Dawn remains healthy and on course as it continues to approach Vesta. Thrusting with its ion propulsion system, as it has for most of its interplanetary journey so far, the spacecraft is gradually matching its solar orbit to that of the protoplanet just ahead.

Laser beams and space exploration are perfect for each other, and not just because all self-respecting starship captains know their way around a blaster. It turns out that zapping rocks with a laser is not only fun, it also can tell you what they're made of!

NASA has selected the OSIRIS-REx mission as the next New Frontiers mission. OSIRIS-REx (Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer) will be the first U.S. asteroid sample return.

Yesterday, I remarked that despite the declaration of her death we'll be seeing Spirit frequently over the next few years, as long as Mars Reconnaissance Orbiter is still monitoring her landing site with its HiRISE camera. I said that Spirit is a lump that's relatively easy to spot because of her dark shadow. Well, Spirit's managed to make herself even easier to spot than that.

Alicia Chang reported today that, according to project manager John Callas, the last attempt to uplink a command to the Mars Exploration Rover Spirit will be made tomorrow. NASA will cease listening for signals from Spirit on Tuesday.

It figures. I just start a three-week trip, with my only computer a diminutive Netbook, and guess what's just been radioed across the 1.3 billion kilometers separating us and Saturn? A set of photos that should become -- when properly processed -- an iconic image from Cassini's fourteen-year mission to the Saturn system.

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.

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.

One nice thing about the Planetary Defense conference is that I not only get to talk with the NEO community of experts all in one place and hear their new science, but I also get updates on projects the Planetary Society has funded.
