[quote]Thursday at 2 pm Eastern, NASA will announce some exciting new findings about “oceans beyond Earth.”
The space agency is being coy about the fine details. We do know the announcement will involve data from the Cassini spacecraft (which has been orbiting Saturn and its moons and is set to crash into the planet come September) and the Hubble Space Telescope. The announcement will stream live on NASA TV come 2 pm, and you can watch right here.[/quote]

The discovery is that Enceladus water plumes contain hydrogen, which comes from similar ocean floor vents as what we have on Earth, and those vents have a good chance of being an energy source for microbial life on Enceladus just like they are on Earth.

Let's send probes.
Theoretically, if warm enough down there, we could inhabit such a planet via under-water structures. The added bonuses of this being that we'd be protected from solar radiation to a similar degree to being underground, but with the added benefit of being able to move and build easier in the medium. The only struggle is breaking through the ice on top in a reasonably permanent way to allow for off-world transport of people and resources.
A water ocean is a huge deal and I'm very excited to hear more about it tbh.
Having water on planet solves the need for oxygen via electrolysis, and with such a large amount of water it's not like we'd be having to worry about harvesting ice or bringing oxygen assuming the system worked well. And thermal power from the vents would be a good, long-term solution for heat and power.

What is crushing pressures for 500, alex?
[QUOTE=wallyroberto_2;52099102]What is crushing pressures for 500, alex?[/QUOTE]
I'm pretty certain the water pressure won't be as bad as earth's oceans considering both of those moons have a 1/10 of Earth's gravity.
Plus we could just inhabit right below the ice layer and build structures/domes suspended/anchored to the ice shell considering it's harder than granite whilst still getting the benefit of radiation shielding from the ice.
[QUOTE=wallyroberto_2;52099102]What is crushing pressures for 500, alex?[/QUOTE]
What is, this moon isn't near as big as earth for 1000? You don't have to build on the bottom either duder. There's this convenient ice roof going on there. Plus the ocean isn't just this solid hole all at maximum depth. There's probably quite a few places with sea floor in areas above crush depth, we have entire mountain ranges on earth below water so uhh, yeah.
How long would it take to actually reach Enceladus with a probe? I would imagine years?
I know there are certain windows you have to launch within for these things, and knowing our lucky as Earth recently, we wouldn't have an opening until like 2080 or something dumb...

Ocean world is cool and all, but what about battle world?
What if we get over there, dive down, turn on the ligths and OHFUCGGG-

Let's go there! If we can find lifeforms there we won't feel guilty anymore about poluting the earth! As if the guilt even stopped us from destroying the environment.
Losing is fun!
Guilt doesn't stop us, Greed drives us

We haven't even left earth and HAL5000 has already gone batshit

Humanity is resilient. We'll survive.
NASA's new thing is all about manned missions, and that can be seen in the SBIR grants they've been giving out to companies (our company is one of the ones riding this wave tbh). I'd bet on seeing a lot of solicitations relating to this discovery in next year's round of SBIR/STTR solicitations, so that should be pretty exciting! I'm recall a plan circulating now with the folks at Marshall to launch a big satellite carrying several nanosatellites to the Saturn system, at which point the big satellite will deploy the smaller nanosatellites. Several of these have small maneuvering thrusters like ion drives, and I know of one project that aims to harpoon the fuck outta Enceladus, collecting ice core samples. Not sure how they plan to retrieve the samples, though...
