S1-Truss. Dimensions: 13.7 meters x 4.6 meters x 1.8 meters (45 feet x 15 feet x 6 feet)[;] Weight: 14,124 kilograms (31,137 pounds). The S1 Truss, the first starboard truss segment, was attached to the starboard side of the S0 Truss Oct. 10, 2002. The S1 Truss provides structural support for the Active Thermal Control System, Mobile Transporter and one Crew and Equipment Translation Aid cart. The cart is manually operated by a spacewalker and can also be used as a work platform. The cooling system is like the one in a car radiator except that it uses 99.9 percent pure ammonia, compared to 1 percent in household products. The Thermal Radiator Rotary Joint rotates the three radiator structures in a 105-degree span either way to keep the three radiators panels in the shade; it also transfers power and ammonia to the radiators. The S1 Truss also has mounts for cameras and lights, as well as antenna support equipment for S-band communications equipment.
