Like the Flower Arranging Aspiration mod, the UFO Investigator Aspiration mod was the brainchild of another creator, R3m, and was then updated by Itsmysimmod and Ilkavelle. This stellar mod is categorized under Knowledge aspirations. It would require your sims to climb up the ranks in the Rocket Science skill, collect plenty of prints, rocks, and alien species, and even travel to the exotic world of Sixam! There are four milestones for this aspiration, which consist of the Stargazer, Conspiracy Theorist, Contactee, and UFO Investigator.
