Cassini is going to make a major change to its orbit, getting much close to Saturn, setting up 20

Last week's Division for Planetary Sciences/European Planetary Science Congress meeting was chock-full of science from New Horizons at Pluto.

Alan Stern and the New Horizons mission team are the newest recipients of The Planetary Society's Cosmos Award for Outstanding Public Presentation of Science.

ExoMars Trace Gas Orbiter arrives on October 19, and it will deliver the Schiaparelli lander to its brief life on the Martian surface. Juno's headed into its science orbit, MOM has released science data, and New Horizons will finally finish downlinking Pluto flyby data.

The month of September begins with an annular solar eclipse visible from much of Africa on September 1. On or after September 8, we'll see OSIRIS-REx launch into a two-year cruise toward a rendezvous with asteroid Bennu. But September will close, sadly, with the end of the wonderful Rosetta mission.

This month we'll finally see JunoCam's first high-resolution images of Jupiter. We'll also see OSIRIS-REx making progress toward its September 8 launch. Both rovers are road-tripping at Mars, while ExoMars Trace Gas Orbiter has completed a major mid-course correction ahead of its October arrival.

One year after the New Horizons Pluto flyby, Emily reflects on its significance.

On July 6 at Lowell Observatory in Flagstaff, Arizona, the science team convened at the place where Pluto was discovered. Ted Stryk reports from the meeting.

Highlights this month include the impending arrival of Juno at Jupiter, the approval of extended missions for all of NASA's solar system spacecraft, and public data releases from Rosetta, New Horizons, and Cassini.

May 2016 will be yet another month of fairly routine operations across the solar system -- if you can ever use the word

January 24 was the 30th anniversary of the Voyager flyby of Uranus. Uranian moons have been on my mind ever since New Horizons sent us close-up images of Charon. On the occasion of the anniversary, Ted Stryk produced latest-and-greatest versions of the Voyager views of these worlds.

What's going on with our robotic planetary missions? In February I count more than 20 planetary spacecraft exploring six targets beyond Earth or cruising to new destinations.

Pluto is reluctant to give up its secrets. Last week at the American Geophysical Union meeting I attended sessions featuring results from the New Horizons mission, and most of the presentations could be summed up thusly: the data sets are terrific, but there are still a lot of Pluto features that have scientists scratching their heads.

For my first post on results from the Division for Planetary Sciences meeting, I'm going to tell you about Pluto's small moons: Styx, Nix, Kerberos, and Hydra, their bright colors and wacky rotation states.

I have a newly updated scale comparison graphic to share: all the round worlds in the solar system smaller than 10,000 kilometers in diameter, now with added Pluto, Charon, and Ceres.

Last week, the pile of New Horizons LORRI camera raw image releases included nine frames from a high-resolution mosaic on Charon. Together with the color MVIC view, they make a 3D global photo of Pluto's moon. Other recently released goodies include a global backlit color image of Pluto and the first image that resolves the tiny moon Styx.

Now that New Horizons is regularly sending back data, the mission is settling into a routine of releasing a set of captioned images on Thursdays, followed by raw LORRI images on Friday. The Thursday releases give us the opportunity to see lovely color data from the spacecraft's Ralph MVIC instrument. This week, the newly available color data set covered Charon.
