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.

Europa may get a mission...eventually. We give our first take on the 2015 NASA Budget request. How does Planetary Exploration fare? Which projects were cancelled? Will NASA capture an asteroid? And most importantly, what can you do about it?

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.

Would you like to be part of one of the largest citizen-science efforts in the history of astronomy? The International Occultation Timing Association (IOTA) invites you to join in the campaign to observe and time the best and brightest asteroid occultation ever predicted to occur over a populated area – and no telescope is required!

Animated maps of the planets show the spheres in motion.

Imagine flying deep within the asteroid belt to study the most unreachable location in the solar system: the deep core of a terrestrial world.

NEOWISE has reawakened to discover many more asteroids and comets. The mission leader thanks the amateur astronomers who follow up on these discoveries.

2013 is drawing to a close, providing a nice opportunity to reflect on the outgoing year and look back at some of the highlights that we have experienced. Here are my top-20 OSIRIS-REx moments of this past year.

The International Astronomical Union has chosen the names Aegis and Gorgoneion for the two moons of the asteroid (93) Minerva. We decided to crowd-source the names, catching the attention of the public. Over the following year, I received a lot of emails with suggestions

There is a paper in press at Icarus by Xiaoduan Zou and five coauthors that provides the first peer-reviewed publication I've seen on the results of the imaging experiment performed during the Chang'e 2 flyby of near-Earth asteroid (4179) Toutatis.

This week, the United Nations will move one step closer to an international response to the threat from near Earth objects (NEOs).

The Space Generation Advisory Council (SGAC) has just announced a new asteroid naming competition, open to anyone, so if you've ever wanted to name an asteroid, now's your chance.

The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

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.

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.

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

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.
