Yesterday Cassini passed unusually close by Hyperion, the oddly shaped moon that orbits Saturn just beyond Titan. Among the many cool images captured during this flyby were three that I used to make this neato view of Hyperion's crescent.

A pair of lunar spacecraft is launching in two weeks, and NASA had their preview press briefing this morning. Notable from that briefing was this spiffy video.

NASA funds regular meetings of scientists who work on different parts of the solar system to provide scientific input into NASA's future plans. These

I haven't checked in on Cassini lately. I went to the raw images page and found the frames for this very lovely, very close view of Saturn. It was taken by Cassini two days ago, as it was approaching periapsis.

365 Days of Astronomy is a daily podcast that is almost entirely user-driven. Each podcast, which can cover astronomical, cosmological, planetological, or educational topics, is written, recorded, and submitted by people like you who are excited about space.

Last Friday I posted an awesome video of Martian clouds in motion. This week I'll tell you how I made it. The how-to is split up into two parts. The first, today, is how to access Mars Express HRSC image data and process it into the individual animation frames, from which you can make an animated GIF.

In spite of some bad weather conditions during the first part of this year, the new camera bought with funds from a Planetary Society Shoemaker Near Earth Object grant helped us to discover and confirm ten new near-Earth objects.

We are super excited that the Planetary Society’s Phobos LIFE (Living Interplanetary Flight Experiment) is about ready to launch to Mars’ moon Phobos and back. We have been working for years preparing this unique test of the effects of long term exposure to deep space on a wide variety of life.

Behold an amazing (if I do say so myself) video of Martian clouds in motion.

This is a bit of a departure from space science, but was so awesome, I had to share. I've always loved Tom Lehrer's

It's the first time I've ever seen anything like this -- two identical spacecraft, side by side on one launch adapter ring.

Dawn's images of Vesta show craters upon craters, but the longer I study the images, the wackier the craters look.

While doing my daily reading today I was struck by the awesomeness of two recent blog posts. Both were composed not by professional bloggers like me but by professional space explorers, one a scientist and the other an engineer.

This photo is making the rounds of Twitter, Facebook, Google+, and whatever other social network you care to name today. It was shot by astronaut Ron Garan from the Space Station, and it's a meteor seen from above. Way cool.

Amateur astronomer Patrick Wiggins sent me this neat little animation of comet Garradd moving against background stars through an hour's worth of observing. I'm not any kind of astronomer but if I were I think I would get a kick out of looking at things that appear to move within one night of watching -- asteroids, comets, Jupiter's spots. I'm impatient that way.

I was not trained as a journalist, so before I started working for the Planetary Society I had no understanding of how much news reporters depend upon press releases to generate story ideas. Did you know that most of the news that you read on the Web or in a newspaper or hear on the radio probably originated as a press release or an arranged press event from somewhere?
