This short grounding cable bundle was an accessory for the Sony Handycam SteadyShot video camcorder used with the Thermal Enclosure System-Crystal Observation System (TES-COS) to record protein crystal growth experiments on the Space Shuttle. It prevented static electricity and power spikes.
The technical team who developed the TES-COS gave the entire device, including this cable, to the Museum in 2012 when they ceased flying the equipment.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
