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.

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.
Discover the Universe including the Big Bang, dark matter, dark energy, galaxies, life and more in this video of class 13 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
New Horizons team member Simon Porter reports on the state of the mission and Pluto system science from the recent science team meeting at the Applied Physics Laboratory.
The House revealed details of its draft NASA budget today, including an increase of $170 million to Planetary Science above the White House's request for 2015, putting it within spitting distance of our goal of $1.5 billion.
Budget season is in full swing in Washington, D.C., and we're starting to see indications of how NASA will fare this year. I have to say, things are looking pretty promising.
LADEE ended its mission as planned with a crash into the lunar surface on April 17. Just days prior, it turned its star tracker camera toward the lunar horizon and captured a striking series of images of the lunar sunrise and zodiacal light.
What can a 45-year-old mission to the Moon tell us about a "meteorite" flying past a skydiver on Earth?
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.
