Statement of Work (SOW) for Advanced Suit Glovebox System for Spacesuit Testing

Project Title: Development and Fabrication of an advanced glovebox system for testing and evaluation of advanced spacesuit materials.

Background: The overarching goal of the NASA’s Artemis Suit Material Project conducted by the Crew and Thermal System Division Advanced Suit Team, is to develop enabling technologies and potentially a turnkey solution for suit vendors for the outer shell fabric of a lunar suit environmental protection garment (EPG).

In order to thoroughly evaluate candidate technologies, simulation of the lunar surface conditions is necessary. One factor in particular is the effect of regolith on the integrity of spacesuit components. Evaluating state of the art protective outer shell fabrics rigorously enough for lunar exploration requires exposure to regolith “simulants”. A glovebox capable of simulating this environment allows for an efficient testbed for evaluating spacesuit components that incorporate these new outer shell fabrics.

Objective:

The Vendor will collaborate with NASA to develop an advanced glovebox system, based on the to meet the requirements of the Advanced Suit Materials project.

Period of Performance: No more than 20 months after ATP. The work will proceed over a defined schedule to ensure iterative feedback and final delivery within the required timeframe to align with NASA’s project schedule.

Travel: No travel expenses are required/included in this TO.

Scope of Work:

The following definitions differentiate between requirements and other statements.

Shall: This is the only verb used for the binding requirements, which must be implemented and verified.

Should/May: These verbs are used for stating goals, which must be addressed by the design, but not formally verified.

Will: This verb is used for stating facts or declaration of purpose.

Rationale is provided for most of the requirements. It is important to note that rationale is not binding and is only used to provide additional information or examples in order to the clarify intent of the requirement. In the event of an inconsistency between the requirement and the rationale, the requirement is binding and takes precedence.
