pulse of all space activities as they develop. This is not just for technical reasons, but from the political and negotiating standpoints. The need for a realistic assessment and solution of the real problems which exist should preoccupy not only the big space Powers. Preventing the militarization of space and transforming it for wide peaceful purposes are very general concepts. So far, conditions have not been created which would allow a complex discussion of these questions. However, we can direct ourselves toward more modest goals. One of these would be to work out a round of measures for building mutual confidence. There has been a lot of talk about this, but not very much has been done so far. Let us try to direct the efforts of our experts in this direction. A second area could be working out a kind of data base on the launching of satellites and the collection and classification of technical data. For this purpose, it would be a good idea to establish a scientific centre whose work could be shared among scientists in different parts of the world. The more information and the more experiences and the more opportunity for comparisons, the more could be built to contribute to deeper and more widespread co-operation, putting into practice the idea that space is a value common to all humankind. At the same time, let us not forget what Aristotle said: "Everything that has already happened, can happen again". This planet could certainly not survive a chain of Chernobyls in space. The field in which most attention is focused and in which we have made most progress, although the ongoing talks might not indicate this, is the outlawing of chemical weapons. One of the most discussed questions is the problem of control. Systematic verification under the chemical weapons convention will only 
**Analysis**
The text discusses the importance of cooperation in space activities, with a focus on building mutual confidence, exchanging technical data, and preventing the militarization of space. It also touches on the topic of chemical weapons and the need for control and verification. The tone is more philosophical and diplomatic, with a focus on the common value of space for humanity.
