In 1979, the Voyager 1 probe took a stunning series of images on its final approach to Jupiter. Thirty-five years later, almost to the day, a group of seven Swedish amateur astronomers set out to replicate this odyssey, but with images taken with their own ground-based telescopes.

As Cassini celebrates 10 years at Saturn, we're beginning to see its long-term observations of Saturnian moons bear fruit. A surprising new result: While Prometheus exerts control over the F ring and Atlas, Pandora -- long thought to be a shepherd of the F ring -- does not.

Opportunity got off to a bumpy start in June, but the Mars Exploration Rover (MER) mission pressed on, continuing the exploration of Murray Ridge at the western rim of Endeavour Crater.

The latest series of LightSail boom deployment tests went smoothly, paving the way for a full system test later in July.

Opportunity has left the winter haven and is still driving south along the rim of Endeavour crater, currently exploring an outcrop a few meters from crater rim.

Despite its rejection by the NRC Committee, we argue that the Asteroid Redirect Mission (ARM) is an affordable and logical first step in such a sequence. ARM is not only consistent with the NRC Committee’s own principles, but is also the only near- term initiative that can shape their recommendations into a sustainable human space exploration program. ARM would launch U.S. explorers into deep space beyond the Moon, and fits logically into an exploration program aimed at Mars.

We hope you can be with us as we make a major announcement about our solar sail spacecraft, LightSail 1.

On Monday JPL put out a press release marking one year since Curiosity landed -- one Mars year, that is! There was a new version of the Kimberley self-portrait, and a video update on wheel wear testing. While we've been celebrating on Earth, Curiosity has been driving, driving, driving, on a new

The two spacecraft currently orbiting the two innermost planets are both flying low in their orbits in the final phases of their missions. MESSENGER just performed a rocket burn to raise its orbit slightly, while Venus Express did the opposite.

I am both elated and relieved that Rob Manning and William Simon have written Mars Rover Curiosity: An Inside Account from Curiosity's Chief Engineer. The book delivers on the promise of its title, in a slender volume that is full of great stories you'll read nowhere else.

Are we alone in the universe? This month’s National Geographic cover story takes a look at the question, and I weighed in on the subject.

NASA has selected a Planetary Society proposal to study accommodation of the Society’s LIFE (Living Interplanetary Flight Experiment) biomodule on NASA’s Asteroid Redirect Mission (ARM).

For the second day in a row, the Senate failed to vote on a bill that would fund NASA and other agencies in 2015. Without passage, no progress can be made addressing the flaws contained within.
