Scientific paper

ORFEUS (Orbital and Retrievable Far and Extreme Ultraviolet Spectrometer) is the largest and most powerful astronomic telescope ever developed for the investigation of extraterrestrial sources of ultraviolet light such as white dwarfs, intergalactic hydrogen clouds, etc. In September 1989, the C/D phase of the ORFEUS telescope was launched. The present report supplies a description of the system, project management, and names areas of problems. For example, the thermal verification of the active and passive thermal hardware under realistic environmental conditions (vacuum, solar simulation) was carried out in a large thermal vacuum chamber (diameter 6 m). The general reusability of ORFEUS without any major modifications results in a high cost-efficiency for further scientific missions. Therefore, DARA and NASA have agreed to fly a second mission extended to 10-14 days using the same configuration in late 1995.
