Another notes post, i thought you might find this interesting.

Mission to Mars

Let us presume that in the darkness!potterverse mars, venus, and their—and our—moon[s] have ley lines and are candidates for terraforming(and mageforming).

Let us also presume that harry has the political clout to create a corporation that use technomancy to hide magic within technology and operate openly as they begin preparing to first scan, then send robotic landers (actually controlled by paintings and using custom floos for communication), and finally a 'manned'—though also goblins, house elves, and darklings—mission to verify the information.

With the information verified and they know mars is possible to inhabit, we begin the process by building greenhouses for foodstuffs and underground shelters to inhabit during the terraforming process.

What follows are a few steps. Your mission, should you choose to accept it, is write plausible ways for the potterverse to make these happen WITHOUT the average fanon bs like magical cores as well as add any other steps i've missed.

The story will have this taking place over a century at least with the first colonial buildings being built from materials there—or in belt—beginning in approximately 2017 and finished by 2031.

The use of rockets is superseded by mass accelerators as well, only using magic for structural integrity and lightness of metal, making faux-alloys that are trade secrets and left unpatented due to not being able to say 'well we did it with magic, actually.'

Harry's assets:

Muggles with space exploration experience, rocket scientists, and so on, most spouses or parents of magicals, the rest read in by an icw edict.

Technomancers from around the world

His own private research and technical development dept

A SHIELDesque intelligence agency, sanctioned by the ICW AND NATO nations, though few to none of the nations know about the magical aspect, just that REDACTED* are very effective agents.

His darklings who can spy on anyone—save the goblins—without being detected.

An encyclopedia, in the middle of collating all knowledge and distilling it to the bare minimum for inclusion into the project, staffed by hundreds of knowledgeable witches and wizards.

A tome, linking him to the tomes of his ancestors who wielded the darkness before him where they recorded their thoughts, rare spells they learned or created, and the like. Pointless for this project but still an asset.

Significant public goodwill due to his name in public and his philanthropic projects.

Good to excellent relations with every magical country—save china and south Africa which are neutral to him due to his reputation—due to his encyclopedia research groups' ambassadorial system.

In essence, his encyclopedia and their ancillary projects such as REDACTED and R&TD has become a de facto government of its own, an accident but useful they find, even if it's all ministry and no ministered at the moment.

Hermione's names for projects when turned into an acronym are always bad. Her adult and relatives support environment (magical computers that parents can bbs chat with other muggleborns' parents or order stuff from diagon alLey for their kids) acronym as arse. [Any ideas to turn that into arsenal actually?]

Steps:

Increase mass of moons to create tidal lock on core

Increase mass of mars to increase gravitational pull

Increase spin of mars to increase gravitational pull?

Lock moons to stable orbits

Introduce a runaway greenhouse effect

Reliquify core of mars to restart magnetic fields, via tunneling golems?

Create golems to seed fauna and biomass, creating a simplified ecosystem prior to introducing all magical fauna and flora.

Use magic to pull ore and predominantly ice remnants from asteroid belt, sterilize ice prior to crashing onto mars. Leave ore orbiting and bring it down magically? Crash it on the moons so industry is done there while mars is to be paradisiacal?

Raise atlantis and transfer it to mars after adding a glass onion dome over it.

Colony layout:

The first colony will be seven uk sized [eventual] arcologies surrounding a greenland sized biodome with olympus mons at the fourth spot at the 135 degree point if seen on a map. Each arcology is connected by a bullet train track to the closest two in a circle with more bullet trains from each arcology making spokes to the central biodome. Food production takes place all underground.

Each arcology will be designed to eventually hold 7 contiguous levels of human residential space with six park layers between them. Hogwarts's mars campus is on the opposite side of the planet or on Atlantis.

Atlantis is to float above olympus mons.

Eventual growth will have more colony-states based on the same layout, named for each continent. Eight spokes radiating off a central preserve with the 135 degree spoke always being some natural formation or a second preserve.

Magical creatures can have their own domes or live in preserves or migrate between the two at will. Goblins reside inside olympus mons, slowly expanding from there. Dwarves build their colony-state within pavonis mons and extending deeper than the goblins. Selkies do not emigrate until the oceans are properly seeded. Dragons eventually fly free when there's an atmosphere.

Harry's private arcology tops olympus, completing its shape but adding spires of gold and crystal, making it look like a glass castle atop the mountain(design commissioned by sirius). (I know it may still be active. In this story, it's not and if it was, goblins would have their own magic to deal with diverting magma or shielding from it and utilizing it.)

The rich will be able to build 1-3 mile circumference crystal domes that float in a matrix somewhere that sounds incredibly rich. Much like puritan mews in transmetropolitan.

*no name yet but i kinda want to come up with an acronym from REDACTED for the organization. Fairly unlikely. Maybe something like magic or mage?
