The United States needs satellites to function. We rely on them for everything from communications to navigation, and that reliance isn’t limited to the civilian sphere. As technology continues to advance, the need for constant communications and data transmission to anywhere on the globe grows alongside it, and the potential fallout from an attack on our satellite fleet increases in parallel.
Because there are over a thousand man-made satellites currently orbiting around our little blue dot, and more than half of them belong to the United States, simply keeping track of where they are has become a full-time job for the US Air Force. When you add the tens or hundreds of thousands of pieces of debris sharing our small orbital neighborhood with those satellites, the need for continued tracking becomes an even larger imperative: we have to keep our satellites out-of-the-way of uncontrollable debris to ensure they don’t suffer any damage. Because the United States currently relies on Russian rockets to get us into orbit, we don’t have the means by which to mount a repair mission like we once did with the Hubble. A damaged satellite will likely simply become just another piece of debris instead.
With that in mind, DARPA (Defense Advanced Research Projects Agency) created an Advanced Space Debris telescope, sometimes called a Space Surveillance Telescope, designed to use a wide-angle lens to track very faint objects in the sky such as our own satellites. According to DARPA, this telescope, which they recently transferred to the United States Air Force to be relocated to the Harold E. Holt Naval Communication Station in Western Australia, will make keeping track of our satellites and any potential threats posed by asteroids, comets or debris easier than ever.
“From a military perspective, any one of those objects could put satellites at risk,” Nina Armagno, the director of strategic plans, programs, requirements and analysis for Air Force Space Command, said. “That’s why this capability is so important to us in Air Force Space Command.”
