Europas has too much radiation from Jupiter to colonize, Ceres on the other hand is a far better choice, is closer and has lots of water.
What about Titan? I thought that might have life or at least water. Many mysteries are still out there! We need NASA back! Arise America! We don’t want Chinese driving that car we left on the Moon! Now that we found water there (on the dark side) we can support a base—from the moon—the rest of the planets! Then-—into deep space.
