Bioastronautics: EVA Space Suit Evaluation

This course covers the requirements and design considerations for EVA systems and tools for conducting planetary field geology. Included are an introduction to field science in the context of geology; an overview of the processes that shape the surface environments of Mars and Earth’s moon; a survey of historical planetary surface geologic exploration by robots and humans; and a survey of historical EVA systems and tools used for human surface science. Emphasis will be on analyzing the constraints placed by human factors, the EVA environment, science tasks, etc. upon the design and implementation of EVA suits, tools, and procedures for effective and efficient field science operations on planetary surfaces..

The online portion of the EVA 103 course will be followed by a ~1-week capstone field experience in the San Francisco Volcanic Field (SFVF), just north of Flagstaff, AZ. This area has been used extensively in the past for a number of NASA analog mission simulations and NASA-funded geologic research related to planetary field exploration. Students will be introduced to basic field science practice in the context of geologic observations and sample collection. Field work will also involve testing of prototype surface EVA suits and tools in the scientifically relevant analog setting of the SFVF.

EVA 102 participants will learn about space medicine, wilderness medicine, human performance, leadership and psychological resilience. The course will dedicate a special focus to extreme environment & wilderness medicine, and how the spaceflight environments may inform triage and first aid scenarios. The on-site portion of this class will focus on wilderness medicine in extreme environments, culminating with a 4.5 on-site lab portion devoted to triage, scenarios and skills pertaining to wilderness medicine. Basic and Advanced First Aid certifications and graduation from AST 101 and EVA 101 are prerequisites to EVA 102.

It is anticipated that at the end of this course, participants will have gained 1) basic knowledge and understanding of space medicine and physiology, specifically the space environment as it pertains to human health pre-, post- and in-flight, 2) an appreciation of extreme environments and how they inform space exploration, and 3) a basic understanding of, and be able to demonstrate basic competency in skills related to wilderness medicine and outdoor survival.

AST 102 provides a foundation in the microgravity environment, microgravity research campaign planning and operations, microgravity experiment and payload design and development, and science communication and public outreach.

Students in the course will apply their knowledge and skills learned in the webinars in a parabolic flight campaign with Integrated Spaceflight Services and the National Research Council of Canada. The flight campaign will take place at the NRC Flight Research Lab (FRL) located in Ottawa, Canada. The address is 1920 Research Private, Ottawa, ON K1V 1J8, Canada and is suited within walking distance of the Ottawa International Airport. Students should plan to arrive at 8AM each day. A typical day will end by 6PM. Students should plan to stay until 6PM on the last day of the campaign. Additional details of the flight campaign will be provided in the webinars.

Students will need to provide the following information one month prior to the flight campaign:
• Full legal Name
• Date of Birth
• Nationality
• Passport Number and scan of passport photo page

Notes on COVID-19:
• The NRC is a Government of Canada agency and we will comply with all Canadian health regulations regarding COVID-19.
• Students are advised to monitor the travel restrictions regarding the US/Canada border.
• Students in need of travel visas should contact the Instructor as early as possible.

What to expect

Participating members should allow for four to five days.  Upon arrival, each members will receive a safety briefing and instruction on research protocol as part of the Test Readiness Review (TRR). Members participate in egress tests and system testing.  All teams will rehearse until they reach a level of proficiency in 1G conditions before their flight.  Once the mission is approved by both test director and NRC flight safety officer, the flight will commence.

.

Mission Plan:

Each sortie is planned for 18 parabolas, but flights may be terminated for reason. A flight may be terminated  for any of the following reasons:

1. Test participant vomiting in the suit or bio-monitor data in excess of established limits
2. Excessive vomiting by any flight team member.
3. Failure of essential equipment
4. Any condition created by a flight team that violates any safety protocol

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.

Instructors: Ken Trujillo, Chris Lundeen

BIO 104 provides instruction on spacesuit use in nominal and off-nominal post-landing environments. Students demonstrate reliable functionality of parachute release, life preserver unit (LPU), and snorkel functionality in varying sea and lighting conditions. Students also learn the effective use of radios, beacons, signal flares, and other signaling devices in water and egress bottle use for egress operations.
