Cassini-Huygens Reaches Phoebe 178
Anonymous Explorer writes "The Cassini-Huygens
probe is set to fly by the largest outer Saturn moon of Phoebe today. Cassini will be roughly 2000 km from the surface of Phoebe at 1:56 Pacific time Friday, June 11. Thats
pretty darn close. The newest
images of Phoebe are already thousands of times better than the previous ones taken by the Voyager
2 mission in 1981. Phoebe is interesting in that it maintains a retrograde orbit around Saturn. This has lead to the hypothesis that it is an ancient asteroid that has been captured by the gravitational pull from Saturn. Phoebe may provide some important insights into the composition of early building blocks of our planets. Phoebe was discovered in 1898 by American astronomer William
Pickering. As always, discussion about this mission can be found at
#cassini on irc.freenode.net."

Having scoured the web sites --- it's actually quite hard to find the information --- the probe is doing the close flyby at 2056 UTC (i.e. about two and a half hours from now). Assuming I've got the daylight saving compensation right, of course...

And yes, it is very possible that something unexpected will be seen. That would indeed give valuable insite. Even if it is just an ordinary hunk of rock, it will still give insight into the composition of other Saturnian moons and what to expect in that region of the solar system. Even as just a simple data point. It is expected that even more will be found, and frankly I look forward to visually exploring this world in a way that nobody until today has been able to see it like.
When the Voyager probes went by Io, there was no hint that it could possibly be showing active volcanoes, or be hinting at the distinct possibilities of seeing liquid oceans on Europa (admittedly buired under ice, but still there). I don't expect such a revelation with Phoebe, but you don't know. Perhaps a black monolith with proportions 1 x 4 x 9?

Space research is truly the last frontier. The knowledge derived from it lifts all humanity even if only from the perspective of giving us a glimpse into what all of us alive today will never see. Once a spacecraft leaves our planet it become research in it's purest form.
Fixing the roads may be important to you today but 1000 years from now will mankind get use from the fact that the local interstate had no potholes in 2004 or that a wealth of scientific information was gathered from Cassini?

3. Profit!!
Right now there is little to no incentive for a company like Lockhead-Martin to build system to land people on the moon and build a moonbase. Science is a terrible profit motive unless you can find practicle applications. And since we know the moon isn't made of cheese (which you can sell) or littered with diamons the size of footballs no company has this burning desire to go into space. Its too costly to make money at it.
So we are stuck with government ventures. I'm glad the US, Russia, and China push these things but I have no illusions about how this works. They are doing it because their is a small bet of prestigue and a good way to spend military for R&D without making it so obvious.
So until you find out that Pheobe is made of 99% gold or Mars has rubies the size of boulders or something else interesting there is little point ot privatizing space over having world governments fund it. Simply put, governments don't care about profits.

You find a public/private non-government entity that is willing to buy a moon landing system from LM and I'll conceed the point. Right now, there is no profit in deep space. Period. There is no modivation for investing capital in "noble causes". Its sad but very true.
Take a modern example: What profit is there in Cassini-Huygens? If you can figure that out sell it to someone and get rich and we all can send our space probes out there to take a close look at Saturn.
