The undocking shuttle Endeavour was delayed
( dpa )- The undocking was delayed by about 20 minutes, due to a minor problem with one of the station's solar panels.
Japan's Kibo laboratory will allow astronauts to perform about 100 experiments that could aid the development of medications and test new materials in the weightless environment. Japanese astronaut Takao Doi is part of the Endeavour crew and helped install the Kibo lab on the station.
The two-armed Dextre robot, which cost more than 200 million dollars, is the final component of the station's mobile servicing system.
