EVA-EXP-0072 This document does not contain any export control information (#20205009476) 15

Objective

• Determine the applicability of utilizing an Exosuit for Exploration EVA evaluations, including xEVA 

Informatics and xEVA Concepts of Operations

Mission Implementation & Summary

• Conducted training runs in the Exosuit with both experienced and new pilots

• Utilized the EVA aquatic pressurized task board for both training and pioneering tasks

• Pioneering tasks executed by EVA SME (Coan) and Science SME (Graff)

• Pioneering tasks executed by 3 EVA-experienced astronauts (Feustel, Pesquet, Kanai)

• Made preliminary notes about conducting science observation tasks

• Science observations examined by an scientist-astronaut (Feustel) and Science SME (Graff)

Crew Debrief Comments

• Exosuit is similar to EVA in a lot of ways, but not in relation to the hands 

• Value of Exosuit is concentration, focus, making several things work together – good skill for operators 

to have

• Lends more to general crew training than realistic flight-specific training or evaluating tools and 

techniques

• If looking at 2024, need to find a way around the hands limitation (pinchers) in order to handle 

objects and use relevant tools or scanners – would be much better if able to use the lunar geology 

sampling tools (made by EC7/EVA Tools)

• Need to be able to conduct science operations with Exosuit [i.e., operate in clear water near relevant 

geology]

• Flying instead of walking in Exosuit is not as bothersome (from astronaut perspective)

• Could spend up to ~2 hours in suit – need to learn how to take breaks

• Should get assets together in proximity operations due to the complexity it adds to the decision 

making process – potential of impacting is more realistic and good, but adds to risk
Utilization of Exosuit for xEVA

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 16

Results (Key Take-Aways)

• Exosuit provides a reasonable platform for xEVA informatics development and testing

• Using a HUD (e.g., Lumus DK-52) in the Exosuit worked well

• Suit mobility is different from an Exploration Spacesuit (e.g., xEMU), and lack of dexterous 

fingers is a limitation 

• Exosuit may be viable for early generic training for lunar surface EVAs

Recommendations

• Evaluate HUD display, information, and layout with DK-52 in Exosuit

• Operate Exosuit in clearer water near more relevant geology (i.e., out of USC cove) and utilize 

for science ops, specifically contextual observations

• Incorporate pre-hensors (fingers) when those become available (currently in development by 

Nuytco and NAVSEA)

• Utilize the form-fitting Lightweight 1ATA Dive Suit (LADS) being developed by Nuytco and 

NAVSEA when/if it is completed

Lunar 2024 Relevance

• As stated in the crew debrief, the Exosuit and NXT are not directly relevant to the Artemis 3 

mission (2024)

• Training crew to conduct scientific observations while wearing a restrictive suit is relevant to 

all lunar surface missions

• Development of xEVA informatics is relevant to lunar surface missions subsequent to the 

initial 2024 mission, and potentially even for the Artemis 3 mission

Lumus DK-52 as an xEVA Informatics HUD Capability Concept Platform

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 18

Objective

• Evaluate the applicability of the Lumus DK-52 glasses as an Informatics system (heads-up display) for xEVA 

capability testing

Mission Implementation & Summary

• During most Exosuit events, the Lumus glasses were utilized to display varying amounts of information

• Data was displayed in two scenarios, generic and task specific

• For generic: a local map, compass, suit data, clocks, turns, and anticipated gauge readings were displayed

• For specific tasks: cue cards were projected for pioneering task direction on task board

Crew Debrief Comments

• Heads-up display is a good tool [for lunar surface EVA operations]

• Value of pushing data to a HUD (e.g., Lumus glasses)

• Everything seen was of value (map, compass, suit data, clocks, turns, gauge readings, cue cards)

• Needs to be a way to acknowledge steps in procedures 

• Visual representation (graphic) of data was valuable

• Step by step instructions/procedures were not as valuable, as there is still a need to acknowledge 

steps with someone

• Need to have CAPCOM pushing cue cards to the HUD from MCC or have two crew sitting side by side at IV 

workstation

• Nav was great in suit

• A 3D map that can be tagged with specific locations and shared between MCC and assets would be 

beneficial 

• Integrate activity statusing (PET start/stop) into EVA informatics

• Lumus glasses were great for Exosuit, not so much for DDW sub 
Lumus DK-52 as an xEVA Informatics HUD Capability Concept Platform

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 19

Results (Key Take-Aways)

• A heads-up display is valuable and useful

• Beneficial data included suit data (consumables, gauge readings, umbilical turns) and navigation 

information (map and compass)

