The state of the art of RSFQ logic shows that this technology is viable for different areas of application. In fact, we have seen a significant increase in the number of circuits developed over the past twenty years, and the performances achieved: speed, power consumption, integration density and also in terms of technology: new JJ, submicron technologies ... the space domain, this technology has not yet found its place and this despite the need for more and more important in terms of computing power. The generation of cold remains the main lock of this technology. In this article, we will list missions carrying cooled instruments that could integrate the logic of the RSFQ. We will then expose the scientific objectives and the space agencies concerned.
In this paper, we present a current situation of the cooled sensors in the space domain. Thus, we present an immediate image of the recent developments of the cooled technology, a discussion about the relevance of using cold sensors in the spatial domain and influence of the position of sensor in the satellite. To finish, we shall present an example of future mission. It will be about the space telescope James Webb. We shall expose then the scientific objectives, the concerned space agencies and the date of launch. We shall also give information onto the cooled sensors.
