Primary Meeting Topic
Innovation
Definitions
What does Innovation actually mean?• The introduction of something new • A new idea, method, or device • The act or process of introducing new ideas, devices, or
methods
Perceptions about Innovation
• Viewed as the application of better solutions that meet new requirements, inarticulated needs, or existing market needs
• Accomplished through more effective products, processes, services, technologies, or ideas that are readily available to markets, governments and society
• Can be defined as something original and more effective and, as a consequence, new, that "breaks into" the market or society
Perceptions about Innovation
• Generally considered to be a process that brings together various novel ideas in a way that they have an impact on society
• Does this sound like the NSBE mission?

Space SIG Novel Ideas
• Arusha Maintenance – Suit Port Maintenance Glovebox
• Arusha Medical – Robotic Surgical Table• Arusha Exercise – Crew Exercise
Arusha Innovation
• Premise of Arusha: Humanity should one day colonize the Moon
• Phases to Colonize:– Phase 1: Outposts (Apollo, Constellation)– Phase 2: Utilization (Arusha, pilot plants)– Phase 3: Industrialization (manufacturing, businesses)– Phase 4: Colonies (cities)
How Do We Go From Outposts…
To Colonies?
Arusha: Colonization Phase 2
• Arusha is Swahili for “He makes fly (into the skies)”• Innovative design project of NSBE Space SIG
– Commercial/international lunar expansion beyond an initial return to the Moon (next step after Cx/FLO/etc.)
– 48 people living and working on the Moon• Staggered 2-year crew rotations
– Rover transportation required between a primary base at the South Pole and additional facilities across Moon
• Six person crew, lunar circumnavigation capability• 30-day rover excursion mission duration
Arusha Innovation
• Phase 2 introduces the need (new requirement) for global transportation
Example distribution of sites
Lunar Near Side Lunar Far Side
What Does This Mean?Size of the Moon
• Circumference of the Moon: 6,784 miles (10,917 km) –distance to circumnavigate
• Surface area of the Moon: 14,600,000 square miles (38,000,000 km2)– The Moon is:
• 4.68 times the size of the continental United States– 3,119,885 square miles (8,080,470 km2)
• 1.53 times the size of North America– 9,540,000 square miles (24,710,000 km2)
• 1.25 times the size of Africa– 11,670,000 square miles (30,200,000 km2)
• Phase 2 Lunar facilities separated by vast, empty distances
Imagine the continental United States completely
undeveloped except 5 randomly
scattered outposts
Arusha Innovation
• How do we solve this new requirement?– How do humans move on Earth?
• Fly – would require too much rocket fuel• Walk – too far• Ride on animals – animals can’t breathe vacuum• Train – no lunar infrastructure yet• Sail – no oceans or rivers• Drive – only remaining solution
– We need a “car” that can drive all the way around the Moon
Arusha Innovation
• Arusha Long Range Rover– Response to global transportation requirement– New requirements affecting rover
• Circumnavigate Moon within 28-day period– Minimizes the time the crew is in transit and unable to do useful work
• Support 6-person crew for 30 days– Six people allows for enough expertise and personnel to be deployed
to remote facilities
• Operate without support from other lunar assets– Undeveloped lunar infrastructure means no supporting assets will be
nearby
Arusha Innovation
Arusha Long Range Rover Crew Cabin• 10.01 meter (32.85 ft) length• 3 meter (9.84 ft) diameter• Sole living environment for 6 crew for 30 days
Arusha Innovation
• Long Range Rover Requirements give rise to inarticulated needs (later to be documented as requirements)– Rover must be able to self-repair if damaged during an
excursion– Rover must be able to provide medical care for any sick
or injured crew– Rover must be able to counteract the physiological
deconditioning the crew experience on the Moon
Arusha Innovation
– Requires on-board maintenance capability
– Limited available volume in rover
– Starboard side of aft cabin allocated for repair capability
– Includes all stowage for tools and work space for repairs
• Rover must be able to self-repair if damaged during an excursion
Arusha Innovation
• New requirements:– Identified 53 types of failures
that could disable rover and kill the crew if not repaired
– Identified 14 generic maintenance functions required to repair these failures (soldering, etc.)
– Workstation design must accommodates these functions
– BUT…
Arusha Innovation
• Some failed components may be hazardous– Contaminated with toxic chemicals
• Thermal fluid loops and pumps may contain ammonia• Waste Containment System may contain urine and other
biologically active products• Rover or other equipment in proximity to landers may be
exposed to hydrazine– Contaminated with hazardous materials
• Exterior equipment could be coated with lunar regolith– Must not expose cabin interior to these hazards
Arusha Innovation
New solution to address these new requirements
• Suit Port Maintenance Glovebox– Installed on suit port nearest to
Maintenance workstation– Failed component loaded into
glovebox from outside– Crew member repairs
component through glove ports– Component never introduced to cabin interior
Arusha Innovation
• Low fidelity mockup of Suit Port Maintenance Glovebox installed in NASA Multi-Mission Space Exploration Vehicle’s suit port
Arusha Innovation
• Fit check demonstrated basic concept
• Also demonstrated NSBE innovation can be used in NASA rover– If adopted by NASA may
increase survivability of MMSEV on Mars
• Medium fidelity mockup under construction for actual repair tests
Arusha Innovation
• Rover must be able to provide medical care for any sick or injured crew– Evacuation of injured crew
not an option – must treat any condition onboard
– Limited available volume in rover
– Port side of aft cabin allocated for medical capability – Includes patient
treatment and all stowage
Arusha Innovation
• Must be able to provide both medical care and maintenance repairs simultaneously
• Any portion of a crew member’s body (or multiple portions) may require medical treatment– Requires caregiver to have access to all parts of the
patient’s body• In prior NASA studies has resulted in requirement for caregiver
to be able to walk around all sides of the surgical table• Not possible in Arusha rover due to small size of vehicle (would
intrude in maintenance work volume)
Arusha Innovation
New idea – since cannot bring caregiver to patient, must bring patient to caregiver: Robotic Surgical Table
• Patient treatment table nominally stowed beneath floor and raised for use
• Table is a robot that is articulated to reposition patient as needed to present area of injury to caregiver– Table is subdivided into articulating secetions

