A happy ending to this story: JPL reported yesterday evening that the flipped bit in Voyager 2's flight data system software has been successfully toggled back to its correct value.

Voyager 2's engineers have confirmed that the problem with the spacecraft was indeed the result of a single flipped bit in its software, as they predicted.

Good old Voyager 2; she takes a licking and keeps on ticking.

Engineers have shifted NASA's Voyager 2 spacecraft into a mode that transmits only spacecraft health and status data while they diagnose an unexpected change in the pattern of returning data.

Here's how to watch the class on how to access Voyager data through the Planetary Data System, which I conducted to a small audience this morning.

Here's a lovely amateur-produced color image of Jupiter's moon Callisto, or, as its artist Daniel Macháček calls it,

For some reason both Jason Perry and Ted Stryk took it upon themselves to produce new, pretty versions of Jupiter's moon Europa this week, so I'm hereby featuring them!

On Sunday comes the twentieth anniversary of an iconic image from the Voyager mission: the

Did you think I was going to skip Uranus? How could I?

Here's yet another of the moons of Uranus for you: Ariel, a near-twin in diameter to Umbriel, but apparently with more interesting geology.

Miranda is the one moon of Uranus for which we have very good images from Voyager 2, and that was a stroke of luck, because low-resolution shots of all of Uranus' moons would have told us that it was, geologically speaking, the most dramatic of the five biggest ones.

Here's Neptune, but not quite like you've ever seen it before.

Proteus is a weird name for this world. It's the second-largest moon of Neptune, and so it's named (as are all of Neptune's moons) for deities associated with the sea.

Jupiter has been high overhead at sunset for several months, a brilliant light that's easy to spot even when the sky is still bright at dusk; but it's now moving quickly to the west as Earth speeds ahead of Jupiter's more stately march around the Sun.

Umbriel is the darkest moon in a pretty dark place in the solar system, the Uranus system.

Here is every single image of the last two moons discovered prior to the Voyager 2 encounter, Titania and Umbriel.

I got an urge to dive in to the Voyager image archives and see what exactly we have here on Earth to base our understanding of the Uranian moons on.

Saturn is surrounded by a crowded family of rings and moons, and two of those moons -- Epimetheus and Janus -- orbit Saturn so close together that it seems as though their different orbital speeds should make them crash into each other.

Linda Morabito Kelly began working at Jet Propulsion Laboratories while still a student at the University of Southern California. In 1974, she accepted a fulltime position as an engineer in the Satellite Ephemeris Development and Orbit Determination section JPL.
