Description


Apollo Command Module Earth Landing Sequence Controller, measuring 8.25″ x 4.5″ x 3″, bearing a large parts tag affixed to the top, reading: "Item Name: Sequence Controller, NAA Control No. ME 901-0001-0019, Contract No. NAS 9-150, NAA Inspection Serial No. 06398A809354, Manufacturer: Northrop Ventura, Mfr Serial No. 18, Mfr Part No. R6920-517." The underside has a hexagonal plate engraved "Current Equalizing Module." The unit has four connector ports labeled “J1” through “J4,” and a blue “Static Air” port. A worn handwritten tag is affixed to one side. In fine condition. Part of the Apollo Command Module's sequential events control system, the controller was employed during spacecraft reentry to sense barometric pressure, and automatically trigger firing pyrotechnics that released the Apex cover, drogue, pilot and main parachutes prior to splashdown.

Due to the size, weight, and/or fragile nature of this item, we ask that you call RR Auction for a shipping quote.
