1. Quick Rosetta update: Churyumov-Gerasimenko is a contact binary!

(Web Page; Tue Jul 15 09:20:00 CDT 2014)

I'm just back from vacation and struggling to catch up but 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 s...

Description: 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.

2. New Rosetta view of the comet - and a comparison to other comets

(Web Page; Mon Aug 04 09:54:00 CDT 2014)

Rosetta's view of Churyumov-Gerasimenko 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. I'm...

Description: 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.

3. Rosetta is awake!

(Web Page; Mon Jan 20 14:49:00 CST 2014)

It was a tense half an hour for Rosetta fans all over the world as we waited for a spike in a graph to inform us that Rosetta had awoken from a 31-month slumber to phone home. But the spike -- indicating that a giant radio dish had detec...

4. [UPDATED] New Rosetta images show comet's craggy shape

(Web Page; Sat Aug 02 11:10:00 CDT 2014)

A new NavCam view of Rosetta's target comet, released this morning, gives us comet fans a new perspective on its craggy shape. UPDATE: And just an hour after I posted this NavCam image, they released an OSIRIS image, too. In both images,...

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

5. Rosetta's Big Day

(Web Page; Wed Aug 06 17:45:00 CDT 2014)

The following originally appeared on Stuart Atkinson's blog and is reposted here with permission. A hundred years ago today, Europe was preparing to fling itself into the most brutal war ever known. There were – as far as I know &...

Description: Stuart Atkinson muses on the difference between the Europe of today and the Europe of a century ago in the context of Rosetta's momentous arrival at comet Churyumov-Gerasimenko.

6. 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 ...

7. 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.

8. 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.

9. 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 ...

10. Rosetta update: Instrument commissioning going well; Philae cameras activated

(Web Page; Tue Apr 22 12:49:00 CDT 2014)

Rosetta and Philae have very nearly completed a six-week phase of spacecraft and instrument checkouts to prepare the mission to do science. Recently, the lander used its cameras for the first time since hibernation, producing some new ...
