This document is a NASA Shared Services Center Recommendation and Determination to Solicit from One Source form for the FY25 TICRA GRASP and ESTEAM Annual Technical Support and Maintenance Agreement. The document justifies sole sourcing for TICRA's GRASP and ESTEAM software, which are critical tools used by the JSC C&T analysis team to model antenna performance and electromagnetic interactions for human spaceflight programs. The estimated period of performance is from 7/1/2025 to 6/30/2026, with a total estimated cost not specified in the redacted document.

The justification emphasizes the unique characteristics of the software, including its extensive validation over several years through rigorous modeling activities, comprehensive antenna model libraries, and established simulation frameworks. Transitioning to a different vendor's software would compromise years of modeling and validation work, potentially causing significant technical risks such as extensive re-baselining, project timeline delays, increased costs, and potential reduction in technical modeling fidelity for human-rated spacecraft analysis.
