Magnetic anomaly detection (MAD) is a critical technology used to identify and locate ferromagnetic objects, such as pipelines and unexploded ordnance, that may be hidden beneath the surface.

When these orbiters pass through the anomaly, it can cause satellites and spacecraft to experience short-circuits and malfunctions. That's because the reduced strength of Earth's magnetic field ...

For years, NASA has been studying a growing anomaly in Earth’s magnetic field that scientists liken to a “dent” or “pothole in space.” It is a giant region of lower magnetic intensity ...

A fairly well-known phenomenon called South Atlantic Anomaly (SAA) refers to the unusually weak magnetic field over South America and the southern Atlantic Ocean. And scientists acknowledge that ...

A magnetic observatory is being re-established on South Georgia to provide vital data on the 'South Atlantic Anomaly' as scientists monitor a possible reversal of the earth's magnetic field.

(These lineations, or anomalies, are different from those produced by the main magnetic field.) Joe Kirschvink of the California Institute of Technology and his colleagues later showed a similar ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

NASA is worried about the South Atlantic Anomaly (SAA). This anomaly affects Earth's magnetic field, which may pose risks to satellites and the International Space Station. The SAA is caused by ...
