Technology Development Satellites

Developing new and improved technologies is essential for the continued evolution of all aspects of space infrastructure. Advancements in technology can provide new capabilities that did not previously exist, and improve the cost, reliability, performance, and other essential attributes of existing systems, be they launch vehicles, spacecraft, or ground systems. A sampling of some emerging technologies under active development demonstrates the range of possibilities for our future in space.

Ground Components

The United States currently operates the most capable SSA system, the Space Surveillance Network (SSN). The SSN is composed of stations based around the globe that use a combination of radar and optical information to track objects in orbit. The system has impressive abilities; it is able to detect objects the size of a basketball at an altitude of ## kilometers (## miles), and smaller objects closer to Earth.

Ground Networks

Ground stations serve as the links between Earth and space, tying together terrestrial and space infrastructure. They track satellites and spacecraft, as well as communicate with and control satellites, probes, crewed space vessels, and space stations.
