We can handle Mars there's no doubt about it. But all evidence points to Mars being a completely dead planet with a thin ozone with soil incapable of growing anything food wise.

A man mission to Mars in my opinion is irrelevant. Let's send resources and probes to a world that more than likely has water and might even have life.

@XboxFun The more places we can go the better understanding we will have about the whole universe we will never be able to go to mars they found out that humans would never make the trip home due to radiation Darpa and Nasa are working together to make a humanoid robot that will go to Mars and get things ready for humans.

Europa has better signs of life
Europa has water
Europa has an atmosphere closer to Earth's
Europa can sustain life just as well as any planet

Mars is dead
Mars has no water for those river beds
Mars has no ozone and is pummeled with radiation from the sun
Venus is close too, doesn't make it habitable though

Think of all those poor organisms being geysered out to their doom.

Icy surface is actually a great insulator and indicates great possibility for liquid water to exist at a certain depth. Also Europa is know to have a heated core( due to the friction generated by the gravitational push and pull of its parent planet). So the heat from the core may cause the ice( at a certain depth) to melt.It also suggests the possibility of volcanic activity.

These facts were already known before the confirmation. But none the less it is great news.Who knows maybe someday, in the future mankind may find itself in an underwater city somewhere in Europa.
