What do scanning electron microscopes and satellites have in common? On the face of things, not much, but after seeing [Zachary Tong]’s latest video on liquid metal ion thrusters, we see that they ...

mileage on the engine increases. That wisdom does not hold true for NASA’s ion engine, whose odometer continues to spin to the delight of its owners. This little engine that could has more than made ...

CLEVELAND — A small robotic surveyor arrives to explore a near-Earth asteroid. Another robotic spacecraft is returning to Earth with a pristine comet surface sample. Meanwhile, a robotic explorer is ...

Space debris is a growing threat to satellites and missions, with over 14,000 pieces already cluttering low-Earth orbit. To address this, Kazunori Takahashi, a researcher at Tohoku University in Japan ...

Over 14,000 pieces of junk are clogging up low Earth orbit, but this number could be reduced by a new invention that involves a satellite using the plasma exhaust of its ion engine to knock dangerous ...

Ion sources and neutral beam injection (NBI) systems lie at the heart of modern plasma physics research, providing a controlled means to generate and manipulate charged particles for plasma heating ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...
