For the first time in the US, a rotating detonation rocket engine takes flight
Venus Aerospace has completed a short flight test of its rotating detonation rocket engine. The concept has been discussed academically for decades and has previously been tested in a handful of countries, but this is believed to be the first US-based flight test of the idea. The technology makes traversing the globe in under two hours possible. Venus still has a long way to go before it can provide highly efficient hypersonic commercial flight, but the flight test proves that such a future is at least possible.
