Predicting the lifetime of an electric ion thruster is notoriously difficult. You have to account for the chamber wall effects, which are not present in space environments. Researchers within several ...

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 ...

Demand for electric propulsion is growing for space applications and the proposed technological solutions are evolving fast. Gridded Ion Technology allows a more efficient management of Xe, providing ...

Rocket propulsion technology has progressed leaps and bounds since the first weaponized rockets of the Chinese and Mongolian empires. They were nothing more than rocket-powered arrows and spears but ...

Spacecraft rocket engines come in a variety of forms and use a variety of fuels, but most rely on chemical reactions to blast propellants out of a nozzle, with the reaction force driving the ...

Most people are probably familiar with iodine through its role as a disinfectant. But if you stayed awake through high school chemistry, then you may have seen a demonstration where powdered iodine ...
