Voyager

Forty years ago, NASA launched two robotic explorers on a mission to travel farther than any craft had gone before, and today, they continue to be our most distant emissaries.

Voyager project scientist Ed Stone discusses the greatest achievements of the epic mission, which lifted off 40 years ago today (Aug. 20).

Nearly 40 years after lifting off, NASA's historic Voyager mission is still exploring the cosmos.

The crowdfunding project has smashed through its Kickstarter goal — but remastering the famous NASA capsule from Earth was no easy task.

Thirty-five years ago today, NASA's Voyager 2 spacecraft got an up-close look at beautiful, enigmatic Saturn.

NASA's life-hunting Viking mission to Mars was the most complex robotic exploration effort of its day, but the space agency initially wanted it to be even more ambitious.

On Jan. 24, 1986, NASA's robotic Voyager 2 probe zoomed by Uranus, giving humanity its first up-close look at the seventh planet from the sun.
