The cost of launching payload to low Earth orbit has fallen by over 97% since the Space Shuttle era, from $54,500/kg to approximately $1,500/kg on a reusable SpaceX Falcon 9. This page compares every major launch vehicle by cost per kilogram, payload capacity, reusability, and status. SpaceX Starship targets another order-of-magnitude reduction to $100-200/kg, which would fundamentally transform the economics of every space industry segment.
Cost per kilogram to LEO for every major launch vehicle, sorted from most expensive to least. Costs are approximate and reflect typical mission profiles. Reusable configurations reduce marginal costs significantly but may reduce payload capacity.

Launch cost history can be divided into four distinct eras, each representing a structural shift in how rockets are built, priced, and operated.
Cost-plus contracts, expendable vehicles, national prestige programs
Competition introduced by SpaceX Falcon 1/9, ULA monopoly challenged
Falcon 9 booster reuse, 90%+ cost reduction vs. Shuttle era
Starship, Neutron, Terran R targeting rapid, airline-like reusability
Starlink (7,000+ satellites, ~$10B deployment) would cost $380B at Shuttle-era pricing. SpaceX's $1,500/kg made it possible. Amazon Kuiper and OneWeb follow the same economics. Mega-constellations are a direct product of launch cost reduction.
Varda Space Industries can only justify microgravity pharmaceutical manufacturing if launch costs are low enough for the product value to exceed the launch cost. At $1,500/kg, a 100kg capsule costs ~$150K to launch. At Shuttle pricing, it would cost $5.4M.
CubeSats and smallsats proliferated because rideshare on Falcon 9 ($275K for 50kg) made orbit accessible to universities, startups, and developing nations. Dedicated small launchers (Electron, Firefly) add schedule and orbit flexibility.
At $54,500/kg, sending a 80kg person to orbit costs $4.4M in launch costs alone. At $1,500/kg, it drops to $120K. At Starship's target of $200/kg, it would be $16K -- approaching adventure tourism pricing. Each cost step unlocks larger demand.
Astroscale, Orbit Fab, and ClearSpace can only build business cases for servicing existing satellites if they can affordably launch servicing vehicles. The $1,500/kg era makes it cheaper to launch a service mission than to launch a replacement satellite in many cases.
NASA's Artemis program depends on Starship as the Human Landing System. At current SLS pricing ($26,000/kg to LEO), sustained lunar presence is unaffordable. Starship at $200/kg makes lunar cargo economical at ~$1,000-2,000/kg to lunar surface with refueling architecture.
SpaceX Starship represents the most consequential development in launch economics since the Falcon 9 reusability breakthrough. If achieved, sub-$200/kg costs would expand the space addressable market by an order of magnitude.
Even if Starship initially achieves 10x its target cost ($1,000-2,000/kg), it would still be competitive with Falcon 9 while delivering 7x more payload. The critical assumptions are: full and rapid reusability of both stages (not yet demonstrated for the upper stage), high flight cadence (dozens of flights per vehicle per year), and low refurbishment costs. SpaceX's track record with Falcon 9 booster reuse (20+ flights per booster) suggests these targets are ambitious but not unprecedented.
Launch cost is the most important number in the space economy. The 97% reduction from $54,500/kg (Shuttle) to $1,500/kg (Falcon 9 reusable) created the modern commercial space industry: Starlink, Planet Labs, Varda, and the entire NewSpace ecosystem exist because of this cost curve. Starship represents the next step function -- if SpaceX achieves $200/kg, the addressable market for space applications expands by another order of magnitude, enabling industrial-scale manufacturing, tourism, and sustained lunar/Mars logistics. The question is not whether launch costs will continue to fall, but how fast and how far.
