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.

Mission goals

Extreme Ultraviolet Explorer wwwdaviddarlinginfoimagesEUVEjpg

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

Extreme Ultraviolet Explorer Extreme Ultraviolet Explorer Wikipdia

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).
