 One of the more notable incidents involving Orbit occurred when umpire Gary Darling ejected the mascot from the game for arguing balls and strikes.In addition to his role as the Astros' mascot, Orbit made a one-time appearance as "Marty the Mariner Martian" during a "Turn Ahead the Clock" promotion at a 1998 Seattle Mariners game.Orbit was replaced with Junction Jack beginning in the 2000 season, with the team's move from the Astrodome to then Enron Field.
