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.

Several announcements for proposed missions to Mars and on the planning for a NASA return to Europa that highlight the contrasts in planning missions for these two high priority destinations.
NASA has selected a Planetary Society proposal to study accommodation of the Society’s LIFE (Living Interplanetary Flight Experiment) biomodule on NASA’s Asteroid Redirect Mission (ARM).
Are we alone in the universe? This month’s National Geographic cover story takes a look at the question, and I weighed in on the subject.
There's an old saying about Washington, D.C.: it’s a small town, based on relationships. We are establishing very good relationships with members of the U.S. Congress and the Administration. Three of us made the rounds recently, going from one Congressional Member’s office to another to support planetary exploration and a mission to Europa. Our team included Casey Dreier, our Director of Advocacy; Bill Adkins, our lobbyist in Washington; and me.
A few people think that when it comes to the Moon, because we’ve “been there, and done that,” there is nothing new left to discover. But that viewpoint could not be farther from the truth!
The Planetary Society strongly supports NASA's asteroid initiative, including the goal of redirecting an asteroid to the vicinity of the Moon. But an independent cost estimate is needed, and needed soon.
For the last two years, NASA has been the shy partner refusing to get on the dance floor, and Congress has been the aggressive partner insisting on a dance now. The dance is the continuing attempt by Congress to have NASA commit to a mission to explore Europa, and NASA’s attempts to delay a mission well into the 2020s.

Earth's brilliant colors shine above the drab lunar horizon in this new "Earthrise" photo from the Lunar Reconnaissance Orbiter. An animation that accompanied the image release helped me to write an explainer on how pushframe cameras like Lunar Reconnaissance Orbiter's Wide-Angle Camera works.
Our Advocacy Program provides each Society member a voice in the process.
Funding is critical. The more we have, the more effective we can be, translating into more missions, more science, and more exploration.
