Kivonatos ismertetés:
Even before the official dawn of the Space Age - that is, before the launch 
of the Sputnik and Explorer spacecraft in 1957-1958 - many investigators 
around the world were engaged in space physics research. Using sounding 
rockets to get to the fringes of outer space, early researchers made 
pioneering observations of the Sun and Earth's upper atmosphere. This talk 
will recount some of the earlier history of contributions to Sun-Earth 
("solar terrestrial") studies. A principal focus of the talk will be the 
modern studies of energetic particles and electromagnetic fields in Earth's 
cosmic neighborhood. From a rather personal perspective, my Laboratory for 
Atmospheric and Space Physics (LASP) has been playing an increasingly 
prominent role in forefront studies of Earth's "magnetosphere" and LASP 
researchers are using this core terrestrial knowledge to advance planetary 
and astrophysical understanding as well. Moreover, study and understanding 
of the space environment of Earth is absolutely essential for our knowledge 
of "space weather" which represents a major threat to our modern technological
society. The presentation will address all these aspects and will conclude 
with a look forward to future solar system programs and opportunities.
