After setting foot on the Moon, the next destination for humankind is Mars, which presents a whole new set of challenges in speedy, long-distance space travel.

    It’s a Rotating Detonation Rocket Engine"

    What makes the RDRE so revolutionary is that it makes use of a sustained detonation circling around a ring-shaped channel, fed by a mix of fuel and oxygen which is ignited by each passing explosion.
    Crucially, the RDRE uses less propellant fuel than conventional rocket engines, and is simpler in terms of its machinery and mechanisms. That means going into space becomes cheaper, and traveling further distances becomes possible.

      NASA invented a space ship powered by a rotary engine? Noice, at least until the apex seals give out, but they should be good for 80k at least.

          The wankel and rdre aren’t really related, but they’re similar in that they’re both oddball engines with surprising performance.

          Of all of my near future rocket engine predictions, a working aerospike rdre was not on my list… I’m honestly very impressed!

        No, it’s just gas powered car that still needs tanks and has everyone knows a around trip back to anywhere requires gas. The “ECO” of space travel.

            We don’t have unlimited fuel, rockets cost too much fuel. It’s not even normal fuel either, it’s rare chemistry rocket technology that takes a while to develop.

              Alright so nobody’s going to stop launching rockets realistically, there’s too much potential in space to just ignore, rdre are a way to do the same with less.
