A guest blogger here recently rounded up the large number of participatory research projects that are collectively known as citizen science. I think these are all very cool and I encourage you to check them out but none of them has yet inspired me to spend my precious time as grunt labor on a gigantic collective project. Until now.

Space.com has taken advantage of the infinitely scrollable nature of Web pages to produce a really cool infographic on the scales of orbital distances in the solar system.

Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

Wednesday morning included some interesting conversations. Notably, I spoke with Pamela Gay, who is responsible for the MoonZoo citizen science program and who is presently working on developing a site through which the public will be able to help search for potential Kuiper belt objects for the New Horizons mission to encounter after the Pluto flyby.

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).

This week is the end for Kodachrome film. It's a casualty of the digital revolution.

Coincidentally, two new images of Neptune were posted today, from two very different sources.

Three years after New Horizons flew past Jupiter on its way to Pluto, the spacecraft has imaged the giant planet again.

Three months ago, grandiosely, I announced that I was going to survey volcanism across the solar system, and I began the journey on Earth. Then I failed to follow up.

The New Horizons science team is meeting this week. Ted Stryk was invited to attend the meeting, and he sent the following notes from the first day.

Last week, planetary astronomers Anne Verbiscer, Michael Skrutskie, and Doug Hamilton published a paper in Nature succinctly titled

Despite still being more than six years and just over 18 Astronomical Units from the Pluto system, the project team for New Horizons is conducting the second and final portion of our Pluto Encounter Preliminary Design Review (EPDR) tomorrow and the next day.

It's time to check in on what's going on with our trusty robots around the solar system.

I thought it would be fun to start the week by taking stock of what's going on with all the active planetary missions out there.

As New Horizons continues its journey (it's now approaching the orbital distance of Saturn, though it's very far from that planet in space), the mission is taking advantage of the recent experience with the Jupiter flyby to plan out the science operations for the Pluto-Charon encounter.

This afternoon Alan Stern posted to unmannedspaceflight.com that New Horizons has successfully completed the trajectory correction maneuver that lines the spacecraft up for its July 14, 2015 encounter with Pluto.

According to the mission website, the New Horizons spacecraft has drifted off to sleep, entering its
