Prospector
"Difference between us and the Lonestar schmucks, we don't care if it's bolted down." - Donny Husjak, prospector.
Prospectors are members of the expedition team who report to the foreman, but who's primary mission takes place far away from the station. In general, prospectors are dispatched to investigate areas around the colony and planets. They will typically be required to encounter danger and face extraterrestrial threats in the course of their job.
Setup
Unlike other members of the colony, the prospectors are very likely to require weapons and equipment that rivals security. Care must be taken to avoid this equipment from falling into the hands of untrained personnel. A good prospector will prepare for any possibility be it bad weather, cave ins, or armed hostile humanoids.
Exploring
The prospector's main job function is to explore, locate any devices or artifacts of interest, make contact with any indigenous life, and generally make new discoveries while looting everything that isn't nailed down and even then stealing the nails if they're not secured properly.
You should be familiar with Standard Operating Procedure with regards to away missions, and make sure you follow the directions of the expedition foreman if present.
Weaponry and You
Unlike the rest of the crew, who are not permitted to have rifles/experimental weapons, you are permitted to carry weapons to further your job as necessary, but only to and from the expedition prep area or personal lockers legally, anyway. For legal purposes, you should leave your weapons in the prep room or a private locker when going off-duty.
The marshals are within their rights to charge you with possessing contraband, should you be searched for some other offense while not on duty. If you assault someone in the bar and while being processed security discovers your x-ray laser, you may be charged with possessing major contraband.
