NASA | MAVEN Magnetometer

Jared Espley, a space scientist, explains the use of magnetometers in studying planetary magnetospheres. He discusses Earth's magnetic field and contrasts it with Mars, where a compass behaves differently due to anomalies. The Maven mission aims to study Mars' climate evolution and the effects of solar wind on its atmosphere. Magnetometers on Maven are crucial for measuring Mars' magnetic field, requiring careful placement and calibration due to their sensitivity. The video highlights the importance of thorough testing before launching instruments into space.
