This discovery has important implications for understanding the history and potential habitability of Mars. If the planet is protected by the magnetic field for a longer period of time, this means that life conditions can persist on it for a longer time.
Scientists used computer modeling and analysis of data on the magnetic field of Mars obtained using the spacecraft. They found that large impact craters on the surface of Mars, previously thought to be evidence of the early disappearance of the magnetic field, could be explained by other factors, such as a reversal of the magnetic field.
