The biggest news on Curiosity of late is that the rover has drilled her fourth full drill hole on Mars! Drilling happened at a site called

ESA announced today that Philae will be landing on November 12, 2014. What time the landing occurs depends on which landing site they use. If they go to the prime landing site,

This morning, the European Space Agency announced the selection of a landing site for little Philae on the head of comet Churyumov-Gerasimenko. Although a primary site has been selected, landing Philae successfully is going to be tough, and the mission is now working to manage people's expectations.

At the European Planetary Science Congress held this week in Portugal, the Rosetta team showcased some early science results from Rosetta's mission to comet Churyumov-Gerasimenko.

ESA released another set of NavCam images of the comet today, and lo and behold, there are jets! We knew they were there, from an earlier OSIRIS image, but it's tremendously cool to see the comet behaving like a proper comet should.

After a pause of about a week in daily image releases from Rosetta, ESA has begun sharing four-image sets of photos of comet Churyumov-Gerasimenko and invited the public to help produce pretty pictures from them.

The Rosetta team has announced the selection of five regions on Churyumov-Gerasimenko that they will study as possible landing sites for little Philae. Now, as Rosetta surveys the comet from its second triangular

In honor of the 25th anniversary of the Voyager 2 flyby of Neptune, image magician Björn Jónsson has produced two new global mosaics of the distant ice giant, the highest-resolution ever made.

Shooting video of a lumpy moon crossing the Sun and turning it into a giant googly eye is not a new activity for Curiosity, but I get a fresh thrill each time I see one of these sequences downlinked from the rover.

Rosetta spent the week transitioning to a lower orbit from which it continues to observe the comet. This weekend, the mission will select about five landing sites for more detailed study. They have also now estimated the mass of the comet.

The Mars gremlins really had it in for Curiosity this month. A computer glitch and slippery sand conspired to delay the rover's progress toward Mount Sharp. And shifting rocks proved unsafe for drilling. The rover will continue driving toward Mount Sharp, departing Bonanza King without drilling, skirting Hidden Valley along a plateau to its north.

Rosetta has nearly completed its first funky three-cornered orbit in front of the comet. Each day we're getting views of the nucleus from more directions. I step you through Churyumov-Gerasimenko's geography.

What's that in the distance? A binary star? Those are two little round worlds dancing in circles, whirling around a point in space located between the two of them. It's Pluto and Charon, clearly separated by New Horizons' camera.
