Speaking of which, when is the launch of the Europa landing probe schedualed for? I'm pretty sure that NASA is building one....

It is not just what you said above. Europa has a magnetic field similar to Earth's that has some of the same characteristics. Europa's topographical features also give hints and evidence to support this.
Cassini, when passing through it, discovered that 65% percnet of Enceladus's atmosphere was water. Water vapor. So yes, Liquid water probably exists on it's SURFACE.

I think that it might have been put aside in the budget cut. Not sure, though.

Doubtful Retic, the surface is too cold to support LIQUID water. It would exist undernearth the surface, which is ice crust.

No, actually the geyesers create the water, which turns in to water vapor. It isn't nessecarily on the surface, so much as vapor. It exists very close to the surface as liquid water, though.

Given the current political climate, it may be awhile before NASA gets funding for new projects. A shame, but there it is.

You said Europa before, but you're talking about Enceladus right?

No, spectroscopic analysis from a distance can confirm water or ice or other chemicals--but only on surfaces. The interior of Europa doesn't emit anything to analyze.

But it does heavily hint at it. If there's, water, methane, ammonia, and hydrogen, it's quite likely that there's life. LinkPosts: 1947 | Registered: Aug 2002

You do realize how cold it is there, right? It's quite quite cold. The most bizarre thing to me is that the temperature at the pole is warmer than at the equator. On the Nasa page they said it was like finding out Anarctica was warmer than the Sahara. What could be causing that anomaly?
One part of me wants to think of protozoans huddling around a post-apocalyptic nuclear waste dump. But it's anyone's guess at this point. It's super thrilling that they've found it. I can't wait until we actually explore the solar system! How has humanity resisted the urge for so long? It's mysterious and it's huge and it's where we live! Don't you guys just want to know what's there? Are we going to stay on this one little blue marble forever?

I hope not, Tatiana. That way, those of us with our ignorant, small minded belief in a simple book can leave this world and fly to a better one.
Pun intended, but being serious too.

Hey Advent, check out this part of the Forum Users Agreement you had to accept befor creating a user on Hatrack (the bolding is mine):

See this is a thing that rankles me. If you hit the "Add Reply" button with a post that has this sentence in it (or one like it), guess what? Too late, you aren't polite. Advent you aren't the only one (heck, I've done it on occassion), just the most recent example I've read.
You could have left it out, and actually BEEN polite, rather than "just trying".
