Why Space Launch Got So Much Cheaper
Reusable boosters cut the cost per kilogram to orbit about twentyfold. What the numbers really show, what stayed expensive and where Starship stands.
THE SHORT ANSWER
Launch cost to low Earth orbit fell about twentyfold in NASA's comparison of a Space Shuttle with a Falcon 9, from $54,500 to $2,720 per kilogram. Reuse did it, not lower prices. The comparison sets a Shuttle cost against a Falcon 9 list price, and people, deep space and station cargo remain expensive.

The number everyone quotes
The most-cited comparison comes from a 2018 NASA Ames paper by Harry Jones. It puts a Space Shuttle launch at about $1.5 billion for 27,500 kg to low Earth orbit, or $54,500 per kilogram. It puts a Falcon 9 launch at its then-advertised price of $62 million for 22,800 kg, or $2,720 per kilogram. The conclusion is a drop by a factor of about 20.
Treat that factor as a range, not a constant, for three reasons.
- The Shuttle’s cost depends on the accounting. NASA’s own Shuttle fact sheet gives the average cost to prepare and launch one mission in fiscal year 2010 as about $775 million, roughly half of the paper’s figure. The same sheet says the whole programme cost $113.7 billion, not adjusted for inflation. Per-mission cost and full programme cost give very different answers.
- The Falcon 9 figure is a price, not a cost. SpaceX does not publish what a launch costs it. Every per-kilogram figure for Falcon 9 is a list price or an outside estimate.
- Cargo to the space station saves less. For deliveries to the International Space Station, Falcon 9 and Dragon together cost about $140 million for 6,000 kg, or $23,300 per kilogram, because the capsule itself adds cost and mass. Jones puts the saving there at a factor of about 4.
What got cheaper, and what did not
The sticker price did not fall. Falcon 9’s list price has gone up in nominal terms: $62 million in 2018, $67 million after a March 2022 increase that SpaceX attributed to inflation, and $74 million on its current standard payment plan, which runs through 2026.
By our arithmetic, $74 million divided by the roughly 22,000 kg that SpaceX lists as the maximum to low Earth orbit comes to about $3,400 per kilogram. That is a list price set against the largest mass a fully expendable rocket can carry, so it is a best case for the reused rocket, not a measure of what it costs. A reused booster carries less, which pushes the real figure higher.
What fell is the cost of the part that used to be thrown away. SpaceX explains the economics simply: it re-flies the most expensive parts of the rocket. The first stage steers back through the atmosphere using four grid fins at its top, and lands on a drone ship or on land. The upper stage is still expendable, and the reuse is partial.
How much reuse, how fast
The published record for a first stage is 37 flights. Booster B1067 flew its 37th mission on 25 August 2026, according to Space.com, and the record still stood at the end of October. Falcon 9 flew 165 missions in 2025, all successful, and Space.com says that is more than all other orbital rockets combined. The 118th Falcon 9 launch of 2026 took place on 31 October. Space.com expects just under 150 for the year. About three quarters of the 2026 flights carry the company’s own Starlink satellites.
Reuse is a story about cadence as much as about hardware: the more often a booster flies, the more flights share its cost.
What is still expensive
Cheap launch to orbit did not make everything cheap.
- Sending people. NASA’s Office of Inspector General estimated about $55 million per seat on Crew Dragon, around 2019, against about $90 million for Boeing’s Starliner and about $86 million for Soyuz.
- Deep space on a government rocket. The same office estimated $4.1 billion per launch for at least the first four Artemis missions, counting production and ground operations but not development.
- Everything beyond orbit. SpaceX’s own Starship page quotes $100 million per metric ton, or $100,000 per kilogram, for delivering cargo to the Moon or Mars, starting no earlier than 2028.
Where Starship fits
Starship is designed to be fully reusable and to carry more than 100 tonnes. SpaceX’s own wording about full reuse still describes it as work in progress. Space.com’s October 2026 reporting says Starship is still under development and that operational flights are a future milestone. NASA says SpaceX still plans to demonstrate in-space propellant transfer, which the lunar lander depends on, on an uncrewed mission, and it has not been demonstrated yet.
So the honest statement is this: Starship is a test programme, and its cost per kilogram is a goal, not a measurement. Falcon 9 is the rocket that has changed the numbers so far.
What to watch next
- Cadence, not price: how many flights each booster makes and how often the fleet launches.
- Whether the upper stage ever comes back: that is where the next large saving sits.
- Independent cost data: list prices are not costs, and the gap is what matters for competitors.
- Starship milestones: an orbital flight is not an operational service. Look for propellant transfer and payload delivery to orbit.
Our take: reuse worked; the sticker price did not fall. Cost to orbit fell by roughly a factor of twenty on NASA’s comparison, more than an order of magnitude, because the expensive hardware flies again and again, not because rockets became cheap to build. The next step needs the second stage to come back too.
Questions and answers
How much cheaper is a Falcon 9 than the Space Shuttle?
A 2018 NASA analysis found about $2,720 per kilogram to low Earth orbit for Falcon 9 and $54,500 for the Shuttle, roughly twenty times less. NASA's own Shuttle fact sheet gives lower Shuttle costs, so the factor depends on accounting.
How many times can a Falcon 9 booster fly?
The published record is 37 flights, by booster B1067 on 25 August 2026, according to Space.com. The second stage is not reused.
Is Starship operational?
No. As of November 2026 it is a development and test programme. Space.com says operational flights are a future milestone, and in-space propellant transfer for the lunar lander has not yet been demonstrated.
Is launch cost the real cost?
No. The per-kilogram figures for Falcon 9 are list prices or outside estimates. SpaceX does not publish what a launch costs it.
