There are no spacecraft at Uranus or Neptune, and there haven't been for 30 and 25 years, respectively. So we depend on Earth-based astronomers to monitor them, including Damian Peach.

The Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) is almost a silent star at Mars. The latest MRO data release brought the total number of available CTX images to over 70,000, covering well over 90% of the Red Planet at a stunning resolution of 6 meters per pixel.

For months, Dawn has been steadily, methodically sharing dozens of images of brand-new sights of a previously unexplored icy world. For the last couple of days I've been making up for lost time, completely buried in the Dawn Ceres images, and I have some maps and 3D anaglyphs to share with you.

It has been a difficult wait for new New Horizons images, but the wait is almost over; Alan Stern announced at today's Outer Planets Advisory Group meeting that image downlink will resume September 5. In the meantime, a few space fans are making the most of the small amount of data that has been returned to date.

A terrific new visualization tool for comet 67/P Churyumov-Gerasimenko demonstrates the value of sharing mission image data with the public. The browser-based tool lets you spin a simulated 3D view of the comet. It began with a 3D model of the comet created not by ESA, but by a space enthusiast, Mattias Malmer.
