Last of the FATties

With about 4500 km separating Rosetta from comet 67P/C-G, the spacecraft will conduct the last of four FAT – ‘Far Approach Trajectory’ – orbit correction manoeuvres later today.

Once upon a time…

...there was a spacecraft called Rosetta. Rosetta had been travelling in space for 10 years, towards a comet called 67P/Churyumov-Gerasimenko. Before long, Rosetta was able to see the comet in the distance, and she took stunning pictures...

Call for media: Rosetta’s comet rendezvous

From today's ESA press release announcing the media event for Rosetta's arrival at comet 67P/Churyumov-Gerasimenko on 6 August. The event will also be streamed live; details below: The media are invited to join ESA’s science and mission...

The dual personality of comet 67P/C-G

This week’s images of comet 67P/Churyumov-Gerasimenko reveal an extraordinarily irregular shape. We had hints of that in last week’s images and in the unscheduled previews that were seen a few days ago, and in that short time...

Access to Rosetta data

After yesterday's unscheduled release of images of 67P/C-G, our next release will be tomorrow at 15:00 CEST as planned, containing new images and a movie, coordinated with all partners involved in the Rosetta mission. In the meantime,...

The third ‘fat’ burn

  We’re heading for the final 10,000 km between Rosetta and comet 67P/C-G today, with four of ten rendezvous burns left to complete before arriving on 6 August. Tomorrow’s burn is the third of four so-called ‘Far...

The three faces of Rosetta’s comet

What a difference a week can make. Even in the six days since the last image, the shape of comet 67P/Churyumov-Gerasimenko is becoming much more apparent, although still heavily pixelated. This sequence of three images are separated...

Half way through the burns!

Five down, five to go! We’re now half way through the rendezvous burn manoeuvres needed to put Rosetta on course with comet 67P/Churyumov-Gerasimenko, and tomorrow will check off the sixth. Tomorrow’s burn is also the second of...

The comet takes shape, one pixel at a time!

Rosetta’s scientific imaging system OSIRIS is slowly but surely resolving comet 67P/Churyumov-Gerasimenko in its narrow angle camera (NAC), giving the first tantalising hints of its shape. The comet covers about four pixels in this image, which was...

COPS pressure variation during a spacecraft slew, 12 hours after a manoeuvre. The big peak is due to the evaporation of water from the spacecraft when the Sun is shining on its bottom side, producing an acceleration of a few micrometers per s^2, which results in a total delta-V over several hours of a few mm/s.

Rosetta smells its exhaust

Just in time to coincide with today’s orbit correction manoeuvre, we have a great blog update contributed by Kathrin Altwegg, from the ROSINA science team at the University of Bern. A spacecraft is made out of terrestrial...

The Naming of Comets

by ESA science writer Claudia Mignone Let's admit it now. It took us a while but we finally all succeeded and memorised the name of Rosetta's comet: 67P/Churyumov-Gerasimenko. 67P/C-G will work too, especially if you're in a...

Comet 67P/C-G in Rosetta’s navigation camera

Regular readers of this blog will have seen the recent images of comet 67P/Churyumov-Gerasimenko taken with Rosetta’s scientific camera OSIRIS as the comet and Rosetta head towards their early August rendezvous. In today’s entry, Rosetta Mission Manager...
