The International Ultraviolet Explorer satellite operates as an astronomical observatory to provide both high and low resolution UV spectra of sources other than the Sun. The spacecraft, its instrumentation and the ground control system are described. 

Present and Forthcoming UV Missions

Over the past 40 years, UV telescopes and spectrographs have improved by many orders of magnitude in some key parameters that govern their ability to perform useful observations. This article surveys

Atomic and molecular data for observations of the interstellar medium with the hubble space telescope

The high resolution spectrograph on HST, with resolving powers up to 94000 or 3.2 km s−1, is giving us a new look at interstellar absorption lines in the range 1090 to 3350 A. The high

A brief survey of normal and grazing incidence space telescope types is given. The optimization of telescope efficiency either by dedicated single, bi-layer or multilayer coatings is described. An

Performance Of The International Ultraviolet Explorer For Spectral Imaging

The International Ultraviolet Explorer (IUE) satellite is an astronomical observatory which has obtained more than 25,000 spectral images since its launch in January 1978. A 45 cm f/15 cassegrain

Observations of interstellar molecules with the International Ultraviolet Explorer

The ultraviolet spectra of 25 early-type stars have been obtained with the International Ultraviolet Explorer observatory. Bands of the 4th-positive system of interstellar C0 are seen towards 12 of

Extragalactic Work with IUE

The International Ultraviolet Explorer (IUE) is an 18 inch (45 cm) space telescope for ultraviolet spectrophotometry in geosynchronous orbit and is a joint project of the European Space Agency, the

Solar motion-based method of attitude recovery - Application to International Ultraviolet Explorer

The International Ultraviolet Explorer is a geosynchronous orbiting telescope launched by NASA January 26, 1978, and operated jointly by NASA and the European Space Agency. The spacecraft was built

Ultraviolet spectra of asteroids

Spectra over the range 2,100–3,200 Å have been obtained for the three largest asteroids—Ceres, Pallas and Vesta—using the International Ultraviolet Explorer (IUE) satellite1. These represent the

New Methods of Determining Spacecraft Attitude

A new method was developed which required pointing the spacecraft at the antisolar position, which utilizes IUE’s ability to track the sun with a solid state two-dimensional sun sensor and can now be completed in several hours.



IUE observations of Solar System objects

During the scientific commissioning phase of IUE several spectra were acquired from objects residing in the Solar System. The activities focused on testing numerous parameters which would indicate

IUE observations of the interstellar medium

Results from a preliminary study of interstellar absorption lines in the spectra of the three stars HD149757, HD93521 and HD153919, observed by the IUE during its commissioning phase are presented.
