NASA Laying Foundation For Jupiter Moon Space Mission
coondoggie (973519) writes "NASA recently began laying out the groundwork for the technology it will need to fly an unmanned mission to Jupiter's intriguing moon Europa. Scientists say Europa — which orbits the planet Jupiter about 778 million km (484 million miles) from the Sun — could support life because it might have an ocean of liquid water under its miles-thick frozen crust. NASA said in December the Hubble Space Telescope observed water vapor above the frigid south polar region of Jupiter's moon Europa, providing the first strong evidence of water plumes erupting off the moon's surface."
It's way the fuck out there, bathed in EM radiation, and goddamned cold. Mars is right next door and practically balmy in comparison.
Is it just my observation, or are there way too many stupid people in the world?
but it doesn't have oceans.
AND, there are lots of other interesting moons out that way. good to establish a precedent that this far out exploration can be done.
My God can beat up your God. Just kidding...don't take offense. I know there's no God.
That is not the reason. The reason that there has not been a dedicated Europa mission is because it will be a very expensive mission and the money is not available. The reason that the money is not available is because the US government does not want to give NASA the required funding. If the US congress offered to give NASA the money, and kept the funding going for the 15-20 years that would be required to do a long-term exploration of Europa, then NASA would jump at the opportunity. There is also a matter of rivalries between JPL and various NASA centers, but a reliable funding stream would go a long way towards resolving those.
Just because you are paranoid does not mean that no-one is out to get you.
It seems a lot more feasible to me to build a permanent off-world habitat on Europa beneath the water, than to build one on Mars. The ice and water would shield you from the radiation normally absorbed by Earth's atmosphere and ionosphere. You can extract oxygen easily from water using known processes. And there is no need to MAKE water since it is everywhere. Furthermore, we are already well-versed in making underwater habitats and the habitat would be easily testable here, so there are fewer unknowns.
You would not even need to sink the habitat very deep to protect from the radiation, it could achieve neutral boyancy somewhere in the middle of the water column, and then rotate itself in the water to achieve 1G via centripetal forces.
We'll never get through the thick ice layer.
We'll never be able to fly
We'll never be able to go into space
We'll never be able to land on the moon
We'll never be able to have civil and informative political discussions....
Ok, the 4th might be true, but 'never' and human ingenuity shouldn't be lumped together very often.
People in cars cause accidents....accidents in cars cause people
"Why don't the US ask Russia which one they're going to, and beg for a lift"
One reason might be that the Russians have never (that is - not ever, not even once, not even attempted) launched a mission to the outer planets, neither have the Europeans; only the USA has shown the capability, several times over, starting in 1972 with Pioneer 10 and most recently Juno to Jupiter in 2011.
The US has plenty of unmanned launch capability and does it all the time with Atlas's and Delta's and Falcons. The US has a temporary lapse in human capable launch vehicles and spacecraft which is unfortunate, but that is being remedied on multiple fronts and to extrapolate that to, "the US should ask Russia for help to the outer planets" shows a complete ignorance of the history and state of outer planet exploration.
