EVA 104: Gravity-Offset EVA Space Suit Evaluation


EVA 104 provides an introduction to EVA space suit test and evaluation methods in partnership with Final Frontier Design. Students learn fundamentals of EVA space suit operations and then use the tools and procedures developed in the OTTER EVA 102 or EVA 103 courses. The EVA space suit will be tested and validated in a gravity-offset laboratory environment that can simulate microgravity, lunar, or martian gravity environments. Prerequisites: EVA 101 and (EVA 102 or EVA 103)


Teaching Objectives:

EVA 104 extends upon the introductory life support system curriculum presented in EVA 101 to include specific EVA space suit systems and test and validation procedures. The course covers a historical analysis of specific US and Russian EVA space suit development programs, EVA space suit systems, laboratory test protocols, terminology and etiquette, EVA space suit test development, and design drivers of future EVA space suit systems. Students will be responsible to develop testing procedures based on tools and procedures developed in EVA 102 (Operational Space Medicine), EVA 103 (Planetary Field Geology), or for microgravity operations.

EVA Space Suit Evaluation Program:

Day 1: EVA space suit donning, Assisting donning of EVA space suits. Chest control board operations, cooling, communication and lighting system operations. Introduction to gravity offset systems (Lunar, Martian, and microgravity operations).

Day 2-4: Surface EVA Evaluation, lunar and Martian gravity (scooper, drill, hammer, soil sampler, spectrometer, remote rover operations). Microgravity operations (drill and ‘Task Board 3’ panel removal and maintenance, hatch operations, camera mounting and operation, translation using handrails and carabiners). MCC operations, medical monitoring, and gravity offset system operations. Comparative evaluation of finger, hand, and upper body strength in unsuited, suited and unpressurized, and suited and pressurized environments.
