The UNSS Marco Polo was a Terran Merchant-class trade vessel in the United Nations Solar Fleet of the mid-22nd century. It was commanded by Captain Lorenzo Malfatti. Following information from Tellarite traders, the Marco Polo visited the trading planet of Rigel IV in 2079 SFC (c. 2150), the first Terran ship to do so. As it was unknown what goods could be sold there, its holds contained a wide range of different goods, including substances like oxygen, argon and coal, metals such as boron steel, carbon-epoxy composites, electronic equipment, and Terran clothing and artworks.
