Starting in the early 1960s, spacecraft-borne plasma wave instruments revealed that space is filled with an astonishing
variety of radio and plasma wave sounds, which have come to be called "sounds of space." For over forty years these sounds
have been collected and played to a wide variety of audiences, often as the result of press conferences or press releases
involving various NASA projects for which the University of Iowa has provided plasma wave instruments. This activity has led
to many interviews on local and national radio programs, and occasionally on programs haviang world-wide coverage, such as
the BBC. As a result of this media coverage, we have been approached many times by composers requesting copies of our space
sounds for use in their various projects, many of which involve electronic synthesis of music. One of these collaborations
led to "Sun Rings," which is a musical event produced by the Kronos Quartet that has played to large audiences all over the
world. With the availability of modern computer graphic techniques we have recently been attempting to integrate some of
these sound of space into an educational audio/video web site that illustrates the scientific principles involved in the
origin of space plasma waves. Typically I try to emphasize that a substantial gas pressure exists everywhere in space in the
form of an ionized gas called a plasma, and that this plasma can lead to a wide variety of wave phenomenon. Examples of some
of this audio/video material will be presented.
