This document summarizes Steven Gantzer's internship at the Cryogenics Test Laboratory (CTL) at Kennedy Space Center. The CTL supports projects involving low-temperature applications and rocket fuel systems. Gantzer assisted with testing procedures and troubleshooting for projects involving liquid hydrogen storage and densification, a rocket test firing, and analyzing lunar soil samples. He gained experience with cryogenic equipment, thermodynamics, CAD modeling, and lab testing procedures.
