David Sandy is Managing Director of The Aerospace Corporation UK, where he works at the intersection of space technology, defence operations, and government decision making. He brings over three decades of operational military and UK government experience, including senior roles in the Ministry of Defence Space Directorate, where he helped shape UK defence space strategy, investment priorities, and long term capability planning. David specialises in translating complex technical and systems engineering conversations into clear options for senior operational and policy leaders. His work spans space domain awareness, resilient space architectures, and the end to end delivery of space capabilities, from early concept and mission design through to acquisition and operational integration. At SmallSat Europe, David will deliver a technical brief on DiskSats as a next generation smallsat architecture, focusing on how novel form factors, manufacturability, and system integration choices can translate into scalable, decision relevant capability for defence and national security users.
