Will we be able to travel to areas such as Mercury, Europa, Derlict ship near Saturn and explore, Mercury was shown with a ship flying towards it in the Venus sharttered trailer and we have one Europa concept art and the ship that was orbiting Saturns ring. Last thing in a video of E3 2013 I believe a dev was talking and he turned around at the beginning part and said all of that area was explorable is this still true?
