A complex robotics operation involving multiple handoffs between the station and shuttle robotics arms successfully moved Express Logistics Carrier-4 (ELC-4) from space shuttle Discovery’s cargo bay to the Earth-facing side of the station’s right hand truss, or backbone. ELC-4 was attached to its permanent location on the starboard 3 truss Saturday at 10:12 p.m. EST. There it will store spare parts, including a heat rejecting radiator it carried to space for possible future use to cool the station.
Because the work kept the crew members awake later than scheduled, Mission Control advised them they can sleep in 30 minutes late on Sunday, awakening at 7:23 a.m.
