# Science Mission Impact

> NASA science mission costs, tracked publications, and citations from The Planetary Society.

Data snapshot: 2026-11-03. Use the export manifest for the dataset version and file inventory.
Active Mission Window and Lifetime are distinct measurement scopes. Base mission and division URLs show the active window; append lifetime/ for lifetime measurements. Each view is available as static HTML.
CSV mission summaries include both scopes. Read the dictionary before comparing costs or aggregating publications: missing values differ from zero, and a publication can be associated with more than one mission.
