Focusing on the New Space economy and innovations in Earth observation, ESA’s fourth Φ-week kicks off on Monday 11 October 2021. Over the course of the week, the event, as a whole, will highlight how the New Space economy is developing in Europe alongside fierce competition worldwide, and how it can contribute to the EU Green Deal, Digital Europe Programme, Destination Earth initiative, UN Sustainable Development Goals and, in general, in context with the EU Space Strategy and the European space sector.
