This engineering model of Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) instrument is about to undergo vibration testing in a lab at the Jet Propulsion Laboratory in Pasadena, California. Vibration tests demonstrate the ability of instruments to survive the extreme conditions of both a rocket launch from Earth and a landing on Mars. https://photojournal.jpl.nasa.gov/catalog/PIA24202
