Space is changing, and the number of actors operating in orbit is increasing. Meanwhile, the amount of data collected by satellites is increasing as well. This data-treasure is priceless, supporting human and robotic exploration of space, helping us to take care of our planet as well as to unveil the most distant secrets of the Universe. However, one of the main challenges of nowadays space activities is downloading data from space to Earth. IBM and KP Labs together with ESA is forecasting the future of technology by imagining space-based data centres.
