Welcome to the new NSSDC SPASE Registry. We now have a completely revised set of ways to query for information about the SPASE resources for which NSSDC acts as a registry.
Observatory Query. This interface allows queries to our database of observatories, most of which are orbital or sub-orbital spacecraft, but a few of which are ground observatories.
Instrument Query. This interface allows queries for information about scientific instruments that flew on-board various space missions.
Person Query. This interface allows queries for people that are tracked by NSSDC, primarily those that have been involved with space missions.
