Emily Lakdawalla • March 21, 2014 • 3

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

Emily Lakdawalla • March 12, 2014

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.

Dawn Journal: Maneuvering Around Ceres

Dawn Journal: Onward to Ceres

Marc Rayman • February 01, 2014 • 4

The majority of Dawn's time in the Ceres approach phase will be devoted to continuing ion-powered flight. Let’s take another look at how this remarkable technology is used to deliver the adventurer to the desired orbit around Ceres.

Dawn Journal: Planning for the Ceres Approach Phase

Marc Rayman • January 01, 2014 • 4

Now more than halfway through its journey from protoplanet Vesta to dwarf planet Ceres, Dawn is continuing to use its advanced ion propulsion system to reshape its orbit around the sun. Now that the ship is closer to the uncharted shores ahead than the lands it unveiled astern, we will begin looking at the plans for exploring another alien world.

With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
