CubeSats are a type of miniaturized satellite that is typically fastened to a standardized "cube" structure measuring 10x10x10 centimeters. They are used for a variety of purposes in space research and exploration, including Earth observation, climate monitoring, technology demonstration, and scientific research. CubeSats are often deployed in clusters or "constellations" to provide broader coverage and capabilities than a single satellite. These small satellites are relatively inexpensive to build and deploy compared to traditional larger satellites, allowing for more frequent and cost-effective access to space for a wider range of organizations and researchers. CubeSats are typically launched as secondary payloads aboard larger rocket missions, making them more accessible to a wider range of users.
