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.
The mission was to map the Earth's magnetic field, the satellite had two magnetometers. The scalar (Cesium vapor) and vector magnetometers gave Magsat a capability beyond that of any previous spacecraft. Extended by a telescoping boom, the magnetometers were distanced from the magnetic field created by the satellite and its electronics.
They are star trackers that take a picture of the sky, then compare those images to a catalog of star maps to allow the orientation to be determined. [6] Juno ' s magnetometers will measure Jupiter's magnetic field with extraordinary precision and give us a detailed picture of what the field looks like both around the planet and deep within, ...
The International Real-time Magnetic Observatory Network (INTERMAGNET) is a world-wide consortium of institutes operating ground-based magnetometers recording the absolute level of the Earth's time-varying magnetic field, [2] [3] [4] to an agreed set of standards. INTERMAGNET has its roots in discussions held at the Workshop on Magnetic ...
It was launched from Johnston Atoll on July 9, 1962, and was the largest nuclear test conducted in outer space, and one of five conducted by the US in space. A Thor rocket carrying a W49 thermonuclear warhead (designed at Los Alamos Scientific Laboratory ) and a Mk. 2 reentry vehicle was launched from Johnston Atoll in the Pacific Ocean, about ...
A map may prove that Marco Polo discovered America more than two centuries before Christopher Columbus. A sheepskin map, believed to be a copy of the 13th century Italian explorer's, may indicate ...

A daring deep sea search has found tiny pieces of a mysterious meteor that crashed to Earth in 2014. The ‘alien hunter of Harvard’ tells Bevan Hurley the discovery may be evidence of an ...
