What a great piece of news to receive upon returning home from vacation! There is now a small piece of the solar system named for me: asteroid 274860 has been formally named

Talking to spacecraft is a normal occurrence at Arecibo Observatory, but sometimes the nuts and bolts are a little unconventional.

I could not wait to post these amazing new images of comet Churymov-Gerasimenko from Rosetta. The nucleus of the comet is clearly a contact binary -- two smaller (and unequally sized object) in close contact.

High resolution images from the Lunar Reconnaissance Orbiter Camera detail the 1973 path of the Soviet rover Lunokhod 2.

I’m excited to report some big news on The Planetary Society’s LightSail project: actual launch dates on actual launch vehicles!

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.

A team of Colombian researchers are arguing for a new refinement to the idea of the habitable zone that takes the presence of life itself into account.

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.

A new animation of 67P/Churyumov-Gerasimenko captured by the Rosetta spacecraft shows the comet rotating.

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.

Award-winning astrophotographer Adam Block showcases some of his stunning images of what happens when galaxies get a little too close to each other.

Dawn's chief engineer and mission director Marc Rayman gives an overview of the plan for the penultimate orbital phase at Ceres, the “high altitude mapping orbit” (HAMO).

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
