A CubeSat is a type of miniature satellite that is made up of standardized units, typically measuring 10x10x10 centimeters per unit. These small satellites are often used for scientific research, technology demonstration, and educational purposes. Their compact size and modular design allow for easier and more cost-effective launches into space. CubeSats are usually launched as secondary payloads on larger rockets, which helps reduce costs. They can carry various instruments for tasks such as Earth observation, space weather monitoring, and communication. Many universities and organizations, including NASA and the European Space Agency, have developed CubeSat programs to promote innovation in space technology.
