NASA staff accidentally broke a 230-foot-wide deep space antenna because they ran it on what investigators called "hero mode" — a culture that consistently called on them to step outside their training and improvise quick fixes. That approach helped keep the Deep Space Network's DSS-14 antenna online for years. But it also set the stage for a serious accident that caused up to $4.6 million in damage when the giant dish over-rotated and tore itself apart, according to a mishap investigation report. The mechanical failure happened on Sept. 16, 2025, at the Goldstone Deep Space Communications Complex near Barstow, California. The dish spun too far while tracking the Juno spacecraft orbiting Jupiter.

That mistake destroyed cabling, ruptured internal fire-suppression lines, and flooded the base structure with nearly 200,000 gallons of water. Mashable was among the first outlets to report on the accident. Investigators found that operators were trying to solve what looked to them like a safety-system glitch — and unknowingly disabled safeguards that prevent the antenna from moving past its limits. When they saw water, the operators tried to park the antenna — but that only caused further destruction."Personnel described themselves (and were described by personnel at other sites) as 'willing to do whatever it takes to keep the antenna running,'" the NASA report says. "Had GDSCC personnel acted with greater deliberation or shown more willingness to leave the antenna in a failed state at any point during the mishap, the undesired outcome likely would not have occurred."
