Hello, this debate is about if we should research the Jupiter's Galilean moon Europa, more then we do now. And of course, we should put more effort to research other Galilean satellites. Con should present a reason why we aren't supposed to research Europa more, or even not at all.
Good luck to Con.


Hello, I'd like to thank Pro for bringing up this debate, I hope it will be interesting.

First, I'd like to ask for the reason why you think we should research Jupiter's moons more than any other body in the solar system more than we do presently. I understand Europa is the best candidate for life to exist outside Earth, which makes it the most exciting body to learn about however I do believe we should focus on researching more on Mars at this time especially when a plan exists to colonize Mars.

Saturn's moons such as Titan should take priority over any of Jupiter's because this moon may be more hospitable than Mars, and colonisation will greatly benefit mankind

I look forward to hearing your response
Debate Round No. 1


A nice Guten Tag. And thank you for joining my debate.
So now lets begin.
First of all, we know that Europa is one of the top high objects with potential life. However it has a lack of research to be honest. The Pioneers,Voyagers and the Galileo spacecrafts have flyby and studied the amazing satellite. Studies have also been performed by other missions, like New Horizons and the Hubble ST, but weren't focused on it. But that's it.

I totally agree that we've to research Mars, because its currently the top potential or at least has habitated life on itself. I didn't mean to get focused off mars, as a matter of facts, we should and already do many different missions at the same time. Luckily there will be missions like the Jupiter Ice moon Explorer, but far in the future (cca. 2020s). Meanwhile many past missions were cancelled like the JIMO, Europa orbiter, Russia"s Europa Lander and many more, but all were cancelled.

Europa is a astrobiological treasure, for now. Its a fact that tidal-flexing causes warmth (caused by Jupiter),so there is an large H20 Ocean beneath the Ice Crust. There are also water plumes discovered in 2013, and are larger than those on Enceladus. The poor atmosphere only 10x as big as that of the moon at day is mainly composed out of Oxygen. There are some minerals (especially phyllosilicates), carbon and silicate rock. All are great for life, silicon is also good as it can replace carbon. Black smokers- like phenomena in the deep ocean can help the special chemosynthesis for life. But Europa has many materials that are fundamental to our organic composition. So maybe Europa has "ET Life" that can pass similar Synthesises that we do on earth and maybe on Mars. If these species had a similar Biochemistry that we do, then there is a small chance that Earth"s life started on Europa, and came to us by Ejectas. Or that life started somewhere else and came by ejectas to all today/past potential objects Venus,Earth,Mars,Titan & Europa. The main difference between all species if all objects had the same ancestor, were its evolution. Check ALH84001, that contains amazing fossils. If we find find similar species on Mars or Europa or maybe even somewhere else, then this is a sign that our Biological "LUCA or LUA" had to come from somewhere else.

Missions can be performed, and they probably were if another cold war started. The yet simplest idea would be to analyse the depth of the icy crust and to send Nuclear cryobots that would release AUVs, that are already used today, especially in the UK and Norway. There are also ideas for sending a lab just like Curiosity rover to analyse if there are any fossils or signs of life forms in the ice. But we would have to seriously sterilize any mission, so that our Earth species wouldn't become invasive, we also need to do that when we"ll go to mars.

So Europa has many pluses and missions are possible and since its such a high potential for life, it should deserve a better research.

Good Luck.


Good day to you,

I didn't realize the missions have been cancelled due to a lack of funding and a lack of technical developments, I see now why you think we should research Jupiter's moons more. It is a shame a deal has not been finalised by the Japan Aerospace Exploration agency, the Russian Federal Space agency, or NASA.

Europa and Titan are of most scientific interest. However Titan is the second largest moon in our solar system, being only smaller to Jupiter's moon Ganymede, but Titan has a thick atmosphere and is mainly composed of water ice and rock. The climate of Titan would be great to study because there is methane cycle rather than a water cycle [ 1] and the atmosphere has a similar 80% Nitrogen like Earth

There is certainly a lot we can learn about Titan. We have studied its atmosphere and greenhouse effect already which helps us to learn a lot about our own, but could there be an alternative type of life? Researchers have worked with what they know exists there and have made a model blueprint of what a cell could look like, so it would be interesting to find non-water based life. [2]

If we want to learn more about water based life we should really be searching for life in our own oceans. 86% of life on Earth is believed to be undiscovered and many species are going extinct [3]
