Someone asked about what I would use with this, solo, however I think this list would work fine either way.
Depending on system, I would use the Cepheus Engine SRD by Jason Kemp:

and either Mongoose 1e Zhodani:

Broadsword from Classic Traveller:

The 800ton Exploration Frigate in Makara's Sea is a drop in replacement for a Broadsword; and the Zhodani can work as the Sidereals (call the "Science of the Mind" cultists, or something), also that the Strike Cruiser in either book, that is a random event from the table, is included in either supplement. I would probably follow the mission of jump in system with the two scout corps frigates, and roll up a planet randomly, while checking for encounters.
Here is a scout career also:

I think also one could find a map from online, and go exploring, maybe with some sort of random occurrence, though I don't know how well that would work out solo. Encountering ship though, or aliens, like in the original Star Trek, I wouldn't necessarily assume they are hostile, maybe work out a morale roll, or use the reaction table.
