Stoke Space's Andromeda 2 engine is incredibly unique. It's a single engine which feeds 24 thrusters around an actively cooled heatshield allowing the second stage to reenter engines first. It's also designed to operate in both sea level and vacuum conditions.

the most incredibly designed rocket ever conceived. change my mind

The Art of Flight is a homage to 80s/90s arcade action shmups with a fresh twist on the genre. Pilot multiple ships at the same time to take on oncoming waves of enemies in this fast paced space shooter. Wishlist on Steam today!

Is it not a major flaw that 1 engine does everything? I seem to think this could be a problem…

Having 1 engine on the second stage is very common. Falcon 9 only has one engine on the second stage and it's the world's most reliable rocket.

I CANT WAIT FOR THIS ROCKET TO BE DONE

Fascinating! Hope it gets a chance to do a flight test.

How protected does a camera have to be to withstand that much heat? 😮

More than the one in this video was lol.

Dang!

Build this! Based on @PERRY_RHODAN

If looks count for anything, it's a winner.

@SpaceHaxx this?

nozels would be better word to describe

I agree but Stoke calls them thrusters so I'll do the same.

That poor camera…

I don't understand. This is an engine? It looks like a freaking space ship from the movies. Pretty cool looking.

The Cameraman made it... YEEEHAAA!! SEE! Proof once more... 📸🧍‍♂️🛟🧬

Can you turn individual thrusters on/off and/or aim them for directional/attitude control?

They can choose which ones to fire which is useful for stuff like landing the second stage on the moon. The thrusters can also be individually throttled and they use the differential thrust from that for attitude control.

Cool! Hope you get it flying soon. Have you considered doing something like the original SpaceX Hopper? Just enough to let you go up and come back down and then build from there.

They did a hop test with an earlier version of the engine in 2023.

Love it! Get some legs from @steveMmattison and see if you can touch the sky!

Wow

POV you're Paladin Danse

Aerospikish. Doing what Arca space couldn’t.

Love it. Put it on a 2000 ton booster, and we are off to Mars

Doesn’t matter what its configuration is love, if it doesn’t fly.

What’s the engineering trade off?

It's a shame it's not a SpaceX engine. Otherwise this post would be in everyone's feed.

I can't wait to see if this technique or the tiles end up winning the reentry wars.

I actually really want to see if this thing can fly. They do some pretty cool work, and it looks like it should work too. Would be awesome to have some very different designs working since everything is quite similar right now other than their fuel.

Its neat i wonder how the concept scales and what scale is optimal

Put a teacher on it and launch already

Crew Dragon was meant to have been capable of propulsive landings with something like this, but they could not work out how to stick landing legs through the heat shield. And NASA certification would have taken too long. So parachutes it was.

Do you know why Starship has so many engines? Redundancy.

@ckindel That's not unique is been done before, they also found out it was unsafe to do.

Bullish on stoke's design
