5 usd on average. Here in Switzerland its the price of one espresso. This will be some 10 billion + private angel donators = 15 bill. Should be enough, no?

Oy, Fracnoy's habitual rising inflection at the end of many statement is really irritating.
If there is life or had been life on one other planet or moon in the solar system, then life is common and expected in the galaxy.

I think he mentioned this, but Europa life would be a different sort of discovery than Mars life since Mars life might be related to Earth life. Bacteria could have been passed back and forth between Earth and Mars via meteors while both planets had surface oceans.
Or maybe the common ancestor of all life on Earth lived in the oceans of Europa? It has been spraying out ice particles for billions of years..
