NASA officials sounded an alarm Tuesday about the agency’s Deep Space Network, a collection of antennas in California, Spain, and Australia used to maintain contact with missions scattered across the Solar System.

Everything from NASA’s Artemis missions to the Moon to the Voyager probes in interstellar space rely on the Deep Space Network (DSN) to receive commands and transmit data back to Earth. Suzanne Dodd, who oversees the DSN in her position at NASA’s Jet Propulsion Laboratory, likes to highlight the network’s importance by showing gorgeous images from missions like the James Webb Space Telescope and the Perseverance rover on Mars.

“All these images, and all these great visuals for the public, and all the science for the scientists come down through the Deep Space Network,” Dodd said Tuesday in a meeting of the NASA Advisory Council’s Science Committee.
