Incredible challenges and possibly certain death await those "lucky" enough to take part in Objective Europa.
ESA scientists are testing projectiles that could punch through the icy moon's crust and get at it's liquidy innards.
NASA has organized a team to discuss a future Europa mission to discover if the Jupiter moon is potentially habitable.
Of all the places in our solar system (besides Earth) where life has a real shot at being lifeish, Europa is probably at the top of the list. This is why, in defiance of the warnings in 2010: Odyssey Two, NASA may send a pair of landers to Europa in 2020.
It's possible for an asteroid impact to send rocks from other planets to Earth, which is how I got myself a Mars rock and why this guy thinks he's found aliens. New simulations show that it's possible for things to work in the other direction as well, sending rocks from Earth out into our solar system and on to interstellar space.
