Vesta's wacky craters

Emily Lakdawalla • August 16, 2011

Dawn's images of Vesta show craters upon craters, but the longer I study the images, the wackier the craters look.

What I see in the first high-res Dawn images of Vesta

Emily Lakdawalla • August 02, 2011

I had to wait until the kids were in bed and the husband fed last night before I finally had time to sit down and really look at the Dawn images of Vesta. And I still hardly knew where to begin. This brand new world is just so different than others I've seen.

Fabulous Dawn Vesta images and rotation movie!!

Emily Lakdawalla • August 01, 2011

Now that Dawn's close enough to Vesta, we're seeing absolutely spectacular detail and tremendous diversity across Vesta's surface. As usual it'll probably take me a while to bring together all the new information, so as a stopgap I'm going to post an awesome image and a rotation movie.

A different face of Vesta (oh, *there's* the craters!)

Emily Lakdawalla • July 29, 2011

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.

Dawn Journal: Dawn has arrived!

Marc Rayman • July 26, 2011

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.

Vesta in infrared color!

Emily Lakdawalla • July 19, 2011

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.

Yet another new image of Vesta

Emily Lakdawalla • July 18, 2011

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.

Congratulations to the Dawn team on their orbit entry & pretty pictures!

Emily Lakdawalla • July 18, 2011

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.

Origins 2011 conference, part 1

Frank Trixler • July 14, 2011

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.

Ever closer to Vesta

Emily Lakdawalla • July 04, 2011

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.

Amateur takes on the Dawn Vesta images

Emily Lakdawalla • June 24, 2011

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.

Vesta looks pretty battered

Emily Lakdawalla • June 23, 2011

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.

Vesta, now better than Hubble!

Emily Lakdawalla • June 17, 2011

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.

Land ho!

Emily Lakdawalla • May 11, 2011

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

Why haven't we found evidence for life starting in asteroids?

Emily Lakdawalla • May 10, 2011

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?

The scale of our solar system

Emily Lakdawalla • May 02, 2011

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.

Place names on Lutetia

Emily Lakdawalla • April 26, 2011

Whenever we explore someplace new -- a new island, a new continent, a new cave, a new world -- there's a necessary activity that explorers must perform before they can sensibly tell the world about their discoveries: name things.

So far, no moons found at Ceres or Vesta

Emily Lakdawalla • April 15, 2011

Since the Galileo mission discovered tiny Dactyl circling Ida in 1993, quite a lot of asteroid systems have been found to be binary; there are even a few triples. So it's quite reasonable to guess that two of the biggest asteroids, Ceres and Vesta, might also have satellites.

Welcome to Carnival of Space #191

Welcome, everyone, to the Planetary Society Blog for the 191st Carnival of Space! Every week, a different webmaster or blogger hosts the Carnival, showcasing articles written on the topic of space.

In honor of Stardust: The Annefrank encounter

Emily Lakdawalla • March 24, 2011

Since Stardust is being decommissioned today I thought it'd be fitting to take a look back at one of its data sets. I hadn't fiddled with the Annefrank data set before, and it was small and easy to deal with.
