63 years ago, the ancestor of Starlink launched: the little-known story of Syncom 2

On July 26, 1963, NASA launched Syncom 2, an experimental satellite that would profoundly transform telecommunications.

When we talk about satellite communications, the name Starlink immediately comes to mind well before Syncom 2. However, long before SpaceX’s constellation and its thousands of low Earth orbit satellites, this small American mission paved the way.

Launched on July 26, 1963, from Cape Canaveral by a Delta B rocket, Syncom 2 is the first operational telecommunications satellite placed in a geosynchronous orbit. Unlike earlier satellites that quickly moved across the sky, it remained virtually above the same region of the globe. This feat allowed for almost permanent radio links between two distant points.

A few days after it became operational, Syncom 2 successfully transmitted voice communications and data between the United States and Africa. The device also served for television demonstrations and several military and civilian experiments, validating a concept that would revolutionize global telecommunications.

Can we therefore speak of the ancestor of Starlink? Yes, but with some nuance. The two systems rely on very different architectures. Syncom 2 operated at nearly 36,000 kilometers altitude in a geosynchronous orbit, while Starlink satellites orbit at around 550 kilometers in low orbit to reduce communication latency.

On the other hand, the historical link is undeniable. By demonstrating that a satellite could ensure reliable and continuous communications with a specific area of the Earth, Syncom 2 laid the foundation for the entire space telecommunications industry. Television satellites, international telephone networks, satellite internet connections, and, several decades later, constellations like Starlink are all part of this technological evolution.
