 Washington - Astronauts on board the International on Tuesday prepared Japanese experiments for installation on a porch outside the station.The crew of the space shuttle Endeavour used the craft's robotic arm to remove a carrier of Japanese experiments from the shuttle's cargo area. In a complex robotic ballet, US astronauts Julie Payette and Mark Polansky then manoeuvred the arm for a handoff to the station's robotic arm operated by Japanese astronaut Koichi Wakata and US astronaut Doug Hurley. The arm then placed the package of experiments on the end of the Japanese Kibo module's new porch, where the equipment will be unloaded Thursday. The Endeavour brought the porch to the ISS and it was installed during a spacewalk and robotic effort on Saturday. The four-ton porch on the station's Japanese laboratory will be used to expose scientific experiments to the extremities of space through X- ray cameras and studies of cosmic dust. The experiments unloaded Tuesday were an X-ray camera and a communication system. On Thursday, Wakata and US astronaut Tim Kopra will use a Japanese robotic arm to take the experiments out of their box and install them on the porch. A spacewalk Monday saw astronauts unloading spare parts to the ISS. The next of five total spacewalks for the mission is set for Wednesday, with most of the time devoted to changing batteries on one of ISS's solar panels.(dpa) |
