Mars Calling

Genre: Hard Sci-Fi / Satirical Dystopia / Solarpunk The Earth is drowning, space is a subscription model, and the universe does not do bookkeeping. When the West Antarctic ice sheet liquefied and started sliding into the ocean with the sudden enthusiasm of a drunk man falling down an escalator, humanity didn't get a neat, predictable waterworld. Instead, it got Spheres - massive, spinning, two-million-ton doughnuts of titanium composite and recycled soda cans parked on the Interplanetary Superhighway.
Part cosmic rest stops and part giant kinetic batteries, the Spheres survive by using multi-mile carbon-nanotube tethers to "lasso" incoming colonial fleets, absorbing their momentum to sling cargo freighters out to the deep mining colonies of Mars and other far destinations. Enter Kenji, a hyper-precise appraiser obsessed with right angles, contractual density, and floorboards that shouldn't tilt.
Living in the cramped, lower-class pods of Sphere 1, Kenji is forced to share his life support with wealthy climate refugees , whose luxury infinity pools and automated apple orchards are actively draining the heat and water from the struggling citizens below. To make matters worse, the corporate overlords hide this grim reality behind blindingly bright, neon-pink morale screens featuring glitching cartoon sloths and winking tomatoes that scream "SMILE! LIFE SUPPORT IS A SUBSCRIPTION!".
But when Kenji intercepts a classified corporate directive, the corporate illusions shatter. The Conglomerate has slated Sphere 1 for decommissioning-meaning they plan to vent the atmosphere, abandon the residents, and melt down the station's chassis to build drill bits for Jupiter. Alongside Amara, a cynical forest programmer , Artie, a hot-tempered Cockney engineer , and Captain Daisy, an agoraphobic pilot who commands the station's tethers , Kenji refuses to be liquidated.
Together, this band of blue-collar technicians launches a meticulous, data-driven rebellion to hijack the station's automated infrastructure. Blending sweeping, hard sci-fi ingenuity with witty, dry observational charm, Mars Calling is a brilliant, laugh-out-loud, and deeply human look at what happens when the apocalypse gets managed by an accounting department, and why you should never underestimate people who know how to use a tape measure.
