“Currently, no concept for space activities is more debated than ‘responsive space’. Here we have a splendid example of ‘responsive space law’. This small booklet with just one hundred pages is an outstanding piece of work responding to specific use of space, which has just been conceived and is only slowly getting implemented: satellite (mega-)constellations.” (Kai-Uwe Schrogl, Zeitschrift für Luft- und Weltraumrecht ZLW, Vol. 69 (4), 2020)
