Can we send a spacecraft to this object, using existing technologies? In this paper we assess the technical feasibility of a near-term mission to 2I\/Borisov. We apply the Optimum Interplanetary Trajectory Software (OITS) tool to generate trajectories to 2I\/Borisov. As results, we get the minimal \u0394V trajectory with a launch date in July 2018. For this trajectory, a Falcon Heavy launcher could have hauled an 8 ton spacecraft to 2I\/Borisov. For a later launch date, results for a combined powered Jupiter flyby with a Solar Oberth maneuver are presented. For a launch in 2027, we could reach 2I\/Borisov in 2052, using the Space Launch System (SLS), up-scaled Parker probe heat shield technology, and solid propulsion engines. Using a SLS a spacecraft with a mass of 765 kg could be sent to 2I\/Borisov. A Falcon Heavy could deliver 202 kg to 2I\/Borisov. Arrival times sooner than 2052 can potentially be achieved but with higher \u0394V requirements and lower spacecraft payload masses. 2I\/Borisov&#8217;s discovery shortly after the discovery of 1I\/&#8217;Oumuamua implies that the next interstellar object might be discovered in the near future. The feasibility of a mission to both, 1I\/&#8217;Oumuamua and 2I\/Borisov using existing technologies indicates that missions to at least some future interstellar objects are feasible as well.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Adam Hibberd, Nikolaos Perakis, Andreas M.
