What is Mission Analysis for the First-Ever Saturn Trojan 2019 UO$_{14}$ about?

In mid-2024, asteroid 2019 UO$_{14}$ was identified as the first-ever Saturn Trojan through ground-based archival observations and numerical simulations. Trojans, including those associated with Jupiter and other planets, raise important questions about the formation processes of our solar system. Exploring this Trojan object with spacecraft may provide direct answers and definitive evidence regarding these questions. This paper thoroughly investigates potential mission scenarios to the first Saturn Trojan, 2019 UO$_{14}$, to determine the necessary launch window and spacecraft specifications. First, by assuming a ballistic flight using chemical engines, optimal sequences of events, including (powered) gravity-assist maneuvers and deep-space maneuvers, are identified through a meta-heuristic global trajectory optimization algorithm. The analysis indicates that flyby exploration is feasible with a launch window around 2034 and a $\Delta V$ ranging from 92 m/s to 1041 m/s within an 11-year mission duration, while a rendezvous can be achieved with a departure around 2035 and a $\Delta V$ of 2-3 km/s. Specifically, the itinerary via Saturn requires a $\Delta V$ of 2 km/s and a flight t
