From tkwa.me

Mercury was the smallest planet of the Solar System and the closest to the Sun. It was disassembled between 2030 and 2035 to supply the Solar Dyson swarm. Its rock and metal became collectors, factories, radiators and stored feedstock. Protected geological fragments survived in orbital custody.[4][5]

Physical characteristics

Mercury had a mean radius of 2,440 kilometres and a mass of 3.30 × 10²³ kilograms. Its eccentric orbit had a semimajor axis of 57.9 million kilometres, or 0.387 astronomical units. A year lasted 88 Earth days. Its 3:2 spin–orbit resonance gave it three rotations every two orbits; sunrise to sunrise took 176 Earth days.[1]

A large iron-rich core lay beneath a comparatively thin rocky mantle and crust. Impacts had excavated basins including Caloris, while planetary contraction had raised long scarps. Mercury had a tenuous exosphere, extreme day–night temperatures and ice in permanently shadowed polar craters. It had no natural moons. Mariner 10 and MESSENGER supplied early spacecraft surveys.[2]

Disassembly

Mercury combined abundant construction material, intense sunlight and a shallow gravitational well. Its initial escape velocity was 4.3 kilometres per second. Planetary disassembly required roughly 1.8 × 10³⁰ joules merely to overcome its gravitational binding; refining, transport and equipment losses added to the bill.[1][3]

Beginning in 2030, replicating industrial fleets mined and refined the surface, then used electromagnetic launchers to send material into solar orbit. Atomically precise manufacturing produced thin mirrors, supports and power equipment. Collectors returned energy through beam handoff corridors. More power supported more mining and more collectors, so removal accelerated as the installation grew.[4]

Armstrong and Sandberg’s 2013 paper Eternity in six hours had described this feedback process. Its illustrative model took about 31 years and assumed a five-year interval between extraction and operating collectors. The 2030–2035 programme used a much larger industrial seed and commissioning cycles measured in weeks or months. Most material left during the final expansion, after the early factories had multiplied.[3][4]

Migrating launch grids rebuilt their foundations as excavation lowered the surface. Operators continually recalculated trajectories as the remaining mass and gravity declined. Launch streams were balanced to control recoil; receiving tugs separated the material into solar orbits before dense traffic developed. Exposed core material passed through core cooling fields, where separated streams and droplets radiated heat before collection. Orbital material depots held surplus metal and silicates until factories needed them. By the swarm’s completion in 2035, no planet remained at Mercury’s former orbit.[4]

Preserved terrain

The Mercury reserve dispute protected 2,140 polar crater floors under a boundary fixed in 2033. During final disassembly, fleets lifted the retained ground as intact fragments into shaded, refrigerated enclosures. The ruling preserved designated matter while the surrounding planet became industrial feedstock. Later geological asylum programmes gave displaced landscapes legal representation through guardian intelligences, which could refuse relocation on behalf of a cliff.[5][6]

Material legacy

Mercury’s dispersed matter supported industries throughout the inner Solar System. Claims on its collectors passed through sunbeam inheritance, allowing descendants to receive income from sunlight intercepted by ancestral machinery. Observatories outside Earth’s protected solar sightline bought eclipse reservations from collector operators. The former planet’s material continued to cast shadows, now at times specified in contracts.[6]

The loss of Mercury prompted an InfiniteForum discussion about who could authorize planetary disassembly, whether preserved fragments replaced a landscape, and who received the resulting energy income.[7]
