A generation ship travels to a star system that has at least one planet that's believed to be potentially habitable and, therefore, a possible location for a colony. After sending some probes that return encouraging data, a manned spacecraft is launched from the generation ship to do a short (2-3 day) recon survey of the planet to scout for potential colonization locations. The recon craft has a crew of four.
What roles and technical/scientific abilities would you want the crew members to have?
The assumption here is that each crew member would have more than one area of expertise. For example, the pilot might also be a mechanical engineer, while another might be an exobiologist and some other kind of scientist. I'd assume that one would be a medical officer in addition to one or more other roles. Would one have computer/IT abilities as one of their roles? Would there be a second member who also could serve as pilot in case of something happening to the main pilot? Would one have hydrology as one of their specializations? How many types of engineers would the crew need to encompass? Would one of them (all of them?) need to be armed and combat trained?
So please state what you think would be the most useful and likely division of labor between the crew members.
