Famous futurologist Alvin Toffler observed trends in wealth creation in the postindustrial society: everywhere (globalization), nowhere (cyberspace), and out there (outer space). Space technologies are already becoming an integral part of modern society. Satellite navigation based on the global positioning system (GPS) has become the basis for precision time and accurate location used worldwide by cellular phones, electrical power networks, and banking. GPS supports just-in-time manufacturing and worldwide logistics chains through precise tracking and is becoming central to commercial aviation. Satellite-based remote sensing supports improved agricultural productivity through high-precision farming and accurate weather forecasts, and helps in crisis management and disaster situation assessment. What are the most urgent challenges in space of the 21st century? Which kind of threats do we face from the outer space? How can we exploit space for the good of all humanity? How are space scientists collaborating across the globe? The symposium will bring together leading scientists and visionaries to present a unique perspective on the role of space science in meeting some of the most important challenges of the modern world.
