FLIGHT International, 16 January 1975 79 A PATTERN OF MOLNIYAS HELIOS A N D S Y M P H O N I E BULLETIN Europe's two most recent experimental spacecraft continue to function nearly perfectly. The German-US Helios flight has experienced only one minor difficulty, the antenna for experiment No 5, the plasma and radio wave investigation being conducted by the Universities of Iowa and Minneapolis, having failed to extend fully. As a result, although data arc being received it is proving difficult to assess their reliability. The Franco-German Symphonie, Europe's first communications satellite, is described by officials of main contractor MBB as working "110 per cent" perfectly. The first transmission of pictures relayed by the satellite between the two terminals at Raisting in West Germany and PleumeurBodou in France took place on December 30. They were found to have suffered no loss of quality whatever when compared with the originals. In the meantime, the second Symphonie flight model will have completed integration in eight weeks' time but a launch date has yet to be fixed. MBB is confident that the satellite will in fact be launched. The company says that the French and German Governments are "not averse" to the launch, although they assert that there are "other European interests" to be considered. The present system of Russian communication satellites, according to P. J. Perkins and G. E. Perry of Kettering Grammar School, consists of four pairs of active Molniya 1 and Molniya 2 satellites circling the Earth in orbital planes spaced at 90° intervals. The close proximity of each member of a pair can be seen from the table below which, based on data from the Goddard Space Flight Centre, gives the predicted times and longitudes of passage through the ascending node (the longitude at which a satellite, travelling north in its orbit, intersects the plane of the equator) for October 4 last year. The table also shows that the ascending nodes are situated close to 63°E, which gives the best pass over the Soviet Union. Since each Molniya has a 12hr orbit, the next pass takes place over North America. Only a part of this orbit, near apogee, is visible over the pole from the USSR.

Right ascension is the astronomer's way of expressing the longitude of stars and other celestial bodies relative to the fixed background of the sky. The orbital planes rotate at the rate of about \° a day so as to maintain stationary ground tracks over the Earth throughout the year, thus providing predictable communication coverage over Russia These show that on October 4 the operational Molniya 1 satellites were the 27th, 26th, 24th and 25th in the series, these having superseded the 22nd, 23rd, 19th and 21st respectively. In recent weeks the 26th Molniya 1 has been replaced by the 28th Molniya 1 which, together with the 8th Molniya 2, has been joined by the first Molniya 3. On December 21 the 11th Molniya 2 replaced the 7th Molniya 2.
