A team of engineers at Sandia National Laboratories have developed ways to rapidly evaluate new thermal protection materials ...

From the tragedy of the space shuttle Columbia disaster in 2003 to the now-routine return of commercial spacecraft, heat shields—formally called thermal protection systems—are critical for protecting ...

A controlled experiment has revealed how owls achieve their signature silent flight. Researchers found that the birds’ ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality. Advanced theories, seeking to unify general relativity and quantum mechanics, ...

Precise underwater navigation is critical for autonomous and remotely operated deep-sea vehicles, yet variations in seawater ...

US Army validates a new rainfield simulator with a hypersonic test, improving insight into how vehicles perform in extreme ...

NASA built an X-42A hydrogen-powered scramjet to reach speeds of Mach 9.6 for a brief moment in 2004. Therefore, this new unmanned aircraft would be more of an optimization and refitting of an ...
