A Hack to Trick Automotive Radar

The technology can hide the approach of an existing car, create a phantom car where none exists, or even trick the radar into thinking a real car has quickly deviated from its actual course. Plus, it can do these things in the blink of an eye without having any prior knowledge about the specific settings.

Additive Manufacturing Subtracts from Rocket Build Time

Additive manufacturing is allowing NASA to deliver payload services and launch services at a better price point.
