How close are we to cheap space launch?When does a ride to orbit get cheap?
or, simply: When does a ride to orbit get cheap?or, precisely: How close are we to cheap space launch?
Reusable first stages have cut the price of orbit by more than 90% since the Shuttle, but the sub-$100/kg goal depends on rapid full reuse that Starship has not yet demonstrated.Rockets can now land and fly again, which made space far cheaper - but the truly cheap ticket needs a whole rocket you can reuse in days, and nobody has that yet.
China recovers an orbital-launch first stage - A Long March-10B first stage returned under control and was caught by a net on a sea platform, China's first controlled carrier-rocket recovery. Recovery was achieved; reflight and lower launch cost were not yet demonstrated. Next up - First upper-stage (Ship) tower catch attempt (expected 2027).
State of playWhere cheap space launch stands right now
The current stage, the honest metric, and the single threshold that gates the next stage. Each threshold is a falsifiable claim with a named next test.How far up the ladder we've climbed, the honest verdict, and the one thing blocking the next step.

The thresholds that gate the next stageWhat has to happen next
Each threshold is a falsifiable claim with a named next test; the gap chart shows how far today's metric sits from the goal.Each row is one thing that has to be proven — and how far today's number is from the target.
The record behind the verdict
Major events set large; context events set small but never hidden. Everything below the TODAY rule is a schedule, not a result.
The expendable era - high $/kg
The expendable era - high $/kg begins with sputnik 1 - first orbital launch. The result established the next question for the field.
The Shuttle's false promise of reuse
The Shuttle's false promise of reuse moved the field from space shuttle first flight (sts-1) to dc-x delta clipper vertical landing. The results narrowed the next question without closing it.
Partial reuse - Falcon 9
Partial reuse - Falcon 9 moved the field from falcon 1 reaches orbit to starlink drives rapid falcon 9 reuse. The results narrowed the next question without closing it.
Toward full reuse - Starship
Toward full reuse - Starship moved the field from starship first integrated flight test to full rapid reuse of both stages. The results narrowed the next question without closing it.
Events outside the declared eras
Events outside the declared eras begins with target: sub-$100/kg to orbit. The result established the next question for the field.

Read the evidence more closely
Definitions, system boundaries and experimental caveats behind the headline record.
01Partial reuse is mature at fleet scale
As of 31 March 2026, Falcon 9 had completed approximately 620 orbital launches, with 39 of 40 Q1 2026 Falcon missions using flight-proven boosters; the maximum demonstrated first-stage life was then 34 flights. This shows mature partial reuse at fleet scale, not full reuse.
02Qualified lifetime is not demonstrated lifetime
Falcon boosters are now described as qualified for up to 40 flights, versus the achieved record of 36 by 9 July 2026. Qualification, demonstrated flights and economically useful lifetime should remain separate fields.
03The upper stage remains expendable
Falcon 9's second stage remains expendable. Fairing halves and the first stage are recovered, but every flight still requires a newly manufactured orbital stage-the major architectural difference from the rapid-full-reuse threshold.
04The cost reduction is company-reported
SpaceX reports that partial reuse reduced cost per tonne by approximately 85% relative to a historical average of $18,500/kg. This is a company-reported cost comparison, not a public customer price or independently audited marginal launch cost.
05Manifested payload changes effective cost
Falcon missions averaged approximately 13 tonnes delivered per launch from 2023 onward, materially below the advertised 22.8-tonne maximum. Price divided by maximum capacity therefore understates effective dollars per manifested kilogram on typical missions.
06Starship's V3 capacity is still a design target
Starship V3 is designed for 100 tonnes to orbit in a fully reusable configuration; this was not demonstrated by Flight 12. SpaceX still described operational payload delivery as expected in the second half of 2026 and identified Ship catch and reflight as remaining milestones.
07New Glenn's reuse case is unproven
New Glenn's first stage is designed for at least 25 flights and up to 45 tonnes to low Earth orbit, but one landing does not validate that lifetime, refurbishment burden or launch economics.
If the remaining tests pass
Downstream capabilities, drawn dashed because they depend on results not yet in.
Who is building it-and what the money saysCapital, institutions and the global race
The teams doing the work, where they are based, and whether the money points to real delivery or only a plan.Company finance, public programmes, institutional leadership and market evidence-kept separate from valuations, forecasts and announced capacity.
Cheap launch is led by SpaceX's operational partial reuse, with public-company accounts showing how capital-intensive the challengers remain. Rocket Lab and Firefly have real revenue, but backlog is not revenue; Stoke and Isar have fresh financing, but their next-generation vehicles have not established reliable orbital cadence or lower cost.
