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.

The House of Representatives proposed $2.1 billion for NASA's planetary science budget, which would be an all-time high. Part of the increase would be used to start work on a new reconnaissance and communications orbiter.
