Back in 1979 the twin Voyager 1 and 2 spacecraft flew by Jupiter. Some of their images were processed into color images and mosaics that have appeared countless times in books, magazines, on TV and on the Internet. Many of these images and mosaics are spectacular but they were processed more than 30 years ago using computers that are extremely primitive by today's standards. It's possible to get better results by processing the original, raw images from the Voyagers using modern computers and software.
Tens of thousands of Jupiter images were taken by the Voyager spacecraft, but relatively few have been processed to reveal their true beauty and wonder. The latest Snapshots video from Emily Lakdawalla explains why.

In this week's Snapshots from Space video, I talk about the Voyager 1 images of Jupiter -- how many there are (tens of thousands), and what a challenge they represent for image processors. But, I promise, the effort is worth it. Here's just one example: it's a color, crescent view of Jupiter, taken by Voyager 1 as it departed.
On February 24, 2007, the Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long route to a 2014 rendezvous with comet Churyumov-Gerasimenko. At the time, they released two photos from the main science camera, OSIRIS.

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.

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.

Remember that neat picture and movie of Phobos passing by Jupiter that I posted last week? Several people asked me where Jupiter's moons were, and I just assumed that they weren't visible. I was wrong; Mars Express spotted Jupiter's moons along with the planet and Mars' moon!

Late last year I posted an amazing video of Jupiter's moving clouds, an animation made from images that Voyager 1 took as it approached. Below is a new and improved version of that animation. The first one was based on 16 Voyager color photos; this one covers a much longer period of time, and includes 58 images.

A while ago I posted all 99 issues of the Voyager Mission Status Bulletins in PDF format, and now I have another cool item to add to that collection: NASA EP-191, "The Voyager Flights to Jupiter and Saturn."

I was astounded to learn this morning that SOHO can not only see Jupiter, it can actually resolve Jupiter's moons (at least its two outer ones) as points of light separate from their planet!

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.

Space probes grant us perspective, the ability to see our place within the vastness of the solar system. But opportunities to see all of the solar system's planets in one observation are rare. In fact, there's only been one opportunity on one mission to see the whole solar system at once, until now.

I've got a new column in the Planetary Society's member magazine, The Planetary Report, called "Snapshots from Space," highlighting really cool amateur-processed images. I'm excited to have the opportunity to help these people get their work published!
