The International Academy of Astronautics has named Marcel Nicolet, director of the Belgian National Center for Space Research, to receive its 1963 Daniel and Florence Guggenheim International Astronautics Award. Dr. Nicolet was honored for his achievements in aeronomy and planetary atmospheres and particularly for his prediction, which was subsequently confirmed, that a layer of helium is present in the upper atmosphere. He is former secretary general of the International Geophysical Year Special Committee and a member of the directorate of the Committee on Space Research.
