Space, an earthly lever
Why explore? All figures and earthly applications below are aggregated exclusively from the missions tracked in this catalog: budgets, returns, spin-offs and discoveries documented mission by mission.

Technology transfers linked to 8 catalog mission(s): health, climate, materials, everyday life…
Key figures
Sum of public budgets reported for each spacecraft in the catalog (missions without explicit budget excluded from the total).
24 in operations, 7 in transit. All returns on this page come from this scope.
Science, technology, culture, economy and cooperation, one entry per fact attributed to a tracked mission.
Images, measurements, observations and samples listed on mission sheets.
Everyday spin-offs (23)
Technologies that moved from the space lab to daily life, each tied to a catalog mission. Sources: NASA Spinoff, ESA, documented programs.
Returns by mission (11)
Each catalog mission leaves a specific footprint: scientific, technological, cultural, economic or diplomatic.
