TransSolar was a Federation-based company active in the late 23rd century. They were engaged in shipping, trade of goods and long-range trade expeditions. One company asset was the Eridani Star, a small commercial transport vessel which it used for long-range exploration for the purposes of trade. For this role they placed one of their most enterprising officers in the captain's position. InstellCo was a rival of TransSolar. Though InstellCo was much smaller, it had no qualms about criminal activities to compete.
