Space logistics is the planning and execution of everything needed to move hardware, supplies and people from the ground into space, between orbits and back again. It is the supply chain of the space economy. A satellite that is finished on time but has no launch slot, no license, no transport to the launch site or no way to reach its final orbit does not deliver any value. This guide explains the four stages of space logistics, who does what, which documents and deadlines matter, and how the market is changing.
Space logistics in one sentence
Space logistics answers one question: how does the right object get to the right place in space, at the right time, in the right condition and at an acceptable cost? On Earth, that question involves trucks, ships and warehouses. In space, it involves rockets, adapters, dispensers, orbital transfer vehicles, cargo spacecraft, ground stations and a long list of approvals.
Why demand is growing so fast
The numbers from NASA's Small Spacecraft Technology State of the Art report show the scale. In 2025, 4,577 spacecraft were launched, nearly 60% more than in 2024. Starlink accounted for about 70% of them. Of the remaining spacecraft, 45% had a mass of 200 kg or less. NASA also notes that small satellites are getting heavier: launches of small satellites between 11 and 600 kg grew by about 10% in 2025.
To serve this demand, the rideshare market has grown quickly. NASA attributes this to more launch providers, better launch capabilities, and adapters and dispensers designed specifically for small satellites and CubeSats. More options are good news for satellite operators, but they also make planning harder. Every rocket has its own interfaces, schedules, documents and prices.
The four stages of space logistics
1. Ground logistics: from factory to launch pad
Before launch, a spacecraft goes through environmental testing, including vibration, shock and thermal vacuum tests. It is then shipped to the launch site in a controlled container and processed there. SpaceX's Rideshare Payload User's Guide shows how detailed this stage is: it defines temperature, humidity and cleanliness levels for each processing phase, and payloads must be cleaned to the "visibly clean, highly sensitive" standard before integration. Our guide to the launch campaign covers the work at the spaceport.
2. Launch logistics: buying and preparing the ride
This stage covers choosing a rocket and securing a seat. Customers decide between a rideshare or a dedicated launch, compare small launchers with heavy rockets, and plan around launch windows. Costs are covered in our article How much does it cost to launch a satellite?, and the booking process in How to book a rideshare launch.
According to NASA, launch integration for a primary spacecraft typically involves the launch service provider, the spacecraft manufacturer, the spacecraft customer, the launch range and sometimes a launch broker or integrator. On rideshare missions, integration becomes more complex because of its multi-customer, multi-mission nature.
3. In-space logistics: the last mile and beyond
A rideshare usually drops satellites into a shared orbit. NASA notes that the primary mission determines that orbit, so it rarely matches every secondary payload perfectly. This is where orbital transfer vehicles come in. NASA describes them as vehicles with onboard propulsion that are launched to an approximate orbit and then move to one or more target orbits to deploy small spacecraft or host payloads. They are often called space tugs, although NASA notes that many in the industry are moving away from that term.
In-space logistics also includes resupply. The ISS supply chain depends on cargo spacecraft such as Northrop Grumman's Cygnus, shown on the cover approaching the station in August 2024 with about 8,200 pounds (roughly 3,700 kg) of science and supplies. Further out, NASA's CLPS program buys delivery of payloads to the Moon, and in-orbit servicing extends the life of satellites already in space.
4. Return and end of life
Logistics does not end in orbit. Experiments and products have to come back to Earth, and satellites must be removed at the end of their mission. SpaceX's rideshare guide, for example, expects all payloads to follow the FCC rule that spacecraft be disposed of as soon as practicable and no later than five years after the mission ends. The options are explained in satellite end of life: deorbit or graveyard orbit.
Who does what in space logistics
- Launch service provider: Operates the rocket and sells capacity
- Launch broker: Matches a spacecraft with a launch opportunity, usually as a rideshare
- Launch integrator: Ensures compatibility through analyses and physical integration, and may supply the dispenser or separation system
- Launch range: Provides the launch site and enforces range safety
- Orbital transfer vehicle operator: Moves payloads from the drop-off orbit to the target orbit
- Cargo spacecraft operator: Resupplies stations and returns cargo
- Ground station operator: Provides contact with the satellite after separation
The definitions of broker and integrator follow NASA's report: a broker typically coordinates the relationship between customer and launch provider without additional integration services, while an integrator performs analyses and physical integration.
Paperwork is logistics too
NASA stresses that the spacecraft owner or operator is responsible for licensing, whether or not an integrator is involved. That can include radio frequency licensing, remote sensing licensing and laser usage approval. Launch providers and integrators require proof of licensing before integration, plus safety analyses and documents such as orbital debris information, materials and venting data, and spacecraft models. Rideshare payloads also follow "do no harm" rules that protect the other satellites on the same rocket, for example restrictions on transmitters, deployments after separation and hazardous materials. See spectrum licensing and ITU filings and range safety and launch licensing.
A typical timeline
SpaceX's rideshare guide gives a concrete example of how long the chain is. Mission analysis inputs are due around eight months before launch, range safety submissions start around six months before launch, and a launch campaign readiness review happens about two months before launch. Payloads arrive at the launch site around 30 days before liftoff. Logistics planning therefore starts long before the satellite is finished.
Key terms
- Upmass: cargo launched from Earth to space.
- Downmass: cargo returned from space to Earth.
- Manifest: the list of payloads assigned to a launch.
- Dedicated rideshare: a launch carrying only small satellites, without a large primary payload (NASA definition).
- Last mile: transport from the drop-off orbit to the final orbit.
- ICD: Interface Control Document, the agreed technical interface between payload and launch vehicle.
Frequently asked questions
What does space logistics mean?
It is the planning and transport of hardware, supplies and people to, within and from space. It includes testing and shipping on the ground, launch booking and integration, in-orbit transfer, resupply, return and disposal.
Who provides space logistics services?
Launch providers, brokers and integrators, operators of orbital transfer vehicles, cargo spacecraft operators, ground station networks and servicing companies.
How is space logistics different from launch?
Launch is one step in the chain. Space logistics also covers the months of preparation before launch and everything that happens after separation.
How early does space logistics planning start?
For a SpaceX rideshare, the first mission analysis inputs are due about eight months before launch, and licensing often has to start even earlier.
Why is space logistics becoming more important?
Launch numbers are rising quickly, and more providers, orbits and services mean more options to compare and coordinate.
