Google and AT&T invest in Starlink rival for satellite-to-smartphone service

Original Article ↗ Hacker News Discussion ↗

Google and AT&T’s investment in AST SpaceMobile, which aims to provide direct satellite-to-smartphone connectivity, is prompting debate over whether any newcomer can realistically compete with SpaceX’s Starlink given SpaceX’s dominance in low-cost launches and massive existing constellation. Commenters weigh launch economics, antitrust concerns, and analogies to AWS/Netflix and MVNOs, arguing over how risky it is to rely on a powerful supplier that is also a downstream rival. Others focus on technical trade-offs—AST’s few large, complex satellites versus Starlink’s many cheaper ones—as well as spectrum limits, astronomical light pollution, and whether the satellite internet market is big enough to support multiple players.

AT&T, Google, and Strategic Motives

  • Some see AT&T’s long-term performance and past missteps (DirecTV, TimeWarner) as a red flag, though others note it’s now a more focused company.
  • Google’s involvement triggers skepticism about long-term commitment, given its reputation for killing projects, but also seen as a sign of serious capital backing.
  • Several view satellite-to-smartphone as a huge, non-zero-sum market where multiple players can coexist rather than a simple “Starlink rival” fight.

Reliance on SpaceX as a “Competitor”

  • A central debate: can AST SpaceMobile truly compete with Starlink while buying launches from SpaceX?
  • One side argues dependence on a dominant launch provider undermines competition and creates strategic risk.
  • Others counter:
    • Launch services and broadband are distinct markets.
    • Analogies: Netflix on AWS vs Amazon Video, MVNOs on incumbent mobile networks, store brands on the same shelves as branded goods.
    • Antitrust and “common carrier” style obligations could constrain SpaceX from discriminatory behavior.

Launch Economics and Market Power

  • SpaceX’s much lower $/kg launch cost is seen as a massive competitive advantage; other launchers are said to be 3.5–6x more expensive.
  • Some wonder why SpaceX doesn’t raise prices; proposed reasons include:
    • Growing overall launch demand.
    • Maintaining a strong cost differentiator.
    • Avoiding antitrust scrutiny and signaling neutrality.
  • Debate over whether SpaceX is effectively a monopoly and if regulators will ever intervene meaningfully.

AST SpaceMobile’s Technical and Business Model

  • AST’s approach: fewer, very large satellites with complex antenna tech vs Starlink’s many small, disposable sats.
  • Supporters say this is more manageable in aggregate (fewer maneuvers) and better aligned with direct-to-smartphone use.
  • Skeptics raise concerns:
    • Huge capex, pre-revenue status, and harsh public markets.
    • Collision risk, micrometeoroids, station-keeping propellant, and cost per satellite.
    • Sensitivity to launch costs, especially if not using SpaceX.

Space, Spectrum, and Externalities

  • Some argue orbital “congestion” and spectrum scarcity should be treated like utilities or regulated shared infrastructure.
  • Astronomy impact is acknowledged: Starlink glare has reportedly improved with mitigation, but large constellations and huge antennas remain controversial.
  • Enthusiasm exists for the broader “virtuous cycle” of cheaper launches driving new space applications, even as ethical and aesthetic concerns persist.
