The Vesaya was a Vulcan starship, a science vessel that saw service in the mid-21st century.

In the year 2063, this ship was commanded by Captain Sevak and detected the presence of a warp signature emanating from the planet Earth. Records from the Vulcan Science Academy indicated that Humanity had entered a planetary conflict and was suspected to have destroyed themselves. However, the detection of the warp ship led to the Vesaya investigating the planet believing that if Humans had survived, they were in no condition to harm Vulcan.

This chain of events led to First contact occuring between the survivors of Earth and the Confederacy of Vulcan. (Last Unicorn RPG module: The Way of Kolinahr: The Vulcans)

The Decipher RPG module: Starships indicated that it was the T'Plana-Hath that discovered Earth but it is possible that the ship was simply a survey craft that was attached to the Vesaya.
