11. Rosetta update: Final orbit matching phase has begun

(Web Page; Thu May 08 16:14:00 CDT 2014)

Rosetta is in the final stage of its approach to comet 67P Churyumov-Gerasimenko. Yesterday, the spacecraft successfully performed the first of ten burns it needs to match velocity with the comet. The first eight burns are scheduled for ...

Description: Rosetta is in the final stage of its approach to comet 67P Churyumov-Gerasimenko. Yesterday, the spacecraft successfully performed the first of ten burns it needs to match velocity with the comet.

12. Rosetta completes another rocket burn, spies decreasing activity on comet

(Web Page; Thu Jun 19 11:56:00 CDT 2014)

Rosetta has now completed its three largest rendezvous burns as it approaches ever closer to comet 67P/Churyumov-Gerasimenko. Yesterday's slowed it by another 89 meters per second, leaving it with only slightly more than 100 meters per s...

Description: Rosetta has now completed its three largest rendezvous burns as it approaches ever closer to comet 67P/Churyumov-Gerasimenko. Beginning on July 2, Rosetta will now conduct weekly burns, through August 6. Meanwhile, the cometary activity of April and May has quieted again, leaving the comet looking smaller than it did before.

13. Rosetta shifts from sedate circular orbits to swooping flybys

(Web Page; Tue May 29 10:23:00 CDT 2018)

Rosetta's mission to comet Churyumov-Gerasimenko has changed character. For the period of time before and after the Philae landing, Rosetta was able to orbit the comet close enough that it was in gravitationally bound orbits, circling th...

Description: For the period of time before and after the Philae landing, Rosetta was able to orbit the comet close enough that it was in gravitationally bound orbits, circling the comet's center of gravity. As the comet's activity increases, the spacecraft has to spend most of its time farther away, performing occasional close flybys. The first of these is at 6 kilometers, on February 14.

14. More than 2000 Rosetta NavCam images for your enjoyment

(Web Page; Tue Jul 07 14:10:00 CDT 2015)

Last week, the European Space Agency released the first set of images from Rosetta's navigational camera, or NavCam, from the phase of the mission that followed the Philae landing. That makes more than 3500 NavCam images that have been r...

15. Rosetta update: Two close flybys of an increasingly active comet

(Web Page; Tue Apr 21 15:06:00 CDT 2015)

In the two months since I last checked up on the Rosetta mission, the comet has heated up, displaying more and more jet activity. Perihelion is now only four months away, and the pictures are just getting more and more dramatic with time...

Description: In the two months since I last checked up on the Rosetta mission, the comet has heated up, displaying more and more jet activity. Rosetta completed very close flybys on February 14 and March 28, taking amazing photos. But comet dust is making navigation difficult, so the mission is now keeping a respectful distance from the comet and replanning its future path.

16. Rosetta in the Rearview: What Have We Learned?

(Web Page; Tue Nov 15 12:19:00 CST 2016)

Just over a month ago the European Space Agency’s Rosetta spacecraft finished its mission by spectacularly diving into Comet 67P/Churyumov-Gerasimenko, the subject of roughly two years of ground-breaking observations at unprecedent...

Description: Just over a month ago the European Space Agency’s Rosetta spacecraft finished its mission by spectacularly diving into the comet 67P/Churyumov-Gerasimenko. How did it observations influence and alter our ideas about the typical formation and lifetime of a comet?

17. Rosetta’s comet is starting to take shape

(Web Page; Thu Jul 03 12:58:00 CDT 2014)

Emily is on vacation for two weeks, so I’ve been filling in as the blog editor. I promised to cover any breaking news on her usual beats. One of her requests was to watch for new pictures from Rosetta, the European Space Agency spa...

Description: A new animation of 67P/Churyumov-Gerasimenko captured by the Rosetta spacecraft shows the comet rotating.

18. Today's the day Rosetta arrives at a comet!

(Web Page; Tue Aug 05 11:15:00 CDT 2014)

The latest image from comet Churyumov-Gerasimenko was taken from less than 250 kilometers away. In less than a day, Rosetta will officially arrive, becoming the first spacecraft ever to orbit a comet! Here's a lovely composite of all ...

Description: 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.

19. Rosetta end-of-mission event schedule

(Web Page; Thu Sep 29 04:04:00 CDT 2016)

The end is near for Rosetta. As I explained earlier this month, ESA plans to set Rosetta down on the surface of the comet on September 30, with its final signals reaching Earth at 04:20 PDT / 07:20 EDT / 11:20 UTC / 13:20 CEST, give or t...

20. Comet spotted! Rosetta's first sight of Churymov-Gerasimenko since wakeup

(Web Page; Thu Mar 27 09:57:00 CDT 2014)

Rosetta is doing the spacecraft equivalent of yawning and stretching after its long sleep, and last week the spacecraft rubbed its proverbial eyes and blinked a few times, squinting at its distant target. Comet Churyumov-Gerasimenko is s...

Description: Rosetta has turned on its cameras and sighted its comet for the first time since waking from hibernation. Next activity: waking the Philae lander.
