It is just a thought experiment but this kickstarter campaign inspired me.
How awesome would it be if we would send an openROV to the (icy) moon of Jupiter? The capsule can crash in the ice and after some drilling the openrov can land in the hole and start discovering. By having a sattelite orbiting around Europa, it would be possible to gather the data. More here
If anyone starts a crowdfunding campaign for this, I would be happy to fund a part of it.
