In a story that I've been following for quite a while, Jupiter's southern equatorial belt, having faded to white in 2009, is now well on its way back to its former red glory.

The views from Opportunity of Endeavour's near and distant rim peaks are getting ever more vertical as Opportunity approaches Cape York.

Here's the latest image release from Dawn at Vesta, taken from an altitude about twice as high as that of their first mapping orbit.

In this, my second blog on Origins 2011 in Montpellier, France, a conference dedicated to the interdisciplinary research on the origins of life, I aim to provide my impression of the second half of the conference.

A few weeks ago a producer for a public television space documentary asked me if I knew of any cool Cassini animations and my answer was,

After covering 2.8 billion kilometers (1.7 billion miles) on its own, after traveling for nearly four years through the lonely emptiness of interplanetary space, after being bound by the gravity only of the sun, Dawn is finally in orbit around Vesta.

The news leaked a few weeks ago has turned out to be true: the next Mars rover, Curiosity, will be headed for Gale crater on Mars when it launches at the end of this year.

Maybe it's my own peculiar variant of pareidolia, but every time I see a new image of Vesta I'm reminded of some different other lumpy body in the solar system. In the image released just now by the Dawn team, taken from 10,500 kilometers away, I'm seeing Hyperion.

For miles and miles of Martian terrain, Opportunity's view forward has contained a distinctive line of hills—the far rim of Endeavour crater.

That's right: Hubble observations have yielded the discovery of a third small body orbiting Pluto and Charon.

Yet another sharp-eyed reader (I love my readers!) pointed out to me that the German-language release on the MPS website about the latest Vesta image from Dawn included what looked like a tiny thumbnail of a color view.

A sharp-eyed reader noticed that a size comparison montage posted by the Dawn mission today included an image of Vesta that had not yet been released separately to the public, and it is a very cool one.

There's a new orbital mission on the map! As of Friday, the relatively small mass of the asteroid Vesta has finally taken hold of its new artificial satellite, Dawn.

The Origins 2011 conference, which took place last week in Montpellier, France, was dedicated to the origins of life and its occurrence in the universe. At this meeting, scientists from very different disciplines came together to share their ideas.

Well, after three days of fascinating science and heated discussion, the fifth and final MSL landing site workshop has come to a close, and the consensus is -- that all of the sites are pretty darn interesting.

The Hubble Space Telescope has recorded its millionth observation. The planet is designated HAT-P-7b.

Here's a photo of Vesta that was released by the Dawn team on Friday. I didn't post it right away because the version of the image in the official release has some bizarre processing artifacts that make it look as though the image had been made by cutting construction paper.

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.

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.
