RCA

Summary

This is an unflown specimen of the Apollo Attitude Translation and Control System. The ATCA was part of the electronics suite for the Lunar Module. It accepted inputs from the on-board computer (either the primary Apollo Guidance Computer, or, if necessary, from the Abort Electronics System), and from the Lunar Module's crew actions on the two hand controllers. It directed the firing of the reaction control system of small rockets on the edges of the LM. These small rockets adjusted the LMs attitude (its orientaion in the x,y, and z axes), and they also allowed the crew to move the LM sideways ("translate") as necessary to find a suitable landing site.
NASA transferred this unit to the Museum in 1973.
