Swarms of autonomously maneuvering satellites promise to make space operations far more efficient. But they also pose collision risks.

Through the Starling mission, NASA and SpaceX will begin testing strategies for preventing autonomous satellites from crashing into each other.

NASA originally planned to send the Starling mission into an orbital altitude of 555 kilometers. Because SpaceX Starlink broadband satellites operate in that orbit, the space agency’s Conjunction Assessment Risk Analysis (CARA) group advised Starling mission managers to send the four Starling cubesats 10 kilometers higher.

“Realizing that these two constellations are close to each other gave us an opportunity to look at how we will deal with space traffic management in the future, when there are even more spacecraft in low Earth orbit,” said Howard Cannon, NASA Starling project manager at the NASA Ames Research Center. “How can we avoid collisions given the number of spacecraft that will be up there?”

NASA is preparing to launch Starling, its first satellite swarm. Instead of communicating directly with the four Starling cubesats, mission operators will send instructions to the swarm as a single entity.

If successful, “swarms have a potential to revolutionize the way we do science,” said Howard Cannon, NASA Starling project manager at the NASA Ames Research Center. “Instead of having one monolithic spacecraft that you are dependent on operating properly, you can have multiple smaller spacecraft that are less expensive.”
