Propulsion method missing from entry in 221 a.t. See bold. My suggestion is below.
195 - The laser-propelled, unmanned robot probe, the Giordano Bruno, is launched towards Tau Ceti.
221 - Launch of von neumann probes to the Centauri system.
The von neumann probes would have been laser propelled too. That is my suggestion unless someone has a better one.
