NASA interplanetary mission (NIM) dataset

The database consists of a survey of NASA Interplanetary Missions (NIMs) launched between May 1989 and October 2023. Mission data includes system-level attributes in support of advanced system-level modeling. The attributes include elements of the program, schedule, cost, and technical design. Cost silos include three inflation formats: Then$ representing realized expenses in the Year of recording, NASA’s New Start Inflation Index (NSII) adjusted expenses, and Personal Consumption Expenditures Price Index (PCEPI) adjusted expenses. Inflated values are adjusted to fiscal Year 2022 equivalent dollars with an index of 1.00 applied forward to adjust to 2023 and 2024 equivalent expenditures. The NIM database serves as a reference for future research and cost analytics in NASA's system-level analysis of the NIM., , # NASA interplanetary mission (NIM) dataset
