ISS FARS D014 Page 4 Thursday, July 5, 2001 4:18 PM The ISS sensors are connected by cables to the Sensor Interface Module (SIM), located inside the radiation shield. The SIM contains electronics which measure and store weather values for transmission to the console via cable or radio waves. The radiation shield’s white plastic plates protect the SIM from sun and other sources of radiated and reflected heat, and from precipitation.

ISS FARS D014 Page 9 Thursday, July 5, 2001 4:18 PM Fan-Aspirated ISS Options Low-Current Fan Unit The optional low-current fan unit uses less power than the standard fan. This allows the solar-powered Fan-Aspirated ISS to run for a longer period of time during low-light conditions. It is recommended for use in extreme latitudes during the Winter months, in climates that experience extended periods of cloudy weather, or for any location with limited solar exposure.
