2. NDSTaR 2005 Prototype Mars Planetary Suit 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

3. NDSTaR 2005 Prototype Mars Planetary Suit Educational Objectives: Train students in life sciences, with special emphasis on human space flight to help them understand the requirements and difficulties involved with extravehicular activities (EVA) on planetary bodies using Mars as a design case Create ties with the EVA Office at the NASA Johnson Space Center and have space suit experts participating in the project and evaluating students’ ideas Provide extensive hands-on experience to all participating students in different areas of space suit design and manufacturing

4. NDSTaR 2005 Prototype Mars Planetary Suit Outcomes: Delivery of a finished prototype by March 2006 Design and build a space suit that accurately addresses most of the issues the EVA designers have to face to build a planetary suit for Mars Have the students taking active part in its design and construction Develop an Internet site to store all the information and share the progresses made Produce a final report

5. NDSTaR 2005 Prototype Mars Planetary SuitProject Mission Statement Mars-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.

16. Participating Schools

17. 1. Researching Mars climate/geology/etc in the equatorial region. • 2. Identification of known sites of scientific interest with the potential for early human landing access. • 3. Comparing/contrasting these Martian sites with potential sites around DSU, paying close attention to methodology and documentation of selection process, with the identifications of possible sites by the end of October 2005. • 4. Becoming familiar with scientific and construction-type activities we would like to demonstrate with the suit....(DSU may be able to furnish the tools for the demonstration.)

18. 5. Possibility of demonstrating use of suit during simulated surface emergency scenarios. • 6. Researching and emulating NASA suit test methodologies, perhaps in conjunction with Space Studies Department alumni. • 7. Identification of all material and resource requirements in preparation and execution of the test. • 8. DSU will look into the possibility of acquiring simulated Martian dust, to test both components individually and the entire suit.  • 9. DSU will make substantial contributions in crafting the sections of the final report dealing with Martian environment and suit evaluation.

19. North Dakota State College of Science • NDSCS will be doing the machining and prototyping of the suit’s metal parts as; • Enclosure ring • Gloves disconnection rings • Boots disconnection rings • Shoulder bearings rings

20. Turtle Mountain is participating in the project with development of wireless system for positioning determination, voice and video transmission.

30. CONCLUSIONS The project fulfills the new NASA Vision encouraging the students to think about planetary exploration in their lifetime Provides extensive hands-on experience otherwise unavailable in the particular subject of human space flight Increases the interest of North Dakota students in the new Vision for Space Exploration providing them an unique knowledge in a highly needed area, where is a lack of specialists Since the final result of the project is to complete a prototype of a Mars space suit, the students will show more interest and commitment to the project than if the final result was a final report
