... making its closest approach to the earth later today (at 20:57 UTC, 13th November). The Rosetta spacecraft is on its way to meet, orbit, and land on a comet; this earth pass is a gravity assist manoeuvre to modify its orbit (it beats using a lot of fuel and money).
But you'd be lucky to learn any of this from a casual glance at the project's website. As for me: if I were running the world's second-ranked planetary science programme, I would be making sure that the websites for my missions were better than those of the competition. PR matters. I am not asking for mere empty slickness: Lord knows there is enough of that already. But do none of these people have primary- or high-school-age children who they want to enthuse about the solar system?
UPDATE: And right on cue, they do post a news item: Rosetta Second Earth Swing-by, on the bottom left of the page. I suppose it's better late than never. Actually I am being a little unfair as there is an ESA page on Rosetta, separate to the project home page, where there seems to have been a suitably public fuss for a while. So watching the project's own homepage appears to be a bad way of finding out what's going on, unless one wants to read every fine detail ...
For those interested in the misidentification of Rosetta as a previously unknown asteroid, about to make a close pass of he earth: see the comments below.
