CubeSat are small standardized satellites typically flown as secondary and containerized payloads piggybacking on the launches of larger satellites. Their low entrance cost have been a revolution in opening access to space for a broad range of institutions. In this talk the basics of CubeSat standards, technology and development are going to be presented. The goal is to proliferate the knowledge of what it takes to successfully build, launch and operate a CubeSat within and beyond the hacker community.
