The IMAGE mission was conceived to answer outstanding scientific questions
regarding the response of the Earth's magnetosphere to global solar wind
forcing. Image was to have been launched into a 7 Re X 1000 km orbit on
March 25, 2000. Three of the instruments on IMAGE are dedicated to energetic
neutral atom (ENA). The Medium Energy Neutral Atom (MENA) Imager is a finite
width slit camera designed to image atoms in the energy range from 1 keV to
30 keV. We will present initial results from IMAGE, with emphasis on
observations of the MENA imager. We will describe the instrument, show
examples of calibration results, and show examples of data obtained early in
the orbital mission. We will discuss the significance of the ENA imaging
technique and specific applications of the technique to topics in
magnetospheric physics.
