If you're wondering how a dead satellite can do that, you're not alone, because no one knows for sure. In fact, the on-board equipment is not even capable of transmitting a 30 nanosecond pulse.

The dedispersed burst. Total burst power at Nyquist resolution (points—lines to guide the eye only) after dedispersion and coherent addition over 19 antennas according to the nearfield fit.

NASA's experimental Relay 2 satellite had been dead in the sky since 1967 — until last summer, when it emitted a super-short and very powerful burst of energy out of nowhere. In an interview ...

A mysterious and powerful blast of radio waves detected last year, suspected to originate far beyond the Milky Way came from a long-dead NASA spacecraft in Earth's orbit.

After taking a closer look, however, the team realized that the only viable source for the burst was NASA’s dead Relay 2, a short-lived satellite that hasn’t been in operation since 1967.

Zombie satellite? Dead NASA orbiter surprisingly emits powerful radio pulse The satellite had remained silent for decades after launching in 1964. By Ariana Garcia, Assistant News Editor June 20, 2025 ...

Home > Science Why Did This Long-Dead NASA Satellite Emit a Random Burst of Energy? Relay 2 became inoperable nearly 60 years ago, but for a brief moment in 2024, it outshone the rest of the sky.

A team of astronomers and astrophysicists affiliated with several institutions in Australia has found that a mysterious fast radio burst (FRB) detected last year originated not from a distant ...
