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 Spacecraft Magnetic Test Facility is located about 2 miles (3.2 km) east of the main campus of the Goddard Space Flight Center, in Building 310-20 on the north side of Good Luck Road. The building is a single-story structure, 60 feet (18 m) square, and is built entirely out of nonmagnetic materials.
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 spacecraft holds two orbiters, one for Europe and the other for Japan, that will circle the planet's poles. The spacecraft is named for the late Giuseppe (Bepi) Colombo, a 20th-century Italian mathematician who contributed to NASA's Mariner 10 mission to Mercury in the 1970s and, two decades later, to the Italian Space Agency's tethered ...
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 spacecraft has beamed back some of the best close-up photos ever of Mercury’s north pole. The European and Japanese robotic explorer swooped as close as 183 miles (295 kilometers) above ...
One study after the mission found a nonlinear fluxgate response when exposed to fields greater than 5000 mT. The applied field had to be transverse to the axis of the magnetometer. [12] The design was improved by creating a feedback relay over a spherical design. [13] This was the design used on later spacecraft, as the Ørsted satellite.
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 ...
