EVA Technology and Knowledge Gaps

EVA WorkshopFebruary 18-20, 2020Brian AlpertEVA Strategic Planning and Integration Office

EVA System Maturation Team

August 2013: NASA established System Maturation Teams with a capability-driven approach (vs program-driven)

Required SMTs to understand

each possible mission scenario, prioritize the needed technologies, and integrate with other SMTs

The EVA SMT does not actively work to identify gaps for missions beyond Mars as those are beyond the current conventional mission needs

The EVA SMT has implemented this for both EVA and Launch/Entry/Abort (LEA)Identify, champion and mature technology to support, enable, and enhance current and future missions viaCrowd sourcing (multiple methods) for novel conceptsSTTR, SBIR, STMD for hardware TRL advancementsAES, Programs, Projects for knowledge advancementsPrioritize investments given the current mission scopes and schedulesCommunicate plans and needs with Projects: EMU, xEMU, OCSS, AdvEVAStakeholders: HEOMD, ProgramsFunding sources (SBIR, STMD, AES, etc.)

Three types of gaps

Gap Definition: The comparison of actual performance with potential or desired performance for future systems capabilities.

Knowledge

:

Unknown data or mission parameters that will ultimately drive hardware requirements. Worked with the relevant architecture and requirements teams to resolve.

Development: At least one potential solution has been identified but additional work is required to ensure feasibility of the options (TRL 3-5)Technology: No known viable solution and new technology must be developed (TRL 0-3)In some cases, the existence of a hardware/technology gap cannot be determined until a preceding knowledge gap is answered3

What’s Different?

July 7, 2019: Gaps released as part of an ICES Paper

July 25, 2019:

Gaps

discussed by NASA/Kevin Wells at the 2019 EVA

WorkshopSince then…Artemis III took form and changed gap details and prioritiesFeedback from the 2019 EVA Workshop led to gap updatesThe xEMU project closed 23 EVA Gaps, with 22 more pending closure by 2024November/December 2019: The EVA Gap list was updated by the NASA community and put through export control

Motivation

NASA needs industry and academia help in identifying and closing gapsCommunicating our needs and priorities with

you…

gives

businesses an opportunity to direct IR&D towards NASA stated prioritiesgives academia an opportunity to direct research in areas

that are relevant to NASA stated prioritieshelps SBIR proposers understand more context on why the annual EVA subtopics are chosendecreases our likelihood of missing a gap6

Conclusion

The EVA SMT maintains awareness of changing program needs and priorities

Then

makes

updates to the gap list and priorities accordinglyThese priorities are then exercised when communicating and championing work fromCrowdsourcing, SBIR, STTR

JSC Technology Development and JSC/EA IRDSpace Act AgreementsSTMD/AES projectsGFE projectsThe annual EVA Workshop (and possibly ICES conference) will be used as a regular means of communicating this informationDay 2 of this EVA Workshop will include a collaborative forum to provide detailed review and discussion of EVA gaps, recently updated and published for this

workshop
