Rosetta
According to an article published last January 7 on Le Monde, three
alternative flight plans are being studied for Rosetta:
1) Launch in November 2003, to fly by Venus and to orbit Wirtanen. This
would require some modification due to the far lower perhielion distance
2) Launch in April 2004, to fly by Venus and to orbit Wirtanen
3) Launch in February 2004, to orbit Churyumov-Gerasimenko
Actually, there are 5 or 6 different scenarios, but I also read that it won't be launched until next year.
