Its always worth the Shot - n - the Dark ! Afterall One never knows what may be under that Ice? I say we could go for it ! Maybe we can tow it back to earth and melt it for drinking water and water our dry lawns? :tu:

If there is intelligent life out there, Donteatus, I have NEVER wondered why it stays AWAY *heavy sigh*.  Thumbs down for towing :cry: lol. I just like to look and imagine a la Ray Bradbury.

Edit to add: Waspie, can I steal this and use it when I figure out how to add sigs at the end of my posts "reality does not care one iota what we believe, it just is what it is."  ?

Don't forget most Scientists believe where there is ice, there is life, so being optimistic, thats what I expect to find in the water on Europa. Life of some type.

Generally where there is water, there is life: on earth. However it may be we are unique in the solar system, the galaxy, the universe. Essentially evidence to the contrary is based on statistics and the hope that if conditions are similar to earth, there should be life. But the fact is we do not know.

If life exists on Europa and it has the same chemical building blocks as earth life, then we still do not know if life exist outside our solar system, because there would be the remote possibility that this life was somehow seeded from the earth to Europa, say by meteor impact.

If the chemistry is completely alien to life as we know it, then I would say the possibility of life outside our system is more likely, but again it unlikely it will be provable in our lifetime.

Are they absolutely sure that the surface is frozen water ?,and not a concoction of harmfull chemicals.

LOL I used to think like that, now I'm 43 and I still feel young....maybe that's why I look a lot younger....it's the attitude, Bavarian Raven, it's how you feel...believe you me.

If they are sending a rover by 2030 then I have hopes we'll find out whilst still alive.

Scientists believe the ice core to be made of hydrogen and oxygen, just like ours,H2O.
The oxygen reacts with the radiation from Jupiter and they believe this reaction is the key to life on Europa.

LOL! They will need more than that...the day we start getting pics from Europa I'll be glued to the telly!!!....or whatever we'll watch our programmes on in 20 years time...lol

If life exists on Europa and it has the same chemical building blocks as earth life, then we still do not know if life exist outside our solar system, because there would be the remote possibility that this life was somehow seeded from the earth to Europa, say by meteor impact.

There is a hypothesis, called pseudo-panspermia (or soft panspermia) that says that the building blocks for life, the amino acids, were carried to Earth on comets and asteroids early in Earth's history. There is a growing body of evidence that suggests complex organic molecules exist on such bodies.

If pseudo-panspermia is correct then most rock worlds in the solar system should at least have the b=necessary building blocks for life. Moreover, because astronomers believe that solar systems generally form the same way then comets and asteroids should be common in other solar systems. The chemistry that formed these organics is likely to occur in other solar systems. If the building blocks for lie are common then simple life should be common too.

There is a hypothesis that goes one step further, the original panspermia hypothesis itself. This suggests that not only were the building blocks of life created on asteroids and comets but life itself started there. If this is the case then wherever the conditions are right in the solar system then we should find life. Again, because the same processes are occurring in other solar systems, if panspermia is correct then life should be common throughout the galaxy.

Of course panspermia and similar ideas are only hypotheses, they may be incorrect. If that is the case and life occurred independently on Earth and one or more other worlds such as Mars or Europa (Ganymede, Titan and Triton can not be discounted either) then this would also lend weight to the idea that life is common place. If it occurred more than once in our solar system it would seem more likely that it is common place through out the galaxy.

The final option is that we don't find any signs of life elsewhere in our solar system. If that is the case then it doesn't really prove much. it could be that life is rare and the Earth is an exceptional world, it could be the life is extremely common and the solar system is unusual because life occurred only once here or it could be that the solar system is totally normal and one planet with life is the galactic average.

It is because there are so many questions unanswered in one of the most fundamental questions in science, "are we alone?" that we must continue to explore not only Mars and Europa but asteroids, comets and other planets and satellites.

The surface of Europa will be interesting, but it's what is underneath the surface that really holds all the secrets.

Nasa said the Milky Way Galaxy may be home to approximately hundred billion sun like stars and maybe 2 billion Earth analogue planets....I strongly believe at least one of them could have the signals for life (O2 and H2O).

We may not find the 'aliens' we are looking for, but we might find another Earth...and the way things are going here, I think we need to find it.
