Magnetometers for non-space use evolved from the 19th to mid-20th centuries, and were first employed in spaceflight by Sputnik 3 in 1958. A main constraint on magnetometers in space is the availability of power and mass. Magnetometers fall into 3 major categories: the fluxgate type, search coil and the ionized vapor magnetometers.
Helium vector magnetometer (HVM) of the Pioneer 10 and 11 spacecraft. A magnetometer is a device that measures magnetic field or magnetic dipole moment.Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location.
The fluxgate magnetometer (FGM) is similar to previous instruments flown on spacecraft like the Voyagers, Magsat, Active Magnetospheric Particle Tracer Explorers, Mars Global Surveyor, etc. [10] This style of FGM uses twin wide-range, triaxial flux gate sensors mounted far away from the spacecraft body in which the magnetic flux is periodically switched (hence the ame flux-gate).

Kennedy Space Center The Europa Clipper Magnetometer ( ECM ) is a spacecraft magnetometer aboard the planned Europa Clipper mission. It will be used to precisely measure Europa 's magnetic field during consecutive fly-bys, allowing scientists to potentially confirm the existence of Europa's hypothesised subsurface ocean.
The magnetometer samples the magnetic field at a resolution of 0.016 nT at a frequency of 2.5 Hz. [69] On GOES-16, MAG consists of two sensors positioned on an 8 m (26 ft) deployable boom, separating the instruments from the main spacecraft body to reduce the influence of the satellite's own magnetic signature.
Michele Karen Dougherty CBE FRS FRAS [4] (born 1962) [2] [5] is a British space scientist who is professor of space physics at Imperial College London. [6] [7] She is leading unmanned exploratory missions to Saturn and Jupiter and is Principal Investigator for J-MAG – a magnetometer for the European Space Agency's Jupiter Icy Moons Explorer, launched in April 2023.
Swarm is a European Space Agency (ESA) mission to study the Earth's magnetic field.High-precision and high-resolution measurements of the strength, direction and variations of the Earth's magnetic field, complemented by precise navigation, accelerometer and electric field measurements, will provide data for modelling the geomagnetic field and its interaction with other physical aspects of the ...
Canadian Geospace Monitoring (CGSM) is a Canadian space science program that was initiated in 2005. CGSM is funded primarily by the Canadian Space Agency, and consists of networks of imagers, meridian scanning photometers, riometers, magnetometers, digital ionosondes, and High Frequency SuperDARN radars.
