EVA 23 Suit Water Intrusion

Recommendation R-44:

The ISS Program must establish a protocol whereby whenever conflicts arise between the MER and FCT concerning roles and responsibilities or one party’s performance during a particular event, the appropriate management from each side must meet to discuss the conflict and revise the roles and responsibilities or expectations accordingly.


Recommendation R-45:

The ISS Program should develop proficiency requirements for MER Managers by event they are certified to support, as well as on a time basis (e.g. annually) to maintain currency.


Recommendation R-46:

The ISS Program should provide training to the MER Managers to deepen their systems and vehicle knowledge to ensure proper subsystem and situational awareness during real-time operations.


Recommendation R-47:

The ISS Program should immediately modify the contractual clauses that may prevent the recommendations contained in this report from being implemented within the contractor community.


Recommendation R-48:

NASA real-time operations community should work with the JSC Human Factors team to assess areas where human factors processes can be better trained and implemented in operations and develop specific training to reduce the impact of human factors in future mishaps.


Recommendation R-49:

The ISS Program should commission an independent study team to identify options to ensure an ISS EVA capability through 2028 that trades improvements to the current single fault tolerant suit via options such as additional on-orbit diagnostics and preventative/corrective maintainability, redesign to separate water and vent loops, and/or implementation of an advanced suit.