Arusha Innovation
• Robotic Surgical Table must accommodate 1st percentile Japanese female to 99th percentile American male in all relevant anthropometric dimensions– Significant range in dimension – will move relative
positioning of joints• Each element must be capable of expanding
or contracting in length and width to meet anthropometry requirement– Surgical table will literally be a different size when
different crew members use it

Arusha Innovation
• Each element to element interface is either static or a joint
• Actuators reposition elements at joints to transform surgical table for different body postures
• Each actuator must be capable of fine positioning and lock to support weight when stopped
• Elements not connected by actuators (static interfaces) should physically support one another when adjacent and mitigate flopping / cantilever effects

Arusha Innovation
• Rover must be able to counteract the physiological deconditioning the crew experience on the Moon– Each crew member
requires ~2.5 hours scheduled exercise per day
– Limited volumes allocated for crew exercise capability
– Devices must stow when not in use
Arusha Innovation
• NASA currently flies exercise equipment on ISS to address: aerobic conditioning, muscular conditioning, bone loss, sensorimotor, psychological, and decompression sickness– Met by 3 devices: ARED (universal gym), T2 (treadmill),
and CEVIS (cycle ergometer)– Dedicated volumes provided on ISS
• Arusha innovation challenge is to replicate this capability for 6 crew in a smaller volume
Arusha Innovation
• Solution to address aerobic, sensorimotor, psychological, and DCS is a COTS-derived treadmill– Must mount under the floor in the mid section
between the body hygiene system and waste containment system
– Requires modification to COTS device• Mount so top of belt is flush to surface• Remove control panel/devices and integrate in walls• Provide user stabilization to allow use during vehicle
motion
Arusha Innovation
• Solution to address muscular and bone loss is a custom resistive exercise device– Must mount in aft section, aft of medical
and maintenance work envelopes– Load paths must be negotiated with Cabin
Structures– Must assemble/disassemble in less than
30 minutes– Must also allow use during vehicle motion
Arusha Innovation
• Open questions– Is there room for more than one aerobic or resistive
device?– Does the rover also need a cycle ergometer?– Can a custom resistive device provide high enough
loads?– Can a COTS treadmill that fits in the rover provide a fast
enough speed?
