Major Moons

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.

Enceladus huffs and puffs: plumes vary with orbital longitude

Posted by Emily Lakdawalla on 2013/12/11 07:22 CST | 2 comments

In which I finally get around to writing about a paper published last August: Enceladus' plumes sometimes spout more and sometimes spout less, depending on where Enceladus is in its orbit. This discovery was enabled by Cassini's longevity at Saturn, and we'll be able to follow up on it, as long as Cassini is allowed to complete its mission.
