A team of researchers used 3D particle simulations to model the acceleration of ions and electrons in a physical process called magnetic reconnection. The results could contribute to the understanding and forecasting of energetic particles released during magnetic reconnection, which could help protect space assets and advance space exploration.

The results could contribute to the understanding and forecasting of energetic particles released during magnetic reconnection, which could help protect space assets and advance space exploration.
"For the first time ever, we can use 3D simulations from fundamental physics principles to model the production of energetic ions and electrons in those magnetic explosions in space," said paper author Qile Zhang, of the Nuclear and Particle Physics, Astrophysics and Cosmology group at Los Alamos National Laboratory.
Magnetic reconnection can cause magnetic explosions, which result in events such as solar flares and geomagnetic storms near Earth; these explosions produce energetic-particle radiation that is harmful to spacecraft and humans. The research team discovered the underlying mechanisms controlling particle acceleration enabled by the 3D kink motions of plasmas - the collection of charged particles - and magnetic fields.

Carbon nanotubes could help electronics withstand outer space's harsh conditions
Washington DC (SPX) Oct 28, 2021
Space missions, such as NASA's Orion that will take astronauts to Mars, are pushing the limits of human exploration. But during their transit, spacecrafts encounter a continuous stream of damaging cosmic radiation, which can harm or even destroy onboard electronics. To extend future missions, researchers reporting in ACS Nano show that transistors and circuits with carbon nanotubes can be configured to maintain their electrical properties and memory after being bombarded by high amounts of radiation. ... read more
