The International Ultraviolet Explorer (IUE) was an astronomical observatory satellite primarily designed to take ultraviolet spectra. The satellite was a collaborative project between NASA, the UK Science Research Council and the European Space Agency (ESA). The mission was first proposed in early 1964, by a group of scientists in the United Kingdom, and was launched on January 26, 1978 aboard a NASA Delta rocket. The mission lifetime was initially set for 3 years, but in the end it lasted almost 18 years, with the satellite being shut down in 1996. The switch-off occurred for financial reasons, while the telescope was still functioning at near original efficiency.

abstract
  • El International Ultraviolet Explorer (IUE) fue un observatorio espacial diseñado para el estudio de la radiación ultravioleta. El satélite fue un proyecto de colaboración entre la NASA, el Science Research Council del Reino Unido y la Agencia Espacial Europea (ESA). El IUE fue propuesto por primera vez en 1964 por un grupo de científicos en el Reino Unido, pero no fue lanzado hasta el 26 de enero de 1978, a bordo de un cohete Delta de la NASA. Se le supuso un tiempo de vida mínimo de tres años, pero las expectativas se vieron desbordadas ya que finalmente, fue desconectado el 30 de diciembre de 1996, durando casi seis veces más de lo previsto. Fue el primer observatorio espacial operado en tiempo real por astrónomos que visitaron las estaciones de seguimiento en Estados Unidos y Europa. Se realizaron unas 104.000 observaciones, incluyendo planetas, cometas, estrellas, polvo interestelar, supernovas, auroras planetarias, galaxias, y quasars
  • The International Ultraviolet Explorer (IUE) was an astronomical observatory satellite primarily designed to take ultraviolet spectra.

The switch-off occurred for financial reasons, while the telescope was still functioning at near original efficiency. It was the first space observatory to be operated in real time by astronomers who visited the groundstations in the United States and Europe. Astronomers made over 104,000 observations using the IUE, of objects ranging from solar system bodies to distant quasars. Among the significant scientific results from IUE data were the first large scale studies of stellar winds, accurate measurements of the way interstellar dust absorbs light, and measurements of the supernova SN1987A which showed that it defied stellar evolution theories as they then stood. When the mission ended, it was considered the most successful astronomical satellite ever.
