A potential second interstellar object C/2019 Q4 (Borisov) was discovered after the first known interstellar object 1I/’Oumuamua. Can we send a spacecraft to this object, using existing technologies? In this paper, we assess the technical feasibility of a mission to C/2019 Q4 (Borisov), using existing technologies. We apply the Optimum Interplanetary Trajectory Software (OITS) tool to generate trajectories to C/2019 Q4 (Borisov). As results, we get the minimal DeltaV trajectory with a launch date in July 2018. For this trajectory, a Falcon Heavy launcher could have hauled a 2 ton spacecraft to C/2019 Q4 (Borisov). For a later launch date, results for a combined powered Jupiter flyby with a Solar Oberth maneuver are presented. For a launch in 2030, we could reach C/2019 Q4 (Borisov) in 2045, using the Space Launch System, up-scaled Parker probe heatshield technology, and solid propulsion engines. A CubeSat-class spacecraft with a mass of 3 kg could be sent to C/2019 Q4 (Borisov). If C/2019 Q4 (Borisov) turns out to be indeed an interstellar object, its discovery shortly after the discovery of 1I/’Oumuamua implies that the next interstellar object might be discovered in the near future. The feasibility of a mission to both, 1I/’Oumuamua and C/2019 Q4 (Borisov) using existing technologies indicates that missions to further interstellar objects are likely to be feasible as well.