• Task-specific cue cards projected via a HUD are advantageous 

o Graphics were intuitive

o Step-by-step instructions were not seen as being as helpful, especially given that critical 

steps need to somehow be actively acknowledged/statused

• Content needs to be optimized for EVA operations

• Need to understand who is in control of pushing content to the HUD based on the task or time

• Lumus glasses worked well in both the Exosuit and DDW sub, however they were uncomfortable for 

extended periods of time (~ >1 hr) in the DDW due to the comm headset being used

Recommendations

• Continue evaluating HUD-like concepts for xEVA informatics

• Conduct in-depth studies and tests to understand the amount of data needed and required

• Incorporate lessons learned into helmeted testing (e.g., DAVD in KM37)

Lunar 2024 Relevance

• Development of xEVA informatics with a HUD-type display system is potentially relevant to the 

Artemis 3 mission (2024, and definitely relevant to subsequent lunar surface missions (Artemis 

phase 2)

• A capable xEVA informatics system will allow for both increased crew autonomy and for enhanced 

interaction with a Earth-based Science Team

Objective

• Assess the xEVA Aquatic Pressurized Task Board for evaluations of xEVA Informatics (Lumus DK-52 

in the Exosuit)

Mission Implementation & Summary

• Placed via crane in 20 ft of seawater without issue

• Subjects in Exosuit operated board and executed procedures displayed via Lumus glasses

• Divers reconfigured board as needed

• Board was evaluated by each crew member

Crew Debrief Comments

• Some of the valves were difficult to operate in the Exosuit

• Some crew enjoyed the challenge, others did not

Results (Key Take-Aways)

• The task board worked as designed and provided a great platform to allow the evaluation of a 

heads up display in a suit

Recommendations

• Utilize the pressurized task board for future Exosuit training and for other aquatic analogs (e.g., NBL 

and NEEMO) 

• Redo the labels to make hard mounted

Lunar 2024 Relevance

Utilizing Dual DeepWorker for xEVA Evaluations

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 24

Objective

• Determine the applicability of utilizing a Dual DeepWorker for Exploration EVA evaluations, 

including xEVA Informatics and xEVA Concepts of Operations

Mission Implementation & Summary

• Dual DeepWorker used on excursions as a “rover”

• Positions in DDW included Pilot and Flight Engineer (pilot qualified)

• Passengers were taken in DDW, however Observer role (non-pilot science expert) was not exercised

• Lumus DK-52 attempted early on as a HUD for the Flight Engineer, but uncomfortable to wear for 

extended periods of time (functionality was replaced with an iPad solution)

Crew Debrief Comments

• Operating DDW

o Shouldn’t do stuff up the wall [vertical plane], since won’t be flying on the moon

o Doesn’t really drive on bottom and doesn’t add any extra value [to drive with wheels]

o Using wheels and only driving on bottom is more realistic

• Informatics

o Lumus glasses on Flight Engineer was not a good setup – pilot needed info 

o Tablet worked better for pilot than Lumus glasses ergonomically

o Solutions for suit and sub are different – Lumus glasses were great for suit, not so much for 

sub 

• Navigation

• Nav on the Flight Engineer side was misplaced – pilots needs that info more
Utilizing Dual DeepWorker for xEVA Evaluations

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 25

Results (Key Take-Aways)

• DDW can be used for longer traverses with science context observation tasks

• Need to get closer to rocks for science

o DDW doesn’t allow crew to get up close

o Could get closer in Exosuit

• Real-time video was valuable for MCC and Science Team

• Requires umbilical in order to transmit data back and forth

• Tethered operations were more valuable and relevant than untethered

Recommendations

• Use the DDW as a platform for evaluating rover operations that are focused on science 

contextual observation tasks

• Utilize data tether in order to transmit data back and forth between DDW and MCC, 

much like would be in actual spaceflight

Lunar 2024 Relevance

• Not directly relevant to Artemis 3 mission (2024)

• Relevant to Artemis Phase 2

• Enables examination of utilizing a rover for science observations on subsequent 

Artemis missions

Exploration Capability at NXT

• “Sub [DDW] was better [than Exosuit] because of its 

"unlimited" range [due to Exosuit being restricted to 

the USC cove]”

• “It felt real...to be out there [in the DDW]...actively 

looking for things and discovering the landscape as we 

went”

• “Staying in the cove made the suit less of an asset, in 

strict terms of exploration”

Con Ops Development at NXT

• “It's too easy with just the sub”

• “Interaction, relative navigation of the two assets, 

challenging com setups when both were interacting 

was the interesting ops”

• “Need two heterogeneous assets to make progress ”

