Space Solar Telescope - SST, ein gemeinsames chinesisch-deutsches Weltraumprojekt zur Erforschung der Sonne Abschlussbericht

The project proposal 'Space Solar Telescope - SST' originally was put forward by Prof. Guoxiang Ai of the Chinese Academy of Sciences. Since such a project can hardly be realized by one country alone, particularly a country without tradition in civilian space research, it is proposed to carry this project out within an international cooperation of Chinese and German scientists. The intent is to observe the solar atmosphere at very high resolution from the solar photosphere up to the outer corona. Even for observations in visible light it is mandatory to switch to space based observations since the turbulent atmosphere limits the resolution for ground based telescopes. Within the framework of this grant an assessment study was carried out by a joint Chinese-German team of scientists. This included an estimation of the cost for the necessary German contribution. The result of the study is that it appears feasible to carry this project out within the framework of such an international cooperation. The German side will have to offer some technological help; in return it is offered space on the satellite for three German instruments, a soft X-ray telescope, a white light coronograph, and a radio spectrometer. Thus the total payload is a well balanced instrument package that allows to observe the whole solar atmosphere from its base, the photosphere, to the beginning of interplanetary space. The cost for the German side was estimated to be a little over MDM 60, which is of the order of the cost for a small satellite project.
