I just love photos of Earth from planetary missions -- especially if they manage to get Earth and Moon in the same shot, as Hayabusa2 did on November 26.

Secretive spaceflight company Blue Origin flew its New Shepard launch vehicle to the edge of space, deployed a suborbital spacecraft and returned the spent booster rocket to Earth for an upright landing.

If you were to download the entire catalog of photos taken at Saturn to date by Cassini and then animate them like a flipbook, how long would it take to watch them all pass by? The Wall Street Journal's Visual Correspondent Jon Keegan has your answer: nearly four hours.

Akatsuki is finally approaching its second attempt to enter Venus orbit, on December 7; let's all wish JAXA the best of luck! And PROCYON, whose ion engines have failed, is still an otherwise perfectly functional spacecraft that is taking photos of Earth and the Moon as it approaches for a flyby.

On October 28th, the Cassini spacecraft flew through the geyser plume of Saturn's moon Enceladus. But Cassini was not the only spacecraft operating in the solar system that day.

There have been several important pieces of news about European missions in the last month: Rosetta's fate has been determined; ExoMars Trace Gas Orbiter's launch is slightly delayed; and they have selected a landing site for the ExoMars rover.

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.

A few days ago, Dawn officially released the first big pile of data from the Ceres mission phase. Thanks to the public release, I can show you color global portraits of Ceres.

A couple of days ago, Cassini flew past Enceladus for its 20th targeted encounter. Cassini has seen and photographed quite a lot of Enceladus before, but there's still new terrain for it to cover.

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.

A cache of more than 8,400 unedited, high-resolution photos taken by Apollo astronauts during trips to the moon is now available for viewing and download on Flickr.

Last Friday I posted an image containing 18 samples of terrain, all shown at the same scale. Were you able to figure out which square was which? Here are the answers.
