Objective Europa is basically a group, led by Kristian von Bengtson, that is in the early planning stages of sending astronauts to Jupiter’s moon Europa to look for life. One caveat: the trip is one-way with no hope of return at the end of the mission.
This is different from the Mars One idea of sending volunteers to the Red Planet as colonists without a return ticket, and paying for their upkeep by featuring the settlers on a reality show. Objective Europa appears to be purely self-sacrifice in the name of science.
The main reason for this extraordinary project is to look for life elsewhere in the Solar System. Especially after recent findings on Mars, Europa looks to be the most logical candidate for finding life in our Solar System.
