The Astronomische Nederlandse Satelliet (ANS) was the first major Dutch space project, a space telescope for ultraviolet astronomy and X-ray astronomy .
ANS was placed in low-Earth orbit on August 30, 1974 from Vandenberg Air Force Base with a scout missile . It re-entered the earth's atmosphere on June 14, 1977.
ANS was a joint project of the Dutch NIVR and the US NASA . The scientific instruments were:
- an ultraviolet telescope with a mirror diameter of 22 cm with a spectrophotometer for the wavelength range 150-330 nm , a development by the University of Groningen
- an experiment for the soft X-ray range (0.16–0.28 and 0.3–7 keV ), a development by the University of Utrecht
- an American experiment for the hard X-ray range (1-30 keV).
Among other things, ANS discovered X-ray emissions for the first time from the corona of a star other than the sun, the star Capella . X- ray bursts and X-ray flares from the variable stars UV Ceti and YZ CMi.
