NASA's Cassini spacecraft is set to embark on its closest and most daring flyby of the moon to date.
Thought to be home to a subterranean ocean of liquid water, Enceladus remains one of the most promising places to look for evidence of extraterrestrial life within our own solar system.
One of its most unique and interesting features is its geysers which periodically spew water vapor, ice grains and unstable chemicals in to the atmosphere at speeds of up to 1,360mph.
Now in an effort to learn more about the composition of these materials, Cassini will be swooping down to within 30 miles of the moon's south pole on October 28th so that it can collect samples.
"This incredible plunge through the Enceladus plume is an amazing opportunity for NASA and its international partners on the Cassini mission to ask, 'Can any icy ocean world host the ingredients for life?'" said Cassini program scientist Dr. Curt Niebur.
But philosophically I don't think it would be alien life. Outside of our solar system and around another sun? Then hell yes. But in our solar system, we are all children of our sun..we just haven't found them yet.

Being only 500 km's wide, it seems unlikely that life will be there, if there is, it would be more than interesting to see what might develop under such different conditions. Can't imagine anything bigger than a microbe at best.
It might be alien or it might be Earth life that has adapted to conditions there (from meteoric "infection"). I think it is probably sterile (there is no evidence, just possibility), but if it is there I would say both of these possibilities have about equal (small) probability. That is on the assumption that simple life is not something that happens practically everywhere conditions permit. This is by some thought to be the case, but I would't dare try to assess it now.
I hope evidence is found to support that there is life there. The main problem is: money. Even if NASA (and Co) went "Yeah, there is ingredients for life there, but we can't 100% confirm there is life without going down there" then that would be the end of it. NASA and Co have no funding to mount that kind of expedition. They DID have plans, but they were shelved in favour of Mars. Which, based on what we've found so far, isn't too bad a decision. However I think the earliest exploration of "potential life" moons is 2035 (and then 5 years travel based on current tech, maybe EMDrive will be wor... [More]
NASA and Co have no funding to mount that kind of expedition. Not actually true. NASA's budget is bigger than that of Russia's Roscosmos, Europe's ESA and China's CNSA combined. They DID have plans, but they were shelved in favour of Mars. Also not true. NASA has funding for a mission to explore the surface of Europa. Europa should be being investigated by rovers. Rovers are an extraordinarily bad idea. Since any life will be in the ocean below the ice a rover is unlikely to find anything. A system for drilling through the ice and a submarine are what is needed. It's the most likely to hold an... [More]
I'm sure one day NASA will find life on another planet, just not as we know life. Oh no doubt it's out there, but I doubt it is NASA that will find it.
Just a reminder that the Enceladus "deep dive" occurs today! http://earthsky.org/space/does-enceladus-support-life-7-key-facts?utm_source=EarthSky+News&utm_campaign=1f5a27b312-EarthSky_News&utm_medium=email&utm_term=0_c643945d79-1f5a27b312-394012957