Crew Training at NXT

• “The sub is just too easy”

• “The suit, on the other hand, is challenging at the 

beginning”

Potential mission with DeepWorker but w/o an Exosuit

• “It’s still valuable, but less”

• “DeepWorker is too comfortable and relaxing”

• “Exo is not like EMU we have in space but it gives 

physical discomfort and mental/psychological 

challenge to manage the life support systems, requires 

attention/focus which is similar to the space walk”

• “Winning ticket is really a combination of both [Exosuit

and DDW], especially seen from the control center / 

operations point of view”

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 28
Objective

• Evaluate EVA science sampling tools during land-based geology tasks

Mission Implementation & Summary

• The crew were briefed on the tool set and EC7s plan for developing Artemis geology tools in 

FY20

• Crew evaluated each tool in geologically interesting areas

Crew Debrief Comments (a few examples)

• Consider smaller rake head

• Add a feature to the tongs that allow them to remain locked in open position

• Consider adding a stop to the hammer to prevent it from being flung out of hands, or ridges 

that match profile of fingers like a steering wheel

Results (Key Take-Aways)

• Great feedback was received and recorded

Recommendations

• Continue bringing EVA tool prototypes to analogs to get crew evaluations

Lunar 2024 Relevance

• The crew feedback received on these tools will be taken into consideration during

Exploration Science Training

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 31

Objective

• Conduct terrestrial Exploration-relevant geology training 

• Tie terrestrial geology (‘turf’) to subsea geology (‘surf’)

Mission Implementation & Summary

• A local geology expert and XI planetary scientists conducted geology field training with 

crewmembers on foot and by vehicle (island-wide)

• Crew used small boats and kayaks to observe geology near sea-air boundary not accessible by foot

Crew Debrief Comments

• Moon geology doesn’t look anything like this geology

• 1 week of geology before coming here – need basics before getting here

• Just do 1 geology day here on island

Results (Key Take-Aways)

• Complex geology enabled science observational skills and general field skills

• The crew’s geologic expertise ranged from minimal to PhD; need to account for skill diversity and 

provide additional procedural based-approach to geologic tasks (observations and sampling) that 

transfer to sub-sea tasks

Recommendations

• If returning to Catalina, use complex geology to continue to train general field geology and science 

ops skills

• Potential for additional NXT locations with better representative surf-turf geology (ex. Hawaii)

Lunar 2024 Relevance

• Geological training/ops in complex geological areas is relevant to all lunar surface missions
Utilizing Topside Capabilities (MCC & IV) for xEVA Evaluations

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 32

Objective

• Assess the topside/shore capabilities and positions for enabling EVA objective evaluations

Mission Implementation & Summary

• Used Nuytco workstation as a partial IV workstation

• Partial MCC set up away from dock

Crew Debrief Comments

• MCC

• Need mission direction to be provided from MCC – too many people on dock and 

decisions made on dock

• Communication

• Everybody with a hot mic on the same loop is not realistic (topside, support, boats, 

mission, etc.)

• For MCC, want to have ability to select comm loops, like we do now

• Must have consistent comm and data exchange between the crew and MCC [i.e., 

DeepWorker needs fiber optic connection]

• Once assets are deployed everyone should be up in MCC on same mission loop talking 

with each other

• Navigation

• Nav was intermittent in MCC (at times)
Utilizing Topside Capabilities (MCC & IV) for xEVA Evaluations

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 33

Results (Key Take-Aways)

• MCC

o Configuration in USC’s Boone house worked for an MCC

o Capabilities of pushing data to the assets needs to be enabled in MCC

• Communication

o Communications, video, tracking, navigation and data channels were demonstrated

o Lessons learned for further work to tie all of them into the integrated operations scenarios

o Communications between MCC and the assets where noisy and not completely reliable throughout 

the mission

o Communication between assets was not always solid or reliable – areas for future improvement 

noted

• Navigation

o Navigation was intermittent at beginning, but improved as mission progressed – needs to be 

reliable to enable exploration con ops

Recommendations

• Evaluate full MCC leading mission

• Ensure comms are reliable to and between assets

• Configure MCC to be able to push data to the assets

• Use DeepWorker in fiber optic tethered configuration in order to transmit data back and forth

• Conduct an engineering run with core team to ensure everything functions properly

Lunar 2024 Relevance

• MCC and comm capabilities are relevant to Artemis 3 (2024) and subsequent missions

• Navigation will be needed on later, longer missions
Objectives Completion Status: Topside Capabilities (MCC & IV)

Location (Catalina and USC) Lessons Learned & Recommendations

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 35

• Infrastructure at USC-Wrigley Marine Science Center is well-suited for enabling 

this type of operation, and deployment effort is reasonable (e.g., travel, 

logistics, etc.), though there are challenges with the isolation of the facility 

(access, transportation, lack of hardware store, lack of general store, etc.)

