NASA selected 21 Participating Scientists to join the Dawn team in 2010, prior to Dawn's arrival at Vesta in 2011. Since that time, Dawn Participating Scientists have made enormous contributions to the mission, as they do for most other NASA missions. But the status of a Participating Scientist program for Dawn at Ceres has been in doubt.
Less than a year from its rendezvous with dwarf planet Ceres, Dawn is continuing to make excellent progress on its ambitious interplanetary adventure. But once it gets to Ceres, just how will it go into orbit? Marc Rayman explains.
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.

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.
Continuing its daring mission to explore some of the last uncharted worlds in the inner solar system, Dawn remains on course and on schedule for its rendezvous with dwarf planet Ceres next year.
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.
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.
Gliding smoothly through the main asteroid belt between Mars and Jupiter, Dawn continues to make good progress on its ambitious mission of exploration. It is patiently but persistently pursuing Ceres, the second destination on its interplanetary itinerary.
Deep in the main asteroid belt between Mars and Jupiter, Dawn is continuing its smooth, silent flight toward dwarf planet Ceres. Far behind it now is the giant protoplanet Vesta, which the spacecraft transformed from a tiny splotch in the night sky to an exotic and richly detailed world.
On the sixth anniversary of leaving Earth to embark on a daring deep-space expedition, Dawn is very, very far from its erstwhile planetary residence. Now humankind's only permanent resident of the main asteroid belt between Mars and Jupiter, the seasoned explorer is making good progress toward the largest object in that part of the solar system, the mysterious dwarf planet Ceres.
