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.
In the two months since I last checked up on the Rosetta mission, the comet has heated up, displaying more and more jet activity. Rosetta completed very close flybys on February 14 and March 28, taking amazing photos. But comet dust is making navigation difficult, so the mission is now keeping a respectful distance from the comet and replanning its future path.
New Horizons took its first color photo of Pluto and Charon, while Dawn obtained a 20-frame animation looking down on the north pole of a crescent Ceres.
PROCYON (PRoximate Object Close flYby with Optical Navigation) is a microsatellite that launched on December 3 as a secondary payload with Hayabusa2. The mission has now selected their asteroid flyby target -- a binary asteroid named 2000 DP107 -- but is reporting a problem with their ion engines.
Since I last wrote about Curiosity drilling at Pink Cliffs, the rover has visited and studied two major sites, drilling at one of them. It has also suffered a short in the drill percussion mechanism that presents serious enough risk to warrant a moratorium on drill use until engineers develop a plan to continue to operate it safely.
What is the solar system moon with the densest atmosphere? Most space fans know that the answer is Titan. A few of you might know that Triton's is the next densest. But what's the third? Fourth? Do any other moons even have atmospheres? In fact, they do; and one such atmosphere has just been discovered.
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.
At last week's Lunar and Planetary Science Conference, the MESSENGER team held a press briefing to share results from the recent few months of incredibly low-altitude flight over Mercury's surface. The mission will last only about five weeks more.

Cassini recently took a long, high-resolution movie of the F ring, catching a view of its ringlets, clumps, and streamers, and two potato-shaped moons, Prometheus and Pandora.
Three talks on Tuesday at the Lunar and Planetary Science Conference concerned the first results from Dawn at Ceres. Chris Russell showed a map of "quads" with provisional names on Ceres, Andreas Nathues showed that Ceres' bright spot might be an area of plume-like activity, and Francesca Zambon showed color and temperature variations across the dwarf planet.
