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.

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

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.

A Vesta rotation movie from Dawn!!

Emily Lakdawalla • June 13, 2011

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!

Dawn Journal: Vesta to choose Dawn's arrival time

Marc Rayman • May 30, 2011

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.

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.

Dawn's Vesta phase timeline, a summary

Emily Lakdawalla • May 03, 2011

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.

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.
