NASA’s “Zombie” Satellites Spark Concerns & Intrigue – Could Deactivated Tech Pose a Threat?

Jakarta,Indonesia – June 25,2025 – A surge of activity from decades-old,presumed-dead satellites is captivating the space community and raising questions about potential risks. Researchers detected “strange emissions” on June 13, 2024, originating not from deep space, but from Earth’s orbit [[3]]. Thes signals are emanating from NASA’s Relay 1 and Relay 2 experimental dialog satellites, relics of the early space age.

A Blast From the Past

Relay 1, launched in 1962, holds the distinction of being the first satellite to broadcast television signals from the US to both Japan and Europe, notably carrying the first transmissions of president Kennedy’s assassination [[2]]. Relay 2 followed in 1964, but its operational lifespan was brief, ceasing regular function by September 1965, with its transponder falling silent by 1967.

The recent re-emergence of signals from these satellites has stunned scientists. The burst detected by the Australian Square Kilometer Array Pathfinder (ASKAP) has reignited interest in what are being dubbed “zombie satellites” [[2]].

What’s Causing the Resurgence?

While the exact cause remains under inquiry, researchers at curtin University in Australia theorize that the satellites may be accumulating electrostatic charges over time, eventually releasing them in bursts [[3]]. Similar electrostatic discharge (ESD) events were previously observed by the Arecibo telescope, though over longer durations.Beyond Relay: A Growing Phenomenon

This isn’t an isolated incident. Other “zombie satellites” have shown unexpected signs of life. Michio Kaku reports that another satellite, LES-5, scheduled to expire in 1972, continues to transmit radio signals, sparking speculation about a classified military purpose [[1]]. Even NASA’s Opportunity rover on Mars is considered a “zombie” asset, continuing to operate long after its mission end date.

Potential Risks & Future Implications

The reactivation of these dormant satellites isn’t merely a scientific curiosity. Experts warn that these “zombie” assets could potentially interfere with modern communications and even jam signals [[1]].

The phenomenon underscores the growing need for improved space debris monitoring and the development of strategies to mitigate risks posed by reactivated, defunct satellites. The ability to detect these signals, as demonstrated by ASKAP, is a crucial step in understanding and addressing this emerging challenge.
