JAXA held a press conference on June 30 about the latest report from the review board that is charged with finding out what exactly caused Akatsuki's failure to enter orbit at Venus, and what that implies for the possibility of Akatsuki to try again when it returns to Venus in 2015 or 2016.

Opportunity 'burned up' the Meridiani Plains in June as it raced toward its much-anticipated next destination and the Mars Exploration Rover (MER) mission cruised into the 90th month of what was originally to have been a 90-day tour.

I've been mucking about in the Cassini data archives (as I often do when procrastinating) and unearthed a neat, if short, mutual event sequence of two crescent moons passing by each other.

Vesta beckons, and Dawn responds. Now more than halfway through its approach to Vesta, Dawn continues creeping up on the destination it has been pursuing since it began its interplanetary travels.

I am pretty sure that the Dawn team put nearly every image they've taken of Vesta so far in the animation they released yesterday, which is awesome. It hasn't taken long for the amateur image processing community to pick that animation apart into its component frames and process the heck out of the individual images to produce some very fine looking images and animations.

There was a press briefing on Dawn today at NASA Headquarters, and there are new pictures! Here's what Vesta looked like as of three days ago, when Dawn was only 189,000 kilometers away.

Nature News is reporting that the Mars Science Laboratory mission has made its recommendation for the landing site for the next great Mars rover, and it's Gale crater.

All right, I'll admit it: JPL's video is way, way cooler than mine. Four days of packing Curiosity up for shipping, condensed into under a minute.

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.

Remember that neat picture and movie of Phobos passing by Jupiter that I posted last week? Several people asked me where Jupiter's moons were, and I just assumed that they weren't visible. I was wrong; Mars Express spotted Jupiter's moons along with the planet and Mars' moon!

Cassini has finally achieved gorgeous global imaging of Helene with a spectacular flyby on Saturday, in which they got Helene to pose prettily for the camera from beginning to end of the encounter. And what a wacky, wacky world Cassini has revealed Helene to be!!

Closer and closer! Vesta is still fuzzy, but as Dawn inexorably draws closer it's beginning to come into focus. The view is now better than anything Hubble has ever returned to Earth.

Here is a really cool view of Phobos in the foreground with gigantic (but very distant) Jupiter sitting in the background, a fortuitous alignment that the Mars Express High-Resolution Stereo Camera team took advantage of on June 1.

It's not easy to wrap a ginormous rover for shipping. I was glued to the feed from the Curiosity Cam all day yesterday, as they prepared Curiosity for shipping to Kennedy Space Center. Here's a low-budget time-lapse of the rover being wrapped.

There was a press briefing today giving some early science results from MESSENGER and it was surprisingly meaty. I'm going to focus on just one set of the results that they presented.

According to an article published a week ago by the Xinhua news service, Chang'E 2 departed the Moon on June 9 at 09:10 UTC. It's now headed toward a Lagrangian point in space, but not the one I thought it was headed for.

There is something about the Spirit Mars rover, something that tugs at our hearts. I finally figured it out: it's cute.

One big space event that I missed while I was on vacation was Rosetta's entry into hibernation. Rosetta is the biggest interplanetary spacecraft that has been launched by ESA, and it has the groundbreaking goal of entering orbit around a comet and dropping a lander onto it.

What do you know! I spend my last pre-vacation post whining about the lack of image releases from Dawn as it approaches Vesta and what do I find in my Inbox on the morning of my return to work but: an image release from Dawn!

For now, Mars continues to eclipse Jupiter's moon Europa (shown here to scale) in NASA's flagship mission plans, but not in its appeal to many planetary scientists.
