Sup /sci//tg/ here. I'd like to incorporate an Aldrin cycler in my rpg setting and also would like to keep it as hard sf as possible but also fun. Can you help me?For those not familiar with this, the term “Aldrin cycler” refers to that very special orbital trajectory Aldrin discovered. The term can also be used to describe a spacecraft traveling along that special orbital trajectory. The initial investment to build an Aldrin cycler (the spacecraft, I mean) would be really high. We’d probably want to build a rather large spacecraft for this, and once it’s built, maneuvering the thing into the proper trajectory would require a stupendous amount of fuel.However, once we’ve done all that, the cycler will cycle back and forth between Earth and Mars, over and over again, pretty much forever. Traveling to Mars would be a little like catching a train.

>>16541245Dude who fucking cares. It's fantasy, just have it warp to hyperspace or some other sci fi bullshit. This has nothing to do with this board. If you want an autist's fantasy go get an aerospace engineer drunk and record his bullshit.
>>16541245>Can you help me?With what? Are we supposed to recieve your "hard sci-fi" questions using your in-game telepathy?
>>16541245Do you honestly think Earth and Mars maintain the same relative positions from each other?
>>16541245I love the aldrin cycler concept but I'm not sure what you're asking for help with>>16541587If you have no idea what the fuck you're talking about then feel free to not post
>>16541587Unbelievable retard
>>16541602My bad, dude. I was thinking this specific alightment (i.e., return to E1 and M1) would take centuries or longer to occur, but it's more like every 5.14 years.That is very reasonable.
>>16541662Oh no worries man I'm just used to the various schizos here sorry for the aggression!!
>>16541245>a stupendous amount of fuelYou could theoretically use less fuel by redirecting asteroids and colliding them to form an asteroid with the right trajectory. You can then send a small autonomous spacecraft to mine that asteroid and construct your structure in-place.This would take a long time, and require a bunch of material rich asteroids with very eccentric orbits to minimize fuel.
>>16541729No, man.>Unbelievable retardwas right. I made assumptions and failed to do my homework. You were right to call me out. I learned something cool, and thank you for it.No homo.
>>16541576>>16541601I'd like to figure out the layout of the thing and the living conditions inside (gravity and life support systems and stuff)I'm also struggling with the map since it's supposedly an hollowed-out asteroid so what exactly would be north south east west up down fore and aft and whatever>>16541810I was thinking about a re-routed asteroid initially heading toward earth, so all the powers that be had to work together to avoid the collision and the whole thing ended in a free Aldrin cyclerhere are a few questionsif this thing is rotating to create artificial gravity on the inside what happens if you stand on the outside surface?you fly away in outer space?would it need a non-spinning outer layer?also would the gravity be lower the closer you are to the rotation axis?wouldn't all the humidity gather there?could it rain inside that thing?could you jump and take off from one side and fly or swim through the middle to reach the other side?could there be something like a central stationnary spheroid acting like a small sun or a surveillance satellite?
>>16541957https://en.m.wikipedia.org/wiki/O%27Neill_cylinderhttps://en.m.wikipedia.org/wiki/McKendree_cylinder>what exactly would be north south east west up down fore and aft and whatever Local convention. Make north-south eun along the axis of rotation. East-west is the curved direction. If the rotation axis lights half the interior at once, so that the interior surface rotates under it, you can use Earth convention (day/night). Up points toward the axis. Down points away.>would it need a non-spinning outer layerYou can have a non or counter spinning outer layer. Fix the central lighting axis to the outer layer so the half lit portion rotates with respect to the inner layer to give day/night cycles (and determine east-west).

>>16541245Have them already deflected an asteroid a few decades in the past. The deflection puts it onto an Earth-Mars cycler transfer trajectory. Minimal fuel use and you get a lot of mass there. That it's used for your raw materials.
>>16541245I think the Marathon games have these cyclers.

>>16541587He never said they do, retard.
>>16542511That still has to be one of the most insane rocket engine concepts I've seen that could be build with current/near future tech
