Edit: Yes people! the moon! not the continent Europe! Don't expect NASA in europe.... and maybe the picture below will help?
We've known for a long time of a large liquid ocean under europa but now there is very strong evidence that not only is there water under Europa but salt water. I'm very glad that we are dedicating more time into understanding mars, but i think it's time we start developing a craft that will fly to Europa since there is a much bigger chance we will find bacterial life on Europa than Mars and if anything that is the most important discovery of all time
Its time to visit Europa! who's with me?
