Haley was Doctor Lewis Zimmerman's holographic personal assistant on Jupiter Station. She was brought on-line in 2367. Haley was the closest thing to a friend Dr. Zimmerman had. Some time prior to 2376, Zimmerman was attending an important symposium on Vulcan when Haley's holographic matrix began to fail. Zimmerman canceled his lecture and returned immediately to Jupiter Station to repair it. When Zimmerman was convinced that he would die of the virus, he dictated in his will a request that Haley's program be allowed to run for as long as Jupiter Station remained in service.
