Express pallets of International Space Station

Dedicated platforms called Express Pallets will accommodate external payload instruments at four locations on the International Space Station. Two will offer zenith-oriented viewing, the other nadir-viewing. Each Express Pallet will provide the interface infrastructure (six adapters) and the resources needed to accommodate several smaller payload instruments. The illustration shows the segment of the Station's Truss (know as segment S3) that will host the Express Pallets; two Pallets are shown accommodated on top. [Image Date: 01-04-97] [97.04.014-002]
