The Dawn mission is executing an ambitious bonus goal recently devised for its extended mission. Mission Manager and Chief Engineer Marc Rayman brings us his monthly update.

Dawn Journal: Looking Back, Looking Forward

Dawn is concluding a remarkable year of exploring dwarf planet Ceres. Chief Engineer and Mission Manager Marc Rayman brings us his latest update.

LPSC 2016: Differentiated meteorites provide a glimpse of the early solar system and planets

This year's Lunar and Planetary Science Conference included a session devoted to a group of rocks from space called differentiated meteorites, and their proposed parent bodies.

Dawn Journal: Descent to LAMO

Dawn's Chief Engineer and Mission Director Marc Rayman previews what's in store as the spacecraft moves into its final mapping orbit around dwarf planet Ceres.

DPS 2015: Solar System Formation

At the 47th Division of Planetary Systems meeting, many presentations touched on some of the most contentious and poorly known aspects of how planets form.

Dawn Journal: 8 Years in Space

On the 8th anniversary of the launch of the Dawn spacecraft, Chief Engineer and Mission Director Marc Rayman gives his annual summary of Dawn’s progress on its interplanetary travels.

What did Dawn learn at Vesta?

It's now been two years since Dawn wrapped up its work at the second-largest asteroid. What else did we get from the Vesta encounter besides great photos? Recently, I asked Dawn's deputy project scientist, Carol Raymond, for help in summarizing a few of the big things Dawn taught us.

Pretty pictures: Vesta's dark material

More masterful processing of Dawn Vesta images by Björn Jónsson, including Aelia crater and some mysterious dark splats near Fulvia crater.

Dark mountain on Vesta: Aricia Tholus

Newly processed images of one of the more puzzling features on the surface of Vesta: a dark mountain named Aricia Tholus.

LPSC 2014: Water on...Vesta?

At the Lunar and Planetary Science Conference, Jennifer Scully discussed possible water-carved gullies in an unusual location: within craters on Vesta. Water-carved gullies on Mars I can accept; but on an airless lumpy body? I was intrigued.

Pretty Picture: Three Wanderers

With all the excitement happening on missions criscrossing the solar system, I often forget to enjoy the views of our solar system that we can achieve from home. Amateur astronomers don't make the same mistake. Here's a lovely photo that Stuart Atkinson sent me, captured last night from Kendal, England, showing four special wanderers.

Mission Leader Bruce Jakosky's MAVEN Prepares for Mars

Pay attention! This Mars orbiter, headed for launch in November, is a terrific science mission, as Mat Kaplan learned in a recent workshop, and in this week's Planetary Radio.

Two new ways to browse Vesta: 2. Vesta Image data browser

A few weeks ago I received an email pointing me to a really cool new map-based browser to Dawn's Vesta image data.

Two new ways to browse Vesta: 1. Vesta Low-Altitude Mapping Orbit (LAMO) Atlas

Last week was the European Planetary Science Congress in London, and there's been a lot of science news. One thing that caught my eye Friday was the publication of a new atlas for Vesta.

Dawn Journal: Distant interplanetary adventurer

Traveling confidently and alone, Dawn continues to make its way through the silent depths of the main asteroid belt. The interplanetary adventurer is on its long journey to the uncharted dwarf planet Ceres, by far the largest of all asteroids.

Producing global views of Vesta from archival data

Björn Jónsson produces beautiful color and 3D global mosaics of Vesta from Dawn's archival data.

Dawn Journal: Craving Power

Ion propulsion is not a source of power for Dawn. Rather, the craft needs a great deal of power to operate its ion propulsion system and all other systems. It needs so much that...we crave power!!

Terra Cognita

Pushing back the frontier, and filling in the blank spaces on the map.

Dawn Journal: Breaking Velocity Records

The indefatigable Dawn spacecraft is continuing its extraordinary interplanetary flight on behalf of inquisitive creatures on distant Earth. Progressing ever farther from Vesta, the rocky and rugged world it so recently explored, the ship is making good progress toward its second port of call, dwarf planet Ceres.
