The International Conference on Environmental Systems, or ICES (known prior to 1990 as the Intersociety Conference on Environmental Systems), is an annual technical conference focusing on human spaceflight technology and space human factors. Session topics include: Environmental Control and Life Support Systems (ECLSS), thermal control, life sciences, extra-vehicular activity (EVA) systems (including space suit design and human-robot interaction), space architecture, and mission planning for exploration. The conference has taken place annually since 1971.
