Where in our solar system should NASA focus future missions?

Claim: NASA should focus future missions on Europa.

Evidence: Europa, one of the moons of Jupiter, has been recently focused due to the possibility of hosting life. “One of Jupiter’s moons may have plumes, or geysers, spraying clouds of water vapor. In 1997, NASA’s Galileo spacecraft flew by Jupiter’s moon, Europa, to collect data.  Now, a new report suggests that the spacecraft flew directly through a watery plume. The finding is raising hopes for signs of life outside Earth.” “NASA’s Hubble Telescope had spotted repeated evidence of plumes.”

Reasoning: In human’s perspective, water is needed in order to have a hospitable envirnment for life. NASA’s Hubble Telescope had spotted signs of water. This shows the possibility of hospitable envirnment where living creatures might develop. This would tell human beings that humans are not the only living creature in this universe, showing chances of more life throughout this gigantic universe.
