Voyager 2 is now outside the reach of the solar wind, traveling in the interstellar medium. Unlike Voyager 1, Voyager 2 has a working plasma spectrometer so will be doing exciting new science. It is expected to last another 5 to 10 years, though not with all instruments operating.

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.

Today is the 40th anniversary of the launch of Voyager 1. Four decades later, both spacecraft survive, still producing science, still working on their interstellar missions. On the occasion of the anniversary, we revisit Carl Sagan's reflections on the significance of the Voyager missions.

Björn Jónsson argues that even now, 40 years after Voyager 1 and 2 were launched, a lot of the data they returned is still of high interest.

In 1979, both Voyager missions captured thousands of photos of Jupiter as frames of movies of the giant planet spinning among its moons. In honor of the mission's 40th launch anniversary, Ian Regan has reprocessed the data to produce stunning new movies.
