Collection Item Summary:

The technical team who created the Protein Crystal Growth (PCG) experiment equipment provided assembly instructions on this disc.

Astronauts used the Thermal Enclosure System-Crystal Observation System (TES-COS) for protein crystal growth experiments on the Space Shuttle. The surrounding Thermal Enclosure System controlled the temperature for the experiment chambers inside. Better understanding of proteins is important for medical, drug, and agricultural research.

The technical team who developed this equipment gave it to the Museum in 2012 when they began using a later, more advanced model.
