WebStrong magnetic stripes with alternating polarity run roughly E-W in the southern hemisphere, concentric with the south pole. These magnetic anomalies are found in rocks dating from the first 500 million years in Mars’ history, indicating that an intrinsic magnetic field would have ceased to exist before the early Noachian. The magnetic ... 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 … See more Paleomagnetic evidence Martian meteorites enable estimates of Mar's paleofield based on the thermal remanent magnetization (or TRM) (i.e., the remanent magnetization acquired when the meteorite cooled below the Curie temperature in … See more
Web3 hours ago · A European spacecraft rocketed away Friday on a decadelong quest to explore Jupiter and three of its icy moons that could have buried oceans. The journey began with a morning liftoff by Europe's Ariane rocket from French Guiana in South America. It will take the robotic explorer, dubbed Juice, eight years to reach Jupiter, where it will scope … WebThe solar wind stripped away most of the Martian atmosphere in only a few hundred million years after the planet lost its magnetic field. This process was quick because the Sun rotated much faster in its youth, which made the solar wind more energetic.
