Shuttle astronauts armed and ready
Space shuttle Endeavour's crew have completed the delicate process of attaching a massive robot arm to the international space station.
Canadian astronaut Chris Hadfield and US astronaut Scott Parazynski spent more than seven hours unfolding the arm from the shuttle bay and wiring it up.
"It looks real good," said Hadfield, the first Canadian to walk in space. The astronauts sped through their chores, hooking up power, data and video cables for the new space station arm and then installing a radio antenna on the orbiting laboratory. The 58-foot Canadian-built arm is critical to the continued construction of the space station.
It is the most advanced robotic device ever sent into space. It is also so long that it had to be folded to fit inside Endeavour's payload bay. And it is so heavy - 3,618lb of aluminium, steel and graphite epoxy - that it could not support its own weight on Earth. Fresh fruit and electrical supplies On Saturday Endeavour docked with the station, bringing Alpha's crew of three their first visitors since they arrived in March for a 4 1/2-month stay.
They did, however, exchange items through an outer station compartment, including mail, fresh fruit and electrical cords. During their 11-day mission, the shuttle astronauts will also attach an Italian-built cargo carrier Raffaello to the station to start unloading 10,000 pounds (4,500 kilograms) of supplies It will be the second of three Italian cargo carriers to be launched to the space station. Leonardo hauled up supplies last month. The space station, under construction since 1998, is scheduled to be completed in 2006.
