Beneath the ice in the salty ocean4/21/2018 Meet Europa. It is the smallest of Jupiter's four moons which were discovered by Galileo. Europa is smaller than Earth's moon(~65%), but larger than Pluto. It's surface is a thick layer of smooth but scarred ice, obscuring an ocean underneath which is able to remain liquid due to the tidal flexing between the moon and the planet. Scientists think that there is an ocean of salty water located just beneath the surface due to a special magnetic field that Europa has, which was measured by the Galileo Mission. NASA's preliminary plans for reaching the saline moon, The Europa Clipper, could allow us to touch the icy surface as soon as the 2030s, at the same time that we are hopefully in the beginning stages of getting people to Mars. The reason Europa is so interesting is because that liquid ocean is very similar to sub-glacial lakes that have been found on earth and it is thought to be old enough for life to have evolved there. In the timespan of roughly 400 years, we could go from discovering a celestial body to having found life on it. That is truly amazing and a credit to all of the people who have built made it a possibility, many of them working on thankless tasks but for an amazing cumulative effect. Of course there are many people today who suggest that such missions into space are a waste of money, resources, time. We have a collective legacy as explorers, often fraught with the terrible actions of colonialism, but this is a legacy that we should continue and improve as we extend our reach into outer space. With reasonable certainty we can say that life exists outside of our planet, but without finding evidence of it we can never be absolutely certain. As we venture forth, it will be a search for more than life but for scientific discovery in general which will ultimately give us insight into our own planet, about the origins of our solar system, the galaxy and our universe. Research and development created for these ventures will also give us new technologies that could make life on Earth better and more sustainable. Trying to see, to understand and to touch ever farther beyond our planet is a heroic task that will ultimately aid the survival of our species. Is the truth still out there?
