Routing the Sky

Hacker Anthology

In 2025, SpaceX stops renting spectrum and buys it—flipping AWS‑4/H‑block into a 2 GHz MSS backbone and lighting a 15,000‑satellite LEO/VLEO swarm with optical links that behave like dark fiber in orbit. Ordinary phones see the sky as Band 23; terrestrial small cells mirror the band on the ground. The pitch is ruthless and elegant: route around borders, wholesale to carriers, and make failover a firmware default. Gwynne Shortwell, SpaceX’s unflappable dealmaker, becomes both architect and lightning rod—threading FCC rulemakings, ITU timelines, and 3GPP edge cases while coaxing chip vendors to bless the bands. Mentor‑antagonist Jessica Rosenworth wants safety first and legible policy; spectrum grandmaster Charlie Ergon plays ally and trap‑setter; T‑Mobile toggles between partner and rival. The central question lands with orbital precision: can Shortwell keep a sovereign‑agnostic network truly neutral once everyone needs it? The first crucible hits like a landfall: a catastrophic hurricane snaps towers; phones silently roam to MSS; lives are saved—then a rare handover edge case bricks a beloved handset on the way back to terrestrial. Lawsuits stack. CTIA and European telcos demand power caps and carve‑outs. A rushed modem fix exposes a Band‑23 power‑control quirk, quietly weaponized by a foreign service to herd protesters into satellite mode for mass geolocation. Trade journalist Rachel Jouett turns filings and firmware into front‑page stakes, even as a whistleblower hints at a compromised supplier and a rogue payload buried in the flock. Standards meetings feel like courtrooms, and BGP‑like pathing on the laser mesh becomes a new venue for policy: which packets get priority when every beam is a lane? As the constellation scales, orbital traffic rules harden, insurers invent “satellite life policies,” and a geomagnetic storm drags hundreds of VLEO craft into luminous, unsettling reentries. The Space Development Agency leans on priority lanes; forty nations serve simultaneous subpoenas for the shadow internet’s routes. Rosenworth pushes for fail‑safe failover and public‑safety guarantees. Investors salivate; rivals circle; environmental researchers warn about alumina in the upper atmosphere. In a world where firmware defaults are ethics and routing tables read like treaties, Shortwell faces the choice that will define the sky: hold the mesh neutral and global—or fracture it along the borders it was built to ignore.
