WtW Ghost Gala - Day 5: Jack O'Lantern
Share an interesting fact you found while doing research for your WIP
Space Elevators and Space Winches
A key part of my WIP's plot requires a fast way to get from Earth into orbit at short notice. My initial idea was a space elevator, but now I'm wondering if a space winch wouldn't serve me better.
(A very good video on space elevator technology here.)
Basically, in the alternative future where Fate is the Half of It takes place (late 21st century), humanity is much farther into the space age than we can reasonably expect to be by the same point in our IRL timeline. There's a functioning Moon base, there's a lot of infrastructure in orbit (including the ARK Corporation's ever-growing Orbital Sanctuary project), and normally, travel from Earth into orbit wouldn't be a huge deal.
Short-notice evacuation following a nuclear strike alert, however, isn't normal. I have the system to quickly get the pre-approved evacuees to their assigned launch points, but the more traditional route of using shuttles isn't the safest when there are nukes flying through the air. Which is why I considered a space elevator. I was even prepared to handwave the fact that even in a world where space elevators are possible, it would be extremely unfeasible to have more than one per planet. (If the writers of Halo can do it, why can't I?)
However, I encountered a bigger problem. A space elevator requires a tether to be connected to the surface, which makes it vulnerable to destruction, shockwaves, etc. caused by nukes. And if the tether snaps, it's major yikes time for people on the elevator, people at the top, and a good chunk of the planet at the bottom. And my story needed:
The initial evacuation to be successful.
The planet-side elevator structure to remain intact, even if not functioning 200 years later. With very little maintenance. Yeah.
Which led me to looking into a space winch: something that would have a stable base in orbit, but no permanent connection to the surface. A discussion about that on Space Stack Exchange was useful (emphasis mine):
So instead of a big tower going into orbit with cables like an elevator, what if we had a satellite in orbit, something that can move to various orbits and positions. This satellite has a long cable it drops to the earth to pre-determined "Bear Traps" like we do to help land helicopters onto Frigates in rough seas. Once the cable is secured payloads are loaded, the bear trap released, and the whole thing reeled in to the orbiting satellite. ... [the cable] would likely have to be "shot" out towards the earth to a point where gravity will pull it down, or the end of the cable would need some sort of thrust guidance system to guide it out of its orbit and towards the earth. I would also imagine that the orbiting satellite would have correctional thrusters to stabilize it's orbit against the forces of pulling up extra mass from the surface.
And this is something that I believe I can make work with a little bit of sc-fi! The pre-determined evacuation points can have "lifeboat" type pods, all set to be picked up by the cable launched from the respective satellites. Things like movement speed, trajectory stability and survival of the occupants - well, that's what suspension of disbelief is for. And the planetside structure, being ridiculously smaller and simpler than a whole-ass elevator, stands a much better chance of remaining intact 200 years later.
(Now let's hope that none of the multiple winches get the cables tangled, because that would be... bad.)
P.S. No, we can't have teleporters yet because plot reasons.
P. P.S. The Moon base will be another subject for research. I expect to be drawing a lot of inspiration from Andy Weir's Artemis.

Augmented Hearts: Bonnie
Had a wee bit of art block and decided to make another VN picture to get over it, this time it's sunset at the beach with Bonnie. Human worlds are a little too warm for most vectra, but maybe a hot dog and the player's company can make up for it. 🌭🏖️🌅
