SSTL has established that microsatellites – the next class up from nanosatellite CubeSats, size-wise – can do serious business in space. SSTL is integrating the TechDemoSat mission, backed by the UK‘s Technology Strategy Board and South East England Development Agency as well as UKSA. Launching by early 2013, TDS is testing test novel UK technologies requiring more performance than a CubeSat can muster.
