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. 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...

3. 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 ...

4. 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.

5. 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.

6. 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 ...

7. 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.

8. Rosetta update from mission control

(Web Page; Tue Jan 21 14:06:00 CST 2014)

This article originally appeared on ESA's Rosetta Blog and is reposted here with permission. We spoke with (a slightly tired but hugely happy) Rosetta Spacecraft Operations Manager Andrea Accomazzo earlier this afternoon and he reports ...

9. Rosetta update: Both "big burns" completed successfully

(Web Page; Tue Jun 10 13:04:00 CDT 2014)

Rosetta is now in the final phase of its approach to comet 67P/Churyumov-Gerasimenko after a decade-long journey. Usually, when you steer a spacecraft to a planet, you can use the planet's gravity to help capture you into orbit. But a co...

Description: Rosetta is now in the final phase of its approach to comet 67P/Churyumov-Gerasimenko after a decade-long journey. The two largest burns have now succeeded, and Rosetta reported this morning via Twitter that the second burn was close to perfect.

10. One of my favorite space images of all time: Rosetta was here

(Web Page; Thu Jan 31 17:01:00 CST 2013)

A conversation on Twitter today reminded me of this photo, which is one of my all-time favorite space images: the view from Rosetta during its Mars flyby. I was astonished to discover that it hadn't made the transition to our redesigned ...
