Purpose:Develop a top-level design for a student built planetary space suit for Mars exploration.Student education and training in space life support systems Build a geographically disparate team across the state


Educational Objectives:Educational Objectives:Train students in life sciences, with special emphasis Train students in life sciences, with special emphasis on human space flight to help them understand the on human space flight to help them understand the requirements and difficulties involved with requirements and difficulties involved with extravehicular activities (EVA) on planetary bodies extravehicular activities (EVA) on planetary bodies using Mars as a design caseusing Mars as a design caseCreate ties with the EVA Office at the NASA Johnson Create ties with the EVA Office at the NASA Johnson Space Center and have space suit experts Space Center and have space suit experts participating in the project and evaluating students’ participating in the project and evaluating students’ ideasideasProvide extensive hands-on experience to all Provide extensive hands-on experience to all participating students in different areas of space suit participating students in different areas of space suit design and manufacturingdesign and manufacturing


Outcomes:Delivery of a finished prototype by March 2006Design and build a space suit that accurately addresses most of the issues the EVA designers have to face to build a planetary suit for MarsHave the students taking active part in its design and constructionDevelop an Internet site to store all the information and share the progresses madeProduce a final report


Project Mission StatementProject Mission StatementMars-analogue research activities on Earth can benefit from a prototype Mars planetary suit that simulates many of the challenges future explorers will face during extra-vehicular activities on the Martian surface. Recognizing the iterative nature of planetary suit development, knowledge gained by designing, constructing, testing, and evaluating such a suit on Earth can be applied to future planetary suit development projects.

To this end, the North Dakota Space Training and Research 2005 (NDSTaR2005) program will develop a Mars-analogue planetary suit that serves the needs of on-going Mars simulation activities. By developing the suit with the participation of other educational institutions in North Dakota, this project also aims to cultivate a knowledge and experience base needed for future space suit development projects.

Ultimately, the fundamental guiding principle of this coordinated effort is to produce the highest quality product delivered on time and within budget.

Team Developed RequirementsTeam Developed Requirements Pressurized to simulate the challenges of operating within a planetary suit. Able to don/off the suit in no greater than [10] minutes. Able to safely ascend and descend a ladder Conduct standard geological field study and construction activities with modified tools Conduct standard geological field study and construction activities. Traverse [45 deg] inclined terrain consisting of loose surface material. Able to operate a motorized rover while seated. Material selection and mechanism design suitable for a Martian dust. Able to quickly remove the helmet in an emergency. Function safely in the suit unaided for [1.5] hours

More Team Developed RequirementsMore Team Developed Requirements

Able to communicate to a remote station with voice and video data. Contain a telemetry system to transmit suit temperature, gas composition, humidity, and toxins measurements. Telemetry system must transmit heart rate and body temperature information. Must be able to accommodate a liquid cooling garment. Excellent helmet field of view. Suit, life support system, other components must be designed to be repairable. Suit must be delivered by [March 2006] to the "customer." Development costs of the suit must not exceed the program’s budget.
