A nice mission would be to lead an expedition in the future with other guardians towards Jupiter and its moons (to find out about the nine). We would get near the area then some sort of space storm or enemy missile would hit us and throw us off course, and we'd fall uncontrollably towards Jupiter's giant red eye. As we approach the eye its destructive storm would destroy half our ship and we'd start violently spinning out of control right into it. Next we'd wake up stranded in a remote location, and as we look up standing in front of us is Xur. Idk this might not make sense lore-wise or scientifically but it'd make a hella cutscene.
