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.
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.
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.
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.
It's just two days now until Rosetta arrives in its initial 100-kilometer "orbit" of comet Churyumov-Gerasimenko, and the latest view from Rosetta's NavCam is fascinating. Circular features on the comet remind me of Tempel 1 as seen by Deep Impact and Stardust.
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.
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.
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.
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.
