But new research suggests Mars’s weak magnetic field may have helped its atmosphere escape. The magnetic field of Mars is the magnetic field generated from Mars' interior. Today, Mars does not have a global magnetic field. However, Mars did power an early dynamo that produced a strong magnetic field 4 billion years ago, comparable to Earth's present surface field. After the early dynamo ceased, a … See more Satellite data The reconstruction of the Martian global crustal magnetism is mainly based on magnetic field measurements from the Mars Global Surveyor (MGS) magnetic field … See more Timeline of Martian dynamo The exact timing and duration of the Martian dynamo remain unknown, but there are several constraints from satellite observations and See more Paleomagnetic evidence Martian meteorites enable estimates of Mar's paleofield based on the thermal remanent … See more jaws of the lion scenario 5
