MAGNETOMETER SURVEYS IN MINERAL EXPLORATION Magnetometer surveys have been used for many years as a reliable and well-established first step in mineral exploration, says Burns in a phone interview. A magnetometer is a passive sensor that measures variations in the Earth’s magnetic field. Depending on data quality, the recorded results can provide a picture of what lies beneath the surface. While we often hear terms like LiDAR, photogrammetry, and thermal imaging in connection with drone missions

Go inside a JPL clean room to see how we test the magnetometer on NASA's Europa Clipper Mission, which will help us answer the question, "Does Jupiter's moon Europa have an ocean?" 🤓 Magnetometer = a device that measures the strength of a magnetic field.
