Carmen Morales Durán Laboratorio de Astrofísica Espacial y Física Fundamental Instituto Nacional de Técnica Aeroespacial I studied Physics at Madrid University Complutense and did my PHD under the direction of Professor Willhem Becker from the Basel Observatory in Switzerland on the subject: Galactic structure by means of RGU and UBV photographic photometry. I have worked for five years at the Astronomy Department of the Madrid Complutense University as assistant professor of Astronomy and Instrumental Optics. In 1976 I moved to INTA into the National Commission for Space Research. There I started to work with ultraviolet data from the TD1 and IUE satellites. My research topics were then, and still are now, interstellar medium, interstellar reddening and blue straggler stars. In the late eighties I started a collaboration, with Willem Wamsteker and colleagues from Italy and the United States with the purpose of developing a satellite, called Santa María, to be launched in 1992 in the fifth centenary of the discovery of America. We didn't succeed, but in Spain this was the starting point for the development of a satellite, smaller and less sophisticated than Santa María but which was finally launched in 1997. The Spanish MINISAT was collecting and sending scientific data for 5 years. The Science Operations Centre, data processing, calibration and reduction was done at LAEFF for the ultraviolet instrument onboard MINISAT (EURD), for which I was the Principal Investigator. EURD consisted of two spectrographs observing simultaneously in the Far and Extreme ultraviolet (350-1100 A). The purpose of the instrument was to detect the emission from the hot interstellar medium. We observed only during eclipses in order to avoid the solar emission at these wavelengths. BUT due to the MINISAT orbit altitude of 587 km, our data were strongly contaminated by geocoronal lines of Hydrogen and Helium from the upper atmosphere. In the zones free of geocoronal lines we didn't get any line from the hot IM, only upper limits. At present I continue to study the interstellar reddening, mainly the 2200 A bump and the relation of total to selective extinction Rv which strongly influences interstellar reddening in the ultraviolet.
