When Rosetta approached comet Churyumov-Gerasimenko last summer, both its shape and its activity were surprising. It looked like two comets welded together at a skinny neck. A new paper explains how the neck may be steepening itself.

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.

Opportunity drove farther into Marathon Valley in August, dug into what appears to be a water-altered rock, and took a lot of picture postcards in what is turning out to be a distinctively different site from any that the mission has found since the robot field geologist landed in 2004.

The New Horizons mission has formally selected its next target after Pluto: a tiny, dim, frozen world currently named 2014 MU69. The spacecraft will perform a series of four rocket firings in October and November to angle its trajectory to pass close by 2014 MU69 in early January 2019. In so doing, New Horizons will become the first flyby craft to pass by a target that was not discovered before the spacecraft launched.

The assembly of the OSIRIS-REx spacecraft continues, with many elements integrated onto the spacecraft ahead of schedule. Last month both OTES and OVIRS were delivered to Lockheed Martin and installed on the science deck.

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.
