It’s still crazy to me that it’s easier to fling something out of the solar system along the plane of solar rotation, than it is to get something above the poles of the sun. I understand why that is mathematically and physically. Still doesn’t seem like it should work that way.

on a side note, it takes less fuel to transport stuff to the surface of mars, than to the surface of moon. the reason is because on mars you can aerobrake while on moon you have to spend fuel to decelerate.

I actually already knew that, thanks to KSP, but thanks for reminding me.

what if you designed your vehicle to explode safely on impact?
gandalf_der_12te@feddit.org 1 day ago
you mean a series of small controlled explosions? like a car engine?

probably because the sun is so massive, and the heat, gravitational, solar flares would likely make that difficult.

Apparently it’s more because of inertia and the rotational spin of The Sun affecting the entire solar system, than anything else. Which actually makes me wonder if Voager and Voyager II will have issues once they fully pass beyond the heliopause.
Apparently our star, and therefore the rest of the solar system, moves around the galactic disc in the direction of galactic spin, but it wobbles “up and down”, as well as possibly “left and right” as it orbits the galactic center every 225 million years, or so.
The reason that Voyager, Voyager II, and pretty much every single other probe we send outwards might have some issues once they pass the heliopause is that our solar system is a bit tilted compared to the galactic plane of rotation. They may encounter some background inertia that we didn’t account for.

you just inspired me to test this in ksp because i suck at that game

You may want to look at how we did the Ulysses probe, by using Jupiter as a gravitational slingshot at about 80° relative to the solar plane of rotation, or the Solar Orbiter probe that is set to use The Sun as its gravitation slingshot when it reaches perigee. Thereby using the least amount of fuel possible, and turbocharging the eventual later deployment of solar sails.

I mean those are really cool, but I gotta get past mun dudes.
