I know it’s been all Curiosity, all the time on this blog for the last couple of weeks, and that’s not likely to change much for the next couple of weeks. But I don’t want people to forget that there’s another rover exploring Mars’ ancient geology. Opportunity has been taking spectacular photos of Whim Creek and Endeavour Crater this last week.
A measurement of the Andromeda galaxy's proper motion shows it's coming directly at us, and will collide with the Milky Way in 4 billion years. The event will transform the appearance of our night sky.
Cassini obtained its first high-resolution images of Methone on May 20, 2012. Methone is one of the smallest regular moons of Saturn, having a diameter of only about 3 kilometers. It was the first moon that Cassini discovered, very early in Cassini's mission at Saturn, in 2004.

Image magician Daniel Machacek has done it again, producing a jaw-dropping view of Mars from Viking Orbiter 1, featuring a frosty Argyre basin and stretching across to a series of faults called Thaumasia Fossae.
Here's a neat video posted by SungrazerComets (the Twitter identity of the U.S. Naval Research Laboratory's Sungrazing Comets website) this morning. It's an animation of images taken by the Solar and Heliospheric Observatory (SOHO) on May 13 and 14, when Jupiter was passing through solar conjunction
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.

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.

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.

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.

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.

It is always thrilling to see relics of human exploration out there on other worlds. Today, the Lunar Reconnaissance Orbiter Camera team posted some new photos of two defunct spacecraft: the Luna 17 lander and the Lunokhod 1 rover. I've posted images of the two craft before, but the ones released today are much better.
