The Extreme Ultraviolet Explorer (EUVE) was a space telescope for ultraviolet astronomy, launched on June 7, 1992. With instruments for ultraviolet (UV) radiation between wavelengths of 7 and 76 nm, the EUVE was the first satellite mission especially for the short-wave ultraviolet range. The satellite compiled an all-sky survey of 801 astronomical targets before being decommissioned on January 31, 2001. It re-entered the atmosphere on January 30, 2002.[3]

Mission goals

The goals of the mission included several different areas of observation using the extreme ultraviolet (EUV) range of frequencies:

  • To make an all-sky survey in the extreme ultraviolet band
  • To make a deep survey in the EUV range on two separate bandpasses
  • To make spectroscopic observations of targets found by other missions
  • To observe EUV sources such as hot white dwarfs and coronal stars
  • To study the composition of the interstellar medium using EUV spectroscopy
  • To determine whether it would be beneficial to create another, more sensitive EUV telescope

Payload instruments

NASA describe these:[4]

  • 2 Wolter-Schwarzschild Type I grazing incidence mirror, each with an imaging microchannel plate (MCP detector)(Scanner A & B) FOV ~5° diameter; two passbands 44-220 Å 140-360 Å
  • 1 Wolter-Schwarzschild Type II grazing incidence mirror, with an imaging microchannel plate (MCP detector) FOV ~4° diameter; two passbands 520-750 Å 400-600 Å
  • 1 Wolter-Schwarzschild Type II grazing incidence mirror Deep Survey/Spectrometer Telescope. The light is split, with half of the light fed to:
    • An imaging Deep Survey MCP detector [and the other half to ]
    • Three Spectrometers which are each combinations of a grating and MCP detector: SW (70-190 Å) MW (140-380 Å) LW (280-760 Å).
