The asteroid community recently gathered in Helsinki, Finland for the 12th Asteroids, Comets, and Meteors Conference. As this meeting showed, one of the hottest topics in asteroid science is the study of asteroid families.
As Cassini celebrates 10 years at Saturn, we're beginning to see its long-term observations of Saturnian moons bear fruit. A surprising new result: While Prometheus exerts control over the F ring and Atlas, Pandora -- long thought to be a shepherd of the F ring -- does not.
Will New Horizons have a mission after Pluto? Ground-based searches have failed to turn up anything that New Horizons can reach. Now Hubble is joining the search, but time is running out: a discovery must be made within the next two months.

This week the OSIRIS-REx team gathered at the Lockheed Martin facility in Denver to perform a “Design Reference Mission (DRM)” walkthrough. The DRM is basically the battle plan for OSIRIS-REx for accomplishing our goal of returning pristine samples from asteroid Bennu.
How scientists are working with CRISM, an aging but still exceptional spectrometer on Mars Reconnaissance Orbiter, to find the rocks where Opportunity's work will tell the story of ancient water on Mars.

The Twittersphere has been alive with speculation about a Gamma Ray Burst in the nearby galaxy M31. The problem is, there was never a claim of such an event, and it turns out that the tentative result that triggered this story was overstated.
Joseph O’Rourke summarizes a recently submitted paper on tectonic activity on Pluto after the Charon-forming impact.
A new meteor shower, the Camelopardalids, will be peaking Friday night/Saturday morning (May 23/24). Especially if you are in North America, you are well positioned to see what may (or may not) be a spectacular show. In either case, scientists will learn about a comet’s history, and you can have a fun night looking at the sky.

There is an asteroid threat and space debris workshop in Scotland this week that Planetary Society support helped lead to, and that will include two public lectures you can tune into live.
Earth and its solar system compatriots all have nearly circular orbits, but many exoplanets orbit their stars on wildly eccentric paths. Is our home system strange? Or is our sense of the data skewed?

What can a 45-year-old mission to the Moon tell us about a "meteorite" flying past a skydiver on Earth?
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
