ESA Release: "We sent the command via NASA's 70 m Deep Space Network station in Canberra, Australia, ensuring the signal was transmitted with enough power to reach Rosetta, which is now 549 million km from Earth"
It has been a hive of activity here for the past week. ESA wanted to have some people on the ground here in Canberra to ensure that everything went well. We did our usual magnificent job of course and, as confirmed by their media release, the ESA team were very happy with how it all turned out. Sleep well Rosetta, the alarm is set for 2014

I had yet to see any scientific result of the 2007 Mars flyby, so this paper is quite welcome: Rosetta-Alice Observations of Exospheric Hydrogen and Oxygen on Mars
-------------------- I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

Most of the Rosetta cruise phase data up to the Steins flyby are now archived, see

Looks like the content mirrors that of the PDS Small Bodies Node archive. Too bad the VIRTIS dataset wasn't released. Earth (Mars as well?) high spectral resolution visual spectra = yummy.

an interesting paper recently published in Astronomy & Astrophysics:
The nucleus of Comet 67P/Churyumov-Gerasimenko - A new shape model and thermophysical analysis (in free access after registration) if the authors are right, the nucleus of C-G should look more like a flattened spheroid than like a starfish as assumed until now. they predict that it may resemble a rounded body like Tempel 1. -------------------- I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

From my point of view this is a much more realistic shape model. The oddly symmetrical star-shap of the previous model screamed 'artifact' at me.
