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.

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

Comet ISON is brightening as it approaches the Sun, and can now be seen from many ground-based telescopes.

Recently, almost a thousand researchers gathered in London for Europe’s annual meeting of planetary scientists. Here's a report from one session on cometary science.

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.

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

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.

Just four months ago I posted about a paper recently published by Leslie Young and coauthors that described three possible scenarios for Pluto's atmosphere. Yesterday, Cathy Olkin, Leslie Young, and coauthors posted a preprint on arXiv that says that only one of those scenarios can be true. And it's a surprising one. The title of their paper says it all:

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.

Alan Stern

New Horizons has just completed a summer of intensive activities and entered hibernation on Aug. 20. The routine parts of the activities included thorough checkouts of all our backup systems (result: they work fine!) and of all our scientific instruments (they work fine too!).

Using a Shoemaker NEO Grant a new telescope is operating in Illinois to do asteroid tracking.

In which the fifth graders of Kipp Heartwood Academy argue the competing sides in the is-Pluto-a-planet debate through the medium of rap.

For several weeks now, ground-based observers have been blind to Comet ISON as our local star was sitting directly between us and the comet. I am delighted to share two pieces of good news: first, that ISON is still alive and well, and secondly that it has been recovered.

Daniel Fischer

Space blogger Daniel Fischer provides a preview of the exciting interplanetary observing campaign that has recently begun to study comet C/2012 S1 (ISON) from vantage points across the solar system.

Shoemaker NEO Grant winner Bob Stephens specializes in lightcurves of near Earth asteroids to determine their physical properties. Here is an update on recent progress using his 2013 Planetary Society grant. This is the first in a series of updates on Shoemaker NEO Grant winners.
