One of the weirdest modern things to me is this obsession with generations. Maybe I haven't read the right stuff, but you pick up a 19th or 18th century book and they talk about the past, or conflict in families between old and young, but never this weird cohort-antagonism thing?

Could be it's random culture shit, but maybe it's because people have fewer kids, so they don't span generations? Or maybe tech acceleration means cohorts have more differences that are real?

@ZachWeinersmith I thinks it's marketing and media. The financial powers that be like us being in neat little boxes they can market too. And the media likes people being in nice little boxes so they have someone to blame. Put them both together and we end up with a culture that forces the imaginary importance of generational cohorts on us non stop until people start to belive the importance is real.

@arstechnica I'm torn between liking Starliner a lot but also hating Boeing as a company. Kind of like how I like Crew dragon and the idea of Starship, but SpaceX has been so soured for me I can't enjoy anything they do fully.

@nyrath the closest I feel we could get is a photon drive. But a Black body photon drive has terrible thrust, and an antimatter photon drive uses propellant. Only options I can see for a true propellantless drive is swimming in spacetime or creating gravitational gradients. But creating gravitational gradients that would result in falling forward is firmly in the "and then a miracle happens" portion of the equation.

Working on the space shooter taught me some new tricks with particle effects. So I quickly updated the antimatter engine plume in Cosmic Ocean. It looks and behaves a lot better.

Whenever I see "there is a planet in the habitable zone, but it's a gas giant" I always think gas giants can have rocky moons so it's still a viable candidate for habitability.

Finding a gas giant isn't a downer. I would even go so far as to say a large gas giant in the habitable zone potentially increases the possibilities of a habitable world. Even accounting for radiation belts. The number of moons they can have ups the dice rolls.

Aaron_DeVries,
@Aaron_DeVries@mastodon.social avatar

@isaackuo Exactly, ice shell moons are probably very common as well. The most common life in the galaxy could very well be subsurface life living in oceans of ice moons undergoing tidal heating. For more Terran centric life it also still stands. A large rocky moon could orbit far away from its gas giant outside of its radiation belt and do just fine with its own magnetic feild. Exo moons give us multiple chances per orbit position instead of a single rocky planet.

From what I understand (and I might be wrong here) the thrust produced by a magnetoplasmadynamic thruster is dependent on energy input. So if you built a rocket with an air breathing MPD thruster, and high capacity batteries that dump tons of energy into it over a short time. Would it have enough thrust to take off?

I just realized something. In the book I wrote (and still need to get third party edited) the main character uses a portable MRI sleeve a couple of times. I glossed over how it worked, but if LK-99 proves to be real, that technological oversight won't matter as much.

If the Titan Mare Explorer was selected, funded, and launched in 2016, it would have landed on Titan last year.

Been thinking about a lithium saltwater rocket. So far I'm at spraying the lithium deuteride water mix into a beryllium graphite engine core, where D+T powerd neutron sources direct multiple neutron beams down the core until they focuse to a point in the fuel spray. I'm just at fission right now. Maybe a magnetic nozzle could compress the D T water plasma to induce fusion? I'm not 100% how controllable it could be with magnetic fields.

Navigation system update! Instead of using a fixed point to calculate coordinates, it now uses the ship as the center point. So the coordinates and target indicator update in real time. Navigation is similar to what is used in Star Trek funny enough.

I'm thinking about the feasibility of building a small scale unscrewed stuhlinger umbrella ship. But replacing the reactor with a solar concentrator to heat silicon oil to run a generator. And replace the cesium grid ion drive with something more modern. Then send it to Venus from Earth orbit.

It wouldn't be the best or most efficient Venus spacecraft, but it would win major aesthetic points for being really cool.

I like the idea of iodine ion thrusters. The trouble with iodine reacting with everything is a bit of a headache. But when built according iodine ion thrusters are neat.

Funny enough, I basically live in a #15MinuteCity layout right now. And it's just convenient. Stores shops dental pharmacies, bars, a library. All withing walking distance.

Conspiracy theorists are really upset about this concept. But I enjoy taking 3 minutes to get groceries.

My 2 biggest take aways regarding the space gun in "Things to Come"

In the film the first crewed lunar mission took place 68 years later than it did in reality, so we won.

And the gun has a giant iron sight like a firearm. Which is funny and pointless.

Imagine being an alien en rout to invade Earth, then when your ship settles into orbit you detect dozens of nuclear detonation on the surface, followed shortly by your ship getting shredded by a swarm of tungsten cannonballs.

I'm still working on some updates for it, and as such it's still isn't perfect. But if you are interested in a simple Newtonian arcade space shooter, my game Flank Speed is available on Steam. Kind of a modern take on the classic game "Space War". With multiplayer in the works.

The printable parts of the rockets rotor recovery system are done. Will need to get the springs, screws, and probably a real bearing. It only needs to survive a flight, maybe 2.

I'm looking forward to making the full size rocket. The rotor recovery system will be much easier to make and likely based off a large RC helicopters rotor mount (which will also allow the rockets descent to be actively controlled).

the RTA-3 rocket is almost ready for printing. It will be the final RTA rocket, and test the rotor recovery system fully in flight.

It won't be the last Raven rocket, but the next rocket will be a new class, with new propulsion, and a new engineering goal. More on that later but i'm excited to reveal the new rocket class when the time is ready.

Flank Speed is now live on steam!

Multiplayer will be coming in a later update, as well as bug fixes that will undoubtedly be found, and reasonable game play suggestions I receive from players. It's just a simple arcade game but I worry about problems i've missed. Only time will tell now.
