On June 3, Hayabusa2 ended use of its ion engines, for now, and is coasting the remaining distance toward Ryugu. It's using an optical navigation camera to image the asteroid's position against a field of background stars to help it navigate.

One of the Cassini mission's goals was to figure out how long a day on Saturn is. We still don't know. A new paper reports a measurement of the rotation period of Saturn that is different from past measurements.

China's fourth lunar mission, Chang’e 4, is expected to begin on May 21 with the launch of a Long March 4C rocket from the Xichang Satellite Launch Centre in the southwest of China. The launch will carry a spacecraft named Queqiao, which will serve as a communication relay satellite between Earth and the lunar farside.

Readers, colleagues, friends: it's finally happened. My first book is finally out in the world. Here's an excerpt that explains the design and operation of Curiosity's MMRTG, (it also applies to the future Mars 2020 rover power supply).

The Juno spacecraft that is currently orbiting Jupiter has obtained the first good images of Jupiter's polar regions. I am presenting here a combined global map of Jupiter, made from a Cassini map I made for the equatorial and temperate regions and polar maps made from the Juno JunoCam and JIRAM polar images.
