Interstellar comet 3I/ATLAS recently showed a ‘complex jet structure’ that has once again brought it into the spotlight, as captured by well-known comet observers M. Jäger, G. Rhemann, and E. Prosperi ...

Engineers at NASA's Jet Propulsion Laboratory in Southern California have revived a set of thrusters aboard the Voyager 1 spacecraft that had been considered inoperable since 2004. Fixing the ...

One of the great things about technology nowadays is how quickly an idea can get out there and take off. That’s because concepts are now able to get the funding they need in order to get their ...

A new plasma thruster could scale up to compete with traditional jet engines. The plasma is magnified by high-intensity microwaves and pressurized air. Researchers had to invent a way to measure the 1 ...

Assuming we hand-wave all of the scaling questions (!!), what this really looks like is a step towards real electrically-power airplanes. If I read this correctly, this system is considerably more ...
