The advanced technology laboratory

The Advanced Technology Laboratory (ATL) utilizes the Space Shuttle and the European Spacelab and is intended for advanced space technology. The evolution of the ATL concept is outlined along with its current status. Spacelab payload point design studies are reviewed as related to objective; physical layout; mission analysis; pointing accuracy; attitude management and fuel consumption; controls, displays, and data management; and thermal control. These studies aim at increasing the knowledge of the best techniques for integration and operation of payloads in the Spacelab and the Shuttle. ATL presents a dynamic new research potential, capable of accomodating 8 to 15 experiments per mission.
