he Space Department has played a significant role in the development of space- based remote sensing instruments for scientific and military users. In this article we review the progress made here in the last 30 years as new instruments, designed to image the aurora, have been developed and flown. This effort is an integral part of the Space Department's emphasis on understanding the connection between the Sun and Earth and exploring the ways in which energy and mass are transferred from the Sun to the Earth. Auroral imaging is a key element of that effort since the aurora is a visible manifestation of the interaction between the Earth's magnetic field and the solar wind (the hot, ionized gas blown off from the Sun).
