Some parallels exist between Odysseus' journey and the discoveries of exoplanets. What initially started out as a well-planned trip from Troy back to Ithaca, turned into a series of rather unfortunate events, with episodes of fighting Cyclops and having your crew turned into swine.

It's a fact of life in science that not all of your hypotheses will turn out to be correct (or even verifiable at all). But there's a bias toward the publication of positive results -- the discovery of this, or the proof of that.

I was driving home from the Mars Science Laboratory site selection workshop yesterday when I got a thrilling call informing me that I've been awarded the 2011 Jonathan Eberhart Planetary Sciences Journalism Award.

I've been attending the final Mars Science Laboratory Landing Site Community Workshop meeting this week, taking copious notes for a future article in The Planetary Report, some of which I'll post here when I get a chance. But I just had to write a brief post about the totally crazy role reversal that is going on at this meeting.

According to a story posted on xinmin.xn and run through Google Translate, there's now been an official announcement from China about Chang'e 2's extended mission: it will depart lunar orbit in mid-June and journey to L2.

Late last year I posted an amazing video of Jupiter's moving clouds, an animation made from images that Voyager 1 took as it approached. Below is a new and improved version of that animation. The first one was based on 16 Voyager color photos; this one covers a much longer period of time, and includes 58 images.

A fresh report was published online yesterday in Science Express on the discovery of a magma ocean beneath the surface of Io. Big news! This is a paper I've been looking forward to seeing for more than year and half.

Remember SETI@home? The ground-breaking computing project is now taking a look at candidate Earth-like planets that have been detected by NASA's Kepler space telescope.

Citizen Science projects let volunteers easily contribute to active science programs. They're useful when there is so much data it overwhelms computing algorithms (if they exist) or the scientific research team attempting to process it.

It's hard to convey just how excited I am to see Dawn's first image of asteroid Vesta.

Here's a theoretical paper that asks an interesting question: When the solar system was very young and still very hot, could medium-sized asteroids have been habitable abodes for life?

Meteorites hit Earth all the time, but they almost never score direct hits on human-built structures (or humans, for that matter). Once in a while, though, direct hits do happen, and it looks like this recent event in Poland was the real thing.

I recently read two graphic novels exploring the early history of spaceflight, and I'd like to recommend both for summer reading. Although the two overlap in time, they couldn't be much more different.

I have always found maps of the motions of Earth's continents fascinating, so it is really cool to see some gorgeous new reconstructions of what Earth would have looked like to spaceborne observers over the last 750 million years.

Now that Dawn has finally begun its science mission at Vesta, I thought it'd be useful to go back through Marc Rayman's Dawn Journals to collect a summary of the plans for Vesta.

Dawn is on the threshold of a new world. After more than three and a half years of interplanetary travel covering in excess of 2.6 billion kilometers (1.6 billion miles), we are closing in on our first destination. Dawn is starting its approach to Vesta.

There is a traffic jam of planets on the eastern horizon in the early morning right now and for the next several weeks, a prize for those of you who have to rise before dawn.

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.

As Opportunity drove her little robot heart out, breaking the 28-kilometer mark on her odometer, and driving the longest backward drive ever, April proved to be another month of exhilarating highs for the Mars Exploration Rover mission and one extended low with only silence from Spirit, despite intensified efforts by her Earth crew to establish contact.

The Planetary Society's Shuttle LIFE experiment is now go for launch on Endeavour's STS-134 mission. I came down to Florida for the loading of our tiny sample tubes into the CREST-1 (Commercial Reusable Experiments for Science & Technology) payload block.
