We have completed reconnaissance missions to all eight of the planets, and will soon perform surveys of two dwarf planets, Ceres and Pluto. Among the most compelling targets for future flagship missions are the solar system's moons. Can we use Phobos as a base from which to tele-operate Mars missions? Is there prebiotic chemistry or even life within the buried oceans of Europa, Ganymede, or Enceladus, or in the methane-ethane rivers and lakes on Titan? What could we learn about the Kuiper belt by studying Neptune's captured moon Triton? What could human explorers do on our own Moon using technology developed over the last 40 years?
These questions drive interest in future missions among scientists, but it's an uphill battle to sell decisionmakers on the value of expensive missions to objects that are "only" moons. For us to capitalize on the successes of our reconnaissance missions, it is essential to educate the public about the reasons that other worlds' moons are so exciting, and that they are worlds every bit as worthy of study as the planets.

NASA has been vague about when the new mission to Europa will launch. There's a reason for that, and it's not just orbital mechanics.
NASA just announced the science instruments that will be used to understand the enigmatic ocean moon of Europa. The mission is planned to launch sometime in the early 2020s.
I checked out the latest public image release from Cassini and found an awesome panorama across Saturn's rings, as well as some pretty views looking over Titan's north pole.

A study team at JPL will present their humans to Mars program concept at the Humans to Mars Summit and publish it as a peer-reviewed article in the New Space Journal.
NASA officials have asked their European counterparts if they would like to propose contributing a small probe to NASA's Europa mission planned for the mid-2020s.
Now that Cassini has returned to Saturn's equatorial plane, it has lots of opportunities to observe Saturn's moons. For about a week, Cassini has been taking regular sets of images of Iapetus, which I've assembled into an animation.
Scientist Stuart Robbins discusses dating the lunar surface is using impact craters.
The road to lower costs outer planet missions has been paved by NASA’s first two New Frontiers missions, the $700M New Horizons mission to Pluto and the $1.1B Juno mission to Jupiter. But can the cost of a mission to the outer solar system be cut to $450M, the limit for a Discovery mission?
