4、video services, and heard very little crew positive reporting.Lesson(s) Learned: The PD knows the crew procedures most intimately. During complex trouble shooting of experiments there is a need for the PD to have direct communications with the trouble shooter/crew and also visual (video) access to t
5、he experiment itself.Recommendation(s): Provide ISS video services to remote sites (e.g., Glenn Research Centers Telescience Support Center), install the communication infrastructure on ISS that makes it convenient for the crew to perform positive reporting, and let the PD, who knows the crew proced
