Swarm tracks elusive ocean magnetism

The magnetic field is arguably one of the most mysterious features of our planet. ESA's Swarm mission is continually yielding more insight into how our protective shield is generated, how it behaves and how it is changing. ...

GRAPES-3 indicates a crack in Earth's magnetic shield

The GRAPES-3 muon telescope, the largest and most sensitive cosmic ray monitor recorded a burst of galactic cosmic rays that indicated a crack in the Earth's magnetic shield. The burst occurred when a giant cloud of plasma ...

NASA research gives new insights into how the moon got 'inked'

A powerful combination of observations and computer simulations is giving new clues to how the moon got its mysterious "tattoos"—swirling patterns of light and dark found at over a hundred locations across the lunar surface.

Magnetic shielding of ion beam thruster walls

Electric rocket engines known as Hall thrusters, which use a super high-velocity stream of ions to propel a spacecraft in space, have been used successfully onboard many missions for half a century. Erosion of the discharge ...

Electromagnetic radiation protection shields developed

The environment contains electromagnetic radiation and magnetic fields of natural and artificial origin. Even a short electromagnetic pulse is enough to knock any equipment out of operation. Candidate of Sciences (Physics ...
