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.

After a journey of more than a decade, Rosetta has finally arrived at comet 67P Churyumov-Gerasimenko. Confirmation of the successful rocket firing came at about 9:30 UTC via a webcast from ESA's Operations Centre in Darmstadt, Germany.

Beaming scientists all around, spectacular images on large TV screens, and the best - or at least most exciting - yet to come: such was the extraordinary scene at the European Space Operations Centre in Darmstadt, Germany, today as the European Space Agency's Rosetta spacecraft reached its cometary destination.

In less than a day, Rosetta will officially arrive, becoming the first spacecraft ever to orbit a comet! Watch an ESA Livestream of the arrival, and check out the latest photos.

A shift in position has brought shadows into view from Rosetta, outlining scarps and ridges on Churyumov-Gerasimenko.

Rosetta's view of the comet is getting better and better. Today they released a new image from the high-resolution OSIRIS camera, and it's a very fresh one, taken only two days ago. Distinct features are coming into view. And it's finally detailed enough for me to compare it to the five other comets we've visited in the past.

A journey of nearly a decade is almost over. Rosetta is making its final approach to comet 67P/Churyumov-Gerasimenko, and the comet's strange shape is beginning to come into focus. As of today, the spacecraft is only 2000 kilometers away from the comet, and 8 days away from arrival.

Venera 9 and 10 landed on Venus in 1975 and sent back the first images of the planet's surface. Now, Ted Stryk brings new life to these images to show us what it would be like to stand on the Venusian surface.

For the last four weeks, the name of the game for Curiosity has been driving. But these weeks of driving have been more challenging than they used to be.

A single day's observations take us from orbital overviews all the way down to ground truth.

A European space enthusiast, children's author, and volunteer astronomy outreach worker asks for more images from Rosetta.

I could not wait to post these amazing new images of comet Churymov-Gerasimenko from Rosetta. The nucleus of the comet is clearly a contact binary -- two smaller (and unequally sized object) in close contact.

In 1979, the Voyager 1 probe took a stunning series of images on its final approach to Jupiter. Thirty-five years later, almost to the day, a group of seven Swedish amateur astronomers set out to replicate this odyssey, but with images taken with their own ground-based telescopes.
