Europa Up Close

Europa shows strong evidence for an ocean of liquid water beneath its icy crust. In fact, it could have all the ingredients needed for life as we know it. NASA’s Europa Clipper spacecraft will perform dozens of close flybys of Europa to determine whether there are places below the surface that could support life. Take an in-depth look at Jupiter’s icy moon.
