If We Landed on Europa

It Will be a Grand Day that day we see the surface of Europa ! Im All in for this ! Maybe by then they will have the Live forever pill developed ? :tu:

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.

What do we do if we find it and it takes 5000 years to get there.

We need to upgrade our spaceships!!

:yes:
