NASA Successfully Tests Revolutionary Rocket That Could Get Us to Mars Faster

  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.

    Thank you I was running low on clicks.

    That sounds sick. I wonder which sci-fi author came up with this idea ~60 years ago.

      My bet’s on Heinlein.

      Maybe the Jetsons, or the turbine engines in Star Wars? If you squint hard enough, it comes close enough.

    So it’s truthfully Revolutionary, hark! A spinning engine

    So they invented the rocket powered wheel?

    • firecat@kbin.social ⁨10⁩ ⁨months⁩ ago

      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.

  Revolutionary

  I see what they did there.

  This is a fancy aerospike engine right? The rotating detinations gives it higher chamber pressure and therefore better ISP or something?

  I will look for the Scott Manley video on this later (I think it was him?)

  Anyone have the ISP of this experiment to compare to other engines?

    You know what gets even better ISP? NERVA

    Should be the rotating detonation engine.

    • Nighed@sffa.community ⁨10⁩ ⁨months⁩ ago

      Real engineering also did one (actually better than Scott’s I think)

    NASA plans to have a manned mission to Mars in the next 6 years.

    source
• Desistance@lemmy.world ⁨10⁩ ⁨months⁩ ago

  I heard that the destination is actually Venus because it’s closer and has oxygen in the upper atmosphere.

  source

  • SCB@lemmy.world ⁨10⁩ ⁨months⁩ ago

    Venus is significantly more hostile than Mars, so while we definitely want to do more with Venus, Luna and Mars are clear next-ups for manned landings.

    While all of Mars is hostile to human life, Venus is also incredibly hostile to equipment, and thus requires a different approach to even unmanned launches.

    Current maximum lifetime for any unmanned craft in the Venusian atmosphere (to say nothing if the ground) is only 2 hours.

      Venus is interesting. While the surface is extremely hostile, the upper atmosphere is maybe the most similar to Earth-like environment out there in the solar system. At about 50km up in the air, the air pressure is about 1 Earth atmosphere, and the ambient temperature is about 20C. A 80/20% nitrogen-oxygen gas mixture is buoyant too at that depth, so a balloon filled with breathable air will just float. A rupture won’t cause explosive decompression like it would on Mars either. In addition, the gravity one would experience is only very slightly less than that of Earth, and the large atmosphere also provides some shielding against radiation.

      Mars doesn’t have these perks. Mars is cold, really cold, with only 1/3rd of the gravity of Earth, has practically no radiation shielding, and any breach would cause explosive decompression and almost instant unconsciousness. On top of that, regular solar panels really don’t work that well on Mars because of the extra distance from the Sun, while solar panels would actually work better in the upper atmosphere of Venus.

      Isn’t that on the surface? I believe Venus’s upper atmosphere is a lot more welcoming.

    Theres oxygen on Venus like there’s argon on earth, it’s so miniscule it’s useless.

  I remember first hearing about the development of this back in the early 90s on Beyond 2000.

    2km is a measure of distance not speed…
