Astronomische Nederlandse Satelliet (ANS)

Astronomische Nederlandse Satelliet (ANS) was launched by a American Scout rocket from the Western Test Range, California, on August 30 1974 into a polar orbit. It was a collaborative effort between the Netherlands (NIVR) and USA (NASA). The University of Groningen and Utrecht (Netherlands) provided the Ultraviolet and the Soft X-ray experiments, while the American Science and Engineering company provided the hard X-ray experiment.
