A week ago Saturday I decided -- against my better judgment -- to tackle this monster of a mosaic. I call it the

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.

The Juno mission posted a status report late Friday afternoon, indicating that they will not perform the originally planned period reduction maneuver during their next perijove (closest approach to Jupiter) on October 19. The delay changes the start date of the science mission and also all the future dates of Juno's perijoves.

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.

New scientific findings add to the evidence that Europa is spouting its liquid ocean into space. NASA has a mission to Europa in the works, but it wouldn't launch for at least a decade. Congress can make it faster, but it all depends on whether they can pass a budget this year.

Juno is on its second of two long orbits around Jupiter, reaching apojove (its farthest distance from the planet) today.

Beautiful new amateur work with 27-year-old Voyager data.

Cassini ends a year from today, which is sad. But the final year of the mission is going to be awesome.

A few weeks before the first Juno high resolution imaging, I decided to take a look at Voyager color images at various resolutions, with particular attention to high-resolution mosaics.

Titan's north polar lakes are well-lit by summer sun in these recent Cassini images. Image processing enthusiast Ian Regan shares his recipe for processing the longer-wavelength Titan images into visually pleasing

On August 27, Juno soared across Jupiter's cloud tops from pole to pole, with all instruments operating. NASA posted some terrific first results from several of the instruments today. And the JunoCam team released all 28 raw images taken during the close encounter.

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.

It is not easy to observe Jupiter’s moons as more than points of light with Juno, because Juno will never get very close to any of the moons, but as its orbit shifts there will be opportunities to collect data on some of the moons.

NASA announced this afternoon that Juno passed through its first perijove since entering orbit successfully, with science instruments operating all the way. This is a huge relief, given all the unknowns about the effects of Jupiter's nasty radiation environment on its brand-new orbiter.

Since a few days after entering orbit, JunoCam has been taking photos of Jupiter every fifteen minutes, accumulating a trove of data that can be assembled into a movie of the planet.

Juno’s science goals are to understand the origin and interior of Jupiter, focusing specifically on its atmosphere and magnetic field. Cameras can help answer some of these questions.

As it approached Jupiter from June 12 to 29, JunoCam captured an animation of the major moons orbiting the planet. The mission released a processed version of the animation on the day of orbit insertion, but took a few weeks to release the raw image data. I've prepared a page hosting all the raw data, and share a few processed versions.

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.
