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. More jets from Rosetta's comet!

(Web Page; Sat Sep 20 11:00:00 CDT 2014)

Here's a lovely new view of Rosetta's comet, taken on September 19 (yes, today!). I have a new technique for processing Rosetta pictures to get the most out of the jets -- I'll explain below. First, enjoy this glorious new photo! I parti...

Description: Another lovely view of comet Churyumov-Gerasimenko contains jets. Bonus: Emily explains how to use a flat field to rid these glorious Rosetta NavCam images of faint stripes and specks.

3. New Rosetta views and first science on comet Churyumov-Gerasimenko from EPSC

(Web Page; Mon Sep 15 10:35:00 CDT 2014)

Just weeks after their arrival at comet Churyumov-Gerasimenko, the Rosetta science team showcased their first results at the European Planetary Science Congress. The session included results from most of the science teams, but arguably t...

Description: 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.

4. 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.

5. Rosetta is awake!

(Web Page; Tue May 29 06:55:00 CDT 2018)

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...

6. Rosetta is gone

(Web Page; Mon May 22 18:07:00 CDT 2017)

Today there is one less spacecraft returning science data from beyond Earth. The European Space Operations Centre received the final transmission from Rosetta at 11:19 September 30, UT. A very quiet control center and press room watched ...

7. Citizen scientist spots changes on Rosetta's comet

(Web Page; Fri Apr 07 15:47:00 CDT 2017)

Back in 2015, as Rosetta’s comet, 67P, was approaching perihelion, scientists noticed the surface changing before their eyes. These “very significant alterations,” according to the European Space Agency, were located in...

Description: Citizen scientist and self-described "comet whisperer" Marco Parisi explains how he made a striking discovery on Comet 67P using Rosetta mission data.

8. [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.

9. Rosetta spacecraft may be dying, but Rosetta science will go on

(Web Page; Thu Sep 29 12:47:00 CDT 2016)

The Rosetta mission will end tomorrow when the spacecraft impacts the comet. ESA took advantage of the presence of hundreds of members of the media to put on a showcase of Rosetta science. If there’s one thing I learned today from ...

Description: The Rosetta mission will end tomorrow when the spacecraft impacts the comet. ESA took advantage of the presence of hundreds of members of the media to put on a showcase of Rosetta science. If there’s one thing I learned today from all the science presentations, it’s this: Rosetta data will be informing scientific work for decades to come.

10. 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.
