From the official Tabula Rasa site :

Richard Garriott's flight to the International Space Station began at 2:00 a.m. CST October 12, 2008 with the launch of the Russian Soyuz TMA-13 from the Baikonur Cosmodrome in Kazakhstan.

A couple of minutes after lift-off Richard could be seen on camera holding a message for the fans of Tabula Rasa. It is written in the fictional language of "logos," which figures prominently in the game's storyline. We will not spoil things by revealing the meaning of the message just yet, but we can tell you that it is a quote attributable to someone else.

To see video of the launch, go to the Official Tabula Rasa Channel on YouTube. Because it could not be seen clearly over the camera in the cockpit, here is the message:

Garriott and the crew successfully docked at the space station this morning!

UPDATE: According to this announcement, player Valeshar correctly translated the message as a quote by Konstantin Tsiolkovsky, father of space travel: "The Earth is the cradle of humanity, but mankind cannot stay in the cradle forever."
