Apollo Emergency Detection System (EDS) Rate Gyroscope Package, measuring 7″ x 6.75″x 3.5″, with a Marshall Space Flight Center tag on the top, reading: "Control EDS Rate Gyros, Pt. No. 50Z35021-7, Mod. No. AAT-1A, Ser. No. 1006, Wt. 10.8 lbs., Mfd. by Northrop Electronics Division, Cont. No. NAS8-14000." One side has a red-capped port, and another features a meter indicating "0496 Hours." The top has an affixed label indicating "Flight Direction." In very good to fine condition. This triple-redundant rate gyroscope package (nine gyroscopes, three for each axis) was designed to detect if the Saturn V was moving too quickly in any axis. It was part of the system that would warn the astronauts and ground controllers about abnormal movement and would also feed those signals to the EDS if an automated abort was determined to be necessary.
