The Aerospace Corporation (Aerospace) has been at the forefront of CubeSat technology and the miniaturization of satellites since before the CubeSat standard existed. Aerospace flew the world's first containerized satellite 20 years ago and has continued to push the state of the art in the 35 plus satellites that we have flown since then. Technologies and CubeSat missions pioneered at Aerospace have been adopted by many organizations in the rapidly growing CubeSat community, enabling Aerospace to have a leadership role in helping shape what is today’s CubeSat enterprise.
