Students at ETH Zurich have developed a multi-metal 3D printing process that can produce rocket engine components in days rather than the months required by traditional manufacturing. The technique, ...

When building a model rocket, it can be fun to get into the maths of it all—calculating the expected performance of your build, and then seeing how it measures up in the real world. To aid in that ...

Rotating detonation rocket engines work differently than traditional rockets to maximize thrust while using less fuel—an advantage that could help spacecraft explore farther in the solar system ...
