Our science teams have made many discoveries significantly changing the
direction of Sun-Earth Connection physics, among these are:
1. The deep magnetotail does not hold the key to magnetosphere dynamics.
The "action" appears to be much closer to Earth although we are still
working to determine exactly where and how.
2. Collisionless reconnection is "the" most important energy transfer
process between the solar wind and magnetosphere and is more widespread
than first appreciated.
3. The terrestrial plasma source mass quickly loads the outer
magnetosphere after solar events and thereby may be a catalyst or driver,
rather than a consequence, of magnetospheric dynamics.
4. Shock fronts in the solar wind can be so steeply angled that they reach
Earth before they are observed at L1. This is currently causing many
uncertainties in the reliable modeling of the geospace response.
5. Different phases of a single solar cycle produce widely varying solar
wind input conditions to the magnetosphere and, in turn, a widely varying
cycle of dynamic response within the magnetosphere.
The future resides with answering new science questions that have come
from these discoveries. We invite you to visit the home pages of each of
these missions to learn more.
