How did the Voyager spacecraft manage to weave their magnificent way through the outer planets of our solar system? Mission Design Manager Charley Kohlhase led the team that crunched the numbers to select the best possible trajectory from 10,000 candidates. The results have been astounding. Emily Lakdawalla prepares us for the arrival of Europe’s Exomars orbiter and Schiaparelli lander. Bill Nye says millennials and President Obama share excitement about humans to Mars.

High-resolution global view of Jupiter from Voyager 1
A 14-frame mosaic of Jupiter from Voyager 1. Most of the data for this mosaic was captured in a 3-by-3 mosaic at around 8:45 on February 27, 1979, but gaps were filled with data taken an hour before and an hour later.

Saturn and its rings from Voyager 1
Voyager 1 looked back at Saturn on Nov. 16, 1980, four days after the spacecraft flew past the planet, to observe the appearance of Saturn and its rings from this unique perspective. A few of the spokelike ring features discovered by Voyager appear in the rings as bright patches in this image, taken at a distance of 5.3 million kilometers (3.3 million miles) from the planet. Saturn's shadow falls upon the rings, and the bright Saturn crescent is seen through all but the densest portion of the rings.

Uranus' crescent, February 1, 1986
A week after its flyby, Voyager 2 still had a high-resolution view of Uranus' receding crescent using its narrow-angle camera.

Neptune in natural color from Voyager 2
This Voyager 2 Narrow Angle Camera image of Neptune was taken on August 20, 1989 as the spacecraft approached the planet for a flyby on August 25. The Great Dark Spot, flanked by cirrus clouds, is at center. A smaller dark storm, Dark Spot Jr., is rotating into view at bottom left. Additionally, a patch of white cirrus clouds to its north, named "Scooter" for its rapid motion relative to other features, is visible. This image was constructed using orange, green and synthetic violet (50/50 blend of green filter and UV filter images) taken between 626 and 643 UT.

The Pale Blue Dot of Earth
This image of Earth is one of 60 frames taken by the Voyager 1 spacecraft on February 14, 1990 from a distance of more than 6 billion kilometers (4 billion miles) and about 32 degrees above the ecliptic plane. In the image the Earth is a mere point of light, a crescent only 0.12 pixel in size. Our planet was caught in the center of one of the scattered light rays resulting from taking the image so close to the Sun. This image is part of Voyager 1's final photographic assignment which captured family portraits of the Sun and planets.
