Since the 1980s, the collaborative efforts by NASA, the European Space
Agency (ESA), and the Institute of Space and Astronuatical Science (ISAS)
of Japan have led to the conception of the International Solar-Terrestrial
Physics Science Initiative consisting of a set of solar-terrestrial
missions to be carred out during the 1990s and into the next century. This program combines resources and scientific communities on an international scale using a complement of several missions, along with complementary ground facilities and theoretical efforts, to obtain coordinated, simultaneous investigations of the Sun-Earth space environment over an extended period of time.

Primary Science Objectives |
The primary science objectives of the ISTP Science Initiative are as
follows:
|
Teamwork |
The ISTP Science Initiative uses simultaneous and closely coordinated
measurements from GEOTAIL, WIND, POLAR, SOHO and
Cluster. These measurements of the key regions of geospace will be
supplemented by data from Equatorial missions and ground-based
investigations. The Equatorial missions include: the Geosynchronous
Operational Environmental Spacecraft (
GOES) Program of the National Oceanic and Atmospheric Administration
(NOAA) and the Los Alamos National Laboratory (
LANL) spacecraft from the Department of Energy (DOE). The
ground-based investigations include:
These missions and investigations will provide a measurement network to determine the local state of several key magnetospheric regions. However, because the magnetosphere is a vast interactive system, a comprehensive understanding can be acheived only if local measurements can be related to large-scale structure observations. The integration of theory and modeling with satellite and ground-based observations completes the ISTP Science Initiative.
