A look back at when the Voyager spacecraft sparked a love affair with an ocean moon.
Space exploration is at its core an optimistic, peaceful and cooperative endeavor. This week we look at some reminders of that spirit of exploration.
NASA’s Voyager missions provided an unprecedented glimpse into the outer solar system.
A look at record-breaking missions, worlds and feats of exploration.
With space missions like JWST and Voyager, decades of development yield decades of discovery.
Looking at planets and moons from near and far, and figuring out how to get all the way out there.
Here are some of our favorite pictures of Saturn's iconic rings, featuring images from Cassini, Voyager 1 and 2 and more.
All the wonders that the cosmos offered up this week, plus news about NASA’s leadership and an exciting launch.
Even Sagan would be amazed by multitudes we now know our cosmos may hold. Learn more, plus get your scoop on the week’s space news.
The leader of the Cassini spacecraft imaging team discusses pale blue dots, life on Enceladus, terraforming Mars, Pluto, Carl Sagan, and more.
Last month marked the 40th anniversary of the historic Voyager 1 encounter with Jupiter in 1979.
The color of Uranus and Neptune is similar, but not identical. Uranus appears greener and Neptune bluer.
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.
Take a look at how electronics of spacecraft are built to survive the harshness of space environments.
To start the week, Voyager 2's best image of Tethys.
Planetary scientist Paul Schenk shares his story of working on the Voyager missions as a JPL intern back in 1979.
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.
