AETHER Data Modeling

NASA is seeking information to develop an acquisition strategy for modeling Extravehicular Activity (EVA) pre-breathe protocols to accurately predict Spaceflight Decompression Sickness (DCS) risk for lunar and Mars exploration missions. The goal is to create an operationally-feasible DCS risk prediction tool utilizing retrospective and prospective data, with a 6-month modeling period followed by 2 months for validation and 2 months for revision based on NASA feedback. The model must predict both Type I and Type II DCS, considering factors like cabin/suit pressures, physiological parameters, and pre-breathe durations, and must adhere to NASA-STD-7009 or an equivalent standard. NASA will provide a training dataset of 1500 trials and a separate dataset for validation, and proposers are encouraged to supplement with publicly available data such as that found at the CBDN Public Site. Deliverables include the modeling tool with all source code and supporting documentation. Responses should include a capabilities statement and are due by October 10, 2025.