• Crew debrief comments:

o Take general path, which is great here, but geology is not what will find on 

moon – if want a moon analog, take it to Hawaii

o Good for general training, not specific for moon

• Visibility was not good near USC cove 

• Not able to operate Exosuit beyond USC cove area where water is clearer and 

deeper due to constraints on anchoring a boat/barge

o Not going to be able to get the Exosuit to “exploration” quality terrain 

w/o a ship

o Ship must be anchored to deploy the Exosuit

o Areas scouted with exceptionally high quality sites, such as Sea Fan 

Grotto, are in a protected zone where anchoring is not permitted

• Not able to have the Exosuit and DeepWorker work together, which was a 

major component of the model
Summary and Recommendations

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 36
Exosuit Atmospheric Diving System/Suit (ADS)

• Exosuit provides a reasonable platform for xEVA informatics development and testing

• Using a HUD (e.g., Lumus DK-52) in the Exosuit worked well

• Exosuit is similar to EVA in a lot of ways, however suit mobility and pinchers (lack of fingers) are not equivalent to an Exploration Spacesuit (e.g., 

xEMU)

o If looking at 2024, need to find a way around that limitation

o Incorporate pre-hensors (fingers) when those become available (currently in development by Nuytco and NAVSEA)

o Utilize the form-fitting Lightweight 1ATA Dive Suit (LADS) being developed by Nuytco and NAVSEA when/if it is completed

• Viable for supporting aspects of training for lunar surface EVAs

o Value of Exosuit, focus and compartmentalization, a lot effort to be task loaded – good skill for operators to have

o Per experienced astronauts, “If you target crew training as part of the objectives, you need the suit”

o Need to operate Exosuit in exploration quality terrain (beyond USC cove in areas where water is clearer and deeper)

Dual DeepWorker Submersible

• Was valuable as a platform for evaluating rover operations that are focused on science contextual observation tasks 

o Useful for exploration capability development

o Can be used for some training of observational science operations 

o Good for exploration traverses, but is too easy to pilot for some aspects of crew training

• Was not able to get close enough to the rocks for detailed geological descriptions

• Tethered operations were more valuable and relevant than untethered – allows for real-time video and data exchange with MCC and Science Team

• Doesn’t really drive on the bottom and it doesn’t add any extra value to have wheels (which may have been an artifact of the weigh-out), though ops 

should be on bottom to replicate rover on lunar surface

Summary of Results for EVA Equipment and Geology Training

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 38

xEVA Informatics (Lumus DK-52)

• Lumus DK-52 worked well for xEVA testing

• DK-52 system worked well in the Exosuit, but not as well in the DeepWorker, primarily due to fit/comfort issues 

(“Lumus glasses were great for suit, not so much for sub ”)

• EVA-experienced astronauts stated that a HUD would be a useful EVA capability for lunar surface missions

• Lumus not a good setup for the Flight Engineer (tablet/iPad worked better)

Lunar Geology Tools

• Baseline lunar geology tools worked well

• Operator feedback received from astronauts is driving changes to tools for Artemis

Geology Training

• Allowed for training of science operations and general geology field skills

• Geological processes in Catalina were not similar to the moon

• Complex geology enabled development of science observational skills
Summary of Results for NXT FaM and Mission Location (Catalina) 

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 39

NXT FaM (general)

• Demonstrated feasibility of conducting a mission analog utilizing subsea vehicles

• Provided initial look at a HUD system for xEVA informatics capability development

• Need to train people about risks during ops [with Exosuit and DDW flying in proximity]

• Difficult for Nuytco team to run simultaneous operations while attempting to troubleshoot various systems on two 

different assets

Catalina Island (USC)

• Subsea and terrestrial geology exists to potentially provide meaningful exploration scenarios

o However, the geology in Catalina is not directly relevant to the lunar surface

• Communications, video, tracking, navigation and data channels were demonstrated

o However, further work is needed to tie all of them into a reliable integrated operations scenario

• Infrastructure at USC-Wrigley Marine Science Center enabled operations, and deployment effort is reasonable

o There are challenges with the isolation of the facility (access, transportation, lack of hardware store, lack of general 

store, etc.)

