Goldstone antenna damaged and out of service
The Goldstone antenna in California that is a major component in NASA’s Deep Space Network (DSN) that it uses to communicate with interplanetary spacecraft was damaged recently and is presently out of service, with no known date for when or even if it will be repaired.
NASA’s Jet Propulsion Laboratory confirmed Nov. 10 that the 70-meter antenna at the Deep Space Network (DSN) site in Goldstone, California, has been offline since Sept. 16, with no timetable for its return to service. “On Sept. 16, NASA’s large 70-meter radio frequency antenna at its Goldstone Deep Space Communications Complex near Barstow, California, over-rotated, causing stress on the cabling and piping in the center of the structure,” JPL said in a statement to SpaceNews. “Hoses from the antenna’s fire suppression system also were damaged, resulting in flooding that was quickly mitigated.” [emphasis mine]
This statement suggests that as workers were changing the antenna’s orientation, it was moved too far in one direction, beyond the normal limits of that piping and cabling. The immediate question that the JPL statement avoids is this: What caused the antenna to “over-rotate”? Did something fail to stop it from going too far? Or was this an example of simple human error, whereby the person rotating the antenna failed to pay attention and allowed the antenna to exceed its limits?
Either way, the loss of this antenna not only poses a serious limitation in getting data back from the various unmanned probes at Mars, Jupiter, and elsewhere, it is also a problem for the upcoming Artemis-2 mission in the spring of ’26, which will rely on the Deep Space Network to communicate with the astronauts on Orion as it goes to and from the Moon. The network’s other two antennas in Spain and Australia can pick up the slack, but the system will have less redundancy, and more important, other missions will likely have to delay communications in order to give Artemis priority.
