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

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

NDSTaR 2005 Prototype Mars Planetary
Suit Project 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.

    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

7
More Team Developed Requirements
  • Re-supply of suit consumables in less than 5
    minutes.
  • Able to operate in the suit for 4 hours
    without compromising user health.
  • Able to accommodate a drinking bag for the user.
  • 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 programs budget.

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.

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
