New Thruster Design Increases Efficiency for Future Spaceflight

Hall thrusters are used in earth-orbiting satellites and show promise to propel robotic spacecraft long distances, and the plasma ejected from the exhaust end of the thruster can deliver great speeds. Cylindrically-shaped Hall thrusters lend themselves to miniaturization and have a smaller surface-to-volume ratio that prevents erosion of the thruster channel. Investigators in China have developed a new design for CHTs that significantly increases thrust; they report their work in this week’s Physics of Plasmas.

'Perfect Liquid' Quark-Gluon Plasma Is the Most Vortical Fluid

NatureCover_QGPIllustration_Draft4.jpg

Particle collisions recreating the quark-gluon plasma (QGP) that filled the early universe reveal that droplets of this primordial soup swirl far faster than any other fluid. The new analysis from the Relativistic Heavy Ion Collider (RHIC) shows that the "vorticity" of the QGP surpasses the whirling fluid dynamics of super-cell tornado cores and Jupiter's Great Red Spot, and even beats out the fastest spin record held by nanodroplets of superfluid helium.
