HOPKINS ULTRAVIOLET BACKGROUND EXPLORER

ABSTRACT. The Hopkins Ultraviolet Background Explorer (HUBE) is currently the NASA MIDEX Astrophysics
Alternate Mission, but HUBE has now also been proposed to NASA as a Small Explorer (SMEX). I show, through
simulations, the very high quality of astrophysically important data that can be expected from HUBE, should it be
implemented as a Small Explorer.
1. Introduction
In this volume, in a companion paper (Henry 1997a), I discuss the scientific value and interest of
the cosmic diffuse ultraviolet background radiation. In the present paper, I describe the capabilities
of a specific proposed complement of instruments (an imager, and two spectrometers) for
measuring the intensity and distribution of the ultraviolet background radiation. Together, these
three instruments form HUBE, the Hopkins Ultraviolet Background Explorer, which was selected
in April 1996 by NASA as the Astrophysics MIDEX Alternate Mission.
Selection as an Alternate Mission does not guarantee construction and launch of the
mission; indeed, that result could only occur should the primary mission fail in its definition study.
The primary mission, MAP, is under definition by scientists at Goddard Space Flight Center, and in
