539. The Extreme Ultraviolet Explorer Mission: Overview and Initial
The successful launch of the NASA Extreme Ultraviolet Explorer on June 7,
1992, is the culmination of nearly 30 years of effort at the University of
California at Berkeley to open up the field of extreme ultraviolet astronomy.
We present a brief introduction to this field and an overview of the satellite
instrumentation to provide the context for this set of articles discussing the
design and operation of the mission and the analysis of the data.

- Figure 1 (6kbyte gif) : The three basic modules
composing the Extreme Ultraviolet Explorer.
- Figure 2: Cross-sectional schematic of the two Wolter-Schwarzschild
survey telescopes: the shorter wavelength
(a) and the longer-wavelength (b)
- Figure 3 (12kbyte gif) : During the all-sky survey,
the spacecraft rotates about the spin
axis, letting the three survey telescopes sweep out a great circle on
the sky while the Deep Survey telescope images the ecliptic. As the
spin axis precesses the entire sky is imaged in six months, and a 2x18
degree swath along the ecliptic is deeply exposed.

variable line-space grating composing one of the three spectrometers.

escent coronal emission (light) and a flare (heavy) that took place
during the exposure.
