Blast from the past: Pioneer 10 and 11 pictures of Jupiter
Posted by Emily Lakdawalla on 2011/09/07 02:06 CDT
Here's a few pretty pictures that were recently dusted off by Ted Stryk. Pioneer 10 and 11 passed by Jupiter on December 4, 1973, and December 3, 1974, respectively. Here are three pictures from those two encounters, in versions newly processed by Ted from scanned photographic prints found during a research trip to NASA's Ames Research Center.

Opportunity's wheels are on a whole new different kind of rock: she has arrived at the rim of Endeavour crater, on Cape York.
Pretty picture: five moons for Cassini

Explaining how to combine the red, green and blue images from a recent Cassini image session containing five of Saturn's moons: Janus, Pandora, Enceladus, Mimas and Rhea.
Cassini animations: Rhea and Dione and Titan

I've been mucking about in the Cassini data archives (as I often do when procrastinating) and unearthed a neat, if short, mutual event sequence of two crescent moons passing by each other.

Cassini finally catches Helene

Some recent photos that Cassini took from a position nearly in Saturn's shadow caught my eye, and I made a quick color composite. What an amazing view this would be if you were riding on the spacecraft!
Lots of great stuff in the latest Cassini data release

I've got some lovely pictures from Saturn to show you! Every three months, the Cassini mission dumps gigabytes worth of precious Saturn data into the Planetary Data System, and the latest gift came on April 1. This particular pile of data, which was taken between April 1 and June 30, 2010, contains a lot of really terrific moon observations.

The photo I took of Curiosity's "face" and posted on Monday seems to have tickled a lot of people. I understand it's the subject of a "Photoshop this Mars rover" challenge at Fark, and a couple of the guys over at unmannedspaceflight.com have been having a field day with it.
LPSC 2011: Wanted: Pioneer 10 & 11 digital data
Posted by Emily Lakdawalla on 2011/03/11 01:39 CST
This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.
Pretty picture: Viking 1 across Mars
Posted by Emily Lakdawalla on 2011/03/09 10:10 CST
Image magician Daniel Macháček has been turning his energies to Viking Orbiter views of Mars lately, with some stunning results, like the one below. I'm not sure how he makes images that look so sharp and clean and with such rich color out of the Viking Orbiter data.

To relieve this week's text-heavy LPSC posts, here's a brief one on an incredible panorama across Saturn's northern storm, taken on February 26 by Cassini and assembled by unmannedspaceflight.com member "Astro0."
Some recent pictures of Saturn's northern storm
Posted by Emily Lakdawalla on 2011/02/07 04:35 CST
There is a huge storm that's spreading across so much of Saturn that it's been readily visible even from Earth-based telescopes. Over the past couple of days a couple of new images of Saturn have appeared that show just how enormous the storm is today.

Here's an image I've been meaning to post for months, a new mosaic from Voyager 1 by Ted Stryk of Io crossing Jupiter's terminator as it neared closest approach.

In the past week there have been 25th anniversaries of two events in 1986, one great, one terrible: the closest approach of Voyager 2 to Uranus on January 24, and the explosion of the space shuttle Challenger upon liftoff on January 28.

I've spent the day noodling around in the current issue of Icarus, following up some of the more interesting stories within its table of contents, and came across a picture of this very cool crater -- actually, set of craters -- on Mars.
Animation of Phobos rotating from recent Mars Express flyby images
Posted by Emily Lakdawalla on 2011/01/25 10:18 CST
Daniel Macháček has colorized some terrific images of Phobos and run them through some morphing software to make a seamless animation that appears to show Phobos rotating before you.
Two fine color Cassini animations: Prometheus rotating, Tethys and Dione dancing
Posted by Emily Lakdawalla on 2011/01/20 11:23 CST
Daniel Macháček has reached into the dark side of Prometheus and pulled out an incredible amount of detail where the potato-shaped moon is illuminated by Saturnshine. He produced an animation that morphs among the three sets of four-filter color images that Cassini snapped during the flyby.

Thanks to its active volcanic activity and sulfur-rich surface, Io is one of the most colorful worlds yet seen in the Solar System, save the Earth of course
Titan and Dione: The same, but different
Posted by Emily Lakdawalla on 2010/04/22 05:29 CDT
Here's a new lovely color composition of Titan and Dione captured by Cassini. This one was taken on April 20, 2010; a set of 15 raw images taken of the two moons just showed up on the Cassini raw images website.
