The Multi-Purpose Logistics Module Leonardo is lowered toward a scale to calculate its weight for launch.

In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the Multi-Purpose Logistics Module Leonardo is lowered toward a scale to calculate its weight for launch. Leonardo is part of space shuttle Endeavour's payload on the STS-126 mission to the International Space Station. After the weighing, the module will be installed in the waiting payload canister for transfer to Launch Pad 39A. At the pad, the payload canister will release its cargo into the Payload Changeout Room. Later, the payload will be installed in space shuttle Endeavour's payload bay. The module contains supplies and equipment, including additional crew quarters, equipment for the regenerative life support system and spare hardware. Endeavour is targeted for launch on Nov. 14.
