The information in this section contains detailed descriptions and technical specifications of the Space Experiment Module carrier system.
Specifications are subject to change without prior notice.
The SEM Carrier System is made up of subsystems which function together to provide containment, structural support, power, experiment command and data storage capabilities for microgravity experiments to be flown in the NASA Space Shuttle. NASA engineers and technicians have designed, built, and tested the SEM Carrier System. The microgravity experiments which fly in the SEM Carrier System are designed, built, and tested by students from Kindergarten through University level. After the student-built experiments are delivered to NASA, NASA technicians integrate these experiments into the SEM Carrier System. The SEM carrier system forms the SEM payload which is installed on an assigned Space Shuttle mission.
