The payload bay doors of the space shuttle Endeavour, housed at the California Science Center, stand open after the installation of a space lab and storage pod on Friday, Oct. 10, 2014 in Los Angeles. The equipment being installed was flown on some missions. A crew on Thursday delicately positioned the 3,000-pound (1,360-kilogram) portable lab and pod inside the orbiter's huge cargo bay. Workers also installed a replica robotic arm, airlock and docking system.
