In Scientific American Magazine, (May 2023 issue), I read that space exploration is focusing on a few of the many moons of Jupiter, such as Europa, because water was spotted by the Hubble Space Telescope. Water, of course, may mean life.
It seems, to explore moon oceans, a moon walk might not be enough. And to get there, it will take eight years for the six-ton JUICE ( which stands for Jupiter Icy Moons Explorer) to get there.
