We received many hundreds of emails during this week. We cannot respond individually to all your mails, but we would like to thank all those who sent messages of congratulations to ESA and its international partners NASA and ASI. We also received constructive criticism in order to spur us to do even better next time around. Your good suggestions will be taken into account.

We received a number of exciting interpretations of images from professional and amateur astronomers worldwide, and these have been passed on to the Science teams.

Cassini-Huygens is a truly international adventure, and this partnership is reflected on the web. Material on all the highlights of this joint mission is published in parallel by ESA and NASA.

A big thank you to all our visitors from all over the world – we hope that you keep visiting the ESA Portal to learn more about Titan as the scientific teams continue to analyse the data, and to find out more about the Agency’s other activities.