• Underwater visibility was poor near USC cove 

o Not able to operate Exosuit beyond USC cove in exploration quality terrain (areas where water is clearer and deeper) 

due to constraints on anchoring a boat/barge that would be required for Exosuit deployment
Findings for NXT Concept

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 40

NXT Concept

• Allows for exploration analog missions that trains crew on 

complex terrestrial geology (‘turf’) and then extends that 

experience into exploration techniques into a subsea 

operationally challenging environment (‘surf’)

• Enables development of Exploration capabilities and con 

ops

• Provides generic exploration training and expeditionary 

skills

• Operations run per sortie (i.e., part task), not a continuous 

immersed mission over several days (as in a spaceflight)

• Concept “not so valuable for 2024 mission”, however could 

help develop “the 4-T’s for missions later than 2024”

• Assets provide mentally taxing operational challenges 

o Exosuit operations enabled evaluation of xEVA 

informatics display concept

o DeepWorker operations allowed for science 

observations on longer traverses, similar to a rover, 

but was almost too easy to fly

• Exploration Capability Development

o Exosuit was critical for technology development, such 

as an EVA HUD

o DeepWorker enabled longer traverses and 

development of science ops

• Exploration Con Ops Development

o For crew, interaction of an Exosuit and DeepWorker 

would be the critical aspect

• Exploration Crew Training

o Per the crew, the Exosuit was the critical component 

for training (physically and mentally challenging)

• Value for NASA

o For READy, allows for mission to evaluate sorties and 

specific techniques and technologies

o For EVA, provides an intense operational environment 

to examine use of informatics

o For ARES, provides an environment with complex 

geology to further train crew on field geology and 

science operations

o Need to understand cost of mission as compared to 

other analogs in order to asses the “bang for the 

buck”
Relevance of NXT to Artemis

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 41

Relevance to Artemis Lunar Surface Missions

• NXT does not directly address the Artemis 3 (2024) mission, but may be useful for developing and training 

general lunar operations and crew training experience (applicable to Artemis Phase 2 concepts)

o Suit not representative of xEMU in terms of mobility (walking) and hands (lack of fingers)

o DeepWorker mimics a pressurized rover, which will not be on first mission(s), but is planned for Phase 2

• Training crew to conduct scientific observations while wearing a restrictive suit is relevant to all lunar surface 

missions

o Exosuit provides physical and mental challenges similar to a spacesuit

o Enables operator skill training in focus and compartmentalization

o Limitations (hands especially) need to be mitigated if developing con ops for a 2024 mission

• Training crew to conduct scientific observations while flying a submersible is relevant to all lunar surface 

missions that have a rover

o Dual DeepWorker allows for crew to perform detailed geological observations while simultaneously 

maneuvering in an extreme environment and maintaining life support systems

• Development of xEVA informatics is relevant to lunar surface missions subsequent to the initial Artemis 3 

mission
Recommendations for NXT and Potential Future Missions

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 42

NXT Concept

• Change emphasis of NXT to focus missions towards crew experience, early general exploration training, and generic 

science observation skills

• For Exploration Capability Development:

o Utilize the Exosuit for xEVA informatics evaluations (HUD display, information density, layout, etc.)

o Utilize the DeepWorker for assessing rover-based science operations on longer traverses, incorporating the 

fiber optic tether in order to transmit data back and forth between DDW and MCC to be more spaceflight 

relevant

• For Exploration Con Ops Development

o Utilize the Exosuit for examining data transfer to/from EVA crew, and evaluate information density and layout

o Evaluate the interaction between an Exosuit and DeepWorker during dual asset operations

• For Exploration Crew Training

o Utilize the Exosuit as a complex asset that provides both physical and mental challenges, and incorporate 

geology contextual observations

o Use the DeepWorker for additional crew experience in cockpit resource management 

• Schedule an engineering run prior to the mission for core team evaluations and to ensure assets are functioning as 

needed, and set up reliable com and data transfer between the assets and MCC
Recommendations for NXT and Potential Future Missions

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 43

Mission Operations

• Staff a ‘full’ MCC that leads the missions

• Incorporation a Science Team to make tactical and strategic decisions

• Conduct dual ops with both the Exosuit and DDW

• Reduce the number of daily sorties and make them longer

Location

• Scout locations more geological features more relevant to lunar surface operations

• Operate Exosuit in clearer water near more relevant geology (i.e., out of USC cove)

Fiscal Year 2020

• Capability was demonstrated at the Feasibility Mission, but resources and team bandwidth should be focused on testing that is

directly relevant to Artemis 3 (2024)

