Observations of Interstellar Objects (ISOs) passing through the solar system allow for the direct examination of planetesimals from other star systems. The passage of the third known interstellar object (ISO), 3I/ATLAS, through the solar system has produced the largest set of spacecraft observations for any comet or ISO to date, with observations were obtained from a total of 24 spacecraft to date, including interplanetary spacecraft, a number of solar probes, and 6 astronomical space telescopes. This session invites presentations on science results from terrestrial and spacecraft observations of all three known ISOs, on how the lessons learned from their observation can be applied to future interstellar targets of opportunity, and on plans for future ISO interceptor missions.
