Mars gives up its secrets through the unseen colors of its rocks.
Back in 2005 and 2006, when Pluto’s second and third moons (Nix and Hydra) were discovered, searches by astronomers for still more moons didn’t reveal any. So the accidental discovery of Pluto’s fourth moon by the Hubble Space Telescope in mid-2011 raised the possibility that the hazards in the Pluto system might be greater than previously anticipated.
Next week I'm traveling to speak at two events. Registration is still open for both, so I hope some of you can come. I also have some commentary on women being invited to speak at public events.
A look at an older paper describing Galileo's possible sighting of individual ring particles orbiting Jupiter as companions to its inner moon Amalthea.
Caleph Wilson provides examples and guidance to scientists wishing to mentor students in science, technology, engineering, and math outreach programs.
Two weeks ago I wrote about Kiera Wilmot, a teen girl who was expelled from her school and charged with two felonies for unsupervised messing around with a chemical reaction on school grounds. Yesterday the Orlando Sentinel reported that no charges are being filed against her, which removes the greatest threat to her future.
An exciting new option to enhance NASA's OSIRIS-REx asteroid mission has been proposed by Steve Chesley at JPL. The ISIS spacecraft would impact asteroid Bennu to expose its interior structure to OSIRIS-REx.
I've been out of town for a couple of days and am overwhelmed with work and an overflowing email box. So what do I do about that? I ignore what I'm supposed to be doing and play with Cassini raw image data, of course. Here is a "mutual event" of Mimas (the bigger moon) and Pandora (the outer shepherd of the F ring).
A Soyuz capsule carrying Roman Romanenko, Chris Hadfield and Tom Marshburn landed safely in Kazhakstan after 146 days in space.
Following an ammonia leak reported Thursday morning, NASA is planning a spacewalk to investigate a radiator on the P6 truss.

The Asteroid Emergency Response Tabletop Exercise at the Planetary Defense Conference
Posted by Mat Kaplan on 2013/05/07 05:02 CDT
Planetary Radio for the week of May 6 visits the Planetary Defense Conference one last time to join a "tabletop" simulation of a killer asteroid threat.
Please bear with me -- this blog entry has nothing to do with planets but a lot to do with society. For the last two days, my Twitter feed has been roiling with outrage about the story of Kiera Wilmot.