• If the READy MMT/core team unanimously determines that the best use of resources is to run an NXT mission in FY20, then:

o EVA (XX): Support during engineering run and mission as EVA SMEs, integrate any EVA objective with the assets, and 

participate as asset pilots and support divers (including as NEEMO Dive Safety Board member)

o ARES (XI): Support during engineering run and mission as Science SMEs, conduct surface geology portion of mission, 

participate as asset pilots and support divers

o EVA Tools (EC7): Support during engineering run and mission, and participate as asset pilots and support divers

NXT Concept Lessons Learned & Recommendations (Astronaut Comments)

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 47

o Valuable for development, but concern about how it relates to 2024

o NXT gives a place to look at generic exploration concepts (different kind of ops concept 

than ISS) – new tactics on how to plan missions and push data

o Need to develop skills and technologies for exploration

o Data exchanges between science room and operators

o Can’t develop geology tools here, because don’t have a realistic suit here

o Would be great to be able to pick up geology tools and do sampling underwater

o Tools: HUD, data, comm links between assets, sharing of info between assets, manipulator 

on rover, more about exploration concepts for data push/exchange

o Only 2-3 NXT missions before 2024, so maybe not so valuable for 2024 (a bit late for 2024) 

o The 4-T’s for missions later than 2024

o Utilization of Exosuit

▪ Exosuit similar to EVA in a lot of ways, but not in hands

❖ If looking at 2024, need to find a way around that limitation

❖ Can barely hand between assets, and no way to use tools or scanners

❖ Would be great to be able to pick up geology tools and do sampling 

underwater 

❖ Biggest limitation of entire analog

▪ Flying instead of walking in Exosuit is not as bothersome from astronaut 

perspective, it’s the hands

▪ If able to pick up tools (like what EC7 made) it would be so much better

▪ Exosuit lends more to general crew training than evaluating or training tools and 

techniques

▪ Could spend ~2 hours in suit – need to learn how to take breaks

▪ Need to be able to conduct science operations with Exosuit

▪ Need to get assets together, though now worried about proximity – potential of 

impacting is more realistic and good, but adds to risk (liability)

▪ Exosuit good for general training, not realistic training

o Hard hat diving system would be helpful

o 3-4 runs in water to get to point of enough training to do exploration tasks

o Crew rotated through roles, but should have specific dedicated roles (as in an actual 

mission)

o Could see more in depth geology training before coming to NXT. You learn theory and then 

come here to learn specifics. Requires several days/week of geology

o For the Exosuit, could be susceptible to injury (e.g., shoulder) – risk of limb injury, would be 

good idea to train people about risks during ops (different from EMU)

o Dock master is doing mission director and cove coordinator – need to separate the two 

o Support team needs to have assigned roles

o ESA comments are important for any NXT mission

o Exploration Capability: 

▪ Sub [DDW] was better [than Exosuit] because of its "unlimited" range [due to 

Exosuit being restricted to cove]

o Con Ops Development: 

▪ It's too easy with just the sub

▪ Interaction, relative navigation of the two assets, challenging com setups when 

both were interacting was the interesting ops

▪ Need two heterogeneous assets to make progress 

o Crew Training: 

▪ The sub is just too easy

▪ The suit, on the other hand, is challenging at the beginning

▪ If you target crew training as part of the objectives, you need the suit – should find 

a way to increase its range for exploration purposes

o Potential mission with DeepWorker but without an Exosuit

▪ It’s still valuable but less

▪ DeepWorker is too comfortable and relaxing 

▪ Exo is not like EMU we have in space but it gives physical discomfort and 

mental/psychological challenge to manage the life support systems, requires 

attention/focus which is similar to the space walk
NXT Concept Lessons Learned & Recommendations (Team Comments)

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 48

• ESA

o NXT will not be able to prepare for 2024, but useful to prepare for a sustainable set of 

operations on the Moon in the next decade

▪ Should not focus on 2024

▪ Geology in Catalina not relevant (“this isn’t the moon”)

▪ Not representative suit

▪ Should focus on crew training experience

o Need mission that enables scientists to be in MCC and support crew like they would in 

realistic mission

o Geology part should be more focused and intensified

▪ Should go somewhere that we know something is there, not try to make it work 

based on what’s around

▪ Only did description, missing other pieces of geology puzzle

▪ Need to go all the way with geology story – observation, exploration, sampling, 

review of sample

▪ Need more training on geology

o Keep assets as is – fly, not drive, the DDW

o Crew needs to be out in assets on excursions, and engineers and scientists need to be in 

MCC

o Need to have mission management in MCC at all times

▪ Need to protect position in schedule

▪ Schedules deviated after morning meeting, roles changes, with no coordination 

amongst team

o Recommendation for potential future NXT missions:

