NASA Goddard Space Flight Center

97 satellites in orbit, 33 operating.

The count is the catalogue’s as of Nov 8, 2026, 4:17 PM; whether a satellite is operating is as Orbinauts writes it where it has written when the satellite’s mission ended, and otherwise as Jonathan McDowell’s general catalogue believes it, licensed CC BY 4.0: GCAT

NASA Goddard Space Flight Center is how GCAT, Jonathan McDowell’s general catalogue (CC BY 4.0), names the organisation under the code GSFC, of United States of America. This page gathers the satellites it flies and those of every organisation under it, each row naming the organisation that flies it. It is part of National Aeronautics and Space Administration. See every satellite of National Aeronautics and Space Administration.
