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.

2015 will be the Year of the Dwarf Planet, and you need to tell people about it!

Emily Lakdawalla • March 05, 2014 • 11

I am very excited about 2015, more so than I have been about any year since I started working at The Planetary Society. Dawn will enter orbit at Ceres, and New Horizons, which will fly past Pluto and Charon. But if we want this kind of exploration to continue, I'm challenging you, dear readers, to tell the world why such non-planetary worlds are compelling places to go exploring.

Dawn Journal: Distant interplanetary adventurer

Marc Rayman • August 30, 2013 • 1

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.

Dawn Journal: Craving Power

Marc Rayman • July 30, 2013 • 5

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

Bill Dunford • July 29, 2013 • 4

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

Dawn Journal: Breaking Velocity Records

Marc Rayman • July 02, 2013 • 7

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.

Planetary Radio: Don't Step in That Puddle!

Mat Kaplan • July 01, 2013

Dawn Journal: Thrusting to a new personal best

Marc Rayman • June 02, 2013 • 2

Traveling from one alien world to another, Dawn is reliably powering its way through the main asteroid belt with its ion propulsion system. Vesta falls farther and farther behind as the spacecraft gently and patiently reshapes its orbit around the sun, aiming for a 2015 rendezvous with dwarf planet Ceres.

Dawn Journal: A low-orbit shortcut to Ceres

Marc Rayman • May 02, 2013

Marc Rayman's latest Dawn Journal explains why Dawn is currently closer to the Sun than both Ceres and Vesta.

Dawn Journal: Staying warm en route to Ceres

Marc Rayman • March 30, 2013 • 4

Marc Rayman's latest Dawn journal explains the temperature adjustments engineers make to save power and keep the spacecraft warm.
