In the next five years we are expecting to see 20,000 satellites launched into earth orbit. The seminar addresses pros and cons of this planned expansion (we currently have 1,500 satellites in orbit) and the impact of “mega -constellations” on the delivery of low latency superfast broadband for the Internet of things and rural blackspots; access to deep space (both by telescope and satellite) and the risk of it all becoming unmanaged spacejunk.
