In Honor of JUICE, a New View of Europa
To celebrate ESA's selection of the JUICE mission to Jupiter, Ted Stryk produced a new global view of Europa from Galileo data.
Pretty pictures from Cassini's 1 May 2012 Dione flyby
Cassini performed its last of three close encounters with Enceladus for 2012 two days ago, and followed the flyby with some spectacular images of Dione.
3D view of an unnamed lunar crater
Grab your red-blue 3D glasses and dive in to this small but spectacular unnamed lunar crater as seen in a Lunar Reconnaissance Orbiter photo.
Dawn Journal: Rising from a happily long LAMO
Marc Rayman's monthly check-in with the Dawn mission describes the achievements of the spacecraft in its Low-Altitude Mapping Orbit (including near-global high-resolution imaging!) and explains what's next.
Mars Exploration Rovers Update: Opportunity Begins to Wrap Winter Science, Mission Celebrates Month 100
As winter began to retreat in the southern hemisphere of the Red Planet, Opportunity was commanded to finish up her science assignments in April in preparation for leaving its refuge, and the Mars Exploration Rover mission rolled through its 100th month of exploration.
Titan, Dead or Alive? A Debate
A lively discussion and debate between planetary polymaths Ralph Lorenz and Jeffrey Moore about Titan, hosted by the Denver Museum of Nature and Science, moderated by David Grinspoon.
Swirly lava patterns in beautiful HiRISE images
In a channel near a pedestal crater on the plains of Cerberus Palus, Mars, there are wacky swirl patterns.
Cartoon: Voyager's ongoing adventures
I'm not sure what to make of this YouTube cartoon about Voyager, except to say that it's simultaneously heart-wrenching, funny, and adorable.
Ski Helene?
I enthused about these Helene images the first time they came down from Cassini, and then forgot about them, and then was thrilled anew a couple of weeks ago when Daniel Macháček posted his version, processed from data published by the Cassini imaging team on April 1.
Cheat sheets for Vesta's craters and Dawn's Vesta timeline
I made myself a cheat sheet to many of Vesta's distinctive-looking craters, and also wrote down a list of the major dates in the timeline of Dawn's exploration of Vesta.
Pioneer Anomaly Solved!
With the latest piece of the puzzle just published in a scientific journal, a solar system mystery that has perplexed people for more than 20 years has been solved, truly thanks to the support of Planetary Society members.
Pretty pictures from Cassini's weekend flybys of Enceladus and Tethys
Cassini flew past both Enceladus and Tethys on April 14. Here's a cool animation of its approach to Enceladus' plumes, and a pretty global picture of Tethys.
Pretty Pictures: Amazing Asteroid Lutetia
A long-awaited data set is finally public (well, long-awaited by me, at least). The Rosetta team has now published their data from the July 10, 2010 flyby of asteroid (21) Lutetia. This data set is absolutely stunning, and my friends in the amateur image processing community wasted no time in creating art out of it.
Nearly the last view of Endeavour with its life-blood flowing
After 12 years of photographing the space shuttle, and even getting to work for NASA as a photographer for the final three years of the program, I never had the privilege of going inside the cockpit until the program was over.
A possible nine-planet system
Someone on Twitter pointed me to a paper recently posted to ArXiv titled
Pretty picture: Janus and Saturn
In the last few days as it's rounded periapsis in its current orbit of Saturn, Cassini has taken a lot of great photos of Saturn's moons. One series of photos was taken from pretty close to Janus, a moon about a third the diameter of Enceladus that orbits between the F and G rings. And among those, several were taken with the moon sitting in front of Saturn.
An update on Opportunity, and a plea for some volunteer desktop publishing help
A. J. S. Rayl has just posted her monthly update on the goings-on at Meridiani planum, noting that the update recaps the 99th month of the Mars Exploration Rover mission. There's a lot of detail on how the radio-tracking campaign is going. While she's not driving, Opportunity's acting like a lander, with radio antennas on Earth performing Doppler tracking to allow very fine measurement of Mars' orbital motion.
Mars Exploration Rovers Update: Opportunity Gets Energy Boost and Works Through Depths of Winter
March came in like a lion and went out like a lamb at Meridiani Planum, Mars: Opportunity felt the cold wind on her solar panels, then
Dawn Journal: Saluting the Sun
On April 18, Dawn will attain its greatest separation yet from Earth, nearly 520 million kilometers. Well beyond Mars, fewer than a dozen spacecraft have ever operated so far from Earth.
Hey amateurs! ESA's running an image processing contest: "Hubble's Hidden Treasures!"
Here's a newly announced contest that is right up my alley and, I hope, of interest to regular readers of this blog. ESA has just announced
