ESPA (EELV Secondary Payload Adapter)

The EELV Secondary Payload Adapter (ESPA) is a specialized device used in space launches to carry multiple small satellites, called secondary payloads, alongside a main satellite. It acts like a widely-spaced mounting platform, enabling several smaller spacecraft to share a single launch vehicle efficiently. This setup reduces costs and allows for more diverse missions. ESPA provides power, data connections, and protection for these secondary payloads during launch and space travel, making it a vital component for maximizing satellite deployment capabilities in space missions.
