Etalonnage absolu du spectro-photomètre infrarouge spatial "IKS" destiné à l'observation de la Comète de Halley by Didier Harduin( Book )

1 edition published in 1983 in French and held by 2 WorldCat member libraries worldwide

En décembre 1984, deux sondes soviétiques s'envolent vers Vénus puis la comète de Halley, qu'elles survoleront en mars 1986. Elles emporteront en particulier un instrument destiné à mesurer la dimension et la température du noyau de la comète, ainsi que la composition des principaux constituants gazeux et solides de la coma interne. Le travail présenté dans ce mémoire concerne l'étalonnage de chacune des voies, photométrique et spectrométriques, de l'instrument. Après une justification de l'ensemble des mesures à effectuer avant l'envol, il est procédé à une description du dispositif expérimental choisi puis·réalisé. Enfin, les premiers résultats obtenus sont présentés

Racing the Moon’s Shadow with Concorde 001 by Pierre Léna( )

1 edition published in 2015 in English and held by 0 WorldCat member libraries worldwide

This is the unique story of  observing a total solar exlipse for no less than 74 consecutive minutes. On the summer morning of June 30, 1973, the Sun rises on the Canary Islands. But it is strangely indented by the Moon. The eclipse of the century has just begun. From the west, the lunar shadow rushes to the African coast at a velocity of over 2000 kilometers per hour. Astronomers on the ground will enjoy seven short minutes of total eclipse to study the solar corona - too short for Pierre Lena and seven scientists who board the Concorde 001 prototype, an extraordinary plane to become the first commercial supersonic aircraft. With André Turcat as chief pilot and a crew of five, at 17000 m altitude, the aircraft remains in the lunar shadow for 74 minutes, a record time of scientific observations not yet beaten and allowing for exceptional measurements. Science, technology, aviation and history combine in the story of a unique human adventure aboard a legendary aircraft, illustrated with a rich and original iconography. It reflects the wonderful domains that science and technology can open, and the passion in the professions they offer. A must read for every eclipse chaser and fan of true scientific adventures
