NASA scientists have just identified mysterious shapes flying above Earth. But don’t worry, this doesn’t mean aliens are about to strike. Using an imaging instrument called Global-scale Observations of the Limb and Disk (GOLD), the experts discovered strange X and C shapes, appearing at surprising times in the most surprising places. The researchers found that … Read more
New research shows that plasma fusion heat spreads more evenly in tokamak reactors, a milestone in the field of fusion energy. This suggests new ways to improve reactor efficiency and overall service life while reducing the chance of damage. The new findings from researchers at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory … Read more
This still image from a new simulation shows how plasma from the pedestal region is connected to the divertor plasma region via the so-called final confinement surface. The long and thin lobes fluctuate in time and space.

NASA, as always, is exploring the next generation of thrusters to enable increasingly ambitious space missions. One idea currently moving to Phase II of the NASA Innovative Advanced Concept (NIAC) program is a Pulsed Plasma Rocket (PPR). The PPR “uses a fission-based nuclear power system to rapidly induce a phase change in a fuel projectile … Read more