▪ Run as geology operational training for astronauts in a complex geological 

environment with geologists support in MCC

▪ Add in significant geology training (classroom, rocks, field trips and traverses with 

sample collection) to give crew the geological awareness for understanding the 

environment with scientist support

▪ Keep the assets as they are to optimize their use and benefit from their space 

vehicle like complexity, safety management, and operation in an hostile 

environment

▪ Use the DeepWorker as the sample collector (robotic ops) and the Exosuit as a 

vehicle to recover the samples from the sub basket to bring them back into preassigned separated sample containers

▪ Set up reliable com and data transfer between the assets and MCC

▪ Have a sustainable team of geologist in MCC to support the crew every day

▪ Ensure clear exploration objectives underwater for relevant and interesting sites 

based on previous scouting on surface on boat with the crew and even underwater 

with rovers, making crew aware about what is above the surface in order to 

assume what could be underwater

▪ Later NXT missions can be used as a platform to test new technologies and ops 

tools to "immerge more" the scientist at MCC into the crew environment and to 

better bring the scientist in MCC virtually closer to the crew

▪ Schedule an engineering week one week before NXT to let the core team test the 

assets and comms and scout the sites

▪ Once the mission starts, only the crew should get into the assets for the mission 

duration (except for first sun training runs with an experienced copilot)

❖ NASA core team should recertify on the assets and/or explore before 

crew arrival

❖ For the crew, only 1 day in MCC is required for ops awareness

❖ Crew should be the only explorer team underwater

• Nuytco

o Difficulty for Nuytco team to run simultaneous operations while attempting to troubleshoot 

various systems on two different assets

▪ Playbook view in the Nuytco trailer for real-time tracking helped with the pace

▪ NASA personnel were trained to help with simple Exosuit tasks 

o Recommendation: Provide a forum in which the Nuytco team and NASA team can provide 

realistic daily schedules based on repairs, adjustments and changes to the next day's 

timeline

• Need to analyze the metrics and correlate them to objectives

• NXT is not a one-for-one replacement for NEEMO (Aquarius)
Dive Support and Imagery Lessons Learned & Recommendations

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 49

• Dive Support

• Review dive plan and roles for the mission with NEEMO Dive Safety Board before the mission.

• Conduct a detailed dive team briefing on or before MD 01.

• Brief roles and responsibilities of Dive Supervisor with dive team before start of diving 

operations.

• Conduct a detailed dive briefing with the chase boat and dive boat crew before each 

excursion.

• Furnish each diver with safety sausages, lights, and compasses. 

• Provide all of the appropriate and properly sized equipment for divers (e.g., gloves) or make 

sure divers bring their personal gear.

• Ensure each diver is comfortable with open water diving where there are no references. 

• Ensure divers are comfortable in low visibility conditions and have adequate skill with a 

compass.

• Ensure divers are comfortable with deep and cold dives when called upon to conduct those. 

• Train dive team on use of a compass and underwater navigation

• Train dive team on live boat operations

• Imagery

• Topside imagery was great!

• Underwater imagery turned out good – need to plan around that many of those are taken in 

deeper colder water
Mission Plan/Timeline Lessons Learned & Recommendations

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 50

• No mission plan or timeline was sent to the operators before the mission.

• Timeline evolved day-by-day, with crew sometimes not knowing their role until the morning.

• Ensure the mission timeline is focused on the NASA objectives.

o Review preliminary plan/timeline with the team before the mission.

o Review the detailed timeline with the crew at the evening big team meeting (or 

before). 

• Core team meetings

o Continue with the practice of a daily core team meeting, and have that meeting 

timelined in Playbook. 

o Include key personnel in the core team meetings – MMT, EVA, EVA Tools, Playbook, 

Science
Lessons Learned & Recommendations: Exosuit

EVA-EXP-0072 This document does not contain any export control information (#20205009476) 51

• Multiple locations within the Exosuit cause discomfort or bruising after prolonged use.

o Problem: Reported from multiple users, various locations within the Exosuit caused 

bruises or soreness including: elbows, knees, forearms, bridge of the nose.

o Recommendation: Going forward supplying knee pads, elbow pads, forearm sweat 

bands, gloves and pads for the nose. These items should be added to a XX/CX pre-dive 

checklist for future use.

xEVA HUD

• Utilizing Lumus DK-52 displays as an xEVA HUD capability evaluation 

platform

• Objectives include evaluating xEVA con ops for incorporating an informatics 

HUD capability for suit data, pioneering tasks, and science tasks

• DK-52 provides the basis/backbone for the Navy’s DAVD system, which was 

tested in cooperation with the EVA Office during NEEMO 23

• One NASA/EVA-owned unit is currently at JSC for evaluation and one is at 

Nuytco for integration and testing with the Exosuit

xEVA Underwater Task Board

EC7 Preliminary Design Overview

• The goal of this project was to provide a challenging task in 

which the use of a heads-up display would be valuable.

