CURRENTLY OPERATING SOLAR-TERRESTRIAL MISSIONS:

Shown schematically on the left-hand side of Figure 1: Present Solar-Terrestrial Missions & First Order ILWS Missions. Many of these missions are expected to continue providing useful data in the future if the spacecraft and instruments continue to operate satisfactorily, the missions are still generating unique, valuable data, and if funding and tracking resources are available. Operation of some current missions may be downgraded or terminated because of degradation of their capabilities and/or to free up resources for new missions with more advanced and/or different scientific capabilities.

Figure 1 also shows schematically some of the international solar-terrestrial missions currently under development or in planning that are associated with the ILWS program.

SPACE MISSIONS WITH SOLAR TERRESTRIAL-INSTRUMENTATION:

The comprehensive listing of “Space Missions with Solar Terrestrial Instrumentation” provides brief summary information on a wide variety of solar-terrestrial and other space missions capable of acquiring solar-terrestrial physics data. Included in the listing are website addresses, agency or agencies with primary responsibility for the mission, goals of the mission, types of measurements, orbit, and status. The listing include currently operating missions, missions under development, and missions under study.

Figure 2: Space Missions with Solar-Terrestrial Instrumentation shows schematically the subset of these missions whose primary purpose is investigation of the solar-terrestrial environment and phenomena.

Figure 3: Space Missions with Solar-Terrestrial Instrumentation shows schematically the subset of these missions whose primary purpose is Earth science, planetary science, technology, or operations (communication and weather satellites).
