The 11th IAASS Conference “Managing Risk in Space”, organized in cooperation with the Japan Aerospace Exploration Agency (JAXA) is an invitation to reflect and exchange information on a number of space safety and sustainability topics of national and international interest. The conference is also a forum to nurture mutual understanding, trust, and the widest possible international cooperation in the responsible use of space. The once exclusive “club” of nations with autonomous space access capabilities is becoming crowded with fresh, and ambitious new entrants. New commercial spaceports are starting operations and others are being built. In the manned spaceflight arena, a commercial market is becoming reality with government use of commercial services for cargo and crew transportation to orbit and beyond. The international cooperation both civil and commercial is also gaining momentum.