• This board is being designed to be utilized in the NBL and at 

NEEMO NXT. 

• It is a pressure system that will be powered by a SCUBA tank.

• The frame (pictured to the left) will have a series of challenges 

mounted to it for the test subject to work through. If they 

complete tasks successfully, “victory bubbles” will be released.

• These challenges involve configuring valves in a proper 

orientation and order, reading gauges to verify proper 

pressure readings, pressing foot pedals to actuate linear 

pistons, and the ability to be reconfigured to provide different 

flow paths and order of operations. 

• It will be placed on a surface and weighed down with sand 

bags or weights for stability.

• It is being designed to be rugged to handle interactions with 

an Exosuit, surface supplied hard hat diver, or a spacesuit.

EVA task board designed to be used in various aquatic 

analogs, such as the NBL, NEEMO, and NXT

Will be used at NXT for Exosuit training and xEVA HUD 

evaluations

Design and build led by EC7/EVA Tools

EC7/Naids, XX/Coan, and XI/Graff will have 

responsibility of board during deployment

WHY: EVA-Specific Goals for Integrated Operational Testing

69

The primary goal for EVA is to inform the Exploration EVA

System Concept of Operations by exploring the

combination of Operations and Engineering with Science

for Exploration destinations in a mission-like environment

• Advance the future of the Exploration EVA System and 

operations

• Understand EVA capability needs and concepts of 

operations for a wide range of Exploration destinations 

being considered by NASA

• Assess the system and architectural interactions between 

Operations, Engineering, and Science 

• Determine and document closures to gaps in EVA 

capabilities and knowledge

• Develop and document concepts of operations for EVA at 

the Exploration destinations (EVA-EXP-0042)

• Realize the needs of EVA equipment and enable the 

development of concepts for design maturation on the 

road-to-flight 

EVA-EXP-0072 This document does not contain any export control information (#20205009476)
NEEMO Neoteric eXploration Technologies (NXT) as Presented to EISD

XEVA SYSTEM CON OPS & CAPABILITIES DEVELOPMENT

➢ Tools

• Development of a heads-up display (HUD) concept 

(e.g., HoloLens and DAVD) in an encumbered suit 

(Exosuit) for potential expansion into the xEMU

• Development of an IV Workstation and Support 

System needed for EVA and Science operations, 

especially at destinations with long signal/comm 

latencies

➢ Techniques

• Evaluation of planetary pioneering and science 

operations while conducting tasks with a restrictive 

suit in an extreme environment

• Development of integrated operations and 

capabilities between EVA and Science, with 

operations being directed by an MCC Science Team

➢ Technologies

• Evaluation of concepts for hands-free advanced 

informatics with real-time data that could be applied 

to future Exploration spacesuit systems (e.g., DAVD)

➢ Training

• Exploration operations training for personnel that 

don’t have extensive direct operational experience 

NEEMO NXT

▪ Concept currently in development for an add-on and eventual 

follow-on for NEEMO

▪ Focuses on Exploration operations development and training, xEVA 

informatics, xEVA con ops, and integration of science operations

▪ Offers a high intensity operationally challenging environment, with 

high workload, elevated stress, high bandwidth, time pressure, and 

unexpected external perturbations 

▪ Utilizes Nuytco Research Exosuit and DeepWorker submersibles

▪ Potential partner for spacesuit develop, especially for joints

▪ Submitted a response to the EVA Spacesuit RFI 

(#80JSC018EVASUIT) 

▪ Exosuit provides an analogous restrictive suit that requires similar 

effort for positioning and working in an EVA suit, along with a 

relatively large helmet volume at 1 ATM to evaluate off the shelf 

informatics hardware (e.g., DAVD, HoloLens, etc.)

▪ Provides operations training and experience for XA/EISD personnel 

(managers, engineers, scientists) without extensive ops experience, 

including flying as co-pilot with a crewmember/astronaut in a Dual 

DeepWorker sub

▪ Expands partnership with Navy for development of xEVA informatics

▪ READy FY19 plans include

▪ Terrain scouting and feasibility mission planning 

▪ Feasibility assessment of assets and core team training 

▪ Feasibility mission as a ‘test flight’ of the concept
