It was initially done entirely by machines; smart machines, machines that were every bit the observer and evaluator, but those machines proved lacking in several ways. They had never been living beings, born and raised in organic environments, feeling what organic sentient beings feel, understanding in non-academic ways what organic sentient beings really wanted or needed. They could only send back samples and reports; they could never send back impressions that others might understand and interpret. They could quantify, but they could not dream.

Sentient beings like the human Ishmael Hand, however, also had their limits, not just physical but mental and emotional as well, and they didn’t live long enough for some of these distances, nor did they have the precision and detail that cybernetic equipment could bring to a job. The marriage of creature and machine was, after much trial and error, found to be the perfect vehicle.

Within, of course, limits.

For if they were not a little bit mad when they left, they certainly were after decades of roaming the vastness of the universe, yet their machine sides were precise and detailed. As time went on, it often became difficult to interpret all the data properly…

Once an uncharted system was sighted, scouted, and thoroughly investigated, the procedure was simple. The ships themselves were almost organic; they could take in debris, dust, rock, whatever was out there and convert it to what they needed, just as their external scoops turned some of it into the interstellar fuels that ran them. From this material they grew small probes according to designs within their complex memory banks, and sent them everywhere in the system. Every type of analysis was performed, every part of everything evaluated. The most dead of worlds could contain something of great or unique value.
